I have a problem when i try download file with curl php.
Headers response
PHP Code
$filePath = $this->exchangePath . $this->exchangeFile;
$url = $this->exchangeURL;
$fp = fopen($filePath, 'w');
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_FILE, $fp);
$data = curl_exec($ch);
curl_close($ch);
fclose($fp);
Preview file data after downloading (106Kb)
Preview file data on server (1.9 Mb – The file will be bigger in the future. Maybe 300Mb or large.)
Help me, please.
>Solution :
the problem is that you’re ignoring that Content-Encoding: gzip header. The server returns the data gzip-encoded, and you’re not un-gzipping it.
Luckily for you, curl has built-in support for gzip decoding (curl has basically supported gzip and deflate decoding forever, but modern versions of curl also support br and zstd)
to enable automatic decoding of supported encodings, simply set
curl_setopt($ch,CURLOPT_ENCODING,'');
- setting CURLOPT_ENCODING to emptystring turns on automatic decoding of all supported encodings.
aalso, you should use the fopen binary mode wb so Windows doesn’t fuck with your \n bytes.
