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();
}
private void button1_click(object sender, eventargs e)
{

{
try
{
var http = new httphelper();
var item = new httpitem()
{
url = "https://www.itsvse.com/"
};
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)
