我发现我的AJAX DELETE请求不发送数据参数到控制器，当我通过水豚，WebKit的执行。然而，数据参数也被发送（和测试通过），当我运行测试套件通过使用硒。我的code如下所示：

I'm finding that my ajax DELETE requests are not sending data parameters to the controller when I execute them through capybara-webkit. However, the data parameters do get sent (and the test passes) when I run the test suite by using selenium. My code looks like the following:

$(document).on 'click', 'a.delete_contact', ->
  if confirm "Are you sure you want to delete this contact?"
    id = $('a.delete_contact').data('id')
    name = $('a.delete_contact').data('name')
    $.ajax '/contacts',
      type: 'DELETE'
      dataType: 'html'
      data: {'id' : id}
      success: ->
        $("li[data-cid='#{id}']").remove()
        removeInitial(_.last(name.split(" "))[0])
        show_notice("Contact successfully destroyed.", 'notice')
        window.contactSelection.pop()        
        refreshSelectionView()
  return false

任何想法，为什么这种失败在水豚，WebKit的？

Any ideas why this is failing in capybara-webkit?

推荐答案

显然QtWebKit的不支持的实体机构，DELETE请求。

Apparently QtWebKit does not support an entity body with DELETE requests.

一个水豚，WebKit的开发者推荐使用这种解决方法：...... [发送]有一个参数标识请求为删除此机制是Rails的工作，跨浏览器的周围类似的问题POST请求

A capybara-webkit developer recommended this work-around: "[Send] a POST request with a parameter identifying the request as a DELETE. This mechanism is used by Rails to work around similar issues across browsers."
