C# 读取 http post 结果

Question

我在将示例 guid 字符串放入 HttpResponseMessage 的 MVC 控制器中有以下代码：

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;
    }

}

我正在使用以下代码通过控制台应用程序调用此控制器：

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);
    }
}

我希望在响应中收到 activityId“30dd879c-ee2f-11db-8314-0800200c9a66”。但是 activityId 从 ReadAsStringAsync 调用中获取 "StatusCode: 200, ReasonPhrase: 'OK', Version: 1.1, Content: System.Net.Http.StringContent, Headers:\r\n{\r\n Content-Type: text/plain; charset=utf-8\r\n}"。

我应该如何更改 activityId 的分配，以便它获得在 Controller 中生成的 activityId？

如果它是 webapi，您应该能够将方法签名更改为 return a "string" 而不是 HttpResponseMessage。

例如

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

有关详细示例，您可以使用 visual studio 创建 WebApi 网络应用程序，并查看 "ValuesController.cs"
