asp.net-core - 我们可以从ASP.NET Core应用程序中使用Microsoft.AspNet.WebApi.Client吗？

Question

我们希望能够使用来自我们的ASP.NET Core MVC Web应用程序的Microsoft.AspNet.WebApi.Client包对外部系统进行HTTP调用。它确实可以工作，但是我无法在.NET Core(github)中找到相应的源代码。从ASP.NET路线图的角度来看可以使用此库吗？将来ASP.NET Core是否会支持它？最重要的是，作为ASP.NET Core/.NET Core的一部分，非Windows平台是否将支持此程序包？

您可以尝试我为REST客户端所做的工作。我发现您在最新版本中提到的程序集在最近发布的ASP.Net Core 1.0中不起作用。代替"Microsoft.AspNet.WebApi.Client"，使用"System.Net.Http"。

然后，您将在其中建立这样的Http POST请求的地方:

using AvailabilityPricingClient.Core;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using AvailabilityPricingClient.Core.Model;
using System.Net.Http;
using System.Net.Http.Headers;

namespace AvailabilityPricingClient.Client
{
    public class ProductAvailabilityPricing : IProductAvailabilityPricing
    {
        private HttpClient _client;
        public ProductAvailabilityPricing(string apiUrl)
        {
            _client = new HttpClient();
            _client.BaseAddress = new Uri(apiUrl);
            _client.DefaultRequestHeaders.Accept.Clear();
            _client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        }

        public void Dispose()
        {
            _client.Dispose();
        }


        public async Task<IEnumerable<Availablity>> GetAvailabilityBySkuList(IEnumerable<string> skuList)
        {
            HttpResponseMessage response = _client.PostAsJsonAsync("/api/availabilityBySkuList", skuList).Result;

            if (response.IsSuccessStatusCode)
            {
                var avail = await response.Content.ReadAsAsync<IEnumerable<Availablity>>();
                return avail;
            }

            return null;
        }
    }
}

您现在将像这样构建:

using AvailabilityPricingClient.Core;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using AvailabilityPricingClient.Core.Model;
using System.Net.Http;
using System.Net.Http.Headers;
using Newtonsoft.Json;

namespace AvailabilityPricingClient.Client
{
    public class ProductAvailabilityPricing : IProductAvailabilityPricing
    {
        private HttpClient _client;
        public ProductAvailabilityPricing(string apiUrl)
        {
            _client = new HttpClient();
            _client.BaseAddress = new Uri(apiUrl);
            _client.DefaultRequestHeaders.Accept.Clear();
            _client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        }

        public void Dispose()
        {
            _client.Dispose();
        }

        public async Task<IEnumerable<Availablity>> GetAvailabilityBySkuList(IEnumerable<string> skuList)
        {
            var output = JsonConvert.SerializeObject(skuList);
            HttpContent contentPost = new StringContent(output, System.Text.Encoding.UTF8, "application/json");
            HttpResponseMessage response = _client.PostAsync("/api/availabilityBySkuList", contentPost).Result;

            if (response.IsSuccessStatusCode)
            {
                var avail = await response.Content.ReadAsStringAsync()
                    .ContinueWith<IEnumerable<Availablity>>(postTask =>
                    {
                        return JsonConvert.DeserializeObject<IEnumerable<Availablity>>(postTask.Result);
                    });
                return avail;
            }

            return null;
        }
    }
}

这样，您的界面不会只更改请求代码的主体。

这对我有用。...祝你好运....
