php发送post请求的三种方法
/** * 发送post请求 * @param string $url 请求地址 * @param array $post_data post键值对数据 * @return string */ function send_post( $url , $post_data ) { $postdata = http_build_query( $post_data ); $options = array ( 'http' => array ( 'method' => 'POST' , 'header' => 'Content-type:application/x-www-form-urlencoded' , 'content' => $postdata , 'timeout' => 15 * 60 // 超时时间(单位:s) ) ); $context = stream_context_create( $options ); $result = file_get_contents ( $url , false, $context ); return $result ; } //使用方法 $post_data = array ( 'username' => 'stclair2201' , 'password' => 'handan' ); |
