Uploading Image from iPhone to Server
Question
**I went through lots of answers in stackoverflow for uploading image from iPhone to server but still couldn't come up with a solution.
It's a simple image upload with an UserID along with it, here's how my code looks**
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init] ;
request.timeoutInterval = 60;
[request setURL:[NSURL URLWithString:url]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"image/png" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"07ee7054-010b-44da-a14f-02e3e66800b7" forHTTPHeaderField:@"userId"];
[request imageData];
conn = [[NSURLConnection alloc]
initWithRequest:request
delegate:self startImmediately:NO];
[conn scheduleInRunLoop:[NSRunLoop mainRunLoop]
forMode:NSDefaultRunLoopMode];
[conn start];
if (conn)
{
receivedData = nil;
receivedData = [NSMutableData data] ;
[receivedData setLength:0];
}
This is how my server side looks,
@RequestMapping(value = "/uploadphoto", method = RequestMethod.POST, headers="Accept = */*")
public Map<String,Object> uploadPhoto(InputStream in,@RequestBody String JSONContentofPOST)
{
return UploadPhoto(in,JSONContentofPOST);
}
The response I'm getting is

Can someone please get me through this? Thanks in advance.

You can't send Content-Type: image/png AND string data at the same time. You need to send a multipart/form-data request instead. You'll need to set up your server to handle that.
