axios is an independent library, which has nothing to do with any framework / library, so why bind to Vue .
in addition to bind apply,call , which can be this each time a function is called, and some methods, such as Array.prototype.map , can set this
callback through the last parameter.
otherwise this all point to the object calling the function
this points to the object that calls him.
suggest taking a look at the scope
