clash节点自动切换

为了防止一个IP地址访问频率过快问题，自动切换clash的节点

python 复制代码

def change_node(is_stop):
    while True:
        _r = requests.get("http://127.0.0.1:11053/proxies", headers=clash_headers, verify=False)
        # 这里匹配Lv开头的节点
        proxy_list = [proxy for proxy in _r.json()["proxies"]["XXX"]["all"] if proxy.startswith("Lv")]

        proxy = random.choice(proxy_list)

        payload = json.dumps({"name": proxy})
		# XXX替换为自己的分组名称
        requests.put("http://127.0.0.1:11053/proxies/XXX", headers=clash_headers, data=payload, verify=False)

        time.sleep(5)
        if is_stop.value:
            print("Finished.")
            break

多进程爬虫

get_tile：用于爬取瓦片
write_to_db：用于写入数据库
change_node：用于切换clash节点

python 复制代码

def main():
    is_stop = multiprocessing.Value("I", 0)

    db_path, db_name, tile_list = init_db()
    total = len(tile_list)
    print(total)

    # 创建任务队列
    data_queue = Queue()

    process_list = []
    p_number = 10
    step = total // p_number + 1
    for i in range(p_number + 1):
        process_list.append(
            Process(target=get_tile, args=(data_queue, db_path, db_name, tile_list[i * step:(i + 1) * step],)))

    process_list.append(Process(target=write_to_db, args=(data_queue, db_path, total, is_stop)))

    process_list.append(Process(target=change_node, args=(is_stop,)))

    for p in process_list:
        p.start()

    for p in process_list:
        p.join()
