这可能是由于重定向造成的吗？如果/ post2重定向到/ post2 /，您的POST请求将转换为GET，丢失所有发布数据。

Could this be due to a redirect? If "/post2" redirects to "/post2/" your POST request would be transformed into a GET, losing all post data.

尝试直接访问/ post2你的浏览器，看看会发生什么。

Try accessing "/post2" directly in your browser and see what happens.
