给nginx配置SSL证书之后，https可以正常访问，http访问显示400错误，nginx的配置如下：server { listen 80 default backlog=2048; listen 443; server_name wosign.com; root /var/www/html; ssl on; ssl_certificate /usr/local/Tengine/sslcrt/ wosign.com.crt; ssl_certificate_key /usr/local/Tengine/sslcrt/ wosign.com .key; }http访问的时候，报错如下：400 Bad RequestThe plain HTTP requset was sent to HTTPS port. Sorry for the inconvenience.Please report this message and include the following information to us.Thank you very much! 说是http的请求被发送到https的端口上去了，所以才会出现这样的问题。
server { listen 80 default backlog=2048; listen 443 ssl; server_name wosign.com; root /var/www/html; ssl_certificate /usr/local/Tengine/sslcrt/ wosign.com.crt; ssl_certificate_key /usr/local/Tengine/sslcrt/ wosign.com .Key; }把ssl on；这行去掉，ssl写在443端口后面。这样http和https的链接都可以用，完美解决。
