Nginx实现部分页面https

由于业务需要，在checkout页面需要实现https加密访问，之前只做过nginx的全站https，对于部分页面https搜索方法有说在代码里直接写成https，有说服务器上直接配置的，做了对比觉得还是nginx上直接配置靠谱。

需求: 全站除了checkout页面https，其他都采取http访问, 如果不符合这个规则的，按照规则强制跳转。

思路: http访问时，在nginx里判断路径包含/checkout，就强制将http转到https；https访问时，判断非checkout，就强制调到http。思路是没有问题，问题是我想用nginx的location实现，研究了半天没找到很好的方案实现[非checkout]. 不过最后还是实现了_,用到了nginx的proxy_pass，下面讲具体实现，最后会放出完整的配置,也许还有问题，欢迎提出。

直接把nginx配置放上来, server_name自行做修改，用了反向代理proxy_pass到负载均衡服务器。
