您可以使用Python中的urllib.request.add_header方法来设置请求头中的Content-type为application/json。这个方法可以在发送请求之前使用,将Content-type设置为您需要的值。例如,您可以使用以下代码来设置Content-type为application/json:
```python
import urllib.request
req = urllib.request.Request(url)
req.add_header('Content-type', 'application/json')
```
这样,当您发送请求时,请求头中的Content-type就会被设置为application/json。这样可以确保您发送的请求被正确地解析为JSON格式。\[3\]
