Angular HttpClient Get method with body

Question

I\'m improving an existing API, and the requirement is to provide a single get method which can accept multiple search criteria and based on those criteria perform the query

Answer 1

As far as I can tell you cannot use HttpClient get to send a body. You could use the query at least for it to be idiomatic. (Or you can try to force the issue somehow).

Lets say you have an array with your criteria:

const criteria = [ {a: 25}, {b: 23} ];
http.get(url + '/?criteria='+ encodeURIComponent( JSON.stringify(criteria)));

Sending a body in a GET request is a violation of some RFC standard, and even though it might work you're bound to summon some arcane demons.
