curl和file_get_contents都无法通过hosts文件中设置的域名找到服务器

时间:2014-05-04 21:59:36

标签: php curl alias file-get-contents hosts

/etc/hosts上的PHP服务器和客户端上:

192.168.1.111    my-fake-domain-name.com

PHP服务器那个框(192.168.1.111)。但是,当我使用curlfile_get_contents从别名(my-fake-domain-name.com)获取任何内容时,它始终会返回403错误。如果我使用IP地址,一切正常。如何让这些程序识别别名?

//These do NOT work
file_get_contents( "http://my-fake-domain-name.com" );
curl_setopt($ch, CURLOPT_URL, "http://my-fake-domain-name.com" );

//These DO work
file_get_contents( "http://192.168.1.111" );
curl_setopt($ch, CURLOPT_URL, "http://192.168.1.111" );

编辑:在命令行中使用curl可以使用别名。它只在PHP中才能发挥作用。

4 个答案:

答案 0 :(得分:0)

该域名curl -I的输出是多少?这应该显示标题可能的解释。像这样运行:

curl -I my-fake-domain-name.com

Web服务器中显示的内容(我假设Apache?)在my-fake-domain-name.com的服务器上登录?这些日志应位于:

/var/log/apache2/access.log
/var/log/apache2/error.log

您可以使用tail跟踪他们的输出,如下所示:

sudo tail -f -n 200 /var/log/apache2/access.log
sudo tail -f -n 200 /var/log/apache2/error.log

这些路径基于标准的Ubuntu 12.04安装,但对于CentOS和Linux应该是相同的。如果你在Linux上,那么你正在使用的Linux变种。

假设它是在服务器上运行的Apache,你是否有基于Apache名称的虚拟主机?可能是你在192.168.1.111取得了成功,因为这是Apache默认配置返回数据,但你有my-fake-domain-name.com的基于Apache名称的虚拟主机配置,并且Apache配置被破坏了它可能导致403: Forbidden错误。

编辑:由于评论中的原始海报表明问题可能与PHP代码本身有关,因此PHP代码本身可能存在错误,可能导致403.也许{{ 1}}也相关?

另一个编辑:在您的评论中,您说.htaccess设置如此:

ServerAlias

但您似乎缺少ServerAlias my-fake-domain-name.com

ServerName

这是我如何设置虚拟主机的伪代码示例:

ServerName my-fake-domain-name.com

答案 1 :(得分:0)

我们需要知道您的Apache配置对于该虚拟主机条目的样子。你需要确保你有两个

NameVirtualHost 192.168.1.111:80

并且

<VirtualHost 192.168.1.111:80>

在您的配置中,然后您可以将其设为ServerNameServerAlias,但如果没有看到您的配置,我就无法告诉您它有什么问题。您必须具有ServerName。例如,您将使用ServerName mydomain.com,然后在ServerAlias下使用ServerAlias www.mydomain.com subdomain.mydomain.com ...不确定为什么您正在讨论使用Alias,除非您已经拥有使用该IP的域

答案 2 :(得分:0)

添加以下内容,使curlfile_get_contents能够访问网络服务器:

<Directory "/var/www/public_html">
    Allow from all
</Directory>

这需要添加到:80:443虚拟主机声明中。

注意:我不确定为什么需要这样做,因为我之前有Allow from 192.168.1且此服务器位于

之内

答案 3 :(得分:0)

从您的上一次评论开始,一旦您更改了解决问题的Allow from all的访问权限。

我已经看过几次,但你可以尝试添加一个尾随时期:

Order deny,allow
deny from all
Allow from 192.168.1.

注意IP末尾的.尾随

您也可以尝试使用CIDR表示法:

Order deny,allow
deny from all
Allow from 192.168.1.0/24

或者只使用完整的子网:

Order deny,allow
deny from all
Allow from 192.168.1.0/255.255.255.0
