ASP.NET Core中的PostAsJsonAsync方法在哪里? [英] Where is the PostAsJsonAsync method in ASP.NET Core?

问题描述

我正在ASP.NET Core中寻找PostAsJsonAsync()扩展方法.

I was looking for the PostAsJsonAsync() extension method in ASP.NET Core. Based on this article, it's available in the Microsoft.AspNet.WebApi.Client assembly.

我以为Microsoft已将所有程序集名称从Microsoft.AspNet更改为Microsoft.AspNetCore，以更特定于.NET Core，但我却找不到Microsoft.AspNetCore.WebApi.Client程序集.

I had thought Microsoft had changed all of the assembly names from Microsoft.AspNet to Microsoft.AspNetCore to be more specific to .NET Core, however, and yet I cannot find an Microsoft.AspNetCore.WebApi.Client assembly.

I dont deserve any credit for this. Have a look @danroth27 answer in the following link.

https://github.com/aspnet/Docs/blob/master/aspnetcore/mvc/controllers/testing/sample/TestingControllersSample/tests/TestingControllersSample.Tests/IntegrationTests/HttpClientExtensions.cs

他使用扩展方法.代码如下. (从上面的github链接复制).我在.Net Core 2.0上使用它.

He uses an extension method. Code as below. (Copied from the above github link). I am using it on .Net Core 2.0.

using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading.Tasks;
using Newtonsoft.Json;

namespace TestingControllersSample.Tests.IntegrationTests
{
    public static class HttpClientExtensions
    {
        public static Task<HttpResponseMessage> PostAsJsonAsync<T>(
            this HttpClient httpClient, string url, T data)
        {
            var dataAsString = JsonConvert.SerializeObject(data);
            var content = new StringContent(dataAsString);
            content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
            return httpClient.PostAsync(url, content);
        }

        public static async Task<T> ReadAsJsonAsync<T>(this HttpContent content)
        {
            var dataAsString = await content.ReadAsStringAsync();
            return JsonConvert.DeserializeObject<T>(dataAsString);
        }
    }
}
