Answer 1

1. Pay attention to the content-type sent by postman each time. Application/x-www-form-urlencoded or application/json

2. If it is json, the json written using raw must be in a standard format, with double quotes for the key and double quotes for the value string.

Answer 2

Try ctx.request.fields
