发送json流到服务器

本文关键字:服务器 json 发送 | 更新日期: 2023-09-27 18:13:37

我在发送json字符串到asp.net页面的问题,我想发送长流b刚才我正在尝试短一个。我不知道这条路对不对,但我也不知道另外一条路。它不是json格式的!这在c#客户端代码中:

List<Employee> eList = new List<Employee>();
                                    Employee eo = new Employee();
                                    eo = new Employee();
                                    eo.Name = "Santosh";
                                    eo.Age = 24;
                                    eList.Add(eo);
                                    queryString = JsonConvert.SerializeObject(eList, Newtonsoft.Json.Formatting.Indented);
                                    if (flagFirstTime==0)
                                    {
                                        onlineApp = settings.onlinURL + @"/Admin/HR/Attendance_UpdateData.ashx?" + queryString;//here the json string 
                                        urlAdress = onlineApp;
                                        flagFirstTime = 1;
                                    }

                                    Uri url = new Uri(urlAdress);
                                    HttpWebRequest webReq = (HttpWebRequest)WebRequest.Create(url);
                                    webReq.Method = "Get";

和在asp.net页面中:

public void ProcessRequest(HttpContext context) 
    { 
        Teachers_Att_Data teacherAttDataNew; 
        try 
        { 
            var jsonString = String.Empty; 
            var stream = context.Request.InputStream; 
            byte[] buffer = new byte[stream.Length]; 
            stream.Read(buffer, 0, buffer.Length); 
            string xml = Encoding.UTF8.GetString(buffer); 

            context.Response.ContentType = "text/plain"; 
            context.Response.Write("updated"); 
        }  
        catch (Exception ex) 
        { 
                  context.Response.Write("f"); 
        } 

    }

发送json流到服务器

使用Request.Url.Query来读取您发送的字符串,我看到它的方式。所以你的处理器必须是这样的:

public void ProcessRequest(HttpContext context) 
    { 
        Teachers_Att_Data teacherAttDataNew; 
        try 
        { 
            string xml = context.Request.Url.Query.ToString();
            context.Response.ContentType = "text/plain"; 
            context.Response.Write("updated");     
        }  
        catch (Exception ex) 
        { 
                  context.Response.Write("f"); 
        } 
    }

请注意,我不确定其余部分是否有效,或者您的程序中的逻辑是什么,但这是读取url参数的方式。

在url上放置字符串时也使用Server.URLEncode:

onlineApp = settings.onlinURL 
     + @"/Admin/HR/Attendance_UpdateData.ashx?" + Server.URLEncode(queryString);
