µWeb

h1. Request

The request object in µWeb makes sure each request from the browser, independent of coming from a mod_python instance or the [[standalone]] server looks the same.

You can reach the request object inside a [[pagemaker]] by using the self.req variable.

It is presented as an object with the following members:

* env

* headers

h2. Post vars

POST arguments can be found under: self.post and should be accessed by issueing a 'getfirst()', or 'getlist()' call for the desired key.

self.post.getfirst() allows for a second argument to set a default if the desired key isn't set by the browser

<pre>

<code class="html">

argA = self.post.getfirst('argA')

argB = self.post.getfirst('argB', 'empty')

if 'argA' in self.post:

  #pass, argA has been send by the browser

</code>

</pre>

h2. Get vars

GET arguments can be found under: self.get, they work the same as POST vars.

h2. Cookies

self.cookies contains the cookies send by the browser, as the interface to create them from the server.

h3. Retrieving a cookie

You can fetch the content of cookie by accessig the self.cookie dict with the name of the desired cookie as its key.

The returned cookie object has a value member containing the actual value of the requested cookie.

<pre>

<code class="python">

self.cookies['sample'].value

</code>

</pre>

h2. ENV

The env variable is a dictionary containing the following items;

* CONTENT_TYPE

* CONTENT_LENGTH

* HTTP_COOKIE

* HTTP_HOST

* HTTP_REFERER

* HTTP_USER_AGENT

* PATH_INFO

* QUERY_STRING

* REMOTE_ADDR

* REQUEST_METHOD

* UWEB_MODE 'STANDALONE' / 'MOD_PYTHON'

h3. Extended env

If more detail is required about the environment, you can issue a call to the self.req.ExtendedEnvironment() method, which will inject more details into the env var. This is a much slower operation than the normal env call, so that's why its tucked away in a separate method.

* AUTH_TYPE

* CONNECTION_ID

* DOCUMENT_ROOT

* RAW_REQUEST

* REMOTE_HOST

* REMOTE_USER

* SERVER_NAME

* SERVER_PORT

* SERVER_LOCAL_NAME

* SERVER_LOCAL_IP

* SERVER_PROTOCOL

And in case of a @mod_python@ setup you will also get:

* MODPYTHON_HANDLER

* MODPYTHON_INTERPRETER

* MODPYTHON_PHASE
