使用 gson 从 JsonArray 获取值

Question

I have searched everywhere and cannot find out how to do this, I'm super stuck. I have NO experience with JSON files, so spoon feeding is appreciated along with an explanation.

I have this JSON text here for testing:

    {
      "id":"4566e69fc90748ee8d71d7ba5aa00d20",
      "properties":
                    [
                     {
                      "name":"textures",
                      "value":"eyJ0aW1lc3RhbXAiOjE0ODI4ODAxNDMwNzYsInByb2ZpbGVJZCI6IjQ1NjZlNjlmYzkwNzQ4ZWU4ZDcxZDdiYTVhYTAwZDIwIiwicHJvZmlsZU5hbWUiOiJUaGlua29mZGVhdGgiLCJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvMTNlODFiOWUxOWFiMWVmMTdhOTBjMGFhNGUxMDg1ZmMxM2NkNDdjZWQ1YTdhMWE0OTI4MDNiMzU2MWU0YTE1YiJ9LCJDQVBFIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvMjJiOWM1ZWE3NjNjODZmYzVjYWVhMzNkODJiMGZhNjVhN2MyMjhmZDMyMWJhNTQ3NjZlYTk1YTNkMGI5NzkzIn19fQ==",
                     },
                    ],
      "name":"Thinkofdeath",
    }

I currently have this:

    JsonElement playerProfile = new JsonParser().parse(jsonLine);
    JsonObject jsonProfile = playerProfile.getAsJsonObject();
    JsonArray properties = jsonProfile.getAsJsonArray("properties");

Which returns [

[
  {
    "name":"textures",
    "value":"eyJ0aW1lc3RhbXAiOjE0ODI4ODAxNDMwNzYsInByb2ZpbGVJZCI6IjQ1NjZlNjlmYzkwNzQ4ZWU4ZDcxZDdiYTVhYTAwZDIwIiwicHJvZmlsZU5hbWUiOiJUaGlua29mZGVhdGgiLCJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvMTNlODFiOWUxOWFiMWVmMTdhOTBjMGFhNGUxMDg1ZmMxM2NkNDdjZWQ1YTdhMWE0OTI4MDNiMzU2MWU0YTE1YiJ9LCJDQVBFIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvMjJiOWM1ZWE3NjNjODZmYzVjYWVhMzNkODJiMGZhNjVhN2MyMjhmZDMyMWJhNTQ3NjZlYTk1YTNkMGI5NzkzIn19fQ==",
  },
]

Of course. How do I get the "value" from this JsonArray? Note I'm using Google's API, Gson

Answer 1

You can get values using:

JsonObject propertiesJson = properties.get(0);
String value = propertiesJson.getString("value");

Answer 2

array is JsonArray object from com.google.gson library

for (int i=0; i<array.size(); i++) {
    JsonObject json = array.get(i).getAsJsonObject();
    String value = json.get("key").getAsString();
}
