以下是实现从给定JSON对象中提取`images`、`videos`和`poster`的Java代码： ```java import org.json.JSONArray; import org.json.JSONObject; public class JsonParser { public static void main(String[] args) { String jsonString = "{ \"text\": \"尚敏描述\", \"images\": [\"http://8.130.145.91/file/createActivity/25/06/06/170446_1050nulls1SKnOrA3Jw61573e43389c7a67e00798ada6d2afab9.jpg\"], \"videos\": [{\"src\": \"http://8.130.145.91/file/createActivity/25/06/06/170449_796nullpS3fzv4zUbqgf03b935fa8fc8c98aba7aa2a90b56bfc.mp4\", \"poster\": \"http://8.130.145.91/file/createActivity/25/06/06/170449_881nullGAqCobiEL76o184882bbe368e83787d1f8f4c21d0b78.jpg\"}], \"timestamp\": 1749200694087}"; // 将字符串解析为JSONObject JSONObject jsonObject = new JSONObject(jsonString); // 提取images JSONArray imagesArray = jsonObject.getJSONArray("images"); System.out.println("Images:"); for (int i = 0; i < imagesArray.length(); i++) { System.out.println(imagesArray.getString(i)); } // 提取videos和poster JSONArray videosArray = jsonObject.getJSONArray("videos"); System.out.println("\nVideos and Posters:"); for (int i = 0; i < videosArray.length(); i++) { JSONObject videoObject = videosArray.getJSONObject(i); System.out.println("Video Src: " + videoObject.getString("src")); System.out.println("Poster: " + videoObject.getString("poster")); } } } ``` ### 解释： 1. **JSON解析**：我们使用了`org.json`库来解析JSON字符串。这个库提供了`JSONObject`和`JSONArray`类，方便操作JSON数据。 2. **提取Images**：通过`jsonObject.getJSONArray("images")`获取`images`数组，并遍历输出每个图片链接。 3. **提取Videos和Poster**：通过`jsonObject.getJSONArray("videos")`获取`videos`数组，然后对每个视频对象提取`src`和`poster`字段。 如果需要处理更复杂的JSON结构或更大的数据集，可以考虑使用其他JSON库（如Jackson或Gson）。
