如何实现后台发送网址然后获取返回网址？

zxk123

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？

    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。

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）

#define BUF_SIZE 4096

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

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 ... 8%C2%E7%CE%C4%BC%FE

另外参见republican的_WinHTTP_GetRespond
