10 Detailed Solutions to AWS WAF Challenges with CapSolver
Here are ten comprehensive solutions, ranging from basic integration to advanced scenarios, to help you solve AWS WAF challenges using CapSolver Dashboard
.
Solution 1: Basic AWS WAF Token Solving (ProxyLess)
This is the most common scenario where AWS WAF presents a JavaScript challenge, and you need to obtain an aws-waf-token
cookie. CapSolver's AntiAwsWafTaskProxyLess
task type is ideal for this.
Steps:
- Make an initial request to the target URL protected by AWS WAF.
- Parse the HTML response to extract critical parameters:
key
,iv
,context
, andchallengeJS
. - Send these parameters to CapSolver using the
createTask
endpoint withAntiAwsWafTaskProxyLess
. - Poll the
getTaskResult
endpoint until the task isready
. - Extract the
aws-waf-token
cookie from CapSolver's solution. - Use this cookie in subsequent requests to access the protected content.
Code Example (Python):
python
import requests
import re
import time
CAPSOLVER_API_KEY = "YOUR_CAPSOLVER_API_KEY"
CAPSOLVER_CREATE_TASK_ENDPOINT = "https://api.capsolver.com/createTask"
CAPSOLVER_GET_TASK_RESULT_ENDPOINT = "https://api.capsolver.com/getTaskResult"
WEBSITE_URL = "https://efw47fpad9.execute-api.us-east-1.amazonaws.com/latest" # Example URL
def solve_aws_waf_captcha_proxyless(website_url, capsolver_api_key):
client = requests.Session()
response = client.get(website_url)
script_content = response.text
key_match = re.search(r'"key":"([^"]+)"', script_content)
iv_match = re.search(r'"iv":"([^"]+)"', script_content)
context_match = re.search(r'"context":"([^"]+)"', script_content)
jschallenge_match = re.search(r'<script.*?src="(.*?)".*?></script>', script_content)
key = key_match.group(1) if key_match else None
iv = iv_match.group(1) if iv_match else None
context = context_match.group(1) if context_match else None
jschallenge = jschallenge_match.group(1) if jschallenge_match else None
if not all([key, iv, context, jschallenge]):
print("Error: AWS WAF parameters not found in the page content.")
return None
task_payload = {
"clientKey": capsolver_api_key,
"task": {
"type": "AntiAwsWafTaskProxyLess",
"websiteURL": website_url,
"awsKey": key,
"awsIv": iv,
"awsContext": context,
"awsChallengeJS": jschallenge
}
}
create_task_response = client.post(CAPSOLVER_CREATE_TASK_ENDPOINT, json=task_payload).json()
task_id = create_task_response.get('taskId')
if not task_id:
print(f"Error creating CapSolver task: {create_task_response.get('errorId')}, {create_task_response.get('errorCode')}")
return None
print(f"CapSolver task created with ID: {task_id}")
for _ in range(10):
time.sleep(5)
get_result_payload = {"clientKey": capsolver_api_key, "taskId": task_id}
get_result_response = client.post(CAPSOLVER_GET_TASK_RESULT_ENDPOINT, json=get_result_payload).json()
if get_result_response.get('status') == 'ready':
aws_waf_token_cookie = get_result_response['solution']['cookie']
print("CapSolver successfully solved the CAPTCHA.")
return aws_waf_token_cookie
elif get_result_response.get('status') == 'failed':
print(f"CapSolver task failed: {get_result_response.get('errorId')}, {get_result_response.get('errorCode')}")
return None
print("CapSolver task timed out.")
return None
# Example usage:
# aws_waf_token = solve_aws_waf_captcha_proxyless(WEBSITE_URL, CAPSOLVER_API_KEY)
# if aws_waf_token:
# print(f"Received AWS WAF Token: {aws_waf_token}")
# final_response = requests.get(WEBSITE_URL, cookies={"aws-waf-token": aws_waf_token})
# print(final_response.text)
Solution 2: AWS WAF Token Solving with Proxies
For more robust scraping operations, especially when dealing with aggressive WAFs or IP-based restrictions, using proxies with CapSolver is essential. This solution is similar to Solution 1 but incorporates proxy usage.
Steps:
- Follow steps 1 and 2 from Solution 1 to extract WAF parameters.
- Send these parameters to CapSolver using the
createTask
endpoint withAntiAwsWafTask
and include your proxy details. - Poll the
getTaskResult
endpoint until the task isready
. - Extract the
aws-waf-token
cookie. - Use this cookie with your proxy in subsequent requests.
Code Example (Python - Task Payload modification):
python
# ... (previous code for imports and parameter extraction)
task_payload = {
"clientKey": capsolver_api_key,
"task": {
"type": "AntiAwsWafTask", # Use AntiAwsWafTask for proxy support
"websiteURL": website_url,
"awsKey": key,
"awsIv": iv,
"awsContext": context,
"awsChallengeJS": jschallenge,
"proxy": "http:user:pass@ip:port" # Example: "http:your_user:[email protected]:8080"
}
}
# ... (rest of the code for creating task and getting result remains the same)
Solution 3: Handling 405 Response Codes with Key, IV, Context
Sometimes, the initial request to an AWS WAF protected page might return a 405 status code, and the necessary key
, iv
, and context
parameters are embedded directly in the HTML. This scenario requires careful parsing.
Steps:
- Make an HTTP GET request to the
websiteURL
. - If the response status code is 405, parse the HTML content to find
window.gokuProps = {"key":"AQID...","iv":"A6we...","context":"rGXm.."}
or similar structures to extractkey
,iv
, andcontext
. - Submit these parameters to CapSolver using
AntiAwsWafTask
orAntiAwsWafTaskProxyLess
. - Retrieve the
aws-waf-token
and proceed.
Code Example (Python - Parameter Extraction):
python
import requests
import re
WEBSITE_URL = "https://efw47fpad9.execute-api.us-east-1.amazonaws.com/latest"
response = requests.get(WEBSITE_URL)
script_content = response.text
if response.status_code == 405:
key_match = re.search(r'"key":"([^"]+)"', script_content)
iv_match = re.search(r'"iv":"([^"]+)"', script_content)
context_match = re.search(r'"context":"([^"]+)"', script_content)
# ... (extract jschallenge if present)
key = key_match.group(1) if key_match else None
iv = iv_match.group(1) if iv_match else None
context = context_match.group(1) if context_match else None
# ... (use these parameters with CapSolver)
else:
print(f"Unexpected status code: {response.status_code}")
Solution 4: Handling 202 Response Codes with awsChallengeJS
In other cases, an AWS WAF protected page might return a 202 status code, and only the awsChallengeJS
parameter is required. The key
, iv
, and context
can be ignored in this specific scenario.
Steps:
- Make an HTTP GET request to the
websiteURL
. - If the response status code is 202, parse the HTML content to find the
challenge.js
link. - Submit
websiteURL
andawsChallengeJS
to CapSolver. - Retrieve the
aws-waf-token
and proceed.
Code Example (Python - Parameter Extraction):
python
import requests
import re
WEBSITE_URL = "https://example.com/protected-202"
response = requests.get(WEBSITE_URL)
script_content = response.text
if response.status_code == 202:
jschallenge_match = re.search(r'<script.*?src="(.*?challenge.js)".*?></script>', script_content)
jschallenge = jschallenge_match.group(1) if jschallenge_match else None
if jschallenge:
# ... (use websiteURL and jschallenge with CapSolver)
pass
else:
print("awsChallengeJS not found.")
else:
print(f"Unexpected status code: {response.status_code}")
Solution 5: AWS WAF Image Recognition (Grid Type)
When AWS WAF presents an image-based CAPTCHA, specifically a grid-type challenge (e.g.,
¡°Choose all the beds¡±), CapSolver¡¯s AwsWafClassification
task type can solve it.
Steps:
- Identify that the AWS WAF challenge is an image recognition task, specifically a grid type.
- Extract the base64 encoded images from the challenge page.
- Determine the
question
(e.g.,aws:grid:bed
). - Send the
websiteURL
,images
(as a list of base64 strings), andquestion
to CapSolver using thecreateTask
endpoint withAwsWafClassification
. - CapSolver will directly return the solution, which includes the
objects
(indices of the correct images) orbox
(coordinates forcarcity
type).
Code Example (Python - Image Recognition):
python
import capsolver
import base64
import requests
import re
capsolver.api_key = "YOUR_CAPSOLVER_API_KEY"
WEBSITE_URL = "https://example.com/aws-waf-image-challenge" # Example URL with image challenge
def solve_aws_waf_image_captcha(website_url, capsolver_api_key):
# This part would involve scraping the page to get the base64 images and the question
# For demonstration, let's assume we have them:
# In a real scenario, you'd use a headless browser or advanced parsing to get these.
# Example: response = requests.get(website_url)
# images_base64 = re.findall(r'data:image/png;base64,([a-zA-Z0-9+/=]+)', response.text)
# question_match = re.search(r'"question":"(aws:grid:[a-zA-Z]+)"', response.text)
# question = question_match.group(1) if question_match else "aws:grid:bed"
# Placeholder for actual scraped data
images_base64 = ["/9j/4AAQSkZJRgABAgAA...", "/9j/2wCEAAoHBwgH..."] # Replace with actual base64 images
question = "aws:grid:bed" # Replace with actual question from the page
if not images_base64 or not question:
print("Error: Image data or question not found.")
return None
try:
solution = capsolver.solve({
"type": "AwsWafClassification",
"websiteURL": website_url,
"images": images_base64,
"question": question
})
print("CapSolver successfully solved the image CAPTCHA.")
return solution
except Exception as e:
print(f"CapSolver image task failed: {e}")
return None
# Example usage:
# image_solution = solve_aws_waf_image_captcha(WEBSITE_URL, capsolver.api_key)
# if image_solution:
# print(f"Received Image Solution: {image_solution}")
# # The solution will contain 'objects' for grid type, indicating which images to select.
Solution 6: AWS WAF Image Recognition (Toy Car City Type)
Another common image recognition challenge is the "toy car city" type, where you need to place a dot at the end of a car's path. CapSolver also supports this with AwsWafClassification
.
Steps:
- Identify the challenge as a "toy car city" type.
- Extract the base64 encoded image.
- Use the
question
aws:toycarcity:carcity
. - Send the
websiteURL
,images
(single base64 string), andquestion
to CapSolver. - CapSolver will return the
box
coordinates (x, y) where the dot should be placed.
Code Example (Python - Toy Car City Recognition):
python
import capsolver
import base64
capsolver.api_key = "YOUR_CAPSOLVER_API_KEY"
WEBSITE_URL = "https://example.com/aws-waf-toycar-challenge" # Example URL
def solve_aws_waf_toycar_captcha(website_url, capsolver_api_key):
# Placeholder for actual scraped data
image_base64 = "/9j/4AAQSkZJRgABAgAA..." # Replace with actual base64 image
question = "aws:toycarcity:carcity"
if not image_base64:
print("Error: Image data not found.")
return None
try:
solution = capsolver.solve({
"type": "AwsWafClassification",
"websiteURL": website_url,
"images": [image_base64],
"question": question
})
print("CapSolver successfully solved the toy car city CAPTCHA.")
return solution
except Exception as e:
print(f"CapSolver toy car city task failed: {e}")
return None
# Example usage:
# toycar_solution = solve_aws_waf_toycar_captcha(WEBSITE_URL, capsolver.api_key)
# if toycar_solution:
# print(f"Received Toy Car City Solution: {toycar_solution}")
# # The solution will contain 'box' with x, y coordinates.
Solution 7: Real-time Parameter Parsing for Expired Tokens
AWS WAF tokens can expire quickly. If CapSolver returns an error like timeout metering, your parameters have expired
, it indicates that the awsKey
, awsIv
, awsContext
, or awsChallengeJS
are no longer valid. The solution is to parse these parameters in real-time for each request.
Steps:
- Implement a robust parsing mechanism to extract
key
,iv
,context
, andchallengeJS
immediately before sending the task to CapSolver. - Ensure your scraping logic retries the process with newly extracted parameters if an expiration error occurs.
- This approach minimizes the window for token expiration, enhancing the reliability of your AWS WAF solve.
Code Example (Python - Real-time Parsing Strategy):
python
def get_aws_waf_params(website_url):
client = requests.Session()
response = client.get(website_url)
script_content = response.text
key_match = re.search(r'"key":"([^"]+)"', script_content)
iv_match = re.search(r'"iv":"([^"]+)"', script_content)
context_match = re.search(r'"context":"([^"]+)"', script_content)
jschallenge_match = re.search(r'<script.*?src="(.*?)".*?></script>', script_content)
return {
"key": key_match.group(1) if key_match else None,
"iv": iv_match.group(1) if iv_match else None,
"context": context_match.group(1) if context_match else None,
"jschallenge": jschallenge_match.group(1) if jschallenge_match else None
}
def solve_aws_waf_with_retry(website_url, capsolver_api_key, max_retries=3):
for attempt in range(max_retries):
print(f"Attempt {attempt + 1} to solve AWS WAF challenge...")
params = get_aws_waf_params(website_url)
if not all(params.values()):
print("Failed to extract all AWS WAF parameters. Retrying...")
time.sleep(2) # Wait before retrying extraction
continue
# Construct task_payload using params and send to CapSolver
# ... (similar to Solution 1, but using the dynamically fetched params)
# Placeholder for CapSolver call and result retrieval
# For example:
# aws_waf_token = call_capsolver_api(website_url, capsolver_api_key, params)
# if aws_waf_token:
# return aws_waf_token
# else:
# print("CapSolver failed to return token. Retrying...")
# time.sleep(5) # Wait before retrying CapSolver call
print("Failed to solve AWS WAF challenge after multiple retries.")
return None
Solution 8: Using awsChallengeJS
when Key, IV, Context are Absent
Sometimes, the key
, iv
, and context
parameters might not be present on the page, but a challenge.js
link is available. In such cases, passing awsChallengeJS
to CapSolver is sufficient.
Steps:
- Scrape the target page and check for the presence of
challenge.js
. - If found, extract the URL of
challenge.js
. - Submit the
websiteURL
and the extractedawsChallengeJS
to CapSolver. - CapSolver will process the challenge and return the
aws-waf-token
.
Code Example (Python - awsChallengeJS
only):
python
# ... (imports and API key setup)
WEBSITE_URL = "https://example.com/challenge-js-only"
def solve_aws_waf_challenge_js(website_url, capsolver_api_key):
client = requests.Session()
response = client.get(website_url)
script_content = response.text
jschallenge_match = re.search(r'<script.*?src="(.*?challenge.js)".*?></script>', script_content)
jschallenge = jschallenge_match.group(1) if jschallenge_match else None
if not jschallenge:
print("Error: awsChallengeJS not found.")
return None
task_payload = {
"clientKey": capsolver_api_key,
"task": {
"type": "AntiAwsWafTaskProxyLess",
"websiteURL": website_url,
"awsChallengeJS": jschallenge
}
}
# ... (rest of the code for creating task and getting result remains the same as Solution 1)
Solution 9: Utilizing awsApiJs
for Dynamic challenge.js
In more complex scenarios, the challenge.js
URL might not be directly visible but is assembled from the code within jsapi.js
. CapSolver can handle this by accepting awsApiJs
.
Steps:
- Scrape the target page and look for
jsapi.js
. - Extract the URL of
jsapi.js
. - Submit the
websiteURL
and the extractedawsApiJs
to CapSolver. - CapSolver will then internally resolve the
challenge.js
and solve the AWS WAF challenge.
Code Example (Python - awsApiJs
):
python
# ... (imports and API key setup)
WEBSITE_URL = "https://example.com/jsapi-challenge"
def solve_aws_waf_api_js(website_url, capsolver_api_key):
client = requests.Session()
response = client.get(website_url)
script_content = response.text
jsapi_match = re.search(r'<script.*?src="(.*?jsapi.js)".*?></script>', script_content)
jsapi = jsapi_match.group(1) if jsapi_match else None
if not jsapi:
print("Error: awsApiJs not found.")
return None
task_payload = {
"clientKey": capsolver_api_key,
"task": {
"type": "AntiAwsWafTaskProxyLess",
"websiteURL": website_url,
"awsApiJs": jsapi
}
}
# ... (rest of the code for creating task and getting result remains the same as Solution 1)
Solution 10: Advanced awsProblemUrl
for Visual Challenges
For highly dynamic visual challenges where key
, iv
, context
, and challenge.js
are absent, but a problem
endpoint URL is present, CapSolver can use awsProblemUrl
.
Steps:
- Scrape the page to find the
problem
endpoint URL, which typically contains keywords likeproblem
andnum_solutions_required
. - This URL can often be found by searching for
visualSolutionsRequired
in the page HTML. - Submit the
websiteURL
and the extractedawsProblemUrl
to CapSolver. - CapSolver will interact with this endpoint to solve the visual AWS WAF challenge.
Code Example (Python - awsProblemUrl
):
python
# ... (imports and API key setup)
WEBSITE_URL = "https://example.com/problem-url-challenge"
def solve_aws_waf_problem_url(website_url, capsolver_api_key):
client = requests.Session()
response = client.get(website_url)
script_content = response.text
# Example of how to find awsProblemUrl (this might vary)
problem_url_match = re.search(r'"problemUrl":"(https://.*?problem\?.*?)"', script_content)
problem_url = problem_url_match.group(1) if problem_url_match else None
if not problem_url:
print("Error: awsProblemUrl not found.")
return None
task_payload = {
"clientKey": capsolver_api_key,
"task": {
"type": "AntiAwsWafTaskProxyLess",
"websiteURL": website_url,
"awsProblemUrl": problem_url
}
}
# ... (rest of the code for creating task and getting result remains the same as Solution 1)

FAQ
Q1: What is AWS WAF and why does it pose a challenge for web scraping?
A1: AWS WAF (Web Application Firewall) is a security service that protects web applications from common web exploits. It challenges requests to differentiate between legitimate human users and automated bots, often using CAPTCHAs or JavaScript challenges. This poses a challenge for web scraping because automated scripts are designed to mimic human behavior, but WAFs are specifically designed to detect and block such automation.
Q2: How does CapSolver help in solving AWS WAF challenges?
A2: CapSolver is an AI-powered CAPTCHA solving service that automates the process of solving various CAPTCHA types, including those deployed by AWS WAF. It provides APIs for both token-based challenges (generating aws-waf-token
cookies) and image recognition challenges (solving visual puzzles), allowing scrapers to proceed with their requests without manual intervention.
Q3: Is real-time parameter parsing necessary for AWS WAF challenges?
A3: Yes, real-time parameter parsing is crucial. AWS WAF tokens and challenge parameters often have short lifespans. If these parameters expire before being used, CapSolver will return an error. Extracting key
, iv
, context
, challengeJS
, or awsProblemUrl
immediately before sending them to CapSolver ensures that you are always using fresh, valid data, significantly increasing the success rate of your AWS WAF solve.
Q4: Can CapSolver handle both JavaScript and image-based AWS WAF challenges?
A4: Yes, CapSolver is designed to handle both. For JavaScript challenges that require generating an aws-waf-token
, it offers AntiAwsWafTask
and AntiAwsWafTaskProxyLess
task types. For image-based CAPTCHAs, such as grid or toy car city types, it provides the AwsWafClassification
task type, which returns the correct selections or coordinates.
Q5: What are the benefits of using proxies with CapSolver for AWS WAF?
A5: Using proxies with CapSolver (via AntiAwsWafTask
) enhances the robustness of your web scraping operations. Proxies help in rotating IP addresses, making it harder for AWS WAF to detect and block your requests based on IP reputation or rate limiting. This is particularly beneficial for large-scale scraping or when targeting websites with aggressive anti-bot measures, ensuring higher success rates and preventing IP bans.
