Question

C＃SDK文档遇到的问题，可以在这里找到： http://googleapis.github.io/google-cloud-dotnet/docs/Google.Cloud.Dialogflow.V2/api/Google.Cloud.Dialogflow.V2.SessionsClient.html#Google_Cloud_Dialogflow_V2_SessionsClient_Create_Google_Api_Gax_Grpc_ServiceEndpoint_Google_Cloud_Dialogflow_V2_SessionsSettings_

没有对方法ToChannelCredentials（）的引用。即使空白项目，我们也无法将SDK连接到dialogflow。此方法仍然存在还是不建议使用？

using Google.Cloud.Dialogflow.V2;
using Google.Apis.Auth.OAuth2;
using Grpc.Auth;
using Grpc.Core;
...
GoogleCredential cred = GoogleCredential.FromFile("/path/to/credentials.json");
Channel channel = new Channel(
    SessionsClient.DefaultEndpoint.Host, SessionsClient.DefaultEndpoint.Port, cred.ToChannelCredentials());
SessionsClient client = SessionsClient.Create(channel);
...
// Shutdown the channel when it is no longer required.
channel.ShutdownAsync().Wait();

您是否尝试过使用服务帐户私钥进行连接？（ Json文件）

遵循这些步骤（C＃中的工作示例）

创建Dialogflow代理后，转到代理的设置->常规->单击服务帐户链接
您将被发送到Google Cloud Platform，您可以在其中创建服务帐户
创建服务帐户后，将提供一个选项，用于创建密钥，创建并下载其（JSON）格式
此键将用于从C＃项目连接到Dialogflow代理
在项目中安装 Google.Cloud.Dialogflow.V2 程序包

创建例如Dialogflow管理器类（请在下面查看示例）

    public class DialogflowManager {
    private string _userID;
    private string _webRootPath;
    private string _contentRootPath;
    private string _projectId;
    private SessionsClient _sessionsClient;
    private SessionName _sessionName;

    public DialogflowManager(string userID, string webRootPath, string contentRootPath, string projectId) {

        _userID = userID;
        _webRootPath = webRootPath;
        _contentRootPath = contentRootPath;
        _projectId = projectId;
        SetEnvironmentVariable();

    }

    private void SetEnvironmentVariable() {
        try {
            Environment.SetEnvironmentVariable("GOOGLE_APPLICATION_CREDENTIALS", _contentRootPath + "\\Keys\\{THE_DOWNLOADED_JSON_FILE_HERE}.json");
        } catch (ArgumentNullException) {
            throw;
        } catch (ArgumentException) {
            throw;
        } catch (SecurityException) {
            throw;
        }
    }

    private async Task CreateSession() {
        // Create client
        _sessionsClient = await SessionsClient.CreateAsync();
        // Initialize request argument(s)
        _sessionName = new SessionName(_projectId, _userID);

    }

    public async Task < QueryResult > CheckIntent(string userInput, string LanguageCode = "en") {
        await CreateSession();
        QueryInput queryInput = new QueryInput();
        var queryText = new TextInput();
        queryText.Text = userInput;
        queryText.LanguageCode = LanguageCode;
        queryInput.Text = queryText;

        // Make the request
        DetectIntentResponse response = await _sessionsClient.DetectIntentAsync(_sessionName, queryInput);
        return response.QueryResult;
    }
}

然后可以像这样调用它，例如获取检测意图

     DialogflowManager dialogflow = new DialogflowManager("{INSERT_USER_ID}",
    _hostingEnvironment.WebRootPath,
    _hostingEnvironment.ContentRootPath,
    "{INSERT_AGENT_ID");

var dialogflowQueryResult = await dialogflow.CheckIntent("{INSERT_USER_INPUT}");
