Nginx下400 Bad Request The plain HTTP request was sent to HTTPS port的原因

 upstream payment443{

server10.11.157.111:443backup;

server10.11.157.222:443weight=1;

}

Location~/payment/{

ssion;

proxy_passhttp://payment443;

include/opt/apps/nginx/conf/proxy.conf;

因为我配置的跳转是走HTTPS协议的443端口，但nginx下Location确是配置的是HTTP协议，所以应该把HTTP改成HTTPS，例如上面得改为proxy_pass http://payment443就可以了。
