使用Blogger API删除帖子 [英] Delete post with Blogger API

问题描述

我正在使用Blogger协议API，但无法删除帖子.我正在使用WebOS设备，因此无法直接发送DELETE；相反，我使用Google的解决方法来使用POST:

I'm using the Blogger Protocol API and I'm having trouble deleting posts. I'm working on a webOS device and so I can't send DELETE directly; instead I use Google's workaround to use 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)
    });
},

这似乎可行，即deletePostRequestSuccess在此过程之后被调用，并且所有标题和响应文本看起来都像我在删除帖子时应该使用的，但现实情况是帖子仍保留在提要中.我尝试添加"If-Match"标头，以确保它不是阻止我的GData条件删除(即使此时我没有更改帖子中的任何内容)，但这似乎无济于事.

This seems to work, i.e. deletePostRequestSuccess is called after this processes and all the headers and response text look like I think they should when deleting a post, but the reality is that the post remains in the feed. I tried adding the "If-Match" header to make sure it wasn't the GData conditional delete holding me up (even though I haven't changed anything in the post at this time), but that doesn't seem to help.

关于如何进行这项工作的任何想法?我想坚持使用Protocol，因为它是WebOS上的本机，而jQuery等不是本机上的.

Any ideas on how to make this work? I'd like to stick with Protocol since it's native on webOS, whereas jQuery, etc. is not.

推荐答案

据我所知，您的HTTP方法问题不是webOS，而是Prototype

From what I can tell, your issue with the HTTP methods is not webOS, but in 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);

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

/* 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);
}

})； </script>

}); </script>

这样，您就可以使用method: 'DELETE'
