若依微服务-spring-cloud配置HTTPS访问及SSL证书,保姆级，带详细说明

1.场景：安全需要，将原微服务架构的http转为https，并且对已有用户无感；及客户在访问http://a.aa.com时自动转为：https://a.aa.com

2.实现：由于前后端完全分离，使用Nginx做代理，证书选择nginx的SSL证书；

3.nginx配置如下：Linux生产环境自动更改证书目录位置即可，以下实例为windows测试环境，亲测成功；

    worker_connections  2048;

# 不压缩临界值，大于1K的才压缩，一般不用改

# 压缩缓冲区
gzip_buffers 16 64K;
# 压缩版本（默认1.1，前端如果是squid2.5请使用1.0）
gzip_http_version 1.1;
# 压缩级别，1-10，数字越大压缩的越好，时间也越长
gzip_comp_level 5;
# 进行压缩的文件类型
gzip_types text/plain application/x-javascript text/css application/xml application/javascript;
# 跟Squid等缓存服务有关，on的话会在Header里增加"Vary: Accept-Encoding"
gzip_vary on;
# IE6对Gzip不怎么友好，不给它Gzip了
gzip_disable "MSIE [1-6]\.";
