[英]Get server response from NSURLSessionUploadTask using custom delegate
I would like to upload an image to a server by using NSURLSessionUploadTask
, which I have already accomplished by using a custom delegate 我想使用
NSURLSessionUploadTask
将图像上传到服务器,这已经通过使用自定义委托完成
let task = NSURLSession(
configuration: NSURLSessionConfiguration.defaultSessionConfiguration(),
delegate: self,
delegateQueue: NSOperationQueue.mainQueue()
).uploadTaskWithRequest(request, fromData: data)
task!.resume()
But I am unable to get the server's response. 但是我无法获得服务器的响应。 Using
task.response
returns the error code and other header information, but does not return the actual html shown on the page. 使用
task.response
返回错误代码和其他标头信息,但不返回页面上显示的实际html。
I can't create the url task with a completion handler, because I need to get the progress of the upload. 我无法使用完成处理程序创建url任务,因为我需要获取上传进度。
How can I get the NSData from a page response using NSURLSessionUploadTask
? 如何使用
NSURLSessionUploadTask
从页面响应中获取NSData?
You can gather the data via didReceiveData
, and could have a global NSData instance and append the received data. 您可以通过
didReceiveData
收集数据,并且可以具有全局NSData实例并追加接收到的数据。
Then, in didCompleteWithError
, you can convert the received data to a string to get the response HTML. 然后,在
didCompleteWithError
,您可以将接收到的数据转换为字符串以获取响应HTML。
