如何实现后台发送网址然后获取返回网址？
有没有办法在后台不使用浏览器情况下给服务器发送网址，然后获取返回的网址？第一次发问，不知道这能不能实现？{:face (245):} 回复 1# zxk123
用TCP或UDP之类的，但前提是服务器会接收你的数据包，并且返回信息。 本帖最后由 zxk123 于 2011-10-25 09:28 编辑
控制台程序main.cpp如下（这个例子是参考来的，一些地方进行了修改）

在本地服务器localhost启动apache服务器，在对应的文档目录下放上test1.php文件，此服务器文件如下：
<html>
<head></head>
<body>
<?php
echo 'strlen(str) * num = ' . strlen($_GET['str']) * $_GET['num'];
?>
</body>
</html>
这段代码是网上找到的，不是AU3的看不懂，求大神分析下。 上面是C++的嘛 本帖最后由 happytc 于 2011-10-25 10:32 编辑

你在那里拷的乱78糟的cpp文件。
你是这个意思呀，参见‘获取网络文件修改时间’的6楼例子
http://www.autoitx.com/forum.php?mod=viewthread&tid=28036&highlight=%CD%F8%C2%E7%CE%C4%BC%FE
另外参见republican的_WinHTTP_GetRespond
http://www.autoitx.com/thread-18528-1-1.html 可以在后台下载找开然后再获取的,仔细看下帮助文件!
