c# - Asp.Net Web API to get getails of a particular item -

hi every 1 new asp.net-web-api , want details of particular item item_code has passed in header of postman or in json format.

i did follows

public list<product> getbycode(string itemcode) {     using (var context = new dbcontext())     {         var getitem = (from s in context.objproduct (s.itemcode == itemcode) select s).tolist();         if (getitem!=null )         {             return getitem;         }         else         {             return null;         }     } } 

if doing through query string

localhost:50787/api/product/getbycode?itemcod=3f-47-ab-84-9f-eb-d6-6b-9c-62-cc-85-98-4d-28-6b

as working fine. want has passed through json or header key , values.

please me.

first need post request end point. need edit action [httppost] attribute.

[httppost] public list<product> getbycode(string itemcode) {...} 

i suggest changing name of action posting getbycode can cause confusion name.

with done, lets focus on how send data endpoint.

sending post action

post localhost:50787/api/product/getbycode?itemcod=3f-47-ab-84-9f-eb-d6-6b-9c-62-cc-85-98-4d-28-6b http/1.1 user-agent: fiddler host: localhost:50787 

will work, state

but want has passed through json or header key , values.

passing through header require lot more work on part.

take request example code sent in custom header.

post localhost:50787/api/product/getbycode http/1.1 user-agent: fiddler host: localhost:50787 itemcode: 3f-47-ab-84-9f-eb-d6-6b-9c-62-cc-85-98-4d-28-6b 

you have customize api specific header key , map intended action parameter. more work need do.

to send json body , have still call action simple type, need update action know how deal request.

[httppost] public list<product> getbycode([frombody]string itemcode) {...} 

take note of [frombody] attribute.

using [frombody]

to force web api read simple type request body, add [frombody] attribute parameter:

in above example, web api use media-type formatter read value of itemcode request body. here example client request.

post localhost:50787/api/product/getbycode http/1.1     user-agent: fiddler host: localhost:50787 content-type: application/json content-length: 49  "3f-47-ab-84-9f-eb-d6-6b-9c-62-cc-85-98-4d-28-6b"
