Apache无法使用curl发出传出的HTTP请求 [英] Apache cannot make outgoing HTTP Requests using curl
问题描述
请考虑以下系统配置:
- Fedora 27
- 已启用SELinux
- Apache/2.4.33
- PHP 7.1.17
以及下面的代码段，用于向 Sphere-Engine编译器API发出http请求:
And the below code snippet that is used to issue an http request to Sphere-Engine Compilers API:
$ch = curl_init('http://xxxxxxxx.compilers.sphere-engine.com/api/v4/test?access_token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 3.0);
$x = curl_exec($ch);
print_r($x);
当我运行以下CLI时，上面的脚本可以完全正常工作:
The above script works completely fine when I run the following CLI:
php script.php
然后我得到了预期的输出.
And I get the intended output.
但是，当我尝试通过Web浏览器运行它时，会产生:
However, when I try to run it through the web browser it produces:
CURLE_COULDNT_CONNECT(7)无法将connect()连接到主机或代理.
CURLE_COULDNT_CONNECT (7) Failed to connect() to host or proxy.
我发现了很多建议，例如添加
I have found many suggestions such as adding
curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4);
这不是我真正的解决方案.关闭SELinux，我将不这样做.
Which wasn't really a solution for me. Turning off SELinux which I will not do.
注意:当我发布该URL并提供预期的输出时，URL本身也可以正常工作.
Note: The URL itself is working fine when I issue it and gives me the intended output too.
有什么建议吗?预先感谢.
Any suggestions? Thanks in advance.
推荐答案
尝试执行以下操作以查看SELinux是否将使Web服务器连接到网络:
Try this to see if SELinux will let the web server connect to the network:
getsebool httpd_can_network_connect
getsebool httpd_can_network_connect
如果没有，请允许
setsebool -P httpd_can_network_connect上
setsebool -P httpd_can_network_connect on
