使用Codable序列化为JSON时，Swift String转义

本文介绍了使用Codable序列化为JSON时，Swift String转义的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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: "google") 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","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":"google"}

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