Question

NSMutableString * url = [[NSMutableString alloc] init]; [url appendString : @ "uploadImage.do"];

NSData *imageData = UIImageJPEGRepresentation(selectedImage,1.0); 


// setting up the request object now 
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; 
[request setURL:[NSURL URLWithString:url]]; 
[request setHTTPMethod:@"POST"]; 

/* 
add some header info now 
we always need a boundary when we post a file 
also we need to set the content type 

You might want to generate a random boundary.. this is just the same 
as my output from wireshark on a valid html 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 stringWithFormat:@"Content-Disposition: form-data; name=\"nickname\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithString:appDelegate.userName] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 

[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"password\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithString:appDelegate.passWord] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 

[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"userImage\"\r\n\r\n" ] dataUsingEncoding:NSUTF8StringEncoding]]; 
[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]]; 

//[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
//[body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"userImage\"; filename=\"Default.png\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
//[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]; 

// now lets make the connection to the web 
NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; 
if (theConnection) { 

    receivedData=[[NSMutableData data] retain]; 

} 
else { 

    NSLog(@"Failed"); 

} 

이 코드를 사용하여 이미지를 서버에 업로드하고 있습니다. 아래 명시된대로하고있다 NSData * imageData = UIImageJPEGRepresentation (selectedImage, 1.0);

nil이 아닌 nsdata 개체가 나타납니다. 하지만 내가 그것을 게시하는 경우 서버 측 params로 null이 보내지고있다.
