尝试使用 JavaScript 从 azure 获取访问令牌时无法加载响应数据

我想为我在 azure 上注册的应用程序获取访问令牌。为此，我编写了一段代码来访问其余 API。


这是我的代码：


<html>

<head>

  <title>Test</title>   

  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>

  <script src="https://secure.aadcdn.microsoftonline-p.com/lib/1.0.12/js/adal.min.js"></script>

  <script src="/static/powerbi.js"></script>

  <script src="https://unpkg.com/axios/dist/axios.min.js"></script>        

  </head>

<body>

  <div id="captionArea">

    <h1>Power BI Embed test</h1>

  </div>

  <div id="embedContainer" style="height:500px">

  </div> 

  <script>

    (function () {


    var reportId = 'xxxxxxxxxx'

    var groupId  = 'xxxxxxxxxx'   //workspace_id

    var datasetId = 'xxxxxxxxxx'

    

    

   var settings = {

  "url": "https://login.microsoftonline.com/common/oauth2/token",

  "method": "POST",

  "crossDomain": true,

  "dataType": 'jsonp',

  "timeout": 0,

  "headers": {

    "Content-Type": "application/x-www-form-urlencoded"

  },

  "data": {

    "client_id": "********",

    "username": "***",

    "password": "***",

    "grant_type": "password",

    "resource": "https://analysis.windows.net/powerbi/api"

  }

};


$.ajax(settings).done(function (response) {

  console.log(response);

}); 

}());

  </script>

</body>

</html>

之后，我得到了回应。在控制台的标题部分下，我得到了状态：200和请求方法：GET，但在我的代码中，请求方法是“POST”，并且在响应部分中，它显示“此请求没有可用的响应数据”：

https://img1.sycdn.imooc.com/657aaf220001b52313640640.jpg

我不知道为什么我没有得到任何响应以及我的请求方法如何从“POST”更改为“GET”？

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </script>&nbsp; &nbsp; </body></html>=========更新======例如我想调用这个api来获取信息 'https://api.powerbi.com/v1.0/myorg/groups' ，所以先添加api权限。下一步是获取此范围的访问令牌。有了这个访问令牌，调用 api 就可以了。

您的数据类型为 JSONP。它只是创建一个元素来获取必须是 GET 请求的数据。您可以通过发出 POST 请求来获取响应，然后使用获得的访问令牌作为嵌入令牌。像下面这样的事情：var getAccessToken = function {  return new Promise(function(resolve, reject) {    var url = 'https://login.microsoftonline.com/common/oauth2/token';    var username = // Username of PowerBI "pro" account - stored in config    var password = // Password of PowerBI "pro" account - stored in config    var clientId = // Applicaton ID of app registered via Azure Active Directory - stored in config    var headers = {      'Content-Type' : 'application/x-www-form-urlencoded'    };    var formData = {      grant_type:'password',      client_id: clientId,      resource:'https://analysis.windows.net/powerbi/api',      scope:'openid',      username:username,      password:password    };    request.post({      url:url,      form:formData,      headers:headers    }, function(err, result, body) {      if(err) return reject(err);      var bodyObj = JSON.parse(body);      resolve(bodyObj.access_token);    })  });}// -------------------------------------------var getEmbedToken = function(accessToken, groupId, reportId) {  return new Promise(function(resolve, reject) {    var url = 'https://api.powerbi.com/v1.0/myorg/groups/' + groupId + '/reports/' + reportId + '/GenerateToken';    var headers = {      'Content-Type' : 'application/x-www-form-urlencoded',      'Authorization' : 'Bearer ' + accessToken    };    var formData = {      "accessLevel": "View"    };    request.post({      url:url,      form:formData,      headers:headers    }, function(err, result, body) {      if(err) return reject(err);      console.log(body)      var bodyObj = JSON.parse(body);      resolve(bodyObj.token);    })  })}
