Question

所以这是我的网络请求。

// MARK： - 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

错误域= NSCocoaErrorDomain代码= 3840“垃圾结束。” UserInfo = {NSDebugDescription =结尾处的垃圾。}）

在打印错误说明时，它会返回 “无法读取数据，因为格式不正确。”

这是我的网址：

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

这是所需的标题密钥：

[ “校验和”： “3389dae361af79b04c9c8e7057f60cc6”]

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

我不知道我错过了哪里

有人请告诉我我错过了哪里..

Answer 1

检查您的网络服务响应，它不是有效的json，这就是您遇到此类错误的原因。

尝试在此处查看您的json响应： - http://jsonviewer.stack.hu/

有一个缺失的perenthesis＆＃39; }＆＃39;在邮递员json回复的最后。

最后的垃圾。“UserInfo = {NSDebugDescription =结尾的垃圾---＆gt;数据无法读取，因为它的格式不正确iOS Swift
