Let's talk about your project - captcha.
- First way, we use selenium directly, when captcha appears, make the program pause. In this way, it's easy!
- Second way, we send http requests through HttpWebRequest object, when captcha appears, open webdriver and input captcha, then save cookies and send with HTTP requsts.
- Third way, use proxy, when captcha appears, we change an IP address in HTTP request; another way to use proxy, every request, we change a different Proxy.
From my side, I prefer third way.
I fill 250 USD, Let's start with a small milestone! I can start immediately and I am looking long term job.
