PHP版本： PHP 5.6.21
cURL版本：卷曲7.29.0
网络服务器： Nginx
Linux： Cent OS

描述

我在PHP中有这个CURL。

$headers = array(
"Content-Type: application/x-www-form-urlencoded",
"Authorization: Basic " . $auth_code
);

$data = 'grant_type=authorization_code&code='.$code;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$AUTH_TOKEN_URL);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_TIMEOUT_MS, 1000);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_VERBOSE, TRUE);
curl_setopt($ch, CURLOPT_ENCODING , "gzip");
curl_setopt($ch, CURLOPT_USERAGENT,'php');
curl_setopt($ch, CURLOPT_HTTPHEADER,$headers);
$info = curl_getinfo($ch);
$result = curl_exec($ch);

我做了一个Wireshark捕获，我不任何GET / POST请求启动。

有什么可能阻止它？

我还应该研究什么？

我已经尝试打印出这两个值

**dd($ch);**

I got  

"ch" => curl resource @10 ▼
    url: "https://www.web.com/oauth"
    content_type: null
    http_code: 0

    local_port: 56907
}


**dd($info);** 

I got 

"info" => array:26 [▼

"redirect_url" => ""

"certinfo" => []

似乎没有什么用在那里。

问题

如何继续进行调试？

我现在对任何建议持开放态度。

任何提示/建议/帮助都将非常感谢！

Answer 1

SELinux阻止httpd进程建立网络连接。

setsebool -P httpd_can_network_connect 1

有关详细信息，请参阅httpd_selinux(8)手册页。

Answer 2

如果您需要进一步调查，可以尝试strace。

如果通过访问页面＆＃39; /mycode.php'来触发此代码：

strace -tt -e trace=sendto,connect,open,write,read php /path/to/your/app/mycode.php

如果您的代码是通过框架执行的，或是通过诸如index.php：

之类的入口点处理的

HTTP_HOST=www.yourdomain.com REQUEST_URI=/mycode.php strace -tt -e trace=sendto,connect,open,write,read php /path/to/your/app/index.php

此输出应该能够指向您的问题来源（例如，某些文件未打开，proccesses not started）
