我有一个dotnet核心1.0应用程序,并试图发布一个Post调用,但我遇到System.Net.Http的问题。我正在使用VSCode在OSX中开发此应用程序。
当它尝试执行Post调用时,我在控制台中收到以下错误:
fail: Microsoft.AspNetCore.Diagnostics.ExceptionHandlerMiddleware[0]
An unhandled exception has occurred: Could not load file or assembly 'System.Net.Http, Version=4.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
System.IO.FileLoadException: Could not load file or assembly 'System.Net.Http, Version=4.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
我在依赖项末尾的project.json文件中添加了以下行'列表并在之后调用dotnet restore
:
"System.Net.Http": "4.1.0"
这些是我的使用陈述:
using System;
using System.IO;
using System.Diagnostics;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Reflection;
using System.Text;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Identity;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using Newtonsoft.Json.Linq;
这是我的方法,我已经剥离调试:
static async Task<JObject> postContent(string url, string content)
{
var httpClient = new HttpClient();
var requestData = new StringContent(
"hhey",
Encoding.UTF8,
"application/json");
HttpResponseMessage response = httpClient.PostAsync(url, requestData).Result;
using (HttpContent responseContent = response.Content)
{
string data = responseContent.ReadAsStringAsync().Result;
return JObject.Parse(data);
}
}
这是我的整个project.json文件:
