Am I not supposed to use json api in net.core?

Question

Hi,

I’ve looked into using a Asp.net core API project with my existing MVC.

However there doesn’t seem to be some type of standard way of consuming JSON in MVC or am I missing something?

According to this article I only read it as creating the web api and that it should only be called by JavaScript client side and not from the mvc app?

Hi @Daniel

Webapi can respond to any client that can send Http requests. So webapi is not limited to javascript client access.

You can use HttpClient in asp.net core mvc app, like below:

First, you need add services.AddHttpClient(); in Startup.cs .

public void ConfigureServices(IServiceCollection services)  
{  
    services.AddControllersWithViews();  
    services.AddHttpClient();  
}  

Secod, you can invoke http request in your controller.

public class HomeController: Controller  
{  
        private readonly ILogger<HomeController> _logger;  
        private readonly IHttpClientFactory _clientFactory;  
  
        public HomeController(ILogger<HomeController> logger, IHttpClientFactory clientFactory)  
        {  
            _logger = logger;  
            _clientFactory = clientFactory;  
        }  
       public async Task<String> Test()  
        {  
            var request = new HttpRequestMessage(HttpMethod.Get,  
            "https://learn.microsoft.com/en-us/");  
  
            var client = _clientFactory.CreateClient();  
  
            var response = await client.SendAsync(request);  
  
            if (response.IsSuccessStatusCode)  
            {  
                return await response.Content.ReadAsStringAsync();  
            }  
            else  
            {  
                return "Request Failed ";  
            }  
        }  
}
