Requests 中有一个内置的 JSON 解码器 response.json(),处理返回的 JSON 数据。使用后,会把返回的数据 作为一个python中的json数据对象看待。如果 JSON 解码失败, response.json() 就会抛出一个异常。 url = 'https://api.weixin.qq.com/cgi-bin/token' data = {'grant_type':'client_credential', 'appid...

response = requests.get("http://httpbin.org/get",params=data) print(response.text) 3.解析json Json用来保存一些键值对组成的数据,用于数据交换,也可用于前后端之间互相传递数据,比如前端发起请求,调用接口,后端返回一串json数据,处理数据,渲染到页面上。
response = requests.get(url) time.sleep(1) # 固定延迟1秒 优点:实现简单,适用于低频率爬取。缺点: 如果目标网站允许更快的请求,固定延迟会降低爬取效率。 如果目标网站检测到固定间隔请求,可能触发反爬机制。 1.2 动态延迟 动态延迟根据网站响应、请求频率等因素调整等待时间,例如: ...
