Python bottle module causes "Error: 413 Request Entity Too Large"

Using Python's module bottle, I'm getting HTTP 413 error when posting requests of body size > bottle's internal MEMFILE_MAX constant. Minimal working example is shown below.

Server part (server.py):

from bottle import *

@post('/test')
def test():
    return str(len(request.forms['foo']));

def main():
    run(port=8008);

if __name__ == '__main__':
    main();

Client part (client.py):

import requests

def main():
    url = 'http://127.0.0.1:8008/test';

    r = requests.post(url, data={ 'foo' : 100000 * 'a' });
    print(r.text);

    r = requests.post(url, data={ 'foo' : 200000 * 'a' });
    print(r.text);

if __name__ == '__main__':
    main();

The first request prints:

100000

The second request prints:

...
<body>
    <h1>Error: 413 Request Entity Too Large</h1>
    <p>Sorry, the requested URL <tt>&#039;http://127.0.0.1:8008/test&#039;</tt>
       caused an error:</p>
    <pre>Request to large</pre>
</body>
....

I have absolutely no idea how to increase the bottle's internal limit. Is there any simple way to increase the limit, allowing requests of size, e.g., 1 MB?

Solution

  • You should be able to just

    import bottle
bottle.BaseRequest.MEMFILE_MAX = 1024 * 1024 # (or whatever you want)

    This appears to be the only way based on the source
