尝试使用Windows Forms代码在Google Apps域中创建用户 [英] Trying to Creating users in Google Apps domain in Windows Forms code

问题描述

我正在尝试从Windows窗体应用程序创建用户.

I'm trying to create a user from a windows forms application.

我已经设法在consoleapp中做到了，但是我想要在适当的Windows app中做到这一点. :)

I've managed to do it in a consoleapp, but I want it in a proper windows app. :)

要获得正确的身份验证，'我试图弄清楚AssertionFlowClient的工作方式，但不会正确进行.

To get the authentication right' I've tried to figure out how the AssertionFlowClient is working, but it won't come out right.

这是关键代码:

private void CreateUserBtn_Click(object sender, EventArgs e)
    {
        var provider = new AssertionFlowClient(GoogleAuthenticationServer.Description, new X509Certificate2(@"C:\key.p12", "notasecret", X509KeyStorageFlags.Exportable))
        {
            ServiceAccountId = "[e-mail]",
            Scope = DirectoryService.Scopes.AdminDirectoryUser.GetStringValue(),
            ServiceAccountUser = "[e-mail]",
        };

        var auth = new OAuth2Authenticator<AssertionFlowClient>(provider, AssertionFlowClient.GetState);

        DirectoryService m_serviceUser = new DirectoryService(new BaseClientService.Initializer()
        {
            Authenticator = auth,
        });
        User newuserbody = new User();
        UserName newusername = new UserName();
        newuserbody.PrimaryEmail = UserNameTextBox.Text + "@" + DomainTextBox.Text;
        newusername.GivenName = GivenNameTextBox.Text;
        newusername.FamilyName = FamilyNameTextBox.Text;
        newuserbody.Name = newusername;
        newuserbody.Password = PasswordTextBox.Text;

        m_serviceUser.Users.Insert(newuserbody).Execute();
    }

这是错误消息:

在Google.Apis.dll中发生了类型为'DotNetOpenAuth.Messaging.ProtocolException'的未处理异常

An unhandled exception of type 'DotNetOpenAuth.Messaging.ProtocolException' occurred in Google.Apis.dll

其他信息:发送直接消息或获取响应时发生错误.

Additional information: Error occurred while sending a direct message or getting the response.

再次添加了som Debug输出:

推荐答案

我设法通过主要来自google-api-samples/Tasks.WinForms.NoteMgr的modyfin代码解决了这一问题；这是我的操作方式:

I managed to solve this, primarily by modyfin code from the google-api-samples/Tasks.WinForms.NoteMgr; Here's how I've done it:

 public static DirectoryService Service { get; private set; }

    private static IAuthenticator CreateAuthenticator()
    {
        var provider = new NativeApplicationClient(GoogleAuthenticationServer.Description);
        provider.ClientIdentifier = <myClientId>;
        provider.ClientSecret = <myClientSecret>";
        return new OAuth2Authenticator<NativeApplicationClient>(provider, GetAuthentication);
    }

    private static IAuthorizationState GetAuthentication(NativeApplicationClient client)
    {
        // You should use a more secure way of storing the key here as
        // .NET applications can be disassembled using a reflection tool.
        const string STORAGE = "bergstedts.directoryservice";
        const string KEY = "y},drdzf11x9;87";
        string scope = DirectoryService.Scopes.AdminDirectoryUser.GetStringValue();

        // Check if there is a cached refresh token available.
        IAuthorizationState state = AuthorizationMgr.GetCachedRefreshToken(STORAGE, KEY);
        if (state != null)
        {
            try
            {
                client.RefreshToken(state);
                return state; // Yes - we are done.
            }
            catch (DotNetOpenAuth.Messaging.ProtocolException ex)
            {
                CommandLine.WriteError("Using existing refresh token failed: " + ex.Message);
            }
        }

        // Retrieve the authorization from the user.
        state = AuthorizationMgr.RequestNativeAuthorization(client, scope);
        AuthorizationMgr.SetCachedRefreshToken(STORAGE, KEY, state);
        return state;
    }
private void CreateUserBtn_Click(object sender, EventArgs e)
    {
        // Create Service
        DirectoryService m_serviceUser = new DirectoryService(new BaseClientService.Initializer()
        {
            Authenticator = CreateAuthenticator(),
            ApplicationName = "newuser"
        });           

        // Store data from TextBoxes in form to User-object
        User newuserbody = new User();
        newuserbody.Name = new UserName();
        newuserbody.PrimaryEmail = UserNameTextBox.Text + "@" + DomainTextBox.Text;
        newuserbody.Name.GivenName = GivenNameTextBox.Text;
        newuserbody.Name.FamilyName = FamilyNameTextBox.Text;           
        newuserbody.Password = PasswordTextBox.Text;

        // Create user and store the newly created user in ccreateduser
        User createduser = m_serviceUser.Users.Insert(newuserbody).Execute();

        // display Userdata
        CreatedUserLbl.Text = "User : " + createduser.PrimaryEmail + " has been created!";   

        // Clear inputfields (except for domain)
        UserNameTextBox.Text = "";
        GivenNameTextBox.Text = "";
        FamilyNameTextBox.Text = "";
        PasswordTextBox.Text = "";
    }
