从 json 推文中获取 json 用户 [英] Get json user from json tweet

问题描述

我有一条已存储在文件中的推文.我想将用户提取为 json 对象并将其存储在不同的文件中.java.lang.IllegalStateException 中的以下结果:显然 jsonStoreEnabled 未设置为 true.

I have a tweet that I had stored in a file. I want to extract the user as a json object and store it in a different file. The following results in java.lang.IllegalStateException: Apparently jsonStoreEnabled is not set to true.

String jsonStatus; //Content read from a file
Status status = TwitterObjectFactory.createStatus(jsonStatus); //no problem here
String jsonUser = TwitterObjectFactory.getRawJSON(status.getUser()); //Exception

如何将 jsonStoreEnabled 设置为 true?或者，还有其他方法吗?我不必坚持使用 Twitter4j 来创建 jsonUser.我尝试了 json-simple，但结果字符串无法用 Twitter4j 解析.

How can I set jsonStoreEnabled to true? Or, is there another way of doing it? I don't have to stick with Twitter4j to create jsonUser. I tried json-simple, but the resulting String is not parsable with Twitter4j.

推荐答案

事实证明 org.json 包在这种情况下很有帮助:

It turns out that the org.json package was helpful in this case:

public static String extractUser(String rawJSON) {
    return new org.json.JSONObject(rawJSON).get("user").toString();
}
