在VBS里面的调用方法
dim myhttp
set myhttp = SmartHttp(url,method,data); //三个参数均可选
属性：
url：String，请求的URL地址
method：String，请求的方法
data：String，请求的数据
charset：String，请求的URL返回数据的编码
status：Int，请求返回的状态码
readyState：Int，同HTTP请求的当前通讯状态，1、2、3、4
dataset：Object，请求的数据，如果增加了，会将这部分数据附加到data属性
dataset属性：
charset：String，发送数据的编码
dataset方法：
append(key,value,noencode)：添加数据
remove(key)：移除某个数据项
isexists(key)：判断某个数据项是不是存在
clear：清除所有数据项
方法：
header(headstr)：设置请求头，项和值之间用:分开
timeout(t1,t2,t3,t4)：设置超时时间
send()：发送请求
getbinary：获取服务器返回的二进制数据
gettext(charset)：获取指定编码的文本
getjson(charset)：获取指定编码的json数据
getheader(key)：获取服务器返回的响应头
getxml(charset)：获取指定编码的xml数据
