JSON API .Net Core Put and Patch Examples - rest

Question

I am testing boilerplate library for dotnet core with json:api specification from github repo {json:api}. The endpoints for GET (with or without query), POST & DELETE are working as expected when I send from postman. But I couldn't find working examples to change the existing resource with PUT or PATCH. When i send patch request with data, it give me back response "200 OK" but it didn't change in database. Below are my request and response.
Request GET : http://localhost:5000/api/people -> 200 OK
Response : [
{
"name": "Samuel",
"articles": null,
"id": 2,
"stringId": "2"
},
{
"name": "John",
"articles": null,
"id": 3,
"stringId": "3"
},
{
"name": "Robbin",
"articles": null,
"id": 4,
"stringId": "4"
} ]
Request GET: http://localhost:5000/api/people/2 -> 200 OK
Response : {
"name": "Samuel",
"articles": null,
"id": 2,
"stringId": "2"
}
Request GET: http://localhost:5000/api/people/2?include=articles -> 200 OK
Response : {
"name": "Samuel",
"articles": [],
"id": 2,
"stringId": "2"
}
Request POST: http://localhost:5000/api/people -> 201 Created
Request Body: {"name":"Samuel"}
Response : {
"name": "Samuel",
"articles": null,
"id": 2,
"stringId": "2"
}
Request DELETE: http://localhost:5000/api/people/2 -> 204 No Content
How can I update data?

Answer 1

I made a final decision after reading specification documents of JSONAPI and OData. I will just stick to my own format for better understanding of my own code and I recommend Swagger for Api Documentation. It doesn't make sense if the spec doesn't meet my requirement even when people are telling it's the standard.

Answer 2

I found in documents that require to includes following two headers for different api calls and body request is also different for PATCH.
"Accept: application/vnd.api+json" <--- This needs to put in header
"Content-Type: application/vnd.api+json" <--- This also needed.
Request PATCH: http://localhost:5000/api/people/3 -> 200 OK
// Request body becomes text, anybody knows how to format to JSON?
Request Body(Text): {
"data": {
"type": "people",
"attributes": {
"name": "John"
}
}
}
Response : {
"data": {
"attributes": {
"name": "John"
},
"relationships": {
"articles": {
"links": {
"self":
"http://localhost:5000/api/people/3/relationships/articles",
"related": "http://localhost:5000/api/people/3/articles"
}
}
},
"type": "people",
"id": "3"
} }
