Swift Alamofire Escape a JSON

Question

我正在使用swift Alamofire，但我遇到了一个问题，我想将数据传递给服务器，但服务器需要转义的JSON字符串，如下所示

{\"status\":1,\"id\":\"1bcc3331b09d32f7439ad9d5f2acfb35\",\"progress\":[{\"airline_code\":\"SRI\",\"ctr\":0,\"rate\":5,\"state\":1,\"data\":null}]}

但我从响应中得到了以下数据：

{"status":1,"id":"1bcc3331b09d32f7439ad9d5f2acfb35","progress":[{"airline_code":"SRI","ctr":0,"rate":5,"state":1,"data":null}]}

如何将JSON转换为转义的JSON，

我试过这个在线转换器Converter Escape JSON

而且它的工作很完美，我怎么能在swift Xcode中像这样转义。

更新完整的json (查看提要内部：)

   "flight_child":"0",
   "child":"[]",

   "depart_adult_surcharge":"0",

即使这应该由服务器来修复。一个令人讨厌的破解方法是首先将应该作为字符串传递的json字符串化，然后将出现的双引号替换为\“。

let dic = ["status":1,
               "id":"1bcc3331b09d32f7439ad9d5f2acfb35",
               "progress":[["airline_code":"SRI","ctr":0,"rate":5,"state":1,"data":nil]
    ]

        ] as [String : Any]

    if let json = try? JSONSerialization.data(withJSONObject: dic, options: JSONSerialization.WritingOptions.init(rawValue: 0)) {
        if let str = String(data: json, encoding: String.Encoding.utf8)?.replacingOccurrences(of: "\"", with: "\\\"") {
            print(str)
        }
    }

结果：

{\"id\":\"1bcc3331b09d32f7439ad9d5f2acfb35\",\"status\":1,\"progress\":[{\"state\":1,\"airline_code\":\"SRI\",\"data\":null,\"ctr\":0,\"rate\":5}]}
