正在从web服务的httpresponse中检索json响应

本文关键字：检索 json 响应 httpresponse web 服务 | 更新日期: 2023-09-27 18:29:19

我有一个web服务，它接收json字符串并返回json字符串。但在收到httpwebresponse形式的响应后，我得到{"年龄"："29"，"姓名"："亚历克斯"}。

我怎么能只得到{"age"："29"，"name"："Alex"}，因为上面的响应没有被反序列化。

详细信息类别：

 public class Details
        {
           public String name { get; set; }
           public String age { get; set; }
        }

Web服务代码：

[WebMethod]
            [ScriptMethod(UseHttpGet=true, ResponseFormat = ResponseFormat.Json)]     
            public String getDetails(String details)
            {
                Details d;
                Details retval=(Details)new JavaScriptSerializer().Deserialize(details, typeof(Details));
                retval.age = 29.ToString();
                String result =  new JavaScriptSerializer().Serialize(retval);
                return result;
            }

客户端代码：

class Program
      {
        static void Main(string[] args)
         {
           Details details = new Details();
           details.name = "John";
           details.age = "24";
           String jsonString = new JavaScriptSerializer().Serialize(details);
           var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://localhost/JsonService/service1.asmx/getDetails");
           httpWebRequest.ContentType = "application/x-www-form-urlencoded; charset=utf-8";
           httpWebRequest.Method = "POST";
           using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
                {
                    jsonString="details="+jsonString;
                    streamWriter.Write(jsonString);              
                }
                try
                {
                var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
                using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
                {
                     result = streamReader.ReadToEnd();
                }
        }
        }
The value of **result** comes as <?xml version="1.0" encoding="utf-8"?>
<string xmlns="http://tempuri.org/">{"age":"29","name":"Alex"}</string>
but I need only {"age":"29","name":"Alex"}

正在从web服务的httpresponse中检索json响应

当您发送数据并期望在JSON格式的响应中返回数据时，请尝试将内容标头更改为application/JSON：

httpWebRequest.ContentType = "application/json; charset=utf-8";

您也可以设置接受标头：

httpWebRequest.Accept = "application/json;";
