  您只需在浏览器中打开报告并将其另存为.pbix文件：

  如果您想使用API执行此操作，则需要Export Report In Group REST API . 要使用它，您需要获取访问令牌并将其添加到您的请求标头中 . 您可以通过调用ADAL中的一些AcuireToken方法来获取它 .

  您可以使用这样的代码（请注意示例中没有错误检查）：

  string clientId = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"; // Obtain at https://dev.powerbi.com/apps
  string redirectUri = "https://login.live.com/oauth20_desktop.srf";
  string resourceUri = "https://analysis.windows.net/powerbi/api";
  string authorityUri = "https://login.windows.net/common/oauth2/authorize";
  
  AuthenticationContext authContext = new AuthenticationContext(authorityUri, new TokenCache()); // PM> Install-Package Microsoft.IdentityModel.Clients.ActiveDirectory
  
  var authenticationResult = await authContext.AcquireTokenAsync(resourceUri, clientId, new Uri(redirectUri), new PlatformParameters(PromptBehavior.Auto));
  var accessToken = authenticationResult.AccessToken);
  
  string powerBIApiUrl = "https://api.powerbi.com/v1.0/myorg/groups/{groupId}/reports/{reportKey}/Export"; // Replace groupId and reportKey with actual values
  
  var request = WebRequest.Create(powerBIApiUrl) as HttpWebRequest;
  request.KeepAlive = true;
  request.Method = "GET";
  request.ContentLength = 0;
  request.ContentType = "application/json";
  request.Headers.Add("Authorization", $"Bearer {accessToken}");
  
  using (HttpWebResponse httpResponse = request.GetResponse() as System.Net.HttpWebResponse)
  {
      //Read httpResponse.GetResponseStream() to get the .pbix file
  }
