Python数据抓取报错：requests.exceptions.InvalidSchema问题求助

问题根源 #

报错核心原因是请求URL的协议部分拼写错误：htttps://多了一个t，正确协议应为https://。

修正方案 #

打开路径c:\Users\LZ\Desktop\py.data fatching\datafatching.py的脚本，将第3行的请求代码修改为：

response = requests.get("https://jsonplaceholder.typicode.com/posts")

错误说明 #

requests库仅支持标准的网络协议前缀，当传入错误的htttps://时，库无法识别该协议，因此抛出InvalidSchema异常，提示"No connection adapters were found for 'htttps://...'"——即找不到对应错误协议的连接适配器来处理请求。
