我正尝试通过其Javascript API实现 Google Analytics(分析)图,例如其网站link上的示例。
但是每次我尝试执行 gapi.analytics.googleCharts.DataChart
时,我都会不断收到 “ 401无效凭证”我使用以下代码获取访问令牌服务器端(C#),其中包含为服务帐户生成的JSON数据
var cred = new ServiceAccountCredential(
new ServiceAccountCredential.Initializer(clientId)
{
Scopes = new[] { AnalyticsReportingService.Scope.AnalyticsReadonly },
User = clientEmail,
ProjectId = "projectID"
}.FromPrivateKey(privateKey));
var token = cred.GetAccessTokenForRequestAsync(authURI);
token.Wait();
var result = token.Result;
return result;
或(使用完整的json字符串,另请参见注释)
GoogleCredential cred;
var gCred = GoogleCredential.FromJson(json).UnderlyingCredential as
ServiceAccountCredential;
var token = gCred.GetAccessTokenForRequestAsync("https://accounts.google.com/o/oauth2/auth");
return token.Result;
在客户端
gapi.analytics.auth.authorize({
'serverAuth': {
'access_token': '{{ ACCESS_TOKEN_FROM_SERVICE_ACCOUNT }}'
}
});
使用并使用 gapi.analytics.auth.isAuthorized()会使用任何服务器端函数返回true,但在尝试调用时会失败
var dataChart1 = new gapi.analytics.googleCharts.DataChart(queryJson);
dataChart1.execute();
返回401“无效凭据”,服务器端查询返回的值很好,所以我认为用户权限不是问题
注意:使用与第二个代码相同的代码(使用json字符串生成凭据而不将其转换为ServiceAccountCredential),我可以从API服务器端获取数据
cred = gCred.CreateScoped(scopes);
using (var reportingService = new AnalyticsReportingService(new BaseClientService.Initializer
{
HttpClientInitializer = cred
}))
...
var getReportsRequest = new GetReportsRequest
{
ReportRequests = new List<ReportRequest> { reportRequest }
};
var batchRequest = reportingService.Reports.BatchGet(getReportsRequest);
var response = batchRequest.Execute(); //This returns a response object with all the data I need
答案 0 :(得分:0)
如果有人遇到相同的问题:
您需要使用 GoogleCredential.GetApplicationDefault() 创建凭据对象,对于Google Analytics(分析),您应该获得类似的信息
var credential = GoogleCredential.GetApplicationDefault().CreateScoped(AnalyticsReportingService.Scope.AnalyticsReadonly);
这将从Windows上的环境变量获取json文件,因此您需要将 GOOGLE_APPLICATION_CREDENTIALS 设置为json的路径作为系统变量。
初始化服务并设置服务变量
using (var reportingService = new AnalyticsReportingService(new BaseClientService.Initializer { HttpClientInitializer = credential }))
{
var serviceCredential = cred.UnderlyingCredential as ServiceAccountCredential;
}
