带有额外反斜杠的快速错误消息解析时间

Question

我正在开发一个 swiftui 项目，我需要将特定日期格式的字符串调用发布到 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()
}

如果没有日志记录，代码将无法工作，并且应用程序可以正常运行，并显示以下打印语句：

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

控制台日志：

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": "[email protected]", "gender": "Male"]

@Larme 的回答和链接建议帮助我修复了我的代码错误，这一切都归功于他： 不相关，但是：不需要 .fragmentsAllowed。问题是它会在字符串中的斜杠之前添加反斜杠。它是有效的 JSON，但它似乎是您的服务器解析的问题。

print(body)

有误导性，你想看到的是发送的JSON：

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