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

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();
        }
