I'm trying to POST into an API I have made, and I am testing it using Postman. I am getting back a 400 Bad Request error back as a response with the message Invalid JSON message received.
This is an example of the record being feedback to the user using GET.
{
"id":3,
"title":"Radio Etiquette Book",
"summary":"This book provides advice on how to present a radio programme with flair.",
"timestamp":"2016-12-22T18:18:20+0000",
"author":{"id":1,...***},
"reviews":
}
I presume the problem is with author because author contains sub fields, such as ID, username, password and sub classes called entries (books created by that author), and reviews (reviews written by that author).
How can I POST a new entry to avoid a 400 Bad Request error? I'm not sure which value it is, that I am posting incorrectly, but debating on whether it is actually author, and how it should be entered.
You can use a site like JSONLint to inspect whether or not the JSON you're trying to send is properly formatted. It should be able to show you the line of the error and why it might not match the JSON spec.
