CURL的GET请求方式的写法~

$url表示请求的路径~ 传参数可直接拼接在路径之后

function httpGet($url) {
$curl = curl_init();
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_TIMEOUT, 500);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_URL, $url);

$res = curl_exec($curl);
curl_close($curl);

return $res;
