Question

我在使用Alamofire在Swift 1中创建的应用程序编译时出现问题。问题出现在以下代码中：

func fetchApiData() {

    print("called")

    // I believe this is the problem code below.


    let _requestURL1 = Alamofire.request(.GET,dataSourceURL!)
    _requestURL1.responseJSON { (_requestUrl, _requestResponse, _objJSON1, error) -> Void in
        if(_objJSON1 != nil)
        {
            let jsonResult1 = _objJSON1 as NSDictionary;
            //let jsonResult2: NSDictionary! = NSJSONSerialization.JSONObjectWithData(data,
            //    options:NSJSONReadingOptions.MutableContainers, error: self.error) as NSDictionary
            self.checkIP(jsonResult1)
            self.checkGeo(jsonResult1)
            //println(jsonResult1);
        }
        else{
            return
        }
}

给出的错误说：

Contextual type for closure argument list expects 1 argument, but 4 were specified

我已尝试过here的解决方案，但我无法正常工作。请帮忙！

Answer 1

代码应如下所示

let _requestURL1 = Alamofire.request(.GET,dataSourceURL!)

_requestURL1.responseJSON { response in
let json = JSON(response.data!)
let token = json["token"].string
response(token: token)
}

正如在另一篇文章中所述，在Swift 2中，.responseJSON从4个参数变为仅1个

升级到swift 2
