DELETE方法不工作 [英] DELETE method not working

问题描述

我写了包含删除客户端具有下列方法的WebAPI控制器...

I have written a WebApi controller that contains the following method for deleting a client...

[HttpDelete]
public void DeleteClient(int id) {
  // do stuff here
}

......，我试图通过使用网页...

...and am trying to test it by using the following HTML on a web page...

<form method="DELETE" action="/api/ClientsXml/">
  <table style="padding: 5px">
    <tr>
      <td>ID</td>
      <td><input type="text" size="20" name="id" id="id" /></td>
    </tr>
    <tr>
      <td> </td>
      <td><input type="submit" value="Send" /></td>
    </tr>
  </table>
</form>

不过，DeleteClient方法不会被调用。它贯穿于GetClient方法，而不是请求。

However, the DeleteClient method is never called. It passes the request through to the GetClient method instead.

任何人任何想法，为什么？我已经试过各种变化，但我就是不能让所谓的删除方法。

Anyone any idea why? I've tried all sorts of variations, but I just can't get the delete method called.

推荐答案

@ DimitryS的答案是正确的，但我想我会建立一点就可以了。

@DimitryS's answer is correct, but I thought I'd build on it a little.

HTML表单只允许GET和POST操作。这是 HTML 5规范当前以及在HTML＆LT; 4规格。

HTML forms only allow GET and POST operations. This is current in the HTML 5 spec as well as the HTML < 4 spec.

其他的HTTP方法使用的 XMLHtt prequest 这就是underlies jQuery的Ajax功能。所以一个好的选择是使用jQuery你放，删除和它应该在所有的主流浏览器的工作（在此pretty明确的SO问题的一些讨论：<一href=\"http://stackoverflow.com/questions/165779/are-the-put-delete-head-etc-methods-available-in-most-web-browsers\">Are在大多数Web浏览器提供的PUT，DELETE，HEAD等方法呢？）。

Other HTTP methods are allowed when using XMLHttpRequest which is what underlies jQuery's ajax functionality. So a good option could be to use jQuery for your PUTs, DELETEs, and it should work in all major browsers (some discussion of that in this pretty definitive SO question: Are the PUT, DELETE, HEAD, etc methods available in most web browsers?).

最后，我会说，如果你只是使用的形式来测试您的API，那么为什么不尝试一个浏览器扩展，而不是：
例如

Lastly, I'll say that if you are just using the form to test your API, then why not try a browser extension instead: e.g.

• 邮差铬


• RESTClient实现对Firefox

• POSTMan for chrome
• RESTClient for firefox

有更多的人，但多数让您保存一个测试套件，设置不同的页眉，等等。

There are many more, but most allow you to save a test suite, set different headers, and so forth.
