This patch does the following: - Fixes all warnings in the doc tree - Adds a modd + devd conf file that renders HTML and treats doc warnings as errors. This lets you send warning output to your desktop notifier, and gives livereload similar to the livehtml entry in the Makefile. - Some small tweaks Sphinx currently has a bug that causes unknown options to generate a warning: https://github.com/sphinx-doc/sphinx/issues/2229 This is fixed in stable, but not yet released. You can update Sphinx to the latest stable like so: pip install --upgrade https://github.com/sphinx-doc/sphinx/archive/stable.zip

mitmproxy
|
|
=========
|
|
|
|
**mitmproxy** is a console tool that allows interactive examination and
|
|
modification of HTTP traffic. It differs from mitmdump in that all flows are
|
|
kept in memory, which means that it's intended for taking and manipulating
|
|
small-ish samples. Use the :kbd:`?` shortcut key to view, context-sensitive
|
|
documentation from any **mitmproxy** screen.
|
|
|
|
Flow list
|
|
---------
|
|
|
|
The flow list shows an index of captured flows in chronological order.
|
|
|
|
.. image:: screenshots/mitmproxy.png
|
|
|
|
- **1**: A GET request, returning a 302 Redirect response.
|
|
- **2**: A GET request, returning 16.75kb of text/html data.
|
|
- **3**: A replayed request.
|
|
- **4**: Intercepted flows are indicated with orange text. The user may edit
|
|
these flows, and then accept them (using the :kbd:`a` key) to continue. In this
|
|
case, the request has been intercepted on the way to the server.
|
|
- **5**: A response intercepted from the server on the way to the client.
|
|
- **6**: The event log can be toggled on and off using the :kbd:`e` shortcut key. This
|
|
pane shows events and errors that may not result in a flow that shows up in the
|
|
flow pane.
|
|
- **7**: Flow count.
|
|
- **8**: Various information on mitmproxy's state. In this case, we have an
|
|
interception pattern set to ``.*``.
|
|
- **9**: Bind address indicator - mitmproxy is listening on port 8080 of all
|
|
interfaces.
|
|
|
|
|
|
Flow view
|
|
---------
|
|
|
|
The **Flow View** lets you inspect and manipulate a single flow:
|
|
|
|
.. image:: screenshots/mitmproxy-flowview.png
|
|
|
|
- **1**: Flow summary.
|
|
- **2**: The Request/Response tabs, showing you which part of the flow you are
|
|
currently viewing. In the example above, we're viewing the Response. Hit :kbd:`tab`
|
|
to switch between the Response and the Request.
|
|
- **3**: Headers.
|
|
- **4**: Body.
|
|
- **5**: View Mode indicator. In this case, we're viewing the body in **hex** mode. The other
|
|
available modes are **pretty**, which uses a number of heuristics to show you a friendly
|
|
view of various content types, and **raw**, which shows you exactly what's there without any
|
|
changes. You can change modes using the :kbd:`m` key.
|
|
|
|
|
|
Grid Editor
|
|
-----------
|
|
|
|
Much of the data that we'd like to interact with in mitmproxy is structured.
|
|
For instance, headers, queries and form data can all be thought of as a list of
|
|
key/value pairs. Mitmproxy has a built-in editor that lays this type of data
|
|
out in a grid for easy manipulation.
|
|
|
|
At the moment, the Grid Editor is used in four parts of mitmproxy:
|
|
|
|
- Editing request or response headers (:kbd:`e` for edit, then :kbd:`h` for headers in flow view)
|
|
- Editing a query string (:kbd:`e` for edit, then :kbd:`q` for query in flow view)
|
|
- Editing a URL-encoded form (:kbd:`e` for edit, then :kbd:`f` for form in flow view)
|
|
- Editing replacement patterns (:kbd:`o` for options, then :kbd:`R` for Replacement Patterns)
|
|
|
|
If there is is no data, an empty editor will be started to let you add some.
|
|
Here is the editor showing the headers from a request:
|
|
|
|

|
|
|
|
To edit, navigate to the key or value you want to modify using the arrow or vi
|
|
navigation keys, and press enter. The background color will change to show that
|
|
you are in edit mode for the specified field:
|
|
|
|
.. image:: screenshots/mitmproxy-kveditor-editmode.png
|
|
|
|
Modify the field as desired, then press escape to exit edit mode when you're
|
|
done. You can also add a row (:kbd:`a` key), delete a row (:kbd:`d` key), spawn an
|
|
external editor on a field (:kbd:`e` key). Be sure to consult the context-sensitive
|
|
help (:kbd:`?` key) for more.
|
|
|
|
Example: Interception
|
|
---------------------
|
|
|
|
**mitmproxy**'s interception functionality lets you pause an HTTP request or
|
|
response, inspect and modify it, and then accept it to send it on to the server
|
|
or client.
|
|
|
|
|
|
1: Set an interception pattern
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. image:: screenshots/mitmproxy-intercept-filt.png
|
|
|
|
We press :kbd:`i` to set an interception pattern. In this case, the ``~q`` filter
|
|
pattern tells **mitmproxy** to intercept all requests. For complete filter
|
|
syntax, see the :ref:`filters` section of the documentation,
|
|
or the built-in help function in **mitmproxy**.
|
|
|
|
2: Intercepted connections are indicated with orange text:
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. image:: screenshots/mitmproxy-intercept-mid.png
|
|
|
|
3: You can now view and modify the request:
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. image:: screenshots/mitmproxy-intercept-options.png
|
|
|
|
In this case, we viewed the request by selecting it, pressed :kbd:`e` for "edit"
|
|
and :kbd:`m` for "method" to change the HTTP request method.
|
|
|
|
4: Accept the intercept to continue:
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. image:: screenshots/mitmproxy-intercept-result.png
|
|
|
|
Finally, we press :kbd:`a` to accept the modified request, which is then sent on to
|
|
the server. In this case, we changed the request from an HTTP GET to
|
|
OPTIONS, and Google's server has responded with a 405 "Method not allowed".
