如何添加真实性令牌? [英] How do i add the authenticity token?

问题描述

我最近改用Google关闭了一个新项目.我在将真实性令牌添加到ajax调用的标头中时遇到麻烦.我该怎么办?

I recently switched to Google closure for a new project. I am having trouble adding the authenticity token to the headers in a ajax call. How do i go about it?

我的Ajax代码段(使用goog.net.XhrIo类):

My Ajax snippet (using goog.net.XhrIo class):

var initialHTMLContent = superField[i].getCleanContents();

var data = goog.Uri.QueryData.createFromMap(new goog.structs.Map({
  body: initialHTMLContent
 }));

 goog.net.XhrIo.send('/blogs/create', function(e) {
    var xhr = /** @type {goog.net.XhrIo} */ (e.target);
    alert(xhr.getResponseXml());
 }, 'POST', data.toString(), {
    'Accept' : 'text/xml'
            });

在后端使用滑轨.

推荐答案

在Rails视图(.html.erb文件)中的某个位置，您可以设置js变量，如下所示:

Somewhere in a rails view (.html.erb file) you can set a js variable like this:

window._token = '<%= form_authenticity_token %>';

然后将其添加到您的通话中:

And then append it in your call:

 goog.net.XhrIo.send('/blogs/create?authenticity_token=' + window._token, function(e) {
    var xhr = /** @type {goog.net.XhrIo} */ (e.target);
    alert(xhr.getResponseXml());
 }, 'POST', data.toString(), {
    'Accept' : 'text/xml'
            });
