可以使用以下代码来解析JSON数据并获取topic的值： ```python import json json_data = '{"data":[{"node":"emqx@127.0.0.1","topic":"4e4a3668bf514c6f89738c5f3eec6285"},{"node":"emqx@127.0.0.1","topic":"05f170438ab44d769f9f67c1406316c2"},{"node":"emqx@127.0.0.1","topic":"fcef086b0ea443429cc867a35fb630fd"},{"node":"emqx@127.0.0.1","topic":"topic_aaa"}],"meta":{"count":4,"hasnext":false,"limit":20,"page":1}}' data = json.loads(json_data) topics = [d['topic'] for d in data['data']] print(topics) ``` 输出结果为： ``` ['4e4a3668bf514c6f89738c5f3eec6285', '05f170438ab44d769f9f67c1406316c2', 'fcef086b0ea443429cc867a35fb630fd', 'topic_aaa'] ```
