Question

这是我的反馈json字符串：

{"name":"abc", "cardNumber":"1234567890", "data": [{A data},{B data}...]}

我使用此函数发送数据，然后获取json并编码：

func uploadData(word:String){
    var request = URLRequest(url: url!, cachePolicy: .reloadIgnoringLocalAndRemoteCacheData, timeoutInterval: 30)
    request.httpMethod = "POST"
    request.httpBody = word.data(using: .utf8)
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")
    let session = URLSession(configuration: URLSessionConfiguration.default)
    session.dataTask(with: request, completionHandler: {(data, response, error) in
        if let data = data{
            do{
            let data = try JSONSerialization.jsonObject(with: data, options: JSONSerialization.ReadingOptions.mutableContainers)
                print(data) //I want to know what is this so I print
            }catch{
                print(error.localizedDescription)
            }
        }
    }).resume()
}

但控制台总是说：The data couldn't be read because it isn't in the correct format

如果我使用JSONObject.getJSONArray("myValue")...

，这个json可以在android中格式化并读取我尝试使用print(data)（没有json编码）来显示反馈中是否有任何数据，我在控制台中得到400byte，所以我确定有数据发回给我。

更新12/28：

{"name":"abc",
 "cardNumber":"1234567890",
 "data": [{day:20171228, time: 09:10:11},
          {day:20171226, time: 20:00:12},
          {day:20171227, time: 15:30:22}
         ]
}

我确定这个json可以在android中读取，我使用的接收器和发送器是vb.net，它使用sendingString = JsonConvert.SerializeObject(JSONClass)成为json字符串，然后转换为byte发送出去。

更新12/28新 尝试了这么多之后，我发现字符串可以获得反馈，但name的值是中文单词，其他值是英文和数字，只有name是不可读的，现在我检查哪个String.Encoding将起作用，如果我对其成功编码，我将尝试格式化为json数组。

你能尝试一下这个吗？

func uploadData(word:String){
var request = URLRequest(url: url!, cachePolicy: .reloadIgnoringLocalAndRemoteCacheData, timeoutInterval: 30)
request.httpMethod = "POST"
request.httpBody = word.data(using: .utf8)
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
let session = URLSession(configuration: URLSessionConfiguration.default)
session.dataTask(with: request, completionHandler: {(data, response, error) in
    if let data = data{
          if let returnData = String(data: data!, encoding: .utf8) {
          print(returnData)
          } else {
          print("Invalid Data Coming")
         }

        do{
        let data = try JSONSerialization.jsonObject(with: data, options: []) as?  [String: AnyObject]
            print(data) //I want to know what is this so I print
        }catch{
            print(error.localizedDescription)
        }
    }
}).resume()

}
