WSGI request and response object

Project description Documentation Status

WebOb provides objects for HTTP requests and responses. Specifically it does this by wrapping the WSGI request environment and response status/headers/app_iter(body).

The request and response objects provide many conveniences for parsing HTTP request and forming HTTP responses. Both objects are read/write: as a result, WebOb is also a nice way to create HTTP requests and parse HTTP responses.

1.6.2 (2016-10-14)


  • WebOb’s exceptions will lazily read underlying variables when inserted into templates to avoid expensive computations/crashes when inserting into the template. This had a bad performance regression on Py27 because of the way the lazified class was created and returned. See

1.6.1 (2016-05-20)


  • Response.from_file now parses the status line correctly when the status line contains an HTTP with version, as well as a status text that contains multiple white spaces (e.g 404 Not Found). See

1.6.0 (2016-03-15)


  • Python 3.2 is no longer supported by WebOb
