我制作了一个程序,使用谷歌驱动器API从谷歌驱动器上的文件中读取数据.
第一次运行应用程序时,它会打开一个Web浏览器,要求使用google驱动器帐户登录.
我想为应用程序提供用户名和密码,以便自动获取凭据,以便用户无需知道我的google云端硬盘帐户的用户名和密码.
这是vb.net中的代码:
Dim credential As UserCredential
Using stream = New FileStream("client_secret.json", FileMode.Open, FileAccess.Read)
Dim credPath As String = System.Environment.GetFolderPath(
System.Environment.SpecialFolder.Personal)
credPath = Path.Combine(credPath, ".credentials/drive-dotnet-quickstart.json")
credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
GoogleClientSecrets.Load(stream).Secrets,
Scopes,
"user",
CancellationToken.None,
New FileDataStore(credPath, True)).Result
'Console.WriteLine("Credential file saved to: " + credPath)
End Using
//I want to provide the username and password in the app so that it doesn't open a web browser asking for them
' Create Drive API service.
Dim initializer = New BaseClientService.Initializer
initializer.HttpClientInitializer = credential
initializer.ApplicationName = ApplicationName
Dim service = New DriveService(initializer)
' Define parameters of request.
Dim listRequest As FilesResource.ListRequest = service.Files.List()
listRequest.PageSize = 10
listRequest.Fields = "nextPageToken, files(id, name)"
' List files.
Dim files As IList(Of Google.Apis.Drive.v3.Data.File) = listRequest.Execute().Files
这是c#中的代码:
UserCredential credential;
using (var stream =
new FileStream("client_secret.json", FileMode.Open, FileAccess.Read))
{
string credPath = System.Environment.GetFolderPath(
System.Environment.SpecialFolder.Personal);
credPath = Path.Combine(credPath, ".credentials/drive-dotnet-quickstart.json");
credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
GoogleClientSecrets.Load(stream).Secrets,
Scopes,
"user",
CancellationToken.None,
new FileDataStore(credPath, true)).Result;
//Console.WriteLine("Credential file saved to: " + credPath);
}
//I want to provide the username and password in the app so that it doesn't open a web browser asking for them
// Create Drive API service.
var service = new DriveService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = ApplicationName,
});
// Define parameters of request.
FilesResource.ListRequest listRequest = service.Files.List();
listRequest.PageSize = 10;
listRequest.Fields = "nextPageToken, files(id, name)";
// List files.
IList files = listRequest.Execute()
.Files;

不幸的是你无法嵌入这样的登录名和密码.我还有其他选择.
听起来您正试图允许用户访问您的个人Google云端硬盘帐户.在这种情况下,您应该使用服务帐户和Not Oauth2.Oauth2要求用户以网页的形式进行交互,以授予应用程序访问用户自己的谷歌驱动器帐户的权限.虽然服务帐户是由开发人员在后台预先授权的.
将服务帐户视为虚拟用户.您可以通过使用服务帐户电子邮件地址共享Google云端硬盘中的文件夹,授予其访问您的Google云端硬盘帐户的权限.
以下是使用服务帐户进行身份验证的示例代码.
////// Authenticating to Google using a Service account /// Documentation: https://developers.google.com/accounts/docs/OAuth2#serviceaccount /// /// From Google Developer console https://console.developers.google.com /// Location of the .p12 or Json Service account key file downloaded from Google Developer console https://console.developers.google.com ///AnalyticsService used to make requests against the Analytics API public static DriveService AuthenticateServiceAccount(string serviceAccountEmail, string serviceAccountCredentialFilePath) { try { if (string.IsNullOrEmpty(serviceAccountCredentialFilePath)) throw new Exception("Path to the service account credentials file is required."); if (!File.Exists(serviceAccountCredentialFilePath)) throw new Exception("The service account credentials file does not exist at: " + serviceAccountCredentialFilePath); if (string.IsNullOrEmpty(serviceAccountEmail)) throw new Exception("ServiceAccountEmail is required."); // These are the scopes of permissions you need. It is best to request only what you need and not all of them string[] scopes = new string[] { AnalyticsReportingService.Scope.Analytics }; // View your Google Analytics data // For Json file if (Path.GetExtension(serviceAccountCredentialFilePath).ToLower() == ".json") { GoogleCredential credential; using (var stream = new FileStream(serviceAccountCredentialFilePath, FileMode.Open, FileAccess.Read)) { credential = GoogleCredential.FromStream(stream) .CreateScoped(scopes); } // Create the Analytics service. return new DriveService(new BaseClientService.Initializer() { HttpClientInitializer = credential, ApplicationName = "Drive Service account Authentication Sample", }); } else if (Path.GetExtension(serviceAccountCredentialFilePath).ToLower() == ".p12") { // If its a P12 file var certificate = new X509Certificate2(serviceAccountCredentialFilePath, "notasecret", X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.Exportable); var credential = new ServiceAccountCredential(new ServiceAccountCredential.Initializer(serviceAccountEmail) { Scopes = scopes }.FromCertificate(certificate)); // Create the Drive service. return new DriveService(new BaseClientService.Initializer() { HttpClientInitializer = credential, ApplicationName = "Drive Authentication Sample", }); } else { throw new Exception("Unsupported Service accounts credentials."); } } catch (Exception ex) { Console.WriteLine("Create service account DriveService failed" + ex.Message); throw new Exception("CreateServiceAccountDriveFailed", ex); } } }
用法:
var service = AuthenticateServiceAccount("1046123799103-6v9cj8jbub068jgmss54m9gkuk4q2qu8@developer.gserviceaccount.com", @"C:\Users\linda_l\Documents\Diamto Test Everything Project\ServiceAccountTest\Diamto Test Everything Project-145ed16d5d47.json");
