Question

我正在创建一个CMS应用程序，我正在尝试创建一个JSON对象，我可以发布到我的API，但我不知道如何做到这一点，因为我是新的Android。有没有人有想法？

我的代码：

String URL = "http://test.soundwave.drieo.nl/api/content/" + uid + "?apikey=aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa";

    try {
        APIClientJSONObject api = new APIClientJSONObject();
        JSONObject result = null;

        try {
            result = api.execute(URL).get();
        } catch (Exception e) {
            e.printStackTrace();
        }

            try {

                String content = result.optString("FormattedName");
                String content2 = result.optString("Title");
                String content3 = result.optString("Subtitle");
                String content4 = result.optString("Text");

                EditText name = (EditText) findViewById(R.id.etInternNaam);
                name.setText(content);
                EditText titel = (EditText) findViewById(R.id.etName);
                titel.setText(content2);
                EditText ondertitel = (EditText) findViewById(R.id.etOndertitel);
                ondertitel.setText(content3);
                EditText EditText = (EditText) findViewById(R.id.etTekst);
                EditText.setText(Html.fromHtml(content4));

                if("null" == content) {
                    name.setText("");
                }
                if("null" == content2) {
                    titel.setText("");
                }
                if("null" == content3) {
                    ondertitel.setText("");
                }
                if("null" == content4) {
                    EditText.setText("");
                }

            } catch (Exception e) {
                e.printStackTrace();
            }

API代码：

package nl.drieo.soundwave.test.cms;

import android.os.AsyncTask;

import org.json.JSONObject;

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;

import cz.msebera.android.httpclient.HttpResponse;
import cz.msebera.android.httpclient.client.HttpClient;
import cz.msebera.android.httpclient.client.methods.HttpGet;
import cz.msebera.android.httpclient.impl.client.DefaultHttpClient;

/**
 * Created by r.devries on 14-3-2016.
*/
public class APIClientJSONObject extends AsyncTask<String, Void, JSONObject>           {

@Override
protected JSONObject doInBackground(String... params) {

    JSONObject result = null;

    try {
        HttpClient httpclient = new DefaultHttpClient();
        HttpResponse httpResponse = httpclient.execute(new HttpGet(params[0]));
        InputStream inputStream = httpResponse.getEntity().getContent();
        BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
        StringBuilder builder = new StringBuilder();

        String line = null;

        while ((line = reader.readLine()) != null) {
            builder.append(line);
        }
        result = new JSONObject(builder.toString());
    }
    catch (Exception e) {
        e.printStackTrace();
    }

    return result;
}

}

您可以像这样创建JSONObject并将数据放入其中：

将数据放到json后，可以通过这种方式将json传递给'APIClientJSONObject'类：
编辑：将此代码用于按钮的OnClickListener

JSONObject json = new JSONObject();
json.put("user", "example");

你可以像这样在'APIClientJSONObject'类中获取Json：

try {
        result = api.execute(URL,json.toString()).get();
    } catch (Exception e) {
        e.printStackTrace();
    }

或者如果你想将这个json'POST'到webservice，你可以使用：
编辑：将它用于doInBackground方法中的 APIClientJSONObject 类：

JSONObject jsonObject = new JSONObject(params[1])

我希望这些代码对您有用。
