HTTP Get
Create requestNSString *str = @"http://my_server/get.php?name=brian&gender=male"; NSString *str_enc = [str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSURL *url = [[NSURL URLWithString:str_enc] retain]; NSURLRequest *req = [NSURLRequest requestWithURL:url]; NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:req delegate:self];
Prepare delegate
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response; - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data; - (void)connectionDidFinishLoading:(NSURLConnection *)connection; - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error;
HTTP Post
NSString *content = @"name=brian&gender=male"; NSData *postData = [content dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]]; NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:@"http://my_server/post.php"]]; [request setHTTPMethod:@"POST"]; /* Header */ [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; /* Content */ [request setHTTPBody:postData]; connect = [[NSURLConnection alloc] initWithRequest:request delegate:self]; // 跟GET一樣設定4組delegate去接response
