PHP cURL 看不到 /etc/hosts 文件

Question

我在让 PHP cURL 库识别我在 /etc/hosts 文件中创建的别名时遇到了麻烦。

这就是我现在的 /etc/hosts 文件中的内容：

192.168.0.20 www.example.dev

在另一端 (192.168.0.20) Apache 配置为在 example.dev 域。 如果我在浏览器上测试别名，它就可以工作，但使用 PHP cURL 就不起作用。

hosts 文件位于两台计算机上（192.168.0.10 <= PHP cli、192.168.0.20 <= Apache）。

为了完整起见，这是我正在使用的 PHP 代码。

        $this->url = 'http://www.example.dev/';
        $this->ch = curl_init();
        $header = array
        (
            "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
            "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3",
            "Accept-Encoding: gzip,deflate,sdch",
            "Accept-Language: it-IT,it;q=0.8,en-US;q=0.6,en;q=0.4",
            "Cache-Control: max-age=0",
            "Connection: keep-alive",
        );

        $sUserAgent = $this->tor ? UserAgents::getRandom() : UserAgents::CHROME16_LINUX;

        curl_setopt($this->ch, CURLOPT_HTTPHEADER, $header);
        curl_setopt($this->ch, CURLOPT_USERAGENT, $sUserAgent);
        curl_setopt($this->ch, CURLOPT_URL, $this->url);
        curl_setopt($this->ch, CURLOPT_HEADER, false);
        curl_setopt($this->ch, CURLINFO_HEADER_OUT, true);
        curl_setopt($this->ch, CURLOPT_FOLLOWLOCATION, true);
        curl_setopt($this->ch, CURLOPT_RETURNTRANSFER, (bool) $waitResponse);
        curl_setopt($this->ch, CURLOPT_VERBOSE, (bool) $this->verbose);
        curl_setopt($this->ch, CURLOPT_PORT, $this->port);
        curl_setopt($this->ch, CURLOPT_AUTOREFERER, true);
        curl_setopt($this->ch, CURLOPT_MAXREDIRS, 10);
        curl_setopt($this->ch, CURLOPT_ENCODING, '');
        curl_setopt($this->ch, CURLOPT_CONNECTTIMEOUT, 30);
        curl_setopt($this->ch, CURLOPT_TIMEOUT, 60);
        curl_setopt($this->ch, CURLOPT_DNS_CACHE_TIMEOUT, 120);
        curl_setopt($this->ch, CURLOPT_COOKIESESSION, true);
        curl_setopt($this->ch, CURLOPT_COOKIEFILE, 'cookie');

        foreach ($this->files as $k => $file) {
            $this->data['_file_' . $k] = '@' . $file;
        }

        curl_setopt($this->ch, CURLOPT_POST, true);
        curl_setopt($this->ch, CURLOPT_POSTFIELDS, $this->data);

        $this->result = curl_exec($this->ch);

注意：这个问题看起来像这个 但 PHP 相关。

Answer 1

使用此网址“http://192.168.0.20/”而不是“http://www.example.dev”解决了

此外还需要“Host”标头...

$header = array
(
    "Host: www.example.dev", // IMPORTANT
    "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
    "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3",
    "Accept-Encoding: gzip,deflate,sdch",
    "Accept-Language: it-IT,it;q=0.8,en-US;q=0.6,en;q=0.4",
    "Cache-Control: max-age=0",
    "Connection: keep-alive",
);

curl_setopt($this->ch, CURLOPT_URL, 'http://192.168.0.20/');
curl_setopt($this->ch, CURLOPT_HTTPHEADER, $header);

您可能在该 apache 服务器上运行 PHP，但那里没有主机文件条目。
