PHP之curl實現http與https請求的(轉)

http get請求：

    function httpGet($url){  
        $curl = curl_init();  
        curl_setopt($curl, CURLOPT_URL, $url);  
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);  
        $res=json_decode(curl_exec($curl),true);  
        curl_close($curl);  
        return $res;  
    }  

http post請求：

    function httpPost($url,$post_data){   
        $ch = curl_init();  
        curl_setopt($ch, CURLOPT_URL, $url);  
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);  
        // post數據  
        curl_setopt($ch, CURLOPT_POST, 1);  
        // post的變量  
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);  
        $output=json_decode(curl_exec($ch),true);  
        curl_close($ch);  
        return $data;  
    }  

https get請求：

 

    function httpsGet($url){  
        $curl = curl_init();  
        curl_setopt($curl, CURLOPT_URL, $url);  
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);  
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);// https請求不驗證證書和hosts  
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);  
        $res=json_decode(curl_exec($curl),true);  
        curl_close($curl);  
        return $res;  
    }

 

http get請求：

    function httpsPost($url,$post_data){  
        $ch = curl_init();  
        curl_setopt($ch, CURLOPT_URL, $url);  
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);  
        // post數據  
        curl_setopt($ch, CURLOPT_POST, 1);  
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // https請求 不驗證證書和hosts  
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);  
        // post的變量  
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);  
        $output=json_decode(curl_exec($ch),true);  
        curl_close($ch);  
        return $output;  
    }
