谷歌上的操作通过 ASP.NET C# 做出响应

Question

也许有人知道怎么做？为了更好地理解，我附上了截图。我正在使用 ASP.NET。

我成功收到了请求，但我不知道如何处理它以及如何做出回复。例如消息“Test123”

命名空间 GoogleAssistantServer.Controllers

{

[Route("api/[控制器]")]

[ApiController]

public class GoogleController : ControllerBase
{

    [HttpGet]
    public IActionResult Get()
    {
        var result = new Result();
        result.Value1 = 123;

        return Ok(result);
    }
    [HttpPost]
    public async Task<IActionResult> PostWebHook()
    {

        string body;
        using (var reader = new StreamReader(Request.Body))
        {
            body = await reader.ReadToEndAsync();

        }
        return Ok("Test123");
            
    }
}

public class Result
{
    public int Value1 { get; set; }
    public int Value2 { get; set; }

}

}

我应该如何在这里处理请求然后返回一些东西？例如消息“Test123”

这是我得到的，但我不知道如何处理它并发送回响应。

{"handler":{"name":"abc"},"intent":{"name":"actions.intent.MAIN","params":{},"query":"Mit Google sprechen"},"scene":{"name":"actions.scene.START_CONVERSATION","slotFillingStatus":"UNSPECIFIED","slots":{},"next":{"name":"Start_Frage"}},"session":{"id":"ABwppHHVumDrliLJaLSikS6KnIlN7yYv6Z4XJCOYzEZt8Fr08RH6r0wtM2-E0v40lS2p1YosTDfpSCd5Lw","params":{},"typeOverrides":[],"languageCode":""},"user":{"locale":"de-DE","params":{},"accountLinkingStatus":"ACCOUNT_LINKING_STATUS_UNSPECIFIED","verificationStatus":"VERIFIED","packageEntitlements":[],"gaiamint":"","permissions":[],"lastSeenTime":"2021-04-01T10:06:59Z"},"home":{"params":{}},"device":{"capabilities":["SPEECH","RICH_RESPONSE","LONG_FORM_AUDIO"]}}

请求以 JSON 格式发送给您。您需要将其解析为一个对象，以便您可以使用它。

您需要做的第一件事是定义即将退役的对象。这在request object format 中有记录。

非常基本的例子。

public class Handler
{
    public string name { get; set; }
}

public class Params
{
    public string UserId { get; set; }
    public int NumVisits { get; set; }
}

public class Intent
{
    public string name { get; set; }
    public Params @params { get; set; }
    public string query { get; set; }
}

public class Slots
{
}

public class Next
{
    public string name { get; set; }
}

public class Scene
{
    public string name { get; set; }
    public string slotFillingStatus { get; set; }
    public Slots slots { get; set; }
    public Next next { get; set; }
}

public class Session
{
    public string id { get; set; }
    public Params @params { get; set; }
    public List<object> typeOverrides { get; set; }
    public string languageCode { get; set; }
}

public class User
{
    public string locale { get; set; }
    public Params @params { get; set; }
    public string accountLinkingStatus { get; set; }
    public string verificationStatus { get; set; }
    public List<object> packageEntitlements { get; set; }
    public string gaiamint { get; set; }
    public List<object> permissions { get; set; }
    public DateTime lastSeenTime { get; set; }
}

public class Home
{
    public Params @params { get; set; }
}

public class Device
{
    public List<string> capabilities { get; set; }
}

public class Response
{
    public Handler handler { get; set; }
    public Intent intent { get; set; }
    public Scene scene { get; set; }
    public Session session { get; set; }
    public User user { get; set; }
    public Home home { get; set; }
    public Device device { get; set; }
}

一旦你定义了你的对象，你就可以反序列化请求。

 var values = JsonSerializer.Deserialize<Response>(body);

由于目前还没有人为动作创建库，因此您需要自己做。

同样，对于响应，您需要发回使用response object format 格式化的 JSON。
