Alamofire仅在真实设备上的字符0无效值

Question

Node.js的

router.get('/mp3', function(req, res, next) {

var lists = [

{
    title : "Conversation 01", desc : "xxxx" , url : "xxxx"


},
{
    title : "Conversation 02", desc : "xxxx" , url : "xxxx"

}



];
res.json(lists);
});

Swift 2.1

Alamofire.request(.GET, "https://myserver/mp3", parameters: ["foo": "bar"])
.responseJSON { response in
print(response.request) // original URL request
print(response.response) // URL response
print(response.data) // server data
print(response.result) // result of response serialization

         if let JSON = response.result.value {
             print("JSON: \(JSON)")
         }
     }

  

错误域= NSCocoaErrorDomain代码= 3840“周围的值无效   字符0.“UserInfo = {NSDebugDescription =周围的值无效   字符0。

错误仅在真实设备上返回！ iOS模拟器没问题！

  

通过为参数添加“nil”来解决问题！
