|
||||
before the response body is read.
|
||||
|
||||
*flow*
|
||||
A ``models.HTTPFlow`` object. At this point, the flow is
|
||||
guaranteed to have a non-none ``request`` and ``response``
|
||||
attributes, however the response will have no content.

|
||||
unless response streaming has been enabled.
|
||||
|
||||
* - .. py:function:: error(flow)
|
||||
- Called when a flow error has occurred, e.g. invalid server responses,
|
||||
or interrupted connections. This is distinct from a valid server HTTP

|
||||
|
||||
- Called when a client wants to establish a WebSockets connection. The
|
||||
WebSockets-specific headers can be manipulated to manipulate the
|
||||
handshake. The ``flow`` object is guaranteed to have a non-None
|

TCP Events
|
||||
----------
|
||||
|
||||
These events are called only if the connection is in :ref:`TCP mode
|
||||
<tcpproxy>`. So, for instance, TCP events are not called for ordinary HTTP/S
|
||||
connections.

Inline Scripts
|
||||
==============
|
||||
|
||||
**mitmproxy** has a powerful scripting API that allows you to modify flows
|
||||
on-the-fly or rewrite previously saved flows locally.
|
||||
|
||||
The mitmproxy scripting API is event driven - a script is simply a Python
|
||||
module that exposes a set of event methods. Here's a complete mitmproxy script
|
||||
that adds a new header to every HTTP response before it is returned to the
|
||||
client:
|
||||
|
||||
.. literalinclude:: ../../examples/add_header.py
|
||||
:caption: examples/add_header.py
|
||||
:language: python
|
||||
|
||||
All events that deal with an HTTP request get an instance of :py:class:`~mitmproxy.models.HTTPFlow`,
|
||||
which we can use to manipulate the response itself.
|
||||
|
||||
We can now run this script using mitmdump or mitmproxy as follows:
|
||||
|
||||
>>> mitmdump -s add_header.py
|
||||
|
||||
The new header will be added to all responses passing through the proxy.
|
||||
|
||||
Examples
|
||||
--------
|
||||
|
||||
mitmproxy comes with a variety of example inline scripts, which demonstrate many basic tasks.
|
||||
We encourage you to either browse them locally or on `GitHub`_.
|
||||
|
||||
|
||||
Events
|
||||
------
|
||||
|
||||
Script Lifecycle Events
|
||||
^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
.. py:function:: start(context)
|
||||
|
||||
Called once on startup, before any other events.
|
||||
|
||||
:param List[str] argv: The inline scripts' arguments.
|
||||
For example, ``mitmproxy -s 'example.py --foo 42'`` sets argv to ``["--foo", "42"]``.
|
||||
|
||||
.. py:function:: done(context)
|
||||
|
||||
Called once on script shutdown, after any other events.
|
||||
|
||||
Connection Events
|
||||
^^^^^^^^^^^^^^^^^
|
||||
|
||||
.. py:function:: clientconnect(context, root_layer)
|
||||
|
||||
Called when a client initiates a connection to the proxy. Note that
|
||||
a connection can correspond to multiple HTTP requests.
|
||||
|
||||
.. versionchanged:: 0.14
|
||||
|
||||
:param Layer root_layer: The root layer, which provides transparent access to all attributes of the
|
||||
:py:class:`~mitmproxy.proxy.RootContext`. For example, ``root_layer.client_conn.address``
|
||||
gives the remote address of the connecting client.
|
||||
|
||||
.. py:function:: clientdisconnect(context, root_layer)
|
||||
|
||||
Called when a client disconnects from the proxy.
|
||||
|
||||
.. versionchanged:: 0.14
|
||||
|
||||
:param Layer root_layer: see :py:func:`clientconnect`
|
||||
|
||||
.. py:function:: serverconnect(context, server_conn)
|
||||
|
||||
Called before the proxy initiates a connection to the target server. Note that

a connection can correspond to multiple HTTP requests.
|
||||
|

:param ServerConnection server_conn: The server connection object. It is guaranteed to have a
|
||||
non-None ``address`` attribute.
|
||||
|
||||

|
||||
|

HTTP Events
|
||||
^^^^^^^^^^^
|
||||
|
||||
.. py:function:: request(context, flow)
|
||||
|
||||
Called when a client request has been received. The ``flow`` object is
|
||||
guaranteed to have a non-None ``request`` attribute.
|
||||
|
||||
:param HTTPFlow flow: The flow containing the request which has been received.
|
||||
The object is guaranteed to have a non-None ``request`` attribute.
|
||||
|
||||
.. py:function:: responseheaders(context, flow)
|
||||
|
||||
Called when the headers of a server response have been received.
|
||||
This will always be called before the response hook.
|
||||
|
||||
:param HTTPFlow flow: The flow containing the request and response.
|
||||
The object is guaranteed to have non-None ``request`` and
|
||||
``response`` attributes. ``response.content`` will be ``None``,
|
||||
as the response body has not been read yet.
|
||||
|
||||
.. py:function:: response(context, flow)
|
||||
|
||||
Called when a server response has been received.
|
||||
|
||||
:param HTTPFlow flow: The flow containing the request and response.
|
||||
The object is guaranteed to have non-None ``request`` and
|
||||
``response`` attributes. ``response.body`` will contain the raw response body,
|
||||
unless response streaming has been enabled.
|
||||
|
||||
.. py:function:: error(context, flow)
|
||||
|
||||
Called when a flow error has occurred, e.g. invalid server responses, or
|
||||
interrupted connections. This is distinct from a valid server HTTP error
|
||||
response, which is simply a response with an HTTP error code.
|
||||
|
||||
:param HTTPFlow flow: The flow containing the error.
|
||||
It is guaranteed to have non-None ``error`` attribute.
|
||||
|
||||
WebSockets Events
|
||||
^^^^^^^^^^^^^^^^^
|
||||
|
||||
.. py:function:: websocket_handshake(context, flow)
|
||||
|
||||
Called when a client wants to establish a WebSockets connection.
|
||||
The WebSockets-specific headers can be manipulated to manipulate the handshake.
|
||||
The ``flow`` object is guaranteed to have a non-None ``request`` attribute.
|
||||
|
||||
:param HTTPFlow flow: The flow containing the request which has been received.
|
||||
The object is guaranteed to have a non-None ``request`` attribute.
|
||||
|
||||
TCP Events
|
||||
^^^^^^^^^^
|
||||
|
||||
.. py:function:: tcp_message(context, tcp_msg)
|
||||
|
||||
.. warning:: API is subject to change
|
||||
|
||||
If the proxy is in :ref:`TCP mode <tcpproxy>`, this event is called when it
|
||||
receives a TCP payload from the client or server.
|
||||
|
||||
The sender and receiver are identifiable. The message is user-modifiable.
|
||||
|
||||
:param TcpMessage tcp_msg: see *examples/tcp_message.py*
|
||||

||||
API
|
||||
---
|
||||
|
||||
The canonical API documentation is the code, which you can browse here, locally or on `GitHub`_.
|
||||
*Use the Source, Luke!*
|
||||
|
||||
The main classes you will deal with in writing mitmproxy scripts are:
|
||||
|
||||
:py:class:`mitmproxy.flow.FlowMaster`
|
||||
- The "heart" of mitmproxy, usually subclassed as :py:class:`mitmproxy.dump.DumpMaster` or
|
||||
:py:class:`mitmproxy.console.ConsoleMaster`.
|
||||
:py:class:`~mitmproxy.models.ClientConnection`
|
||||
- Describes a client connection.
|
||||
:py:class:`~mitmproxy.models.ServerConnection`
|
||||
- Describes a server connection.
|
||||
:py:class:`~mitmproxy.models.HTTPFlow`
|
||||
- A collection of objects representing a single HTTP transaction.
|
||||
:py:class:`~mitmproxy.models.HTTPRequest`
|
||||
- An HTTP request.
|
||||
:py:class:`~mitmproxy.models.HTTPResponse`
|
||||
- An HTTP response.
|
||||
:py:class:`~mitmproxy.models.Error`
|
||||
- A communications error.
|
||||
:py:class:`netlib.http.Headers`
|
||||
- A dictionary-like object for managing HTTP headers.
|
||||
:py:class:`netlib.certutils.SSLCert`
|
||||
- Exposes information SSL certificates.
|
||||
|
||||
|
||||
Running scripts in parallel
|
||||
---------------------------
|
||||
|
||||
We have a single flow primitive, so when a script is blocking, other requests are not processed.
|
||||
While that's usually a very desirable behaviour, blocking scripts can be run threaded by using the
|
||||
:py:obj:`mitmproxy.script.concurrent` decorator.
|
||||
**If your script does not block, you should avoid the overhead of the decorator.**
|
||||
|
||||

||||

|
||||
:language: python
|
||||
|
||||
Make scripts configurable with arguments
|
||||
----------------------------------------
|
||||
|
||||
Sometimes, you want to pass runtime arguments to the inline script. This can be simply done by
|
||||
surrounding the script call with quotes, e.g. ```mitmdump -s 'script.py --foo 42'``.
|
||||
The arguments are then exposed in the start event:
|
||||
|
||||
.. literalinclude:: ../../examples/modify_response_body.py

||||
:caption: examples/modify_response_body.py
|
||||
:language: python
|
||||
|
||||
Running scripts on saved flows
|
||||
------------------------------
|
||||
|
||||
Sometimes, we want to run a script on :py:class:`~mitmproxy.models.Flow` objects that are already
|
||||
complete. This happens when you start a script, and then load a saved set of flows from a file
|
||||
(see the "scripted data transformation" example :ref:`here <mitmdump>`).
|
||||
It also happens when you run a one-shot script on a single flow through the ``|`` (pipe) shortcut
|
||||
in mitmproxy.
|
||||
|
||||
In this case, there are no client connections, and the events are run in the following order:
|
||||
**start**, **request**, **responseheaders**, **response**, **error**, **done**.
|
||||
If the flow doesn't have a **response** or **error** associated with it, the matching events will
|
||||
be skipped.
|
||||
|
||||
Spaces in the script path
|
||||
-------------------------
|
||||
|
||||
By default, spaces are interpreted as a separator between the inline script and its arguments
|
||||
(e.g. ``-s 'foo.py 42'``). Consequently, the script path needs to be wrapped in a separate pair of
|
||||
quotes if it contains spaces: ``-s '\'./foo bar/baz.py\' 42'``.

FlowMaster
|
||||
==========
|
||||
|
||||
.. note::
|
||||
|
||||
We strongly encourage you to use :ref:`inlinescripts` rather than subclassing mitmproxy's FlowMaster.
|
||||
- Inline Scripts are equally powerful and provide an easier syntax.
|
||||
- Most examples are written as inline scripts.
|
||||
- Multiple inline scripts can be used together.
|
||||
- Inline Scripts can either be executed headless with mitmdump or within the mitmproxy UI.
|
||||
|
||||
|
||||
All of mitmproxy's basic functionality is exposed through the **mitmproxy**
|
||||
library. The example below shows a simple implementation of the "sticky cookie"
|
||||
functionality included in the interactive mitmproxy program. Traffic is
|
||||
monitored for ``Cookie`` and ``Set-Cookie`` headers, and requests are rewritten
|
||||
to include a previously seen cookie if they don't already have one. In effect,
|
||||
this lets you log in to a site using your browser, and then make subsequent
|
||||
requests using a tool like curl, which will then seem to be part of the
|
||||
authenticated session.

Overview
|
||||
=========
|
||||
|
||||
Mitmproxy has a powerful scripting API that allows you to control almost any
|
||||
aspect of traffic being proxied. In fact, much of mitmproxy's own core
|
||||
functionality is implemented using the exact same API exposed to scripters (see
|
||||
:src:`mitmproxy/builtins`).
|
||||
|
||||
Scripting is event driven, with named handlers on the script object called at
|
||||
appropriate points of mitmproxy's operation. Here's a complete mitmproxy script
|
||||
that adds a new header to every HTTP response before it is returned to the
|
||||
client:
|
||||
|
||||
.. literalinclude:: ../../examples/add_header.py
|
||||
:caption: :src:`examples/add_header.py`
|
||||
:language: python
|
||||
|
||||
All events that deal with an HTTP request get an instance of
|
||||
:py:class:`~mitmproxy.models.HTTPFlow`, which we can use to manipulate the
|
||||
response itself. We can now run this script using mitmdump or mitmproxy as
|
||||
follows:
|
||||
|
||||
>>> mitmdump -s add_header.py
|
||||
|
||||
The new header will be added to all responses passing through the proxy.
|
||||
|
||||
|
||||
mitmproxy comes with a variety of example inline scripts, which demonstrate
|
||||
many basic tasks.
