Each pattern has 3 components: a filter that defines -which flows a replacement applies to, a regular expression that defines what -gets replaced, and a target value that defines what is substituted in. - -Replace hooks fire when either a client request or a server response is -received. Only the matching flow component is affected: so, for example, if a -replace hook is triggered on server response, the replacement is only run on -the Response object leaving the Request intact. You control whether the hook -triggers on the request, response or both using the filter pattern. If you need -finer-grained control than this, it's simple to create a script using the -replacement API on Flow components. - -Replacement hooks are extremely handy in interactive testing of applications. -For instance you can use a replace hook to replace the text "XSS" with a -complicated XSS exploit, and then "inject" the exploit simply by interacting -with the application through the browser. When used with tools like Firebug and -mitmproxy's own interception abilities, replacement hooks can be an amazingly -flexible and powerful feature. - - -On the command-line -------------------- - -The replacement hook command-line options use a compact syntax to make it easy -to specify all three components at once. The general form is as follows: - -.. code-block:: none - - /patt/regex/replacement - -Here, **patt** is a mitmproxy filter expression, **regex** is a valid Python -regular expression, and **replacement** is a string literal. The first -character in the expression (``/`` in this case) defines what the separation -character is. Here's an example of a valid expression that replaces "foo" with -"bar" in all requests: - -.. code-block:: none - - :~q:foo:bar - -In practice, it's pretty common for the replacement literal to be long and -complex. For instance, it might be an XSS exploit that weighs in at hundreds or -thousands of characters. To cope with this, there's a variation of the -replacement hook specifier that lets you load the replacement text from a file. -To specify a file as replacement, prefix the file path with ``@``. -You might start **mitmdump** as follows: - ->>> mitmdump --replacements :~q:foo:@~/xss-exploit - -This will load the replacement text from the file ``~/xss-exploit``. - -The ``--replacements`` flag can be passed multiple times. - - -Interactively -------------- - -The :kbd:`R` shortcut key in the mitmproxy options menu (:kbd:`O`) lets you add and edit -replacement hooks using a built-in editor. The context-sensitive help (:kbd:`?`) has -complete usage information. - -================== ======================= -command-line ``--replacements`` -mitmproxy shortcut :kbd:`O` then :kbd:`R` -================== ======================= |
