当我要下载PDF时，提交表格后没有发帖请求

Question

I'm writing a script to download a pdf automatically. Firstly, I open the url manually, it will redirect to a login website. and I type my username and password, and click "submit". Then download will start directly. During this procedure, I check the firebug, I find there is no post while I click "submit".

I'm not familiar with this behavior, that means the pdf(300K) is saved before I submit? If there is no post, then I must use some tool like selenium to simulate this "click"?

Answer 1

Is there no request at all, or a GET request? I suspect there is a GET request. In that case, did you turn Persist on in Firebug's Net tab? Possibly the POST request was hidden after redirects.
