Alamofire 4和JSON中的特殊字符

I've got a problem with special characters with Alamofire 4.
The JSON contains æ, ø and å and the browser shows them fine, also my previous solution using SwiftyJSON did.

Alamofire 4 shows something like this instead:

我对Alamofire 4中的特殊角色有意见。JSON包含æ,ø和浏览器显示他们好,也使用SwiftyJSON做我以前的解决方案。Alamofire 4则显示了如下内容:

U00e6

Using this call:

使用这个调用:

Alamofire.request(specificURL, method: .get, parameters: param, encoding: URLEncoding.default, headers: nil).responseJSON { (response: DataResponse<Any>) in
    print(response)
}

What to do to solve this?

Edit:

编辑:

Alamofire.request(url, method: .get, parameters: param, encoding: JSONEncoding.default)
        .responseJSON { response in

            switch response.result {
            case .success(let value) :

                print(response.request)  // original URL request
                print(response.response) // HTTP URL response
                print(response.data)     // server data
                print(response.result)   // result of response serialization

                if let JSON = response.result.value as! [String:AnyObject]!{
                    print("JSON: ",JSON)
                    self.arrUser = Mapper<Users>().mapArray(JSONArray:JSON["user"] as! [[String : Any]])!
                    self.tableView.reloadData()
                }
            case .failure(let encodingError):
                //Print error
            }
    }

I got the issue that I have added æ in json response and try to print.

我有问题,我添加了æjson响应并试着打印。

Output:

输出:

JSON:  Optional(<__NSArrayI 0x600000050320>(
{
    "email_address" = "testwts06@gmail.com";
     username = "testwts06 \U00e6";
},
{
    "email_address" = "testwts01@gmail.com";
    username = "testwts01 \U00eb";
},
{
    "email_address" = "testwts100@gmail.com";
    username = testwts100;
})

While displaying it display in correct format.

同时以正确的格式显示。

Seems the typical serialization error due to wrong JSON encoding, probably your response status code is 3840.

看起来典型的序列化错误是由于错误的JSON编码，可能您的响应状态代码是3840。

JSON text SHALL be encoded in UTF-8, UTF-16, or UTF-32.

JSON文本应该用UTF-8、UTF-16或UTF-32编码。

You could try to convert the response data to correct UTF8 encoding:

您可以尝试将响应数据转换为正确的UTF8编码:

let datastring = NSString(data: response.data!, encoding: String.Encoding.isoLatin1.rawValue)
let data = datastring!.data(using: String.Encoding.utf8.rawValue)
do {
     let object = try JSONSerialization.jsonObject(with: data!, options: .allowFragments)
     let jsonDic = object as! NSDictionary
     print("  ok, successfully converted..\(jsonDic)")
} catch let aError as Error {
     // print and handle aError 
}

Hope it helps you.

Swift 3 update for Ekta's answer:

Swift 3更新:

let encodedURL = specificURL.addingPercentEncoding(withAllowedCharacters: NSCharacterSet.urlQueryAllowed)

Here is a simple String extension that solves the issue:

这里有一个简单的字符串扩展来解决这个问题:

extension String {
    func fixUnicode() -> String {
        var copy = self as NSString
        let regex = try! NSRegularExpression(pattern: "\\\\U([A-Z0-9]{4})", options: .caseInsensitive)
        let matches = regex.matches(in: self, options: [], range: NSMakeRange(0, characters.count)).reversed()
        matches.forEach {
            let char = copy.substring(with: $0.rangeAt(1))
            copy = copy.replacingCharacters(in: $0.range, with: String(UnicodeScalar(Int(char, radix: 16)!)!)) as NSString
        }
        return copy as String
    }
}
