php中运用http调用的GET和POST方法示例,getpost
使用到的函数是curl_init, curl_setopt, curl_exec,curl_close。
默认是GET方法,可以选择是否使用Header:
$ch = curl_init(); curl_setopt($ch, CURLOPT_URL, "$url"); curl_setopt($ch, CURLOPT_TIMEOUT, 2); curl_setopt($ch, CURLOPT_HEADER, 1); //如果设为0,则不使用header curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); $result = curl_exec($ch); curl_close($ch);
POST方法:
$ch = curl_init(); curl_setopt($ch,CURLOPT_URL,'$url'); curl_setopt($ch,CURLOPT_POST,1); curl_setopt($ch,CURLOPT_RETURNTRANSFER,TRUE); $vars =sprintf('from=%d&to=%d&subject=%s&body=%s',$from, $to, urlencode($subject), urlencode($body)); curl_setopt($ch,CURLOPT_POSTFIELDS,$vars); $ret = curl_exec($ch); curl_close($ch);
HTTP请求有POST和GET。在写表单form时可以指定action为post或get。数组$_POST中保存POST方法传递的变量, $_GET保存GET方法传递的变量。$_REQUEST中包含二者。
