回答1:

Try using [FromForm] instead of [FromBody] for the method parameter if you're POSTing form data.

回答2:

In Postman, when creating a POST request, the default is "Text". Change it to JSON.

回答3:

In Postman, after ensuring that you're using raw and its in JSON format. Most especially when making GET request and you're not sending any data in the body of the request ensure that the body of the request is not empty. It must have an empty object: { }
