Question

开发我的第一个基本的Android应用程序，下面是我打开连接的方式，它运行良好。

URL url = new URL("http://www.mocky.io/v2/568e3d730f0000da3fd1831b");
HttpURLConnection con = (HttpURLConnection) url.openConnection();

现在，如何在此连接上发送数据或json对象？这只是打开一个连接，来验证？验证码是在打开连接之前还是如何工作？

感谢。

此致

如果您要以Api Get

发送数据

String loginUrl = getString(R.string.loginapi) + "emailid=" + emailIdEditText.getText().toString().trim() + "&password=" + passwordEditText.getText().toString().trim();

 sendGet(loginUrl); //TODO:Use Async Task to execute these kind of operations

 // HTTP GET request
    public String sendGet(String apiUrl) {
        StringBuilder result = new StringBuilder();
        HttpURLConnection urlConnection = null;
        try {
            URL url = new URL(apiUrl);
            urlConnection = (HttpURLConnection) url.openConnection();
            InputStream in = new BufferedInputStream(urlConnection.getInputStream());
            BufferedReader reader = new BufferedReader(new InputStreamReader(in));
            String line;
            while ((line = reader.readLine()) != null) {
                result.append(line);
            }

        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            urlConnection.disconnect();
        }
        return result.toString();
    }

如果要将JSON字符串发送到URL，请按照步骤操作创建模型，为对象赋值。使用GSON库将对象转换为字符串（推荐）

GsonBuilder gsonb = new GsonBuilder();
        Gson gson = gsonb.create();
        String regString = gson.toJson(--Object--);
        String createTeamURL = getString(R.string.createTeamapi);

Android studio，如何通过http发送数据？
