「Objective-C」正規表現で画像アップロードをする方法
サンプルコード：
– ( IBAction )uploadButton:( id )sender {
UIImage *image = [ UIImage imageNamed : @"1.jpg" ]; //画像名
NSData *imageData = UIImageJPEGRepresentation (image, 0.5 ); //圧縮比例
NSLog ( @" バイト数:%i" ,[imageData length]);
// post url
NSString *urlString = @"http://192.168.1.109:8090/text/UploadServlet" ;
//Serverアドレス
// setting up the request object now
NSMutableURLRequest *request = [[ NSMutableURLRequest alloc ] init ] ;
[request setURL :[ NSURL URLWithString :urlString]];
[request setHTTPMethod : @"POST" ];
NSString *boundary = [ NSString stringWithString : @"—————————14737809831466499882746641449″ ];
NSString *contentType = [ NSString stringWithFormat : @"multipart/form-data;boundary=%@" ,boundary];
[request addValue :contentType forHTTPHeaderField : @"Content-Type" ];
NSMutableData *body = [ NSMutableData data ];
[body appendData :[[ NSString stringWithFormat : @"\r\n–%@\r\n" ,boundary] dataUsingEncoding : NSUTF8StringEncoding ]];
[body appendData :[[ NSString stringWithString : @"Content-Disposition:form-data; name=\"userfile\"; filename=\"2.png\"\r\n" ] dataUsingEncoding : NSUTF8StringEncoding ]]; //アップロード画像名
[body appendData :[[ NSString stringWithString : @"Content-Type: application/octet-stream\r\n\r\n" ] dataUsingEncoding : NSUTF8StringEncoding ]];
[body appendData :[ NSData dataWithData :imageData]];
[body appendData :[[ NSString stringWithFormat : @"\r\n–%@–\r\n" ,boundary] dataUsingEncoding : NSUTF8StringEncoding ]];
[request setHTTPBody :body];
// NSLog(@"1-body:%@",body);
NSLog ( @"2-request:%@" ,request);
NSData *returnData = [ NSURLConnection sendSynchronousRequest :request returningResponse : nil error : nil ];
NSString *returnString = [[ NSString alloc ] initWithData :returnData encoding : NSUTF8StringEncoding ];
NSLog ( @"3- 結果輸出: %@" ,returnString );
