百度不仅是一个搜索工具，而且百度的学习资源也是非常的齐全。今天我要给大家分享的是使用luasocket-http库的Lua编写的一个百度采集程序，主要用于采集百度的相关视频。想要学习的朋友可以来看一下。
```lua-- 引入所需的库local http = require("luasocket.http")local ltn12 = require("ltn12")-- 获取代理服务器local function get_proxy()local proxy_url = "https://www.duoip.cn/get_proxy"local response, code = http.request(proxy_url)if code ~= 200 thenprint("Error: Unable to fetch proxy server.")return nilendlocal data = response:read_all()local proxy = json.decode(data)return proxy.ip .. ":" .. proxy.portend-- 下载视频local function download_video(url, output_file)local proxy = get_proxy()local headers = {["User-Agent"] = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36",["Accept"] = "*/*",["Accept-Language"] = "zh-CN,zh;q=0.8,en;q=0.6,la;q=0.4",["Accept-Encoding"] = "gzip, deflate, br",["Connection"] = "keep-alive",["Proxy-Connection"] = "keep-alive",["Host"] = "www.baidu.com",["Referer"] = "http://www.baidu.com",["Cookie"] = "xxx"}local request_url = urllocal response, code = http.request(request_url, {method = "GET",headers = headers,proxy = proxy,sink = ltn12.sink.file(output_file)})if code ~= 200 thenprint("Error: Unable to download video.")endend-- 主函数local function main()local url = "https://www.baidu.com/xxx" -- 请将此处替换为您想要下载的视频链接local output_file = "output.mp4" -- 保存下载的视频文件download_video(url, output_file)endmain()```
以上代码中，我们需要将`xxx`替换您想要下载的视频链接，并确保已经安装了luasocket和ltn12库，然后就可以直接采集下载了，希望今天的内容能对大家有所帮助。
