“UserInfo={NSDebugDescription=Garbage at end ->数据无法读取，因为它没有以正确的格式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]

但是，它总是进入else块并抛出错误。

Error Domain=NSCocoaErrorDomain Code=3840“垃圾堆在尽头”。UserInfo={NSDebugDescription=Garbage at end.})

在打印错误描述时，它返回“由于数据格式不正确而无法读取”。

这是我的网址：

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

这是所需的头键：

"checksum":"3389dae361af79b04c9c8e7057f60cc6"

在使用jsonlint.com验证json结构时，它将其验证为有效的json。关于使用.responseString而不是.responseJSON，我得到了结果。

我不知道我错过了什么

谁能告诉我我错过了哪里..。

Answer 1

检查您的web服务响应--这不是一个有效的json，这就是为什么您会收到这样的错误。

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

在您的邮递员json回复的末尾，有一处遗漏了“}”。
