ASP.NET-GET Web请求API

Question

I'm new to APIs, so I've been trying to use a web request to GET information from Reddit, since the API is unlocked. I've been able to use the right URL to get information using a REST client extension, but I want to implement the body of the data and simply just print it out to a web page.

I know this is easier with python, but they use C#/ASP.NET at my work. I've looked off of tutorials such as:

http://www.asp.net/web-api/overview/web-api-clients/calling-a-web-api-from-a-net-client

I was only able to obtain a header when I used this tutorial and my code is:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading.Tasks;

namespace API_TESTING
{
    class Product
    {
        public string Name { get; set; }
        public double Price { get; set; }
    }
    class Program
    {
    static void Main()
    {
        RunAsync().Wait();
    }

    static async Task RunAsync()
    {
        using(var client = new HttpClient())
        {
            //TODO - send HTTP requests
            client.BaseAddress = new Uri("http://www.reddit.com/");
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

            //-----
            HttpResponseMessage response =  await client.GetAsync("r/todayilearned/new.json");
            if(response.IsSuccessStatusCode)
            {
                Console.Write(response);

            }

        }
    }
}
}

Can someone explain how to use ASP.NET for API calls? or link to other up-to-date tutorials? Thank you.

Answer 1

You're almost there. After you get the response, you need to read its content.

var response = await _client.GetAsync(uri);
if (response.IsSuccessStatusCode) {
    var result = await response.Content.ReadAsStringAsync();
    Console.WriteLine(result);
}

You might want to check out the RedditSharp project to see how others have done this. Btw, the tutorial you linked to does almost exactly what I answered with under the Getting a Resource (HTTP GET) section. Only difference is they used the generic ReadAsAsync while you can use ReadAsStringAsync if you're just writing the body to the console.
