iPhone Development: Use POST to submit a form
- by Mario
I've got the following html form:
<form method="post" action="http://shk.ecomd.de/up.php" enctype="multipart/form-data">
<input type="hidden" name="id" value="12345" />
<input type="file" name="pic" />
<input type="submit" />
</form>
And the following iPhone SDK Submit method:
- (void)sendfile {
UIImage *tempImage = [UIImage imageNamed:@"image.jpg"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setHTTPMethod:@"POST"];
[request setURL:[NSURL URLWithString:@"http://url..../form.php"]];
NSString *boundary = @"------------0xKhTmLbOuNdArY";
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:NSASCIIStringEncoding]];
[body appendData:[@"Content-Disposition: form-data; name=\"id\"\r\n\r\n" dataUsingEncoding:NSASCIIStringEncoding]];
[body appendData:[@"12345" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"\r\n%@\r\n",boundary] dataUsingEncoding:NSASCIIStringEncoding]];
[body appendData:[@"Content-Disposition: form-data; name=\"pic\"; filename=\"photo.png\"\r\n" dataUsingEncoding:NSASCIIStringEncoding]];
[body appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSASCIIStringEncoding]];
[body appendData:[NSData dataWithData:UIImageJPEGRepresentation(tempImage, 90)]];
[body appendData:[[NSString stringWithFormat:@"\r\n%@",boundary] dataUsingEncoding:NSASCIIStringEncoding]];
// setting the body of the post to the reqeust
[request setHTTPBody:body];
NSError *error;
NSURLResponse *response;
NSData* result = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString* aStr = [[[NSString alloc] initWithData:result encoding:NSASCIIStringEncoding] autorelease];
NSLog(@"Result: %@", aStr);
[request release];
}
This does not work, but I have no clue why. Can you please help me?!! What am I doing wrong?
