解决同源策略问题之Apache实现反向代理


我们在没有服务端或者有服务端的时候需要访问不同源数据的时候会出现同源策略问题
因此通过设置Apache的反向代理即可轻松的解决同源策略问题。
有反向代理自然有正向代理，如下图:

理解了反向代理和正向代理我们接下来就可以配置Apache服务器了.

从Apache官网下载apache服务器，解压后打开conf/httpd.conf文件

# Note that from this point forward you must specifically allow

#
# DocumentRoot: The directory out of which you will serve your
# documents. By default, all requests are taken from this directory, but
# symbolic links and aliases may be used to point to other locations.
#
DocumentRoot "C:\Users\Administrator\Documents\HBuilderProject\WebJSApi"
<Directory "C:\Users\Administrator\Documents\HBuilderProject\WebJSApi">
    #
    # Possible values for the Options directive are "None", "All",
    # or any combination of:
    #   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
    #
    # Note that "MultiViews" must be named *explicitly* --- "Options All"
    # doesn't give it to you.
    #
    # The Options directive is both complicated and important.  Please see
    # http://httpd.apache.org/docs/2.4/mod/core.html#options
    # for more information.
    #
    #Options Indexes FollowSymLinks
    #
    # AllowOverride controls what directives may be placed in .htaccess files.
    # It can be "All", "None", or any combination of the keywords:
    #   Options FileInfo AuthConfig Limit
    #
    AllowOverride None
    #
    # Controls who can get stuff from this server.
    #
    Require all granted
</Directory>
最后一步，在conf\extra\httpd-vhosts.conf文件中配置代理服务器

ProxyRequests Off
#ProxyPass / http://www.baidu.com
#ProxyPassReverse / http://www.baidu.com

任何访问代理服务/的请求都会转发到http://www.baidu.com 下面

下面介绍一下Apache的几个常用命令：

httpd.exe -k install 安装Apache服务
httpd.exe -k uninstall 卸载Apache服务
httpd.exe -k start 启动服务
httpd.exe -k stop 停止服务

注意使用这些命令之前切记以管理员身份运行CMD
