如何用PHP中的curl获取百度地图上的搜索结果数据？百度地图上的数据：http://map.baidu.com/?newmap=1&ie=utf-8&s=s%26wd%3D%E5%81%9C%E8%BD%A6%E5%9C%BA
在firebug中能看到

) 我要用程序来获取到数据源。

Answer 1

我原先的做法：
$curl = curl_init();
// 2. 设置选项，包括URL
curl_setopt($curl, CURLOPT_URL, "http://map.baidu.com/?newmap=1&ie=utf-8&s=s%26wd%3D%E5%81%9C%E8%BD%A6%E5%9C%BA");
curl_setopt($curl, CURLOPT_HEADER, 0);curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);// 3. 执行并获取HTML文档内容
$output = curl_exec($curl);
// 4. 释放curl句柄
curl_close($curl);
echo $output;运行的结果：页面上地图没有加载进来，打开IE中的查看源代码，那些数据源<script>标签内的东西也没有获取到

Answer 2

真心研究了好久，还是没成功，而且百度提供的API也不行，不过google的地图API倒是可以实现只获取数据（xml、json都支持）。

Answer 3

google的有API，可以直接发送http获得相应数据，不像百度的直接调用它们的js，google的话可以获得相应数据。http://code.google.com/intl/zh-CN/apis/maps/documentation/mapsdata/developers_guide_protocol.html
还有一个google的curl调用http://code.google.com/intl/zh-CN/apis/gdata/articles/using_cURL.html
