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”：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”？

=========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);
})
})
}
