PHP之curl实现http与https请求的

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;
}

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;
}

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;
}

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);
