HttpHelper 介紹
HttpHelper 基于 netstandard 2.0 開發，支持.net 4.6.1和.net core專案，能夠方便開發者發送 get 、post 請求，支持設定 cookie、header、代理等，內置將回傳的json字串轉換成物件，
Demo
新建了一個 .net 4.6.1 的專案，低于該框架的將不支持，
nuget命令如下：
Install-Package Sw.Core.HttpHelper
demo功能：get請求獲取原始碼、測驗post提交、獲取圖片、設定代理ip等，
設定 ip 代理訪問，如下圖：
代碼如下：
using Sw.Core.HttpHelper;
using System;
using System.Threading;
using System.Windows.Forms;
namespace HttpHelper_Demo
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();

};
System.Diagnostics.Stopwatch watch = new System.Diagnostics.Stopwatch();
watch.Start();
var result = http.GetHtml(item);
watch.Stop();
if (result.StatusCode== System.Net.HttpStatusCode.OK)
{
base.Invoke(new Action(() =>
{
textBox1.Text = result.Html;
}));
RequestTime(watch.ElapsedMilliseconds);
}
}
catch { }

private void RequestTime(long s)
