项目地址https://github.com/lixi5338619/magical_spider
使用指南1、配置settings.py，启动flask服务
2、参考demo文件夹中的代码进行测试，主要通过runflow.py运行。
代码语言：javascript代码运行次数：0运行复制```javascript import requestshost = 'http://127.0.0.1:5000'def magical_start(project_name,base_url = 'https://www.php.cn/link/b6f05a7baab2fe0eea07e59bd5b0b317'): # 1、创建浏览器并选择session_id result = requests.post(f'{host}/create',data={'name':project_name,'url':base_url}).json() session_id,process_url = result['session_id'],result['process_url'] return session_id,process_urldef magical_request(session_id,process_url,request_url): # 2、请求浏览器_xhr data = {'session_id':session_id,'process_url':process_url, 'request_url':request_url,'request_type':'get'} result = requests.post(f'{host}/xhr',data=data).json() return result['result']def magical_close(session_id,process_url,process_name): # 4、关闭浏览器 close_data = {'session_id':session_id,'process_url':process_url,'process_name':process_name} requests.post(f'{host}/close',data=close_data).json()
