How can nginx redirect a request based on JSON content?

Question

Nginx

NGINX accepts POST requests containing small JSON. Depending on the values ​​of the two fields, requests must be redirected to one or the other upstream.
For example, POST requests come with a body like or . You need to send those from A to , and those from B - to How can this be done by NGINX, without running third-party php scripts? It seems that you can somehow use Lua scripts, but I have never come across this. {"type":"A","data":{...{"type":"B","data":{...https://hostA.domain.tldhttps://hostB.domain.tld

but more flexible to write in lua

Answer 2

No. Nginx does not parse the request BODY. Pass type as a post parameter from the front.
