【python代码：模拟浏览器访问B站，并下载java相关的视频教程】

帮我写段代码：模拟浏览器访问B站，并下载java相关的视频教程。使用python和go两种方式

Python实现：

import requests
from bs4 import BeautifulSoup
import re
import subprocess# 获取B站Java教程页面的视频链接
url = "=java%E6%95%99%E7%A8%8B&order=click&duration=0&tids_1=0&page=1"
response = requests.get(url)
soup = BeautifulSoup(response.text, "html.parser")
elems = soup.find_all('a', {'class': 'title'})
urls = []
for elem in elems:urls.append("https:"+elem['href'])# 下载视频
for url in urls:response = requests.get(url)soup = BeautifulSoup(response.text, "html.parser")match = re.search(r'"baseUrl":"(.*?)"', str(soup))if match:video_url = match.group(1).replace("\\", "")subprocess.call(["wget", "-O", "video.mp4", video_url])

Go实现：

package mainimport ("fmt""io""net/http""os""regexp"
)func main() {// 获取B站Java教程页面的视频链接resp, _ := http.Get("=java%E6%95%99%E7%A8%8B&order=click&duration=0&tids_1=0&page=1")defer resp.Body.Close()bodyBytes, _ := io.ReadAll(resp.Body)body := string(bodyBytes)re := regexp.MustCompile(`class='title' href='(.*?)' target`)matches := re.FindAllStringSubmatch(body, -1)urls := []string{}for _, match := range matches {urls = append(urls, "https:"+match[1])}// 下载视频for _, url := range urls {resp, _ := http.Get(url)defer resp.Body.Close()bodyBytes, _ := io.ReadAll(resp.Body)body := string(bodyBytes)re := regexp.MustCompile(`"baseUrl":"(.*?)"`)match := re.FindStringSubmatch(body)if len(match) > 0 {video_url := match[1]video_url = regexp.MustCompile(`\\`).ReplaceAllString(video_url, "")f, _ := os.Create("video.mp4")defer f.Close()resp, _ := http.Get(video_url)defer resp.Body.Close()io.Copy(f, resp.Body)fmt.Println("Downloaded video from", url)}}
}
