由 泄露秘密 提交于 2019-12-13 06:26:18
问题 is there any way or any tools that I could use to get from a SH script, a webpage title, metadata such as descriptions, maybe a little screenshot of the webpage or anything like that? Thanks in advance! 回答1: you could use curl or wget to get the webpage, and then pipe it to sed to get the contents of various tags. It's kludgy as , but that's kinda what you're going to get if you're doing this stuff with a shell script. eg wget http://example.com -O - | grep \<title\>|sed "s/\<title\>\([^<]*\)

由 為{幸葍}努か 提交于 2019-12-13 04:09:21
问题 I want to pull the entire HTML source code file from a website in Java (or Python or PHP if it is easier in those languages to display). I wish only to view the HTML and scan through it with a few methods- not edit or manipulate it in any way, and I really wish that I do not write it to a new file unless there is no other way. Are there any library classes or methods that do this? If not, is there any way of going about this? 回答1: In Java: URL url = new URL("http://stackoverflow.com");
