A loadrunner was developed a few days ago to use tesseract-ocr to identify the verification code. Although the recognition accuracy is not too high, some verification code images cannot be recognized, however, the correct verification code can also be obtained through the loop method. This method is not recommended in

Currently, many websites require verification codes when users fill out forms. One purpose of the verification code is to prevent malicious websites from downloading software, these software can download all webpages of the website by traversing links. It also prevents users from using website resources without passing through the pages of the website. Therefore, many websites now use the verification code
