收集整理的这篇文章主要介绍了SmartHTTP 简易HttpRequest类(ASP)，觉得挺不错的，现在分享给大家，也给大家做个参考。 最简单的调用方法： response.wrITe SmartHttp("http://www.baidu.COM/").send().gettext()
复杂调用
set myhttp = SmartHttp("http://www.baidu.com/s","GET")
myhttp.dataset.apPEnd "wd","smarthttp"
myhttp.send()
response.write myhttp.gettext("gbk")
复制代码 代码如下:
