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

问题描述

使用 JsonSerializer.Serialize(obj) 会产生一个转义的字符串，但我想要非转义的版本.例如:

使用系统；使用 System.Text.Json;公开课计划{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;放;}}

将产生一个字符串 {Name":u4F60u597D"} 但我想要 {Name":你好"}

我在

如果您需要在控制台中打印结果，您可能需要安装其他语言.请参阅此处.

Using JsonSerializer.Serialize(obj) will produce an 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":"u4F60u597D"} 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.
