代码改变世界

调用百度“搜索建议（BaiduSuggestion）”的 API

  音乐让我说  阅读(2500)  评论(1)  编辑  收藏  举报

原理

当前发送一个 Get 请求：http://suggestion.baidu.com/su?wd=wq&p=3&cb=window.bdsug.sug&t=1324271669786

注意 wd：搜索关键字

cb：callback 回调函数

那么百度将返回一个如下的 json 数据：

window.bdsug.sug({q:"wq",p:true,s:["wqvga","wqi","wqsg_umd","wqynyl","wqi下载","wqrc","wqnmlgb","wqvga分辨率","吴奇隆","吾栖之肤"]});

 

其实最复杂的是如何在客户端展示这些数据，需要用到 css 和 js。

正好园子里有朋友做了，感谢！
