Testing GET and POST calls using Flask

I was trying out Flask. In the process, I made a website that behaves like a server. It can help you test GET and POST calls.

It goes like this .

from flask import Flask, request
    app = Flask(__name__)
    
    @app.route('/method', methods=['GET', 'POST'])
    @app.route('/method/<wish>', methods=['GET', 'POST'])
    def method_used(wish=None):
        if request.method == 'GET':
            if wish:
                if wish in dir(request):
                    ans = None
                    s = "ans = str(request.%s)" % wish
                    exec s
                    return ans
                else:
                    return 'This wish is not available. The following are the available wishes: %s' % [method for method in dir(request) if '_' not in method]
            else:
                return 'This is just a GET method'
        else:
            return "You are using POST"

When I run this, this follows:

C:\Python27\python.exe E:/Arindam/Projects/Flask_Practice/first.py
 * Restarting with stat
 * Debugger is active!
 * Debugger PIN: 581-155-269
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

Now lets try some calls. I am using the browser.

http://127.0.0.1:5000/method

This is just a GET method

http://127.0.0.1:5000/method/NotCorrect

This wish is not available. The following are the available wishes: ['application', 'args', 'authorization', 'blueprint', 'charset', 'close', 'cookies', 'data', 'date', 'endpoint', 'environ', 'files', 'form', 'headers', 'host', 'json', 'method', 'mimetype', 'module', 'path', 'pragma', 'range', 'referrer', 'scheme', 'shallow', 'stream', 'url', 'values']
