標籤:param i++ .com hid start article 目的 curl default
php比較坑的地方就是實現相同的目的,能夠使用超級多種手段。比方(file_get_contents和fopen以及如今提到的curl以及fsockopen當然還有socket)這對於一個經驗少的程式猿來說,確實比較難選。、
所以非常多情況下,我們須要比較。
搜尋一下網上不負責任的資源。做一個預測。然後親自比較權衡一下。
以下是摘抄的:
function curlRequest($url, $isPost = false, $param = array(), $cookie = null, $header = null, $referer = "", $timeout = 60) { $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); if (is_array($header) && !empty($header)) { //設定header $set_head = array(); foreach ($header as $k => $v) { $set_head[] = "$k:$v"; } curl_setopt($ch, CURLOPT_HTTPHEADER, $set_head); } else { curl_setopt($ch, CURLOPT_HEADER, 0); } if ($isPost === true) { curl_setopt($ch, CURLOPT_POST, $isPost); curl_setopt($ch, CURLOPT_POSTFIELDS, $param); } if (!empty($cookie)) { if (is_array($cookie)) { $cookies = implode(‘;‘, $cookie); } else { $cookies = $cookie; } curl_setopt($ch, CURLOPT_COOKIE, $cookies); } if (!empty($referer)) { curl_setopt($ch, CURLOPT_REFERER, $referer); } if( $timeout > 0 ) { curl_setopt($ch, CURLOPT_TIMEOUT, $timeout); } curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $ret = curl_exec($ch); if (curl_errno($ch)) { $ret = ‘‘; } curl_close($ch); return $ret; }
以下主要是介紹要求標頭的一些資訊
<?phperror_reporting(E_ALL ^ E_NOTICE); ini_set(‘display_errors‘, true);//解釋怎樣使用HTTPHEADER。傳送json格式資料$id = $_POST[‘id‘];$symbol = $_POST[‘symbol‘];$companyName = $_POST[‘companyName‘];$data = array("id" => "$id", "symbol" => "$symbol", "companyName" => "$companyName");$data_string = json_encode($data);curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);curl_setopt($ch, CURLOPT_HTTPHEADER, array( ‘Content-Type: application/json‘, ‘Content-Length: ‘ . strlen($data_string)));?>
一般的過程。我們不會用到那麼複雜:
<?php $startTime = microtime(true); $url = "http://api.k780.com:88/?app=weather.today&weaid=1&appkey=10003&sign=b59bc3ef6191eb9f747dd4e83c99f2a4&format=xml"; for($i = 0 ; $i < 2; $i++){ $handle = curl_init($url); //$defaultHeader = array(‘Accept-encoding: gzip, default‘); curl_setopt($handle, CURLOPT_RETURNTRANSFER, 1); //curl_setopt($handle, CURLOPT_HTTPHEADER, $defaultHeader); curl_setopt($handle, CURLOPT_CONNECTTIMEOUT, 10); curl_setopt($handle, CURLOPT_TIMEOUT, 10); $xml = curl_exec($handle); if($i % 10 == 0){ echo "."; } curl_close($handle); } $endTime = microtime(true); $total = $endTime - $startTime; echo $total; echo curl_error($handle);?

須要說明的是:curl在控制台是不能執行的,比方php xxx.php params_1,它須要server。
