Description

CapMonster2 has the ability to recognize ReCaptcha2 via images.

How it works

Recognition of separate ReCaptcha2 images via CapMonster 2 is carried out similarly to recognition of ordinary captchas. Only the additional parameters differ.

The request must include the name of the module:
CapMonsterModule=ZennoLab.ReCaptcha2

  • Task ReCaptcha2 - Task or TaskDef

Task

Verbal description of the ReCaptcha2 task.

Not recommended to use.

Examples:

Task=traffic lights
Task=Select all images with crosswalks
Task=Select all images with bicycles

TaskDef

ReCaptcha2 task code.

You can parse the task code from browser traffic.

You can look at the contents of the file to understand what specific values to search: Directory CapMonster \Progs\Modules\ZennoLab.ReCaptcha2new.cm\synonymscodes.cdb

The synonymscodes.cdb file contains correspondense between the task name and its code.

  • IsNotDynamic

It is necessary to specify True when recognizing ReCaptcha2 size 4x4.
And False in other cases.

  • CropOnePicture

Specify True, if the picture wasn’t cropped.
And False, if the picture was cropped.

Sending one image at a time makes sense after the initial clicks - after that single images begin to load. Then it is not recommended to recognize the whole 3х3 again - it is better to create several requests with CropOnePicture=False (sending only really loaded tiles).
