swift 带有额外反斜杠的错误消息解析时间

Question

我正在开发一个 swiftui 项目，我需要 post 将特定日期格式的字符串调用到 api 并从中检索响应。

代码如下：

func createProfile(birthday: String, email: String, fullName: String, gender: String, completion: @escaping (Result<Bool, NetworkError>) -> Void) {
    
    guard let url = URL(string: "*******") else {
        completion(.failure(.invalidURL))
        return
    }
    
    var request = URLRequest(url: url)
    let defaults = UserDefaults.standard
    guard let token = defaults.string(forKey: "jsonwebtoken") else {
        return
    }
    request.httpMethod = "POST"
    request.setValue("Bearer \(token)", forHTTPHeaderField: "Authorization")
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")
    let body: [String: String] = [
        "birthday" : "02/01/2022",
        "email": email,
        "fullName": fullName,
        "gender": gender
    ]
    request.httpBody = try? JSONSerialization.data(withJSONObject: body, options: .fragmentsAllowed)
    print(body)
    
    URLSession.shared.dataTask(with: request) { data, response, error in
        guard let data = data, error == nil else {
            completion(.failure(.noData))
            return
        }
        guard let profile = try? JSONDecoder().decode(ProfileResponse.self, from: data) else {
            completion(.failure(.decodingError))
            return
        }
        print(profile)
        completion(.success(profile.activationStatus))
        
        
        
    }.resume()
}

在没有日志记录的情况下，代码无法正常运行，应用程序正常运行，并显示下一个打印语句：

print(String(data: data, encoding: .utf8))

控制台记录：

Optional("{\"errors\":{\"message\":\"parsing time \\"\\\\"02\\\\/01\\\\/2022\\\\"\\" as \\"\\\\"02/01/2006\\\\"\\": cannot parse \\"\\\\/01\\\\/2022\\\\"\\" as \\"/\\"\"}}\n")

打印请求正文时也符合预期：

["birthday": "02/01/2022", "fullName": "Samy", "email": "hello.world@gmail.com", "gender": "Male"]

@Larme 的回答和link的建议帮助我修复了我的代码错误，感谢他： 无关但是：不需要 .fragmentsAllowed。问题是它会在字符串中的斜杠之前添加一个反斜杠。它是有效的 JSON，但它似乎与您的服务器解析有关。 print(body) 是误导，你想看到的是 JSON sent:

print(String(data: request.httpBody!, encoding: .utf8)!)

见 Codable 的，但似乎仅限于 iOS13+。但是您可能有一个 hint/lead 可以搜索...
