Delete post with Blogger API

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":开发者_高级运维 "*"
        },
        onSuccess: this.deletePostRequestSuccess.bind(this),
        onFailure: this.deletePostRequestFailure.bind(this)
    });
},

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.

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.

From what I can tell, your issue with the HTTP methods is not webOS, but in Prototype according to the source.

I would suggest creating a subclass:

<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);
}


});
</script>

That way you can use method: 'DELETE'
