Question

好吧，我将JSON响应设置为nil，但为什么我得到The data couldn’t be read because it isn’t in the correct format.我已经设置了这样的表格视图：

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    if (section==0){
        return 1
    }else{
        if(self.listHistory == nil){
            return 1
        }else{
            if(self.listHistory.count==0){
                return 1
            }else{
                return self.listHistory.count
            }
        }
    }
}

以下是我提出请求的方式：

let apikey = "56c4382d6873f46e7d00000133c2ca8a8220434a4ed619a435f392a8"
    let request = NSMutableURLRequest(URL: NSURL(string: "https://api.123123.biz/123/NonTransactionManager/TransactionHistory")!)
    request.setValue(apikey, forHTTPHeaderField: "APIKey")
    request.HTTPMethod = "POST"
    ZProgressHUD.show("Please Wait")

    NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue()) { (response, data, error) in

        let postString = ("msisdn=\(self.msisdn!)&currentPage=0&pageSize=5&accountID=6&startDate=2016-01-01&endDate=\(tanggal)")
        request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding)
        let task = NSURLSession.sharedSession().dataTaskWithRequest(request) { data, response, error in
            guard error == nil && data != nil else {
                ZProgressHUD.dismiss()
                print("error=\(error)")
                return
            }
            do {
                let response = try NSJSONSerialization.JSONObjectWithData(data!, options: []) as? NSDictionary
                dispatch_async(dispatch_get_main_queue(), {

                    ZProgressHUD.dismiss()
                    self.listHistory = response?.objectForKey("accountHistoryDetails") as! NSArray
                    self.tableView.reloadData()

                })

            }catch let error as NSError {
                print(error.localizedDescription)
            }
        }

        task.resume()
    }

你能告诉我我该怎么做才能摆脱这个错误吗？

尝试以下解决方案：

您需要传递内容类型：

request.addValue（＆＃34; application / json＆＃34;，forHTTPHeaderField：＆＃34; Content-Type＆＃34;） request.addValue（＆＃34; application / json＆＃34;，forHTTPHeaderField：＆＃34; Accept＆＃34;）
let parseJSON = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.MutableContainers) as? NSDictionary

JSON nil响应无法读取数据，因为它的格式不正确
