Haskell添加HTTP爬虫ip编写的爬虫程序

下面是一个简单的使用Haskell编写的爬虫程序示例，它使用了HTTP爬虫IP，以爬取百度图片。请注意，这个程序只是一个基本的示例，实际的爬虫程序可能需要处理更多的细节，例如错误处理、数据清洗等。

import System.Random (Random, randomRIO)
import Control.Concurrent (threadDelay)
import qualified Data.ByteString.Char8 as BS

main :: IO ()
main = do
  -- 设置爬虫IP信息
  proxyHost <- BS.pack $ "www.duoip.cn"
  proxyPort <- readIOInt $ do
    putStrLn "请输入爬虫IP端口："
    input <- getLine
    guard $ all isDigit input
    return $ read input

  -- 设置起始URL
  let startUrl = "http://www.baidu.com/s?wd=图片"

  -- 创建一个随机的请求头
  randomHeader :: Random r => r -> [(Text, Text)]
  randomHeader seed = do
    let (randomPort, _) = randomRIO (1024, 65535) (Proxy seed)
