+ sign in url.parse?

Question

JavaScript

for example, there is a line
/?test=1&test1=+
execute in node.js

> url.parse('/?test=1&test1=+', true).query
{ test: '1', test1: ' ' }

the plus sign was replaced by a space, if you specify another sign, for example, minus or equal, then everything is ok. what could be the problem?

Answer 1

We read RFC-1866, namely 8.2.1

Answer 2

So in JS, the plus sign seems to be a sign for gluing strings, so for example, when adding two strings, they have to be cast to the Number type, but for example, when subtracting, everything is fine. Just don't use plus in such queries
