comalibabafastjsonJSONException expect at 0 actual = 中文回答

The error message "com.alibaba.fastjson.JSONException: expect ':' at 0, actual = 中文回答" suggests that there is an issue with the JSON syntax. The parser expects a colon (':') at position 0, but instead, it encountered the string "中文回答".

To resolve this issue, you need to ensure that the JSON string you are trying to parse follows the correct syntax. Make sure that each key-value pair is separated by a colon and that the keys are enclosed in double quotes. Additionally, ensure that all values are valid JSON data types (such as strings, numbers, booleans, null, arrays, or objects)
