今天需要用curl模擬post提交參數,請求同事提供的一個接口;但是傳遞的參數中,有一個參數的值為數組,用普通的curl post代碼提交,會報錯誤
PHP Notice: Array to string conversion in /test/functions.php on line 30
Notice: Array to string conversion in /test/functions.php on line 30
代碼如下:
<?php $param = array( 'uid' => 123, 'uids' => array(12,455), 'msgType' => 'WITH', 'nick' => 'aaa', ); $url = "http://cx.com/t.php"; //通過curl的post方式發送接口請求 SendDataByCurl($url,$param); //通過curl模擬post的請求; function SendDataByCurl($url,$data=array()){ //對空格進行轉義 $url = str_replace(' ','+',$url); $ch = curl_init(); //設置選項,包括URL curl_setopt($ch, CURLOPT_URL, "$url"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch,CURLOPT_TIMEOUT,3); //定義超時3秒鍾 // POST數據 curl_setopt($ch, CURLOPT_POST, 1); // 把post的變量加上 curl_setopt($ch, CURLOPT_POSTFIELDS, $data); //執行並獲取url地址的內容 $output = curl_exec($ch); //釋放curl句柄 curl_close($ch); return $output; }
經過修改上面代碼,可以完成提交數組的功能,而不會報php notice,代碼如下:
//通過curl模擬post的請求; function SendDataByCurl($url,$data=array()){ //對空格進行轉義 $url = str_replace(' ','+',$url); $ch = curl_init(); //設置選項,包括URL curl_setopt($ch, CURLOPT_URL, "$url"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch,CURLOPT_TIMEOUT,3); //定義超時3秒鍾 // POST數據 curl_setopt($ch, CURLOPT_POST, 1); // 把post的變量加上 curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data)); //所需傳的數組用http_bulid_query()函數處理一下,就ok了 //執行並獲取url地址的內容 $output = curl_exec($ch); $errorCode = curl_errno($ch); //釋放curl句柄 curl_close($ch); if(0 !== $errorCode) { return false; } return $output; }
