来自服务器的 Power BI 嵌入错误 403 禁止错误

Question

我正在遵循 Power BI 社区 here 中提到的步骤，并在 Postman 中对其进行测试，并完成了前 4 个步骤。但是在 Microsoft Power BI Embedded Playground 中测试嵌入代码时，我不断收到以下错误：

{
  "message": "LoadReportFailed",
  "detailedMessage": "Fail to initialize - Could not resolve cluster",
  "errorCode": "403",
  "level": 6,
  "technicalDetails": {
    "requestId": "57679585-022b-4871-ae6d-bb722d4a07cc"
  }
}

另外，当尝试替代方案时，在 STEP 5 中提供的 HTML 设置，我再次收到 403 错误说明：“GET https://wabi-india-west-redirect.analysis.windows.net/powerbi/globalservice/v201606/clusterdetails 403 (Forbidden)”

请帮忙。一个多星期以来，我一直在努力让这个东西工作。

事实证明，尽管我有工作区 ID、客户端 ID、报告 ID，并且虽然我对 API 进行了正确调用，但第五步中的错误是因为我是我的报告所在的工作区的成员。

要使 API 正常工作，您需要成为尝试从中获取报告的工作区的管理员

我最终使用以下步骤解决了这个问题。

要将 Power BI 报告嵌入前端（角度/JS），您必须生成 2 个不同的令牌（仅适用于应用程序场景）。

1. 使用主帐户详细信息/服务主体帐户的访问令牌 （用于连接power BI服务器）
2. 嵌入令牌（可以使用访问令牌和 .NET Power BI rest API 生成）。

第 1 步：访问令牌生成

PBIClientId": "xxxxxx-xxx-xxxx-xxxx-xxxxxxxxx",
    "PBIClientSecret": "<client secret>",
    "PBIApiUrl": "https://api.powerbi.com/",
    "ResourceUrl": "https://analysis.windows.net/powerbi/api",
    "AuthorityUrl": "https://login.windows.net/common/",
    "TenantId": "<TenantId>",

private async Task<string> GeneratePowerBIAccessToken()
    {
        var tenantSpecificURL = authorityUrl.Replace("common", tenantId);
        var authenticationContext = new AuthenticationContext(tenantSpecificURL);

        // Authentication using app credentials
        var credential = new ClientCredential(clientId, clientSecret);
        AuthenticationResult authenticationResult = await authenticationContext.AcquireTokenAsync(resourceUrl, credential);
        return authenticationResult.AccessToken;
    }

第 2 步：获取 Power BI 报表嵌入 URL

传递您在第 1 步中生成的访问令牌、groupId 和您从 Power BI 门户 url 获得的 reportId。

 private async Task<EmbedModel> GetEmbedReportModel(string groupId, string reportId, string accessToken)
    {
        string restUrl = "https://api.powerbi.com/v1.0/myorg/groups/" + groupId+"/reports";

        // add JSON to HttpContent object and configure content type
        var method = new HttpMethod("GET");
        var request = new HttpRequestMessage(method, restUrl);

        using (HttpClient client = new HttpClient())
        {
            client.DefaultRequestHeaders.Add("Accept", "application/json");
            client.DefaultRequestHeaders.Add("Authorization", "Bearer " + accessToken);

            // send POST request to Power BI service 
            var jsonResult = await client.SendAsync(request).Result.Content.ReadAsStringAsync();
            var reportObject = JsonConvert.DeserializeObject<ReportObjects>(jsonResult);
            var report = reportObject.value.Where(r => r.id == reportId).FirstOrDefault();
            return new EmbedModel { Id = report.id, EmbedUrl = report.embedUrl, Name = report.name };
        }
    }

the response you will get here is 
    {
  "value": [
    {
      "datasetId": "xxxxxx-abcasdasd-dasda-4weas",
      "id": "3asder78-asds-4d73-1232-5345dfsdfs",
      "name": "SalesMarketing",
      "webUrl": "https://app.powerbi.com/groups/xxx-xxxxx-xxx-xxxxxx-xxxxx/reports/xxxxxx-xxxx-xxx-xxxx-xxxxxxxx",
      "embedUrl": "https://app.powerbi.com/reportEmbed?reportId=xxxxxx-xxxx-xxxx-xxxx-xxxxxx&groupId=aadasda21-xxcx-xx-xx-xxxxxx"
    }
  ]
}

第 3 步：调用生成嵌入令牌 API

 private async  Task<EmbedToken> GenerateEmbedToken(string groupId, string reportId,string accessToken)
    {
        string apiURL = "https://api.powerbi.com/v1.0/myorg/groups/"+ groupId + "/reports/"+ reportId +"/GenerateToken";
        string requestBody = @"{ ""accessLevel"": ""View""}";
        HttpContent postRequestBody = new StringContent(requestBody);
        postRequestBody.Headers.ContentType = new MediaTypeWithQualityHeaderValue("application/json");

        // prepare PATCH request
        var method = new HttpMethod("POST");
        var request = new HttpRequestMessage(method, apiURL);
        request.Content = postRequestBody;

        using (HttpClient client = new HttpClient())
        {
            client.DefaultRequestHeaders.Add("Accept", "application/json");
            client.DefaultRequestHeaders.Add("Authorization", "Bearer " + accessToken);

            // send POST request to Power BI service 
            var jsonResult = await client.SendAsync(request).Result.Content.ReadAsStringAsync();
            EmbedToken embedToken = JsonConvert.DeserializeObject<EmbedToken>(jsonResult);

            return embedToken;
        }
    }

第 4 步：在前端应用中使用嵌入令牌和嵌入 url

<html>
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.js"></script>
  <script src="powerbi.min.js" type="text/javascript"> </script>
  <script type="text/javascript">
           window.onload = function () {
           var models = window['powerbi-client'].models;
          var embedConfiguration = {
               type: 'report',
			   id:'537887ee-7c7c-43c6-850b-9293f60aa3f3',
               accessToken: 'H4sIAAAAAAAEAB3Tt66EV.....phVP_a_5F15fA_FCBQAA',
               embedUrl: 'https://app.powerbi.com/reportEmbed?reportId=2376660ee-1c2c-16c6-980b-923260aa3f3&amp;groupId=2adeaaa-xxxx-xxxx-xxxx-8d13b04c6e0e&amp;w=2&amp;config=eyJjbHVzdGVyV.....',
               permissions: models.Permissions.All,
               tokenType: models.TokenType.Embed,
               viewMode:models.ViewMode.View,
           };

           var $reportContainer = $('#dashboardContainer');
           var report = powerbi.embed($reportContainer.get(0), embedConfiguration);

       }
   </script>
   <div id="dashboardContainer"></div>
</html>

在运行之前更改所有值。

请确保您在授权标头中发送正确的令牌。确保使用“Bearer”作为授权标头。

另外，请确保您的用户拥有所有必需的权限。
