"Content-length:".strlen($data)."\r\n" . "Cookie: foo=bar\r\n" . "\r\n", 'content' => $data, ) ); $cxContext = stream_context_create($opts); $sFile = file_get_contents("http://127.0.0.1/reponse.php", false, $cxContext); echo $sFile;
2 使用curl,get获取数据
$url = 'http://www.example.com'; //初始化一个 cURL 对象 $ch = curl_init(); //设置你需要抓取的URL curl_setopt($ch, CURLOPT_URL, $url); // 设置cURL 参数,要求结果保存到字符串中还是输出到屏幕上。 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //是否获得跳转后的页面 curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); $data = curl_exec($ch); curl_close($ch); echo $data;
2.2 使用curl。post获取数据
function curl_post($url, $arr_data){ $post_data = http_build_query($url_data); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFLELDS, $post_data); $data = curl_exec($ch); curl_close($ch); echo $data; } $arr_post = array( 'name'=>'test_name', 'age' => 1 ); curl_post("http://www.explame.com/", $arr_post);
