javascript - 如何撤销针对 Google Api 的身份验证 token 客户端

Question

我正在尝试使用 Google Api 客户端代码撤销 token 。

我的代码看起来像这样:

$.get("https://accounts.google.com/o/oauth2/revoke?token=" + accessToken, function () {
        window.location.reload();
    }); 

我收到以下错误？

XMLHttpRequest cannot load https://accounts.google.com/o/oauth2/revoke?token=tokenishere Origin http://balblabla.com is not allowed by Access-Control-Allow-Origin.

经过一番研究后，我发现您可以通过在 jquery ajax 请求中指定 dataType: 'jsonp' 选项来绕过 cors 限制。相关信息在这里:https://developers.google.com/+/web/signin/disconnect

$.ajax({
  type: 'GET',
  url: revokeUrl,
  async: false,
  contentType: "application/json",
  dataType: 'jsonp',
  success: function(nullResponse) {
    // Do something now that user is disconnected
    // The response is always undefined.
  },
  error: function(e) {
    // Handle the error
    // console.log(e);
    // You could point users to manually disconnect if unsuccessful
    // https://plus.google.com/apps
  }
});
