How get little value from http

[ar-mokhtari]

<< HTTP GET request >>
If we don't want to get [little] value(s) (like id(s)) in "HEADERS",
which is better?

• Params
• Body
  and why?

[OmidHekayati]

If the little value has a simple structure, It is better to carry on URL params in the HTTP protocol to improve performance. If you carry on the body you need to indicate body content-type, ... just for a very simple data

[ar-mokhtari]

Well, is there any downside to using parameters in the URL?
In other words, if we want to carry something like the "ID" of an entity, (or something like that) and not use "HEADERS", and do not use "BODY" (for the reason you mention),
So do we have any choice other than PARAMS in the URL?
