Selenium Webdriver intercept site verification code

When doing the crawler project, sometimes encounter the problem of verification code, because some site verification code is dynamically generated, even if the same link, at different times access may produce different verification code,

At the beginning of the idea is to open the link to the verification code, and then through the Java code GET request to save the verification code picture to local, and then use the Code tool to parse the verification code, the verification code automatically entered the verification box

Can be the verification code problem solved, but the problem, each request the same address, the resulting code image is not the same, so this method does not work. So you can only use the picture first selenium Webdriver

Intercept to local, and then use the Code tool to parse OK, automatically fill in the verification, very good to solve the problem of the verification code.

The above code, the key code in the Stack overflow get, have to say that Google is still very powerful

Driver.get ("http://www.google.com"); Webelement Ele= Driver.findelement (By.id ("Hplogo"));//Get entire page screenshotFile screenshot =((takesscreenshot) driver). Getscreenshotas (Outputtype.file); BufferedImage fullimg=Imageio.read (screenshot);//Get The location of an element on the pagePoint point =ele.getlocation ();//Get width and height of the elementintElewidth =ele.getsize (). getwidth ();intEleheight =ele.getsize ().
