C#编写Web设置请求报文都为application/json类型格式

方法一：

创建Web一般处理程序，支持json字符串格式

请求报文例如：

{
"num":"0440200011510190002",
"cls":"stkin",
"ocrTime":"2020-7-23 12:29:30",
"reason":"下错单了"
}

代码：

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using YiRan.BLL.WebApi;

namespace YiRan.WebApi
{
    /// <summary>
    /// YiRanWebHandles 的摘要说明
    /// </summary>
    public class YiRanWebHandles : IHttpHandler
    {

        public void ProcessRequest(HttpContext context)
        {
            context.Response.ContentType = "application/json";
            string sendInfo = string.Empty;
            using (StreamReader reader = new StreamReader(context.Request.InputStream))
            {
                sendInfo = reader.ReadToEnd().Trim();
            }
            if(string.IsNullOrWhiteSpace(sendInfo))
            {
                context.Response.Write("传入字符串不能为空");
                return;
            }
            ActiveStop m = new ActiveStop();
            string res = m.TaskInfo(sendInfo);
            context.Response.Write(res);
        }

        public bool IsReusable
        {
            get
            {
                return false;
            }
        }
    }
}

 第二种 WebService

请求报文例如：

{

 "sendInfo":"{'num':'0440200011510190002','cls':'stkin','ocrTime':'2020-7-23 12:29:30','reason':'下错单了'}"

}
