PHP之curl实现http与https请求的

httpget方式
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 $res;
}
因为这里用了json_decode。所以这里为数组格式，应该用print_r()来输出。
foreach($res as $key=>$value){
echo $key."---".$value
}
这样可以转换为键值对输出

httppost方式
function httpPost($url,$post_data){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    // post数据
    curl_setopt($ch, CURLOPT_POST, 1);
    // post的变量
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
    $output=json_decode(curl_exec($ch),true);
    curl_close($ch);
    return $data;
}

httpsget方式
function httpsGet($url){
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);// https请求不验证证书和hosts
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
    $res=json_decode(curl_exec($curl),true);
    curl_close($curl);
    return $res;
}

httpspost方式
function httpsPost($url,$post_data){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    // post数据
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // https请求 不验证证书和hosts
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    // post的变量
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
    $output=json_decode(curl_exec($ch),true);
    curl_close($ch);
    return $output;
}
