PHP 使用 CURL 发送HTTP请求

//CURL   GET请求
function https_request($url, $data = array()) {
    $curl = curl_init();
    
    if($data){
        $submit_url = $url;
    }else{

        //这里的$data 如果传递的是数组需要   http_build_query($data)
        $submit_url = $url . '?' . http_build_query($data);
    }
    
    curl_setopt($curl, CURLOPT_URL, $submit_url);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl, CURLOPT_TIMEOUT,60);
    
    $output = curl_exec($curl);
    curl_close($curl);
    return $output;
}

//CURL   POST请求
function https_request($url, $data = null) {
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
    if (!empty($data)) {
        curl_setopt($curl, CURLOPT_POST, 1);
        curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
    }
    /*
    curl_setopt($curl, CURLOPT_HTTPHEADER, array(
        'Content-Type: application/json',
        'Content-Length: ' . strlen($data))
    );
    */
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
     curl_setopt($curl, CURLOPT_TIMEOUT,60);
    $output = curl_exec($curl);
    curl_close($curl);
    return $output;
}
