我想将图像数据发送到服务器,为此,我已将该数据附加到请求的HTTP正文并发送给它。我正在使用下面的代码。将图像数据(NSData)发送到服务器
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];
现在我必须发送两个不同图像的NSData。所以,只是想问一下,我可以将这两个不同的图像的NSData发送到上面的同一个主体中。 或者,我必须为其他图像的数据编码相同的东西。
请帮我解决这个问题。感谢您。
