Yesterday is bad for me. I spent almost one day to solve how to login and scrawl data from Linkedin, but failed finally. I tried to use laravel, use curl to simulate login with cookies, etc. It costs me too much time to solve many trivial problems, and I succeeded to make it run in the end, while I can't fetch the data which I want. Because the linkedin has some mechanism to prenvent this illegal behaviour, and not doubt they beat me, since they are a such huge comapny and one thousands times more powerful than me.
The thing I learn is that I need to use some wheels(more powerful tools) to help me , instead do all the things by myself. Nowadays, people use this principle in their daily life. For example, people are using templates to write CV instead originally write by themselves.
