JSONObject 未正确转换为字符串

Question

我正在将 JSONObject 转换为字符串。我正在使用以下代码：

String decresponse=obj.getFileWithUtil("Files/v3user22.txt");
System.out.println("Decrypted string is "+decresponse);
JSONObject js = JSONObject(decresponse);
System.out.println("JSON Object is "+js.toString());

在这里，由于 json 非常大，我从文件中获取了 decresponse 的值。 decresponse 的值是：

{
    "userid":123456,
    "status":"SUCCESS",
    "name":{
        "firstName":"firstname",
        "lastName":"lastname"

为什么我得到不同的值？

Answer 1

为什么我得到不同的值

这些值并没有那不同。它们只是具有不同顺序的 key:value 对。

JSON 结构包含 key:value 对，其中 keys 是唯一的。在大多数情况下，键的顺序并不重要，因此像org.json.JSONObject 这样的类将它们存储在内部HashMap 中，这不会保留插入顺序（但允许快速访问值）。

当toString() 在内部调用时，它会使用 HashMap 迭代器构建 String，因此顺序取决于键的数量及其哈希值，而不是插入顺序。

如果您想保持顺序，请考虑使用其他库，例如 gson。您的解析可能如下所示：

JsonParser jsonParser = new JsonParser();
JsonObject js = jsonParser.parse(decresponse).getAsJsonObject();

和js.toString() 会导致
{"userid":123456,"status":"SUCCESS","name":{"firstName":"firstname", ... 这似乎是你所追求的。
