Here's a complete mitmproxy script -that adds a new header to every HTTP response before it is returned to the -client: - -$!example("examples/add_header.py")!$ - -The first argument to each event method is an instance of ScriptContext that -lets the script interact with the global mitmproxy state. The __response__ -event also gets an instance of Flow, which we can use to manipulate the -response itself. - -We can now run this script using mitmdump or mitmproxy as follows: - -<pre class="terminal"> -> mitmdump -s add_header.py -</pre> - -The new header will be added to all responses passing through the proxy. - - - -## Events - -### start(ScriptContext, argv) - -Called once on startup, before any other events. - - -### clientconnect(ScriptContext, ClientConnect) - -Called when a client initiates a connection to the proxy. Note that -a connection can correspond to multiple HTTP requests. - - -### serverconnect(ScriptContext, ServerConnection) - -Called when the proxy initiates a connection to the target server. Note that -a connection can correspond to multiple HTTP requests. - -### request(ScriptContext, Flow) - -Called when a client request has been received. The __Flow__ object is -guaranteed to have a non-None __request__ attribute. - - -### response(ScriptContext, Flow) - -Called when a server response has been received. The __Flow__ object is -guaranteed to have non-None __request__ and __response__ attributes. - - -### error(ScriptContext, 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. The __Flow__ -object is guaranteed to have non-None __request__ and __error__ attributes. - - -### clientdisconnect(ScriptContext, ClientDisconnect) - -Called when a client disconnects from the proxy. - -### done(ScriptContext) - -Called once on script shutdown, after any other events. - - -## API - -The main classes you will deal with in writing mitmproxy scripts are: - -<table class="table"> - <tr> - <th>libmproxy.flow.ClientConnection</th> - <td>Describes a client connection.</td> - </tr> - <tr> - <th>libmproxy.flow.ClientDisconnection</th> - <td>Describes a client disconnection.</td> - </tr> - <tr> - <th>libmproxy.flow.Error</th> - <td>A communications error.</td> - </tr> - <tr> - <th>libmproxy.flow.Flow</th> - <td>A collection of objects representing a single HTTP transaction.</td> - </tr> - <tr> - <th>libmproxy.flow.Headers</th> - <td>HTTP headers for a request or response.</td> - </tr> - <tr> - <th>libmproxy.flow.ODict</th> - - <td>A dictionary-like object for managing sets of key/value data.

You can view the API documentation -using pydoc (which is installed with Python by default), like this: - -<pre class="terminal"> -> pydoc libmproxy.flow.Request -</pre> - - -## Running scripts in parallel - -We have a single flow primitive, so when a script is handling something, other requests block. -While that's a very desirable behaviour under some circumstances, scripts can be run threaded by using the <code>libmproxy.script.concurrent</code> decorator. - -$!example("examples/nonblocking.py")!$ - -## Running scripts on saved flows - -Sometimes, we want to run a script on __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 on the -[mitmdump](@!urlTo("mitmdump.html")!@) page). 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__, __response__, __error__, __done__. If -the flow doesn't have a __response__ or __error__ associated with it, the -matching event will be skipped. |
