使用Codable序列化为JSON时，Swift String转义

问题描述

我正在尝试序列化我的对象，如下所示:

I'm trying to serialize my object as following:

import Foundation

struct User: Codable {
    let username: String
    let profileURL: String
}

let user = User(username: "John", profileURL: "http://google.com")

let json = try? JSONEncoder().encode(user)

if let data = json, let str = String(data: data, encoding: .utf8) {
    print(str)
}

但是在macOS上，我得到以下信息:

However on macOS I'm getting the following:

{"profileURL":"http:\/\/google.com","username":"John"}

(请注意转义的'/'字符).

(note escaped '/' character).

在Linux机器上，我得到了:

While on Linux machines I'm getting:

{"username":"John","profileURL":"http://google.com"}

如何使JSONEncoder返回未转义的内容?

How can I make JSONEncoder return the unescaped?

我需要对JSON中的字符串进行严格的转义.

I need the string in JSON to be strictly unescaped.

推荐答案

我最终使用了replacingOccurrences(of:with:)，这可能不是最好的解决方案，但它解决了这个问题:

I ended up using replacingOccurrences(of:with:), which may not be the best solution, but it resolves the issue:

import Foundation

struct User: Codable {
    let username: String
    let profileURL: String
}

let user = User(username: "John", profileURL: "http://google.com")

let json = try? JSONEncoder().encode(user)

if let data = json, let str = String(data: data, encoding: .utf8)?.replacingOccurrences(of: "\\/", with: "/") {
    print(str)
    dump(str)
}
