dotnet核心System.Text.Json Unscape Unicode字符串 [英] dotnet core System.Text.Json unescape unicode string

问题描述

使用 JsonSerializer.Serialize（obj）; 将产生一个转义的字符串，但是我想要未转义的版本。例如：

 使用系统； 
使用System.Text.Json; 
 
公共类程序
 {
 public static void Main（）
 {
 var a = new A {Name =你好}; 
 var s = JsonSerializer.Serialize（a）; 
 Console.WriteLine（s）; 
} 
} 
 
 A类{
公共字符串名称{get; set;} 
} 
  

将产生字符串 { Name ： \u4F60\u597D} 但我要 { Name：你好}

我在

如果需要在控制台中打印结果，则可能需要安装其他语言。请在此处。

Using JsonSerializer.Serialize(obj); will produce a escaped string, but I want the unescaped version. for example:

using System;
using System.Text.Json;

public class Program
{
    public static void Main()
    {
            var a = new A{Name = "你好"};
            var s = JsonSerializer.Serialize(a);
            Console.WriteLine(s);
        }
}

class A {
    public string Name {get; set;}
}

will produce a string {"Name":"\u4F60\u597D"} but I want {"Name":"你好"}

I created a code snippet at https://dotnetfiddle.net/w73vnO please help me.

解决方案

You need to set the JsonSerializer options not to encode those strings.

JsonSerializerOptions jso = new JsonSerializerOptions();
jso.Encoder = System.Text.Encodings.Web.JavaScriptEncoder.UnsafeRelaxedJsonEscaping;

Then you pass this options when you call your Serialize method.

var s = JsonSerializer.Serialize(a, jso);        

Full code:

JsonSerializerOptions jso = new JsonSerializerOptions();
jso.Encoder = System.Text.Encodings.Web.JavaScriptEncoder.UnsafeRelaxedJsonEscaping;

var a = new A { Name = "你好" };
var s = JsonSerializer.Serialize(a, jso);        
Console.WriteLine(s);

Result:

If you need to print the result in the console, you may need to install additional language. Please refer here.
