我想將圖像數據發送到服務器,爲此,我已將該數據附加到請求的HTTP正文併發送給它。我正在使用下面的代碼。將圖像數據(NSData)發送到服務器
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:@"http://developers.our-works.com/forms/TestReceiver.aspx"]];
[request setHTTPMethod:@"POST"];
NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"];
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];
// now lets create the body of the post
NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@\"\r\n",tempFileName] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imgdata]];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
//data into the string..... verifying............
NSString *strTest = [[NSString alloc] initWithData:body encoding:NSUTF8StringEncoding];
NSLog(@"%@",strTest);
// setting the body of the post to the request
[request setHTTPBody:body];
// now lets make the connection to the web
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
現在我必須發送兩個不同圖像的NSData。所以,只是想問一下,我可以將這兩個不同的圖像的NSData發送到上面的同一個主體中。 或者,我必須爲其他圖像的數據編碼相同的東西。
請幫我解決這個問題。感謝您。
