Power BI API - 如何从 app.powerbi.com 获取报告？

Question

我有一些客户端使用 Power BI App。
有了这个 API，我想将所有报告 (.pbix) 放到我的文件夹中。

我怎样才能得到它们？

Answer 1

您只需在浏览器中打开报告并将其另存为 .pbix 文件即可：

如果您想使用 API 执行此操作，您将需要 Export Report In Group REST API. To use it, you need to acquire an access token and add it to your request header. You can acquire it by calling some of the AcuireToken methods from ADAL。

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
}
