Swoole cURL Hook creates malformed requests to UNIX Sockets

[PineappleIOnic]

Please answer these questions before submitting your issue. Thanks!

1. What did you do? If possible, provide a simple script for reproducing the error. I was attempting to communicate to a Docker Server through cURL and a UNIX Socket with the swoole hook enabled. Docker does not correctly detect the headers and always returns an error message stating that the host header is not correct. Disabling the Swoole hook for cURL fixes this problem however multiple tasks with cURL will stop working.

2. What did you expect to see? The docker request to successfully pass and work correctly.

3. What did you see instead? Docker returns the following error message: 400 Bad Request: malformed Host header stating that the host header is malformed.

4. What version of Swoole are you using (show your php --ri swoole)? Swoole v4.8.2

5. What is your machine environment used (show your uname -a & php -v & gcc -v) ? Uname: Linux 55028506596f 5.10.47-linuxkit #1 SMP PREEMPT Sat Jul 3 21:50:16 UTC 2021 aarch64 Linux Php:

Thank you for reviewing my bug report, if any more details are required please let me know 👍

1. Please provide the complete log of php --ri swoole output.
2. Are you using curl native hook?
3. Do you have set the http host header?

$host = array("Host: your_host");
curl_setopt($ch,CURLOPT_HTTPHEADER,$host);

Yes, We are using the curl native hook enabled with Swoole\Runtime::enableCoroutine(true, SWOOLE_HOOK_ALL); If you would like to take a look at the code we are using to execute calls it can be found here:

https://github.com/utopia-php/orchestration/blob/94540e5a756604836271a9c8f1e2170415daa7cc/src/Orchestration/Adapter/DockerAPI.php#L52-L92

The $headers is set else where within appwrite which is requiring this library

Hey there, Is there any update on this?

[nggit]

I would suggest stream_socket_client as an alternative. This works well. Fortunately, I never use cUrl to make requests through sockets.

I use HTTP 1.0 and the following headers:

// ...

$headers = [
    'Host: localhost',
    'User-Agent: PHP/' . PHP_VERSION,
    'Accept: */*',
    'Content-Type: application/json',
    'Connection: close'
];

// ...

fwrite($handle, sprintf("GET %s HTTP/1.0\r\n%s\r\n\r\n", '/containers/' . urlencode($name) . '/json', implode("\r\n", $headers)));

Same problem here, if using curl to unix socket (CURLOPT_unix_socket_path) inside coroutine context while enabling hooks Co::set(['hook_flags'=> SWOOLE_HOOK_ALL]); seems to not set request headers AND http method even if set via CURLOPT_CUSTOMREQUEST

php --ri swoole

Also this two options are not supported: CURLOPT_PROXY_SSL_VERIFYHOST (not supported error) CURLOPT_PROXY_SSL_VERIFYPEER (not supported error) CURLOPT_CUSTOMREQUEST (no error but misbehave malforming the request) CURLOPT_UNIX_SOCKET_PATH (workaround by @nggit is acceptable for now) i really need this options to call an external service api with PATCH http method and via a non verified https proxy? will be hard o add support for this? how can i help? can someone put me on the right track? ty in advice

ok solved... "pecl install swoole" with or without "--enable-swoole-curl" on Ubuntu 22.04.3 LTS DOES NOT ENABLE SWOOLE_HOOK_NATIVE_CURL so build swoole manually: "pecl uninstall swoole" wget https://github.com/swoole/swoole-src/archive/refs/tags/v5.1.0.zip unzip v5.1. cd swoole-src-5.1.0 apt install libc-ares-dev AND OTHERS REQUIREMENTS phpize ./configure --enable-openssl --enable-brotli --enable-mysqlnd --enable-swoole-curl --enable-cares --enable-swoole sudo make sudo make install php --ri swoole (MAKE ATTENTION TO THE LINE curl-native => enabled)
