推荐答案
您可能需要将数据存储在会话或cookie中。重定向只是在响应中添加了额外的标头，告诉浏览器请求重定向到的页面。由于这是触发pageb的请求，因此您从pagea发送的所有标头都将丢失。
You'll probably need to store your data in the Session or a cookie instead. A redirect simply adds additional headers to your response that tells the browser to request the page being redirected to. As this is the request that triggers pageb, all of the headers you sent from pagea are lost.
