使用c＃将json字符串数据传递给Rest服务（POST方法） [英] Pass json string data to Rest service (POST Method) using c#

问题描述

在我的项目中，我必须将动态Json字符串传递给WCF Rest服务。这里的输入/输出都应该是Json格式。我正在使用服务器端代码传递我的数据。这是我的代码



在testpage.aspx.cs页面

< pre lang =c＃> string json = { \sjSonData \：[{
+ \log_Id \\ \\：0，
+ \user_Id \：1249，
+ \session_key \：\dvnoewcdw \ ，
+ \app_id\：1，
+ \app_version \：\1.2.7 \，
+ \app_isOnline \：true，
+ \app_dateTimeZone \：\1997-07-16T19：20：30 + 01：00\\，
+ \log_typeId \：1，
+ \log_description\：\valid \
+ }，
+ {
+ \\ \\log_Id \：1，
+ \ user_Id \：1249，
+ \session_key \： \dvnoewcdw \，
+ \app_id\ ：1，
+ \app_version \：\1.2 .7 \，
+ \app_isOnline \：true ，
+ \app_dateTimeZone \：\1997-07 -16T19：20：30 + 01：00 \
+ }] };

const string url = http：//localhost/RestServiceImpl.svc/jsoninputdata;

// 创建对我们需要调用的URL的HTTP请求
HttpWebRequest request =（HttpWebRequest）WebRequest.Create（url）;
request.ContentType = application / json; charset = utf-8; // 将内容类型设置为JSON
request.Method = POST; // 发布HTTP POST

使用（ var streamWriter = new StreamWriter（request.GetRequestStream（）））
{
// 发起请求
JavaScriptSerializer serializer = new JavaScriptSerializer（）;
var resToWrite = serializer.Deserialize< Dictionary< string，object>>（json）;
streamWriter.Write（restoWrite）;
streamWriter.Flush（）;
streamWriter.Close（）;
}

// 获取回复。
WebResponse response = request.GetResponse（）;
var streamReader = new StreamReader（response.GetResponseStream（））;
var result = streamReader.ReadToEnd（）;

我是WCF服务的新手。我不知道如何将此数据传递给Rest服务。在这里，我的输入数据每次通话都有所不同。



休息服务代码

 [ServiceContract] 
  public   interface  IRestServiceImpl 
 {
 [OperationContract] 
 [WebInvoke（Method =   POST，
 ResponseFormat = WebMessageFormat.Json，
 RequestFormat = WebMessageFormat.Json，
 BodyStyle = WebMessageBodyStyle.Bare，
 UriTemplate =   jsoninputdata）] 
  string  jsoninputdata（List<字典< string，object>> rData）; 
} 
 
  public   class  RestServiceImpl：IRestServiceImpl 
 {
  public  jSonResponseData jsoninputdata（List< Dictionary< string，object>> rData）
 {
  string  json = JsonConvert.SerializeObject（rData）; 
  //  在这里做我的东西.....  
  return  ojSonRes;  //  这里我需要返回下面提到的输出 
} 
} 

我需要返回如下数据（输出），



条件1： 如果两者都保存在db中没有任何错误，



{sjSonData：[{成功：true}]}



条件2： 假设任何一个数据都无法保存在数据库中



{sjSonData：[{log_Id：1，success：false}，{log_Id：2，success：true}] }



现在我得到的结果如下，



{sjSonData：{}}



我做错了什么!!!!!还请解释我在web.config文件中要做的所有更改。

In my project i have to pass dynamic Json string to WCF Rest service. Here both Input / Output should be in Json format. I am using server side code to pass my data. Here is my code

In testpage.aspx.cs Page

string json = "{\"sjSonData\":[{"
                             + "\"log_Id\" : 0,"
                             + "\"user_Id\" : 1249,"
                             + "\"session_key\" : \"dvnoewcdw\","
                             + "\"app_id\" : 1,"
                             + "\"app_version\" :\"1.2.7\","
                             + "\"app_isOnline\" : true,"
                             + "\"app_dateTimeZone\" : \"1997-07-16T19:20:30+01:00\","
                             + "\"log_typeId\" : 1,"
                             + "\"log_description\" : \"valid\""
                         + "},"
                         + "{"
                             + "\"log_Id\" : 1,"
                             + "\"user_Id\" : 1249,"
                             + "\"session_key\" : \"dvnoewcdw\","
                             + "\"app_id\" : 1,"
                             + "\"app_version\" : \"1.2.7\","
                             + "\"app_isOnline\" : true,"
                             + "\"app_dateTimeZone\" : \"1997-07-16T19:20:30+01:00\""
                             +"}]}";

const string url = "http://localhost/RestServiceImpl.svc/jsoninputdata";

       //create an HTTP request to the URL that we need to invoke
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);                
            request.ContentType = "application/json; charset=utf-8"; //set the content type to JSON
            request.Method = "POST"; //make an HTTP POST

            using (var streamWriter = new StreamWriter(request.GetRequestStream()))
            {
                //initiate the request
                JavaScriptSerializer serializer = new JavaScriptSerializer();
                var resToWrite = serializer.Deserialize<Dictionary<string, object>>(json);
                streamWriter.Write(restoWrite);
                streamWriter.Flush();
                streamWriter.Close();
            }

            // Get the response.
            WebResponse response = request.GetResponse();                
            var streamReader = new StreamReader(response.GetResponseStream());                
            var result = streamReader.ReadToEnd();

I am new to WCF service. I don't know how to pass this data to Rest service. Here my input data has been differed every call.

Rest Service code

[ServiceContract]
 public interface IRestServiceImpl
 {
   [OperationContract]
        [WebInvoke(Method = "POST",
            ResponseFormat = WebMessageFormat.Json,
            RequestFormat = WebMessageFormat.Json,
            BodyStyle = WebMessageBodyStyle.Bare,
            UriTemplate = "jsoninputdata")]
    string jsoninputdata(List<Dictionary<string, object>> rData);
 }    

 public class RestServiceImpl : IRestServiceImpl
 {    
      public jSonResponseData jsoninputdata(List<Dictionary<string, object>> rData)
      {       
          string json = JsonConvert.SerializeObject(rData);
          //Do my stuff here.....    
          return ojSonRes; // Here i need to return my output mentioned below
      }
  }

And i need to return data (output) like below,

Condition 1: If both saved in db without any error,

{"sjSonData":[{ "success":true }]}

Condition 2: Suppose any one data failed to save in database then

{"sjSonData":[ { "log_Id":1, "success":false }, { "log_Id":2, "success":true } ]}

Now I am getting result like,

{"sjSonData":"{}"}

Am i doing anything wrong!!!!! and also please explain what are all changes i have to do in web.config file.
