Error code 401(unauthorized), if the error code is 401, the web page requests authentication.
This error occurs only when a login password is required to access the web page, whereas when we access using a proxy IP browser, we are redirected to the login window with a password. The reason for this error is that there is no binding authorization whitelist IPIP before using proxy IP or no fixed IP authorization, so you need to bind authorization whitelist IP again, and then enter.
Error code 403(Forbidden), this error code is the code most encountered by crawler users, it means that the server rejected your request.
The reason is generally too many times of crawler crawling, causing too high speed access to the target server, causing the server to judge that the crawler user's IP cannot be accessed normally, thus prohibiting the crawler user's IP. At this time, the user can only replace the new IP address by changing the IP address, that is, the IP is blocked to replace the new IP, which is also the reason why the crawler user needs a large number of proxy IPs.
