只下载到了一个几十k的HTML page。实际上Length里那句[text/html]可能已经是个提示了。

Reason：

”It is an HTML "error message", 44k in size, telling the user that there's no valid login and that you should provide credentials (because there's no session cookie).

@LinuxLearner: the --user and --password options only work with FTP or HTTP Basic Authentication, but not with Form-based (eg: input boxes) / session cookie authentication. For that you'll have to resort to screen-scraping, or create a file with a valid cookie, and supply that via the--load-cookiesparameter.“

而我download到的这个HTML里就是login form。
