requests.exceptions.JSONDecodeError: Expecting value: line 3 column 1 (char 4)

引用\[1\]中的代码报错是因为在使用`res.json()`解析返回结果时，返回的数据不符合JSON格式，导致解析失败。解决方法是先打印`res.text`查看返回的数据内容，确认是否为完整的JSON数据。\[3\]根据引用\[3\]的解释，你可以通过打印`res.text`来查看返回的数据内容，看看是否完整的JSON数据。如果返回的数据不是完整的JSON格式，那么你需要检查请求的URL和参数是否正确，或者联系API提供方确认数据格式是否正确。
