Hello! Thank you for soon reply ! Is there any better method of using Perl to get this web page or get JSON information ? Must though http://antirobot.tianyancha.com/captcha/verify first ? By the way ,if when access, download the authentication code, and then manually enter position, and then submit the manual input position through similar LWP module, access to web pages or JSON information? Whether this method can be ok ? Kindly give me the suggestion ,thanks a lot ~
