調用使用 HTTP（而非 HTTPS）協議將數據發送到服務器。
所有數據均通過 HTTP 以明文形式發送，容易受到攻擊。
例子 1：以下示例通過 HTTP 協議（而不是 HTTPS 協議）發送數據。
NSString * const USER_URL = @"http://localhost:8080/igoat/user";
...
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:USER_URL]];
[[NSURLConnection alloc] initWithRequest:request delegate:self];
