Python+selenium批量下载微信公众号内的文字和图片

lzmomo

初学python，希望大家多提议意见运行程序，输入网址，运行后会在path/to/save/路径下载文本和图片，文本以txt保存，文件名按照标题名称生成。
requests可以直接下载图片，但是不知道怎么下载文本，谁能教教我吗

知心

response.text这是返回的文本对象，然后用write写入到文件就行。注意下编码问题

SMRC86

要在Python中保存文本，你可以使用以下代码：

```python
with open("文件名.txt", "w", encoding="utf-8") as f:
    f.write("要保存的文本内容")
```

将"文件名.txt"替换为你想要保存的文件名，将"要保存的文本内容"替换为你想要保存的文本。
