Currently, its most- +supported method of use is from the XPCOM shell, where you can get all the +dynamicity of JS in adding request handlers and the like, but component-based +equivalent functionality is planned. + + +Using httpd.js as an XPCOM Component +------------------------------------ + +First, create an XPT file for nsIHttpServer.idl, using the xpidl tool included +in the Mozilla SDK for the environment in which you wish to run httpd.js. See +<http://developer.mozilla.org/en/docs/XPIDL:xpidl> for further details on how to +do this. + +Next, register httpd.js and nsIHttpServer.xpt in your Mozilla application. In +Firefox, these simply need to be added to the /components directory of your XPI. +Other applications may require use of regxpcom or other techniques; consult the +applicable documentation for further details. + +Finally, load httpd.js into the current file, and create an instance of the +server using the following command: + + var server = new nsHttpServer(); + +At this point you'll want to initialize the server, since by default it doesn't +serve many useful paths. For more information on this, see the IDL docs for the +nsIHttpServer interface in nsIHttpServer.idl, particularly for +registerDirectory (useful for mapping the contents of directories onto request +paths), registerPathHandler (for setting a custom handler for a specific path on +the server, such as CGI functionality), and registerFile (for mapping a file to +a specific path). + +Finally, you'll want to start (and later stop) the server. Here's some example +code which does this: + + server.start(8080); // port on which server will operate + + // ...server now runs and serves requests... + + server.stop(); + +This server will only respond to requests on 127.0.0.1:8080 or localhost:8080. +If you want it to respond to requests at different hosts (say via a proxy +mechanism), you must use server.identity.add() or server.identity.setPrimary() +to add it. + + +Using httpd.js as an Inline Script or from xpcshell +--------------------------------------------------- + +Using httpd.js as a script or from xpcshell isn't very different from using it +as a component; the only real difference lies in how you create an instance of +the server. To create an instance, do the following: + + var server = new nsHttpServer(); + +You now can use |server| exactly as you would when |server| was created as an +XPCOM component. Note, however, that doing so will trample over the global +namespace, and global values defined in httpd.js will leak into your script. +This may typically be benign, but since some of the global values defined are +constants (specifically, Cc/Ci/Cr as abbreviations for the classes, interfaces, +and results properties of Components), it's possible this trampling could +break your script. In general you should use httpd.js as an XPCOM component +whenever possible. + + +Known Issues +------------ + +httpd.js makes no effort to time out requests, beyond any the socket itself +might or might not provide. I don't believe it provides any by default, but +I haven't verified this. + +Every incoming request is processed by the corresponding request handler +synchronously. In other words, once the first CRLFCRLF of a request is +received, the entire response is created before any new incoming requests can be +served. I anticipate adding asynchronous handler functionality in bug 396226, +but it may be some time before that happens. + +There is no way to access the body of an incoming request. This problem is +merely a symptom of the previous one, and they will probably both be addressed +at the same time. + + +Other Goodies +------------- + +A special testing function, |server|, is provided for use in xpcshell for quick +testing of the server; see the source code for details on its use. You don't +want to use this in a script, however, because doing so will block until the +server is shut down. It's also a good example of how to use the basic +functionality of httpd.js, if you need one. + +Have fun! diff --git a/netwerk/test/httpserver/TODO b/netwerk/test/httpserver/TODO new file mode 100644 index 0000000000..3a95466117 --- /dev/null +++ b/netwerk/test/httpserver/TODO @@ -0,0 +1,17 @@ +Bugs to fix: +- make content-length generation not rely on .available() returning the entire + size of the body stream's contents -- some sort of wrapper (but how does that + work for the unscriptable method WriteSegments, which is good to support from + a performance standpoint?) + +Ideas for future improvements: +- add API to disable response buffering which, when called, causes errors when + you try to do anything other than write to the body stream (i.e., modify + headers or status line) once you've written anything to it -- useful when + storing the entire response in memory is unfeasible (e.g., you're testing + >4GB download characteristics) +- add an API which performs asynchronous response processing (instead of + nsIHttpRequestHandler.handle, which must construct the response before control + returns; |void asyncHandle(request, response)|) -- useful, and can it be done + in JS? +- other awesomeness? diff --git a/netwerk/test/httpserver/httpd.js b/netwerk/test/httpserver/httpd.js new file mode 100644 index 0000000000..c8cfc997c5 --- /dev/null +++ b/netwerk/test/httpserver/httpd.js @@ -0,0 +1,5646 @@ +/* -*- indent-tabs-mode: nil; js-indent-level: 2 -*- */ +/* vim:set ts=2 sw=2 sts=2 et: */ +/* This Source Code Form is subject to the terms of the Mozilla Public + * License, v. 2.0.
