1.GET请求：

NSString *urlStr = [NSStringstringWithFormat:@"http://192.168.3.251/~apple/itcast/login.php?username=%@&password=%@",_userName.text,_password.text];

NSURL *url = [NSURL URLWithString:urlStr];

NSURLRequest *request = [NSURLRequestrequestWithURL:url];

NSURLConnection *connection = [NSURLConnectionconnectionWithRequest:request delegate:self];

[connection start];

2.POST请求

NSString *urlStr = [NSStringstringWithFormat:@"http://192.168.3.251/~apple/itcast/login.php"];

NSURL *url = [NSURL URLWithString:urlStr];

NSMutableURLRequest *request = [NSMutableURLRequestrequestWithURL:url];

request.HTTPMethod = @"POST";

NSString *bodyStr = [NSStringstringWithFormat:@"username=%@&password=%@",_userName.text,_password.text];

request.HTTPBody = [bodyStr dataUsingEncoding:NSUTF8StringEncoding];

NSURLConnection *connection = [NSURLConnectionconnectionWithRequest:request delegate:self];

[connection start];

3.同步请求，和异步请求

//异步请求

[NSURLConnection sendAsynchronousRequest:<#(NSURLRequest *)#> queue:<#(NSOperationQueue *)#> completionHandler:<#^(NSURLResponse *response, NSData *data, NSError *connectionError)handler#>];

//同步请求

[NSURLConnection sendSynchronousRequest:<#(NSURLRequest *)#> returningResponse:<#(NSURLResponse *__autoreleasing *)#> error:<#(NSError *__autoreleasing *)#>];

4.数据安全
