How to use ASP.NET Core APIs in the class library?

08-Jul-2023To use an ASP.NET Core API in a class library, you can use the
HttpClient
class. TheHttpClient
class provides a way to send HTTP requests to an API.To use the
HttpClient
class, you first need to create an instance of the class. You can do this by calling theCreateHttpClient()
method.Once you have created an instance of the
HttpClient
class, you can use it to send a request to the API. You can do this by calling theGetAsync()
method. TheGetAsync()
method takes the URL of the API as its parameter.The
GetAsync()
method will return aTask
object. TheTask
object will contain the response from the API. You can then get the response from theTask
object by calling theResult()
method.The response from the API will be a
HttpResponseMessage
object. TheHttpResponseMessage
object contains the status code of the response, the headers of the response, and the body of the response.You can then use the status code, headers, and body of the response to do whatever you need to do with the response.
The following is an example of how to use the
HttpClient
class to use an ASP.NET Core API in a class library:C#
In this example, we first create an instance of the
HttpClient
class. We then send a request to the API by calling theGetAsync()
method. TheGetAsync()
method takes the URL of the API as its parameter.The
GetAsync()
method will return aTask
object. TheTask
object will contain the response from the API. We then get the response from theTask
object by calling theResult()
method.The response from the API will be a
HttpResponseMessage
object. We then check the status code of the response, the headers of the response, and the body of the response.Finally, we do something with the response.
