替代方法 - 只需使用 CURL,它会自动解压缩
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_TIMEOUT, 400);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true); // Follow redirects, need this if the url changes
curl_setopt($curl, CURLOPT_MAXREDIRS, 5); //if http server gives redirection responce
curl_setopt($curl, CURLOPT_ENCODING, "gzip"); // the page encoding
$data = curl_exec($curl); // data already decompressed
curl_close($curl);
