Я пытаюсь загрузить изображение с помощью своего приложения iOS (Swift 2.0). Сервер получает запрос и отправляет статус 200, но когда дело доходит до загрузки файла, данные изображения не загружаются. print_r($_FILES); команда дает мне ответ:
Array ( ) wrong format for image
Это код:
func send() { let request = NSMutableURLRequest(URL: NSURL(string: "***URL to upload.php***")!) request.HTTPMethod = "POST" let postString = "username=\(globalUsr)&photo-name=\(globalImage.description)&photo-description=\(message.text)" let myData : NSData! = postString.dataUsingEncoding(NSUTF8StringEncoding) let imageData :NSData = UIImageJPEGRepresentation(globalImage, 1.0)!; let boundary = "-----SwiftBoundary-----" let contentType = "multipart/form-data; boundary=\(boundary)" let body = NSMutableData(); let tempData = NSMutableData() let fileName = "\(globalImage.description).jpg" let parameterName = "contest-photo" tempData.appendData(myData) tempData.appendData("--\(boundary)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!) let fileNameContentDisposition = "name=\(parameterName)" let contentDisposition = "Content-Disposition: form-data; name=\"\(fileName)\"; \(fileNameContentDisposition)\r\n" tempData.appendData(contentDisposition.dataUsingEncoding(NSUTF8StringEncoding)!) tempData.appendData("Content-Type: \(contentType)\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!) tempData.appendData(imageData) tempData.appendData("\r\n".dataUsingEncoding(NSUTF8StringEncoding)!) body.appendData(tempData) body.appendData("\r\n--\(boundary)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!) request.setValue("\(body.length)", forHTTPHeaderField: "Content-Length") request.HTTPBody = body let task = NSURLSession.sharedSession().dataTaskWithRequest(request) { data, response, error in if error != nil { print("error=\(error)") return } let responseString = NSString(data: data!, encoding: NSUTF8StringEncoding) print("responseString = \(responseString!)") } task.resume() }
Код PHP:

ОБНОВИТЬ:
Если я попробую:
request.setValue(contentType, forHTTPHeaderField: "Content-Type")
Я получил:
data =<22546865 72652069 73206e6f 20757365 722e22> response = <NSHTTPURLResponse: 0x7fcd7e184980> { URL: http://www.clip2gether.com/mobile/app/v1/iOS/upload/upload.php } { status code: 200, headers { "Cache-Control" = "no-store, no-cache, must-revalidate, post-check=0, pre-check=0"; Connection = close; "Content-Type" = "text/html; charset=UTF-8"; Date = "Sun, 04 Oct 2015 20:39:26 GMT"; Expires = "Thu, 19 Nov 1981 08:52:00 GMT"; Pragma = "no-cache"; Server = "Apache/2.4.10"; "Set-Cookie" = "qtrans_cookie_test=1; path=/; domain=www.clip2gether.com"; "Transfer-Encoding" = Identity; "X-Powered-By" = "PHP/5.6.12"; } }
И если я попробую это с линией:
request.setValue(contentType, forHTTPHeaderField: "Content-Type") data =<41727261 79417272 61790a28 0a290a77 726f6e67 20666f72 6d617420 666f7220 696d6167 65> response = <NSHTTPURLResponse: 0x7fdd22f3e660> { URL: http://www.clip2gether.com/mobile/app/v1/iOS/upload/upload.php } { status code: 200, headers { "Cache-Control" = "no-store, no-cache, must-revalidate, post-check=0, pre-check=0"; Connection = close; "Content-Type" = "text/html; charset=UTF-8"; Date = "Sun, 04 Oct 2015 20:46:19 GMT"; Expires = "Thu, 19 Nov 1981 08:52:00 GMT"; Pragma = "no-cache"; Server = "Apache/2.4.10"; "Set-Cookie" = "qtrans_cookie_test=1; path=/; domain=www.clip2gether.com"; "Transfer-Encoding" = Identity; "X-Powered-By" = "PHP/5.6.12"; } }
Поэтому в основном я получаю тот же ответ с установкой значения contentType, как шестнадцатеричный код:
There is no user
и не устанавливая его
ArrayArray ( ) wrong format for image
