httphelper 介绍

httphelper 基于 netstandard 2.0 开发，支持.net 4.6.1和.net core项目，能够方便开发者发送 get 、post 请求，支持设置 cookie、header、代理等。内置将返回的json字符串转换成对象。

demo

新建了一个 .net 4.6.1 的项目，低于该框架的将不支持。

nuget命令如下：

install-package sw.core.httphelper -version 1.0.0

demo功能：get请求获取源码、测试post提交、获取图片、设置代理ip等。

设置 ip 代理访问，如下图：

代码如下：

using sw.core.httphelper;
using system;
using system.threading;
using system.windows.forms;

namespace httphelper_demo
{
    public partial class form1 : form
    {
        public form1()
        {
            initializecomponent();
        }
