你能从Javascript发出HTTP PATCH请求吗？

问题描述

我正在使用一个API，要求我作为URI的一部分发出HTTP PATCH请求，这是可以通过Javascript做的，我的研究显示我只能执行POST，GET，DELETE和PUT。是否允许PATCH？

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?

谢谢，

推荐答案

我是不确定你的PATCH请求究竟是什么意思，但似乎有可能（至少在Firefox 6和Chromium 12中）。根据，只有 TRACE 和 TRACK 请求的限制。

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 TRACE and TRACK requests.

快速测试用例：

<!-- test.html -->
<script>
var x=new XMLHttpRequest();
x.open("patch", "/");
x.send(null);
</script>

可以使用任何网络服务器，但我选择Python的SimpleHTTPServer模块。

Any webserver can be used, but I choose for Python's SimpleHTTPServer module.

$ 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 -

因此，只要服务器支持该方法，就会传递请求。

So, as long as the server supports the method, the request get's passed.
