Question

我不是c＃的专家，这是我的第一个使用google api和服务帐户的项目。我遇到了一个我不知道如何解决的问题。此代码适用于2台计算机，但不在3台计算机上。

第3台计算机在尝试运行时出现错误无效的原型错误选中代码Documentation Google API - Service account

可能是什么问题？

使用过的代码：

string[] scopes = new string[] { AnalyticsService.Scope.AnalyticsReadonly };
var keyFilePath = System.AppDomain.CurrentDomain.BaseDirectory + "www.site.nl-012345678.p12";
string serviceAccountEmail = "name@api-project-000000000000.iam.gserviceaccount.com";
string applicationName = "www.applicationname.nl";
string password = "notasecret";

//loading the Key file<br>
var certificate = new X509Certificate2(keyFilePath, password, X509KeyStorageFlags.Exportable);
var credential = new ServiceAccountCredential(
new ServiceAccountCredential.Initializer(serviceAccountEmail)
{
    Scopes = scopes
}.FromCertificate(certificate));

// setup the service
var service = new AnalyticsService(new BaseClientService.Initializer()
{
    HttpClientInitializer = credential,
    ApplicationName = applicationName
});

编辑（添加了堆栈跟踪）：

Answer 1

我有同样的问题（我使用的是P12文件）。代码在我的桌面上运行，但是一旦我将其部署到Azure，就会因“无效的提供类型”错误而失败。

我缺少的是：X509KeyStorageFlags.MachineKeySet

像这样：

string sKeyFile = System.Web.Hosting.HostingEnvironment.MapPath("/Keys/" + ServiceAccountKey);
if (!System.IO.File.Exists(sKeyFile))
{
    throw new Exception("Key file can't be found! " + sKeyFile);
}

var certificate = new X509Certificate2(sKeyFile, "notasecret", 
                   X509KeyStorageFlags.Exportable | X509KeyStorageFlags.MachineKeySet);

Answer 2

这可能是该计算机上证书的加密问题。如果我可以重新创建它，我可能会玩它只是为了看看是什么导致它，但因为我不能在这里找到一个“可能”的方式。

转到Google开发者控制台。下载服务帐户.Json文件而不是服务帐户.p12文件。然后使用此代码

 GoogleCredential credential;
 using (var stream = new FileStream(serviceAccountCredentialFilePath, FileMode.Open, FileAccess.Read))
       {
       credential = GoogleCredential.FromStream(stream)
                    .CreateScoped(scopes);
       }

 // Create the service.
 var service = new AnalyticsService(new BaseClientService.Initializer()
    {
    HttpClientInitializer = credential,
    ApplicationName = "Google Authentication Sample",
    });

如果你真的想知道可能导致它的原因，我会看看是否可以找人来ping。
