json - NSJSONSerialization - 无法在 Swift 上将数据转换为字符串

Question

我有一个带有 Json 的 tableView 并且工作完美，但是今天我们更新了 Json，现在无法工作。我遇到这个问题:

Error with Json: Error Domain=NSCocoaErrorDomain Code=3840 "Unable to convert data to string around character 5060." UserInfo={NSDebugDescription=Unable to convert data to string around character 5060.}

我找到了这篇文章，我认为可行，但是 Obj-c NSJSONSerialization - Unable to convert data to string

let requestURL: NSURL = NSURL(string: rutaJSon)!
    let urlRequest: NSMutableURLRequest = NSMutableURLRequest(URL: requestURL)
    let session = NSURLSession.sharedSession()
    let task = session.dataTaskWithRequest(urlRequest) {
        (data, response, error) -> Void in

        let httpResponse = response as! NSHTTPURLResponse
        let statusCode = httpResponse.statusCode

        if (statusCode == 200) {
            self.arrayNombre.removeAll()
            self.arrayTel.removeAll()
            self.arrayMov.removeAll()


            do{

                let json = try NSJSONSerialization.JSONObjectWithData(data!, options:.AllowFragments)

                //print(json)

有人可以帮助我吗？谢谢

您的服务器似乎没有使用正确的 JSON 编码类型之一。来自文档:

The data must be in one of the 5 supported encodings listed in the JSON specification: UTF-8, UTF-16LE, UTF-16BE, UTF-32LE, UTF-32BE. The data may or may not have a BOM. The most efficient encoding to use for parsing is UTF-8, so if you have a choice in encoding the data passed to this method, use UTF-8.

您的服务器需要对数据进行正确编码。
