Question

我正在将JSONObject转换为String。我使用下面的代码：

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());

这里，我从文件中获取decresponse的值，因为json非常大。响应的价值是：

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

为什么我会得到不同的价值观？

Answer 1

为什么我会得到不同的值

这些值不是不同。他们只是以不同的顺序拥有key:value对。

JSON结构包含key:value对，其中key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）。

在内部调用toString()时，它使用该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。

如果您想保留订单，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", ...这似乎就是你所追求的。

JSONObject未正确转换为String
