Section 6: Adding a POST (Restful API in ASP .Net Core)

Introduction:

In the Section 5, we have seen how we can add a HTTP GET method to get the data from the server/API. In this section, let us see how to add a POST method to create a record.

To add a POST method,

• Create a new method Post().
• Post() method should return a list of Movies (model). Hence, let us return IEnumerable<Movie>.
• Post() method will accept a model as Parameter. In our case, it is Movie model. The parameter should have [FromBody], which says that the request data(param) is available in the body of the HTTP Request.
• Add a Data Attribute, [HttpPost] to this method.

Let us see this in action:

To test this,

• Open Postman.
• Create a request and select POST. 
• Add a JSON in the Body of the request.
• Send the request.
