- method - It is just like tools we use as usual and, to a certain extent, will impact the result at last.
- params - It has a great influence on the web page as well as the data we get.
- headers - It is said that when we pay a visit to one page, we need some stuff to identify who we are and they will make a decision about whether to give us access to it.
