我尝试使用代表其他用户的服务帐户创建DriveService。
我已从此处{google文档https://developers.google.com/drive/delegation
复制此代码 static DriveService BuildService() {
X509Certificate2 certificate = new X509Certificate2(SERVICE_ACCOUNT_PKCS12_FILE_PATH, "notasecret", X509KeyStorageFlags.Exportable);
var provider = new AssertionFlowClient(GoogleAuthenticationServer.Description, certificate)
{
ServiceAccountId = SERVICE_ACCOUNT_EMAIL,
Scope = DriveService.Scopes.Drive.GetStringValue(),
};
var auth = new OAuth2Authenticator<AssertionFlowClient>(provider, AssertionFlowClient.GetState);
return new DriveService(auth);
}
但是在尝试构建项目时我收到了这个警告:
警告4'Google.Apis.Authentication.OAuth2.DotNetOpenAuth.AssertionFlowClient'已过时:'不再支持AssertionFlowClient,它将在1.7.0-beta中删除。考虑使用新的Google.Apis.Auth NuGet包中的ServiceAccountCredential。'
我也得到了这个错误:
错误11参数1:无法从'Google.Apis.Authentication.OAuth2.OAuth2Authenticator'转换为'Google.Apis.Services.BaseClientService.Initializer'
然后我用Google搜索了ServiceAccountCredential并最终得到了这段代码(源自此页面:https://code.google.com/p/google-api-dotnet-client/wiki/OAuth2#Service_Accounts)
static DriveService BuildService() {
X509Certificate2 certificate = new X509Certificate2(SERVICE_ACCOUNT_PKCS12_FILE_PATH, "notasecret", X509KeyStorageFlags.Exportable);
ServiceAccountCredential credential = new ServiceAccountCredential(
new ServiceAccountCredential.Initializer(SERVICE_ACCOUNT_EMAIL)
{
User = "someone@mydomain.mygbiz.com",
Scopes = new[] { DriveService.Scope.DriveFile }
}.FromCertificate(certificate));
var service = new DriveService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = "Drive API Sample",
});
return service;
}
当我尝试构建此代码时,似乎一切正常,但是当我运行它时,我收到以下错误。
mscorlib.dll中出现'System.Security.Cryptography.CryptographicException'类型的第一次机会异常
其他信息:Detgårinteatt hitta detbegärdaobjektet。 (已翻译:找不到请求的对象)
如果存在此异常的处理程序,则可以安全地继续该程序。
此行发生错误:
X509Certificate2 certificate = new X509Certificate2(SERVICE_ACCOUNT_PKCS12_FILE_PATH, "notasecret", X509KeyStorageFlags.Exportable);
有人有什么想法吗?
2013年10月31日更新 我试过这段代码:
{
Console.WriteLine("Drive API - Service Account");
Console.WriteLine("==========================");
String serviceAccountEmail = "<some email>@developer.gserviceaccount.com";
var certificate = new X509Certificate2(@"key.p12", "notasecret", X509KeyStorageFlags.Exportable);
ServiceAccountCredential credential = new ServiceAccountCredential(
new ServiceAccountCredential.Initializer(serviceAccountEmail)
{
User = "<someuser>@<mydomain>.mygbiz.com",
Scopes = new[] { DriveService.Scope.Drive }
}.FromCertificate(certificate));
// Create the service.
var service = new DriveService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = "DrvMgr",
});
Console.WriteLine("Executing listing");
FileList UserFiles = service.Files.List().Execute();
我收到此错误消息:
Google.Apis.dll中发生未处理的“Google.Apis.Auth.OAuth2.Responses.TokenResponseException”类型异常
其他信息:错误:“access_denied”,描述:“”,Uri:“”
答案 0 :(得分:0)
看起来你的p12文件的路径不正确。有关可行的解决方案,请参阅Plus.ServiceAccount示例。
我认为在此示例中,key.p12作为内容文件添加到项目中,该文件始终复制到输出目录。然后从代码中提到“key.p12”文件路径将导致从输出文件夹中获取此文件。
