如何在 Java 中使用 themoviedb.org api

Question

我正在使用 themovidedb.org api 在 Java 程序中获取电影信息。

这是我在 link 我的 themovidedb.org 应用程序中使用的函数：

        url = new URL("http://api.themoviedb.org/3/movie/550?api_key={MY_API_KEY}");
        HttpURLConnection con = (HttpURLConnection) url.openConnection();

        con.setDoOutput(true);
        con.setRequestMethod("GET");
        con.setRequestProperty("Content-Type", "application/json");

        BufferedReader br = new BufferedReader(new InputStreamReader((con.getInputStream())));

        String output;
        System.out.println("Output from Server .... \n");
        while ((output = br.readLine()) != null) {
            System.out.println(output);
        }

这是控制台中的响应：

{"adult":false,"backdrop_path":"/87hTDiay2N2qWyX4Ds7ybXi9h8I.jpg","belongs_to_collection":null,"budget":63000000,"genres":[{"id":18,"name":"Drama"}],"homepage":"http://www.foxmovies.com/movies/fight-club","id":550,"imdb_id":"tt0137523","original_language":"en","original_title":"Fight Club","overview":"A ticking-time-bomb insomniac and a slippery soap salesman channel primal male aggression into a shocking new form of therapy.

如何解析响应以获取任何属性（例如：'original_title'、'relase-date'）并在代码中使用它？

是否存在另一种方法 link 程序到数据库（例如使用 WebResource class）？

Answer 1

结果使用 JSON 格式化。有很多 Java 库可以用来解析它。 built-in method for Java EE uses JsonObject.

JsonReader rdr = Json.createReader(con.getInputStream());
JsonObject obj = rdr.readObject();
String title = obj.getString("original_title");

在 Android，你有 JSONObject。

StringBuilder responseStrBuilder = new StringBuilder();

String inputStr;
while ((inputStr = br.readLine()) != null)
    responseStrBuilder.append(inputStr);
JSONObject obj = new JSONObject(responseStrBuilder.toString());
String title = obj.getString("original_title");

如果您有其他要求，还有许多其他库可以执行此操作。还有一些 HTTP 库可以很容易地获得 JSON，比如 Volley for Android:

JsonObjectRequest jsObjRequest = new JsonObjectRequest
        (Request.Method.GET, "http://api.themoviedb.org/3/movie/550?api_key={MY_API_KEY}", null, new Response.Listener<JSONObject>() {

    @Override
    public void onResponse(JSONObject response) {
        System.out("title: " + response.getString("original_title"));
    }
}, new Response.ErrorListener() {

    @Override
    public void onErrorResponse(VolleyError error) {
        // TODO Auto-generated method stub

    }
});

Answer 2

创建一些变量来收集 json 响应并解析它。

var resp = JSON.stringify(output)
var original_title = JSON.parse(resp).original_title
var release_date = JSON.parse(resp).release_date
