Yammer 授权错误

Question

我在尝试运行此代码时收到以下错误：

        function getCurrentUser() {
        yam.platform.request({
            // yam.request({
            url: "users/current.json", //this is one of many REST endpoints that are available
            method: "GET",

            data: {},
            success: function (user) { //print message response information to the console
                console.log("User request was successful.");
                console.dir(user);
                toggleLoginStatus(true);
                $('#authResult').html('User Result:<br/>');
                for (var field in user) {
                    $('#authResult').append(' ' + field + ': ' +
                        escape(user[field]) + '<br/>');
                }

            },
            error: function (user) {
                console.error("There was an error with the request.");
            }
        });

    }  

Error: XMLHttpRequest cannot load https://api.yammer.com/api/v1/users/current.json?_=1407933095976. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://brillioonline.sharepoint.com' is therefore not allowed access.

我正在尝试使用以下代码来解决错误，但不知道这里是什么令牌：

$.ajax(
'https://app.asana.com/api/1.0/users/me',
{
type: 'GET',
dataType: 'json',
beforeSend: function (xhr) {
  xhr.setRequestHeader("Authorization", "Bearer $token")
},
complete: function (resp) {
  console.log(resp);
},
error: function (jqXHR,  textStatus,  errorThrown) {
  console.log(textStatus);
}
}
 );

请帮帮我，我是初学者

Answer 1

首先，您不需要使用 Ajax 或手动设置标题。 Yammer js sdk 为您完成。但是如果你真的想使用Ajax，你可以从getLoginStatus的响应中获取token（见下文）

要在没有 Ajax 的情况下获取当前用户，请确保您已经登录。这是一个示例：

function login() {
    yam.platform.getLoginStatus(function (response) {
          if (response.authResponse) { //if already logged in
              alert("token=" + response.access_token.token);
          } else {
              yam.platform.login(function (response) {
                  if (response.authResponse) {
                      alert("token=" + response.access_token.token);
                  }
              });
          }
    });
}

2。成功登录后，运行您的请求。如果仍然不起作用，请在 getLoginStatus 块内运行请求：

yam.platform.getLoginStatus(function (response) {
      if (response.authResponse) {
          //RUN YOUR REQUEST HERE.
      } else {
          alert("something went wrong");
      }
});
