Sirius3 hat geschrieben:@peddy: zeig Deinen ganzen Code hier, sonst raten wir ewig.
Nichts lieber als das.
Ich habe noch mal die Doku von Flask gewälzt und habe das gefunden.
Code: Alles auswählen
a = request.args.get('a', 0, type=int)
b = request.args.get('b', 0, type=int)
Note that we are using the get() method here which will never fail. If the key is missing a default value (here 0) is returned. Furthermore it can convert values to a specific type (like in our case int). This is especially handy for code that is triggered by a script (APIs, JavaScript etc.) because you don’t need special error reporting in that case.
Hier ist die App:

The debugger caught an exception in your WSGI application. You can now look at the traceback which led to the error.
To switch between the interactive traceback and the plaintext one, you can click on the "Traceback" headline. From the text traceback you can also create a paste of it. For code execution mouse-over the frame you want to debug and click on the console icon on the right side.
You can execute arbitrary Python code in the stack frames and there are some extra helpers available for introspection:
dump() shows all variables in the frame
dump(obj) dumps all that's known about the object
Brought to you by DON'T PANIC, your friendly Werkzeug powered traceback interpreter.
