Ошибка 405 python

I’m trying to login to a website with a Python script using the requests library, but I keep getting a 405 error and I’m lost on why I’m getting it.

import requests

payload = {
'guid': 'xxxxx',
'password': "xxxx"
}

head = {'Host': 'www.blockchain.com',
'Connection': 'keep-alive',
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.94 Safari/537.36',
'Upgrade-Insecure-Requests': '1',
'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8',
'Accept-Encoding': 'gzip, deflate, br',
'Accept-Language': 'en-US,en;q=0.9'
    }

#This URL will be the URL that your login form points to with the "action" tag.
url_address = 'https://login.blockchain.com/#/login'

with requests.Session() as session:
    post = session.post(url_address, data=payload, headers = head, allow_redirects=True)

print(f'{post}')

I checked the form and the names of the inputfield seem to be correct as well.

What am I doing wrong in my code?

passname here
loginname here

The «Method Not Allowed» error code 405 in Flask is raised when the client makes a request using an HTTP method that is not supported by the endpoint being requested. This error occurs when the client makes a request using an HTTP method that the server is not configured to handle, such as a POST request when the endpoint only supports GET requests. This error can be fixed by properly configuring the endpoint to handle the intended HTTP method or by modifying the client’s request to match the supported methods of the endpoint.

Method 1: Use the correct HTTP method

To fix the «Method Not Allowed» error in Flask, you need to ensure that you are using the correct HTTP method for the endpoint. Here’s an example of how to do it:

from flask import Flask, request

app = Flask(__name__)

@app.route('/example', methods=['POST'])
def example():
    if request.method == 'POST':
        # Do something with the POST request
        return 'POST request successful'
    else:
        # Return a 405 error if the method is not allowed
        return 'Method Not Allowed', 405

In this example, we have defined an endpoint at /example that only accepts POST requests. If a GET request is made to this endpoint, Flask will automatically return a 405 Method Not Allowed error.

To ensure that the correct HTTP method is being used, we can check the request.method attribute. If it is not POST, we can return the 405 error ourselves.

This is just one way to fix the «Method Not Allowed» error in Flask. Other methods include allowing multiple HTTP methods for an endpoint using the methods parameter, or using a decorator like @app.route('/example', methods=['GET', 'POST']) to allow both GET and POST requests.

Method 2: Modify the endpoint to support the desired HTTP method

To fix the «Method Not Allowed» error in Flask, you can modify the endpoint to support the desired HTTP method. Here’s how to do it:

First, import the necessary modules:

from flask import Flask, request

Create a Flask app instance:

Define a view function that handles the desired HTTP method. In this example, we’ll use the GET method:

@app.route('/example', methods=['GET'])
def example():
    # Your code here
    return 'Hello, World!'

If you want to support additional HTTP methods, you can modify the methods parameter:

@app.route('/example', methods=['GET', 'POST'])
def example():
    if request.method == 'GET':
        # Handle GET request
        return 'Hello, World!'
    elif request.method == 'POST':
        # Handle POST request
        return 'Data received!'

In this example, the view function supports both GET and POST requests. You can add additional methods as needed.

Run the Flask app:

if __name__ == '__main__':
    app.run()

That’s it! By modifying the endpoint to support the desired HTTP method, you can fix the «Method Not Allowed» error in Flask.

Method 3: Handle the 405 error in a custom error handler

To handle the 405 error in Flask, you can create a custom error handler by using the errorhandler decorator. This decorator will register a function to handle any errors that occur in your Flask application.

from flask import Flask, jsonify

app = Flask(__name__)

@app.errorhandler(405)
def method_not_allowed(e):
    return jsonify(error=str(e)), 405

In the code above, we have created a custom error handler for the 405 error. The errorhandler decorator takes the error code as an argument and registers the function to handle that error.

The method_not_allowed function takes the error object as an argument and returns a JSON response with the error message and the status code 405.

You can also customize the error message by passing a string to the jsonify function.

from flask import Flask, jsonify

app = Flask(__name__)

@app.errorhandler(405)
def method_not_allowed(e):
    return jsonify(error="The method is not allowed for the requested URL."), 405

In the code above, we have customized the error message to make it more informative.

To test the custom error handler, you can create a route that returns a 405 error.

from flask import Flask

app = Flask(__name__)

@app.route('/example', methods=['POST'])
def example():
    return 'This route only allows GET requests.'

if __name__ == '__main__':
    app.run()

In the code above, we have created a route that only allows GET requests. If a user tries to make a POST request to this route, Flask will return a 405 error.

By using the custom error handler we created earlier, Flask will return a JSON response with the error message and the status code 405 instead of the default error page.

That’s how you can handle the 405 error in Flask with a custom error handler!

When building applications involving client-server communication, we must ensure that the client sends requests to the server using the correct HTTP method. The HTTP method, indicates the type of action that the client wants to perform on the requested resource. Examples of common HTTP methods include GET, POST, PUT, and DELETE.

However, if the client sends a request to the server using a method that the server can not handle, the server will respond with a “Method Not Allowed” error. HTTP status code of 405 indicates this error, and it can be a frustrating issue to troubleshoot. In this article, we will explore the causes of the “Method Not Allowed” error in Python and provide examples and solutions for resolving it.

There are several potential causes of the “Method Not Allowed” error in Python. Some of the most common causes include:

The client is using an outdated version of the API. If the client uses an outdated version of the API, it may not be able to send requests using the latest HTTP methods.
The client is sending a request to the wrong endpoint. If the client sends a request to the wrong endpoint, the server may not handle the request, even if it is the correct HTTP method.
The client is missing an authentication token or using an invalid token. If the server requires an authentication token in order to access certain resources, the client must include a valid token in its requests.
The server can not handle the requested method. Some servers can only handle certain methods and not others. Make sure to configure the servers so as to handle the requested method.
Some middleware, such as a security plugin, may be present to block certain types of requests. Make sure that any middleware present allows the requested method.

Example of the Error in Action

Here’s an example of how this error can occur in Python:

import requests
response = requests.patch('http://example.com/update')
print(response.status_code) # prints 405

In the above example, we are using the patch method to send a PATCH request to the server, but the server is not configured to handle PATCH requests. As a result, the server returns a 405 status code.

Solutions for Method Not Allowed error

Here are several solutions which we can use to resolve the “Method Not Allowed” error in Python. Some of the most effective solutions include:

Changing the method used in the requests function call to one that the server is configured to handle. For example, if the server is configured to handle PUT requests, you can change the method to put in the requests function call:

import requests

response = requests.put('http://example.com/update')
print(response.status_code) # prints 200

Updating the server configuration to handle the requested method. Add the appropriate routes and controllers to handle the requests on the server side.

if request.method == 'PATCH':
    # handle patch request
else:
    return "Method Not Allowed"

Checking the request headers that it has the correct content type and request version. If the headers are missing or incorrect, the server may not be able to handle the request properly.

headers = {'Content-Type': 'application/json', 'Accept': 'application/json'}
response = requests.patch('http://example.com/update', headers=headers)

Checking for any middleware, such as security plugins, that may be blocking the requested method. If a middleware is blocking the requested method, make sure to configure it to allow the method.
Make sure that the client is using the correct API endpoint. ALso, make sure that it is sending the request to the correct URL.
Ensure that the client has a valid authentication token and that it is present in the request headers.
If all else fails, it may be necessary to check the server’s error logs for more detailed information.
