c# - 使用 JSON 发布请求，但服务器端有 Request.Form.Count == 0

Question

我正在尝试使用 POST 方法将 JSON 从控制台应用程序发送到 WebPage.aspx这将对 JSON 进行重新定位，并对数据进行一些思考。请求状态正常，但在服务器端我得到空的 Request.form(不是 null 只是 count = 0)。但是服务器需要从中读取数据。我写的代码只是与另一个页面集成的原型(prototype)，这就是为什么我需要在 Request.form 中发送数据。

你能帮忙修复我的帖子吗？

    public async static void KeepMeLogged()
    {
         string urlPart = "ReadJson";
         string BaseUrl = "https://baseurl/external-api/"
         HttpClient client = new HttpClient();
         client.BaseAddress = new Uri(BaseUrl);
         client.DefaultRequestHeaders.Accept.Clear();
         client.DefaultRequestHeaders.Accept.Add(
         new MediaTypeWithQualityHeaderValue("application/json"));

    ForRequest json = new ForRequest
    {
        Login = Login
    };

    try
    {
        string stringJson = await Task.Run(() => JsonConvert.SerializeObject(json));
        var httpContent = new StringContent(stringJson, Encoding.UTF8, "application/json");

        using (var httpClient = new HttpClient())
        {
            // Do the actual request and await the response
            var httpResponse = await httpClient.PostAsync(BaseUrl + urlPart, httpContent);

            // If the response contains content we want to read it!
            if (httpResponse.Content != null)
            {
                Console.WriteLine("IsOk");
            }
        }
    }
    catch (Exception e)
    {
        Console.WriteLine(e.Message);
    }
}

public class ForRequest
{
    [JsonProperty("login")]
    public string Login { get; set; }
}

//ServerSide, Request.Form.Count always 0
public partial class ReadJsonPage : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (Request.Form != null)
        {

            foreach (string key in Request.Form)
            {
                   //Request.Form.Count == 0
                   //do something
            }
        }

    }
}

您可以使用此代码获取您的 json 数据:

Request.InputStream.Seek(0, System.IO.SeekOrigin.Begin);
using (var sr = new System.IO.StreamReader(Request.InputStream))
{
    string json = sr.ReadToEnd();
}
