Question

我创建一个Web API。它的主要目的是向另一个服务器发出请求，并从该服务器获得响应。我成功获得了特定服务器的响应。

我在下面得到响应（它的JSON格式）。

{
    "id": "test@gmail.com",
    "active": 1,
    "is_logged": true,
    "token": "hsja3t56yJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VybmFtZSI6InRlc3RAZHZlby5jb20iLCJwYXNzd29yZCI6InRlc3QyMDE4KyIsImV4cGlyZU9uIjoiMjAxOS0wNi0yMVQwNTozNzowOC4xODhaIn0.3wgGeL_HvcoEJJeEF7tj8jeXk2uIKpOoi9ewmK5yhteh",
    "status": "OK",
    "usertype": "TestUser",
    "msg": "Login Successfull."
}

我尝试使用拆分功能进行分离

string[] sep = response.Split(',');

foreach (string any in sep)
    Console.WriteLine(any);

//string[] colon = sep[0].Split(':');
string[][] colon = sep.Select(x => x.Split(':')).ToArray();

//int count = colon.Count();
for (int i = 0; i <= colon.Length; i++)
{
     Console.WriteLine(colon[i][0]);
     Console.WriteLine(colon[i][1]);           
}

还有其他方法来分隔响应吗？我还将所有字段用于其他目的。

根据您的响应属性创建一个类：

    public class UserData
    {
        public string id { get; set; }
        public int active { get; set; }
        public bool is_logged { get; set; }
        public string token { get; set; }
        public string status { get; set; }
        public string usertype { get; set; }
        public string msg { get; set; }
    }

在读取响应数据时，请使用JsonConvert.DeserializeObject

    string response = "{\"id\":\"test @gmail.com\",\"active\":1,\"is_logged\":true,\"token\":\"hsja3t56yJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VybmFtZSI6InRlc3RAZHZlby5jb20iLCJwYXNzd29yZCI6InRlc3QyMDE4KyIsImV4cGlyZU9uIjoiMjAxOS0wNi0yMVQwNTozNzowOC4xODhaIn0.3wgGeL_HvcoEJJeEF7tj8jeXk2uIKpOoi9ewmK5yhteh\",\"status\":\"OK\",\"usertype\":\"TestUser\",\"msg\":\"Login Successfull.\"}";
    var responseData = JsonConvert.DeserializeObject<UserData>(response);

        //here the print in JSON Data

        Console.WriteLine("id : " + responseData.id);
        Console.WriteLine("active : " + responseData.active);
        Console.WriteLine("is_logged : " + responseData.is_logged);
        Console.WriteLine("token : " + responseData.token);
        Console.WriteLine("status : " + responseData.status);
        Console.WriteLine("usertype : " + responseData.usertype);
        Console.WriteLine("msg : " + responseData.msg);

这是我自己的示例，可以从JSON字符串获取属性，您可以使用它。

但是首先，您需要安装此软件包：-> Newtonsoft.Json.Linq以访问JObject

using System;
using Newtonsoft.Json.Linq;

public class Program
{
     public static void Main()
     {      
           string jsonString = "{\"firstname\":\"Alex Wu\",\"lastname\":\"type\"}";
           JObject jObject = JObject.Parse(jsonString); 
           string firstname = (string)jObject.SelectToken("firstname");
           string lastname = (string)
           Console.WriteLine("{0}", firstname);
           Console.ReadLine();
     }
}

通过添加NuGet包来使用Newtonsoft.json.dll，然后将响应转换为json对象

JObject jo = JObject.Parse(searchCondition);

foreach (JToken child in jo.Children()) {
    var prop = child as JProperty;
    if (prop.Value != null && !string.IsNullOrEmpty(prop.Value.ToString())) {
        string name=prop.Name;
        string value = prop.Value;
        //You can now do whatever with the values like put in a list of object
    }
}

如何在ASP.NET控制台应用程序中分离JSON数据？
