最后是垃圾。UserInfo={NSDebugDescription=Garbage at end ---> 无法读取数据，因为它的格式不正确 iOS Swift

Question

这是我的网络请求。

//标记:-网络请求

let urlString = Constants.kBaseUrl + Constants.kEventsUrl
Alamofire.request(.GET, urlString, parameters: nil, encoding: .JSON, headers: [Constants.kChecksum:Constants.kChecksumValue]) .responseJSON { response in
    guard response.result.isSuccess else {
        let alertController = UIAlertController(title:"Error", message:response.result.error?.localizedDescription, preferredStyle:UIAlertControllerStyle.Alert)
        let okAction = UIAlertAction(title: "Cancel", style: .Cancel, handler: { action in
            self.isFetchingEvents = false;
            self.eventsFetchError = response.result.error
            self.eventsTableView.reloadData()
        })
        let retryAction = UIAlertAction(title: "Retry", style: .Default, handler: { action in
            self.downloadEvents()
        })
        alertController.addAction(okAction)
        alertController.addAction(retryAction)
        self.presentViewController(alertController, animated: true, completion:  nil);
        return
    }
    let tempInfo = response.result.value![Constants.kData] as! [AnyObject]

//MARK:- and my json response from postman

但是，它总是进入else块并抛出错误

Error Domain=NSCocoaErrorDomain Code=3840 "Garbage at end."UserInfo={NSDebugDescription=结束垃圾})

打印错误描述时，返回"数据格式不正确，无法读取。"

这是我的url:

http://clients.view9.com.np/jwaremap/api/v1/content/events

这是必需的标头键:

("校验和":"3389 dae361af79b04c9c8e7057f60cc6")

在jsonlint.com上验证json结构时，它将其验证为有效的json。在使用。responsestring而不是。responsejson，我得到的结果。

我不知道我错过了什么

谁来告诉我我错过了什么

Answer 1

检查你的web服务响应，它不是一个有效的json，这就是为什么你得到这种错误。

尝试在这里查看您的json响应:- http://jsonviewer.stack.hu/

在您的postman json响应的末尾缺少一个"}"。
