Can you make a HTTP PATCH request from Javascript?
提问by NSA
I am working with an API that requires me to make an HTTP PATCH request as part of the URI, is this possible to do from Javascript, my research is showing that I can only do POST, GET, DELETE, and PUT. Is PATCH allowed?

Thank you,

I'm not sure what you exactly mean by a "PATCH" request, but it seems to be possible (at least in Firefox 6 and Chromium 12). According to the Mozilla source code, there is only a limitation of TRACEand TRACKrequests.
我不确定“PATCH”请求的确切含义，但它似乎是可能的（至少在 Firefox 6 和 Chromium 12 中）。根据Mozilla 源代码，只有TRACE和TRACKrequests的限制。
A quick testcase:
一个快速的测试用例：
<!-- test.html -->
<script>
var x=new XMLHttpRequest();
x.open("patch", "/");
x.send(null);
</script>
Any webserver can be used, but I choose for Python's SimpleHTTPServer module.
可以使用任何网络服务器，但我选择 Python 的 SimpleHTTPServer 模块。
$ ls
test.html
$ python -m SimpleHTTPServer
localhost - - [21/Sep/2011 17:32:11] "GET /test.html HTTP/1.1" 200 -
localhost - - [21/Sep/2011 17:32:11] code 501, message Unsupported method ('patch')
localhost - - [21/Sep/2011 17:32:11] "patch / HTTP/1.1" 501 -
So, as long as the server supports the method, the request get's passed.
因此，只要服务器支持该方法，请求 get 就会通过。

As of some research the PATCHmethod seems to be new (march 2010 http://tools.ietf.org/html/rfc5789) so if you try to define PATCHon an XMLHttpRequest it may work, but only on very latest revisions of modern browsers. Don't have a supported browser list found, yet.
根据一些研究，该PATCH方法似乎是新的（2010 年 3 月http://tools.ietf.org/html/rfc5789），因此如果您尝试PATCH在 XMLHttpRequest上定义它可能会起作用，但仅适用于现代浏览器的最新版本。还没有找到受支持的浏览器列表。
