Identification codes 04
what is code?
It is a distinction between the user's public computer or automatic procedures. Code can be prevented: malicious crack the code, brush tickets, forum irrigation, effectively prevent a hacker to crack a particular way ever registered user login attempt with a specific program of violence, in fact, with a verification code is a lot of sites now prevailing way, we use relatively simple way to achieve this functionality.
Both good and bad code verification and reptiles
Sometimes, we want to climb to take some of the user based on some user information, such as crawling Zhang Weibo posts and the number of friends ...... so these times, we need to use some reptiles simulated landing platform, crawling relevant user information of the user after the successful landing. Simulation landing, often appear to obstruct the verification code, and we can not not deal with the verification code, otherwise it is impossible to simulate landing. So, let's look together, or how to deal with the identification code.
Coding cloud platform
Processing code, the most common way is to use a tripartite platform to help us verify the relevant code recognition and processing. A code which cloud platform is a very generic coding platform.

The platform can help us identify the following types of code:
manual
- Cloud coding platform:
- Register (ordinary users and developers users) at the official website
- Developer User login:
- Download example code (development of the document - "call and the latest example of DLL-" PythonHTTP example download)
- Create a software: my software - "Adding new software
- Example code used in the source file to be modified, the value of the data allowed the identification codes in the picture
