问题描述
用 C# 编码.我正在关注本指南:
Coding in C#. I'm following this guide:
https://azure.microsoft.com/en-us/documentation/articles/resource-group-authenticate-service-principal/#authenticate-service-principal-with-password---powershell%E2%80%8C%E2%80%8B
但它不起作用，而且它不是 Power BI 特定的，所以我不确定如何将它应用到 Power BI API.
But it is not working and it is not Power BI specific so I'm not sure exactly how to apply it to the Power BI API.
在尝试连接到 Power BI 时，我收到了 403 Forbidden 响应.
In my attempt to connect to Power BI I am getting a 403 Forbidden response.
var authenticationContext = new AuthenticationContext("https://login.windows.net/" + Properties.Settings.Default.TenantID);
var credential = new ClientCredential(clientId: Properties.Settings.Default.ClientID, clientSecret: Properties.Settings.Default.ClientSecretKey);
var result = authenticationContext.AcquireToken(resource: "https://management.core.windows.net/", clientCredential: credential);
if (result == null)
{
throw new InvalidOperationException("Failed to obtain the JWT token");
}
string accessToken = result.AccessToken;
string responseContent = string.Empty;
//The resource Uri to the Power BI REST API resource
string datasetsUri = "https://api.powerbi.com/v1.0/myorg/datasets";
//Configure datasets request
System.Net.WebRequest request = System.Net.WebRequest.Create(datasetsUri) as System.Net.HttpWebRequest;
request.Timeout = 20000;
request.Method = "GET";
request.ContentLength = 0;
request.Headers.Add("Authorization", String.Format("Bearer {0}", accessToken));
try
{
//Get datasets response from request.GetResponse()
using (var response = request.GetResponse() as System.Net.HttpWebResponse)
{
//Get reader from response stream
using (var reader = new System.IO.StreamReader(response.GetResponseStream()))
{
responseContent = reader.ReadToEnd();
//Deserialize JSON string
//JavaScriptSerializer class is in System.Web.Script.Serialization
JavaScriptSerializer json = new JavaScriptSerializer();
Datasets datasets = (Datasets)json.Deserialize(responseContent, typeof(Datasets));
resultsTextbox.Text = string.Empty;
//Get each Dataset from
foreach (dataset ds in datasets.value)
{
resultsTextbox.Text += String.Format("{0} {1}
", ds.Id, ds.Name);
}
}
}
}
catch (WebException wex)
{
resultsTextbox.Text = wex.Message;
}
}
推荐答案
尝试更改资源 URI:
Try changing the resource URI:
var result = authenticationContext.AcquireToken(resource: "https://management.core.windows.net/", clientCredential: credential);
到
var result = authenticationContext.AcquireToken(resource: **"https://analysis.windows.net/powerbi/api"**, clientCredential: credential);
您想为 power bi api 获取令牌.
You want to acquire a token for the power bi api.
希望有所帮助.
根据 OP 评论编辑更新答案:
这是你需要做的.
在 Azure AD 中创建一个本机应用程序"并获取该客户端 ID，不会有任何秘密.
In Azure AD create a "Native App" and get that client ID there will be NO Secret.
确保您拥有来自 Nuget Active Directory 身份验证库 2.23.302261847 的最新版本的 ADAL
Make sure you have the latest version of ADAL from Nuget Active Directory Authentication Library 2.23.302261847
您将需要使用此 Acquire Token Overload:
You will need to use this Acquire Token Overload:
authContext.AcquireToken("https://analysis.windows.net/powerbi/api", clientID, new UserCredential(<Username>, <Password>));

ADAL 3.13.7 UserCredentail 不再具有上述定义的构造函数.有一个新的密封类 UserPasswordCredential
ADAL 3.13.7 UserCredentail no longer has a constructor as defined above. There is a new sealed class UserPasswordCredential
public sealed class UserPasswordCredential : UserCredential
哪个构造函数与之前的 UserCredential 对象相匹配
Which has the constructor that matches the former UserCredential object
public UserPasswordCredential(string userName, string password)
您可以通过以下方式获取令牌:
You can acquire the token by doing this:
authContext.AcquireToken("https://analysis.windows.net/powerbi/api", clientID, new UserPasswordCredential(<Username>, <Password>));
