关于爬取百度搜索结果的问题-百度快照爬虫

疫情期间写了一个代码用request爬取百度搜索的内容，但是过了2个月突然发现不行了，老是需要进行验证。应该是识别到我是爬虫，是否近期百度对于爬虫的验证有所加强，通过伪装agent和配置代理IP好像都不行。有没有哪位大神可以支支招。

agent伪装：

         lifeProxies=GetIpLive5()
                #获取代理IP的代码        
        ua = UserAgent()
        if proxies.get('http')!=None:        
        #print(proxies.get('http'))
            proxy_support = urllib.request.ProxyHandler(proxies)  #也可以设置为https，要看你的代理支不支持
            opener = urllib.request.build_opener(proxy_support)

        else:
            opener = urllib.request.build_opener()

        opener.addheaders = [

                         ('Host', 'www.baidu.com'),

        urllib.request.install_opener(opener)
        while True:
            try:
            #response = opener.open(url)
                time.sleep(3+random.randint(1,8))

                url=urllib.parse.quote(url, safe=string.printable)

                req = urllib.request.Request(url)
            #response = urllib.request.urlopen(url)
                response = opener.open(req)
                break
            except Exception as e:
                print("错误信息：" + str(e))
                time.sleep(3)

        backurl=response.geturl()

        response=gzip.GzipFile(fileobj=response)

        html = response.read().decode("utf-8")

打印出来的代理格式：
当前代理验证成功:{'http': 'http://61.135.185.90:80/'}

版主有熟悉的稳定又便宜的高匿名代理推荐么？麻烦推荐一下哈。

服务器有验证，针对的是ip，你需要换ip或者用高匿名代理。
