组合（合并）两个 JSONObjects 的最佳方法是什么？

What is the best way to combine (merge) two JSONObjects?

JSONObject o1 = {
    "one": "1",
    "two": "2",
    "three": "3"
}
JSONObject o2 = {
        "four": "4",
        "five": "5",
        "six": "6"
    }

结合 o1 和 o2的结果必须

JSONObject result = {
        "one": "1",
        "two": "2",
        "three": "3",
        "four": "4",
        "five": "5",
        "six": "6"
    }

推荐答案

我有同样的问题：我找不到 putAll 方法（它没有在官方参考页）。

I have your same problem: I can't find the putAll method (and it isn't listed in the official reference page).

所以，我不知道如果这是最好的解决方案，但肯定它运作得很好：

So, I don't know if this is the best solution, but surely it works quite well:

//I assume that your two JSONObjects are o1 and o2
JSONObject mergedObj = new JSONObject();

Iterator i1 = o1.keys();
Iterator i2 = o2.keys();
String tmp_key;
while(i1.hasNext()) {
    tmp_key = (String) i1.next();
    mergedObj.put(tmp_key, o1.get(tmp_key));
}
while(i2.hasNext()) {
    tmp_key = (String) i2.next();
    mergedObj.put(tmp_key, o2.get(tmp_key));
}

现在，合并的JSONObject存储在 mergedObj

Now, the merged JSONObject is stored in mergedObj
