静止投影

Question

We are using projection in Rest Web-service. The Approach we are following is:

?projection= (attr1,attr2)&include=0.

where projection string contain name of all the variable which we want to include or exclude from output object. If the include is 0 it means we want to exclude variable and if include is 1 means we want to include variable which are given in projection string . Is this is correct and RESTful?

Answer 1

There's nothing bad in this approach when it comes to being RESTful or RESTless. On the contrary, field projection is very good practice which is widely utilized.

I don't know your scenario well, however the suggested solution seems to be too complicated. I'd rather remove include field and if projection is empty return the whole resource, otherwise return only the fields listed under projection query param.
