OKHTTP の単純な通信の場合

okhttp ネットワーク通信は使用が簡単で、トークンを送信します。これに基づいて、それ自体をカプセル化できます。この記事では、単純で完全なケースとサンプル コードのみを提供します

への呼び出しを提供するパブリック クラス メソッドを作成します。

import okhttp3.MediaType;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;
import org.json.JSONException;
import org.json.JSONObject;

import java.io.IOException;

public class JsonRequestSender {
    
    
    private static final MediaType JSON = MediaType.parse("application/json; charset=utf-8");
    private OkHttpClient client;

    public JsonRequestSender() {
    
    
        client = new OkHttpClient();
    }

    public void sendJsonRequest(String url, JSONObject jsonBody, String token, Callback callback) {
    
    
        RequestBody requestBody = RequestBody.create(JSON, jsonBody.toString());

        Request request = new Request.Builder()
                .url(url)
                .post(requestBody)
                .addHeader("Authorization", "Bearer " + token)
                .build();

        client.newCall(request).enqueue(new okhttp3.Callback() {
    
    
            @Override
            public void onFailure(Call call, IOException e) {
    
    
                if (callback != null) {
    
    
                    callback.onFailure(e);
                }
            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
    
    
                if (callback != null) {
    
    
                    callback.onResponse(response);
                }
            }
        });
    }

    public interface Callback {
    
    
        void onFailure(IOException e);
        void onResponse(Response response) throws IOException, JSONException;
    }
}

説明書

JSONObject jsonBody = new JSONObject();
try {
    
    
    jsonBody.put("key1", "value1");
    jsonBody.put("key2", "value2");
} catch (JSONException e) {
    
    
    e.printStackTrace();
}

String token = "your_token_here";

JsonRequestSender jsonRequestSender = new JsonRequestSender();
jsonRequestSender.sendJsonRequest("https://example.com/api", jsonBody, token, new JsonRequestSender.Callback() {
    
    
    @Override
    public void onFailure(IOException e) {
    
    
        // 请求失败处理逻辑
    }

    @Override
    public void onResponse(Response response) throws IOException, JSONException {
    
    
        // 处理响应结果逻辑
        String responseData = response.body().string();
        JSONObject responseObject = new JSONObject(responseData);
        // ...
    }
});
