HttpClientHelper

这个主要用于WebApi和MVC进行交互桥梁的一种方法

public class HttpClientHelper
{
      
	public HttpClientHelper(string baseAddr)
	{

	}
	public  string BaseAddr {

	     	//设置 默认请求头ACCEPT

	     	//发送GET请求
	     	HttpResponseMessage msg =  client.GetAsync(Url).Result;
	     	//判断结果是否成功
	     	if (msg.IsSuccessStatusCode)
