Question

我正在使用Blogger协议API，但我无法删除帖子。我正在使用webOS设备，因此我无法直接发送DELETE;相反，我使用Google的解决方法来使用POST：

deletePostList: function(event)
{
    var deletePostID = event.item.id.split('.').pop().split('-').pop();
    var deleteRequest = new Ajax.Request("http://www.blogger.com/feeds/" + activeBlogID + "/posts/default/" + deletePostID,
    {
        method: 'post',
        requestHeaders:
        {
            Authorization: 'GoogleLogin auth=' + authCode,
            "X-HTTP-Method-Override": "DELETE",
            "If-Match": "*"
        },
        onSuccess: this.deletePostRequestSuccess.bind(this),
        onFailure: this.deletePostRequestFailure.bind(this)
    });
},

这似乎有效，即在此过程之后调用deletePostRequestSuccess，并且所有标题和响应文本看起来像我认为在删除帖子时应该这样，但实际情况是帖子仍保留在Feed中。我尝试添加“If-Match”标题以确保它不是GData条件删除阻止我（即使我此时没有更改帖子中的任何内容），但这似乎没有帮助。

有关如何使这项工作的任何想法？我想坚持使用Protocol，因为它在webOS上是原生的，而jQuery等则不是。

据我所知，您使用HTTP方法的问题不是webOS，而是Prototype according to the source。

我建议创建一个子类：


<script type="text/javascript">
var MyAjaxRequest = Class.create(Ajax.Request, {

request: function(url) {
    this.url = url;
    this.method = this.options.method;
    var params = Object.isString(this.options.parameters) ?
          this.options.parameters :
          Object.toQueryString(this.options.parameters);

/* comment out this stuff that prevents you from using the DELETE method

if (!['get', 'post'].include(this.method)) {
  // simulate other verbs over post
  params += (params ? '&' : '') + "_method=" + this.method;
  this.method = 'post';
}


*/

if (params && this.method === 'get') {
  // when GET, append parameters to URL
  this.url += (this.url.include('?') ? '&' : '?') + params;
}

this.parameters = params.toQueryParams();

try {
  var response = new Ajax.Response(this);
  if (this.options.onCreate) this.options.onCreate(response);
  Ajax.Responders.dispatch('onCreate', this, response);

  this.transport.open(this.method.toUpperCase(), this.url,
    this.options.asynchronous);

  if (this.options.asynchronous) this.respondToReadyState.bind(this).defer(1);

  this.transport.onreadystatechange = this.onStateChange.bind(this);
  this.setRequestHeaders();

  this.body = this.method == 'post' ? (this.options.postBody || params) : null;
  this.transport.send(this.body);

  /* Force Firefox to handle ready state 4 for synchronous requests */
  if (!this.options.asynchronous && this.transport.overrideMimeType)
    this.onStateChange();

}
catch (e) {
  this.dispatchException(e);
}


if (!['get', 'post'].include(this.method)) {
  // simulate other verbs over post
  params += (params ? '&' : '') + "_method=" + this.method;
  this.method = 'post';
}

这样你可以使用if (params && this.method === 'get') { // when GET, append parameters to URL this.url += (this.url.include('?') ? '&' : '?') + params; } this.parameters = params.toQueryParams(); try { var response = new Ajax.Response(this); if (this.options.onCreate) this.options.onCreate(response); Ajax.Responders.dispatch('onCreate', this, response); this.transport.open(this.method.toUpperCase(), this.url, this.options.asynchronous); if (this.options.asynchronous) this.respondToReadyState.bind(this).defer(1); this.transport.onreadystatechange = this.onStateChange.bind(this); this.setRequestHeaders(); this.body = this.method == 'post' ? (this.options.postBody || params) : null; this.transport.send(this.body); /* Force Firefox to handle ready state 4 for synchronous requests */ if (!this.options.asynchronous && this.transport.overrideMimeType) this.onStateChange(); } catch (e) { this.dispatchException(e); }
