Question

我在MVC控制器中有以下代码，它将示例guid字符串放入HttpResponseMessage中：

public class CertifyController : Controller
{
    [HttpPost]
    public async Task<HttpResponseMessage> NewCertifyOfferRequestAsync(string requestString)
    {
        string activityId = "30dd879c-ee2f-11db-8314-0800200c9a66";

        HttpResponseMessage httpResponseMessage = new HttpResponseMessage();
        httpResponseMessage.Content = new StringContent(activityId);
        return httpResponseMessage;
    }

}

我使用以下代码通过控制台应用程序调用此Controller：

using (HttpClient client = new HttpClient())
{
    client.BaseAddress = new Uri("http://localhost:84928/");

    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

    string requestString = "df5f5587-f1ef-449a-9d20-7f386ea638a8";

    HttpResponseMessage response = await client.PostAsJsonAsync("Certify/NewCertifyOfferRequestAsync", requestString);
    if (response.IsSuccessStatusCode)
    {
        string activityId = await response.Content.ReadAsStringAsync();
        Console.WriteLine("Received activity id: " + activityId);
    }
}

我希望在回复中收到activityId“30dd879c-ee2f-11db-8314-0800200c9a66”。但相反，activityId获得“StatusCode：200，ReasonPhrase：'OK'，版本：1.1，内容：System.Net.Http.StringContent，标题：\ r \ n {\ r \ n内容类型：text / plain; charset来自ReadAsStringAsync调用的“utf-8 \ r \ n}”。

我应该如何更改activityId的赋值，以便它在Controller中生成activityId？

如果是webapi，您应该能够更改方法签名以返回＆＃34;字符串＆＃34;而不是HttpResponseMessage。

e.g

public string Get(int id)
{
    return "value";
}

对于详细示例，您可以使用visual studio创建WebApi Web应用程序，并查看＆＃34; ValuesController.cs＆＃34;
