what is content type and accept headers code example

Example 1: difference between accept and content type header

Content-Type header is used in POST , PUT , PATCH to specify
the type of body you are sending to the serve and it's required. 

`Accept Header` can be used to ask the server to return
different type of response format 

For example :  

`/api/xname` endpoint , support both xml and json 
as response type so we can add accept header
`application/xml` to get xml result and `application/json` result. 

If server does not support such type ,
it will return `406 not acceptable` status code.

Example 2: accept header in api

`Accept Header` can be used to ask the server to return
different type of response format 

For example :  

`/api/xname` endpoint , support both xml and json
as response type so we can add accept header `application/xml` 
to get xml result and `application/json` result. 

If server does not support such type ,
it will return `406`(not acceptable)  status code.
