我的网页使用snsapi_base网页授权时遇到一个问题，有时候会提示“redirect_uri域名与后台配置不一致”的错误，有时候却又不会，这是什么原因？下面时正常和提示错误的两个url

1、提示错误的url：

https://open.weixin.qq.com/connect/oauth2/authorize?appid=wx54a70169c6558b8f&redirect_uri=https%3A%2F%2Fwww.readse.com%2Fservice%2Fwechat%2Fauth%2Fcallback.action&response_type=code&scope=snsapi_base&state=eyJjIjoibm5saWIiLCJ0IjowLCJhIjp0cnVlLCJpIjoiMTExLjE4LjEzMC4xNjIiLCJ2IjoxfQ==&connect_redirect=1#wechat_redirect

2、没有错误提示的url

https://open.weixin.qq.com/connect/oauth2/authorize?appid=wx54a70169c6558b8f&redirect_uri=https%3A%2F%2Fwww.readse.com%2Fservice%2Fwechat%2Fauth%2Fcallback.action&response_type=code&scope=snsapi_base&state=eyJjIjoiaG5sIiwidCI6MCwiYSI6dHJ1ZSwiaSI6IjExMS4xOC4xMzAuMTYyIiwidiI6MX0=&connect_redirect=1#wechat_redirect
