Question

我正在尝试登录并注册我的Android应用程序。我遇到了HttpParams的问题。我正在关注Tonikami的Youtube教程。我刚刚使用Android Studio。这只是我所知道的过程。非常感谢您的帮助。：（

public class ServerRequests {
ProgressDialog progressDialog;
public static final int CONNECTION_TIMEOUT = 1000 * 15;
public static final String SERVER_ADDRESS = "http://mywebsite.com/";

public ServerRequests(Context context) {
    progressDialog = new ProgressDialog(context);
    progressDialog.setCancelable(false);
    progressDialog.setTitle("Processing...");
    progressDialog.setMessage("Please wait...");
}

public void storeUserDataInBackground(User user, GetUserCallback userCallBack) {
    progressDialog.show();
    new StoreUserDataAsyncTask(user, userCallBack).execute();
}

public void fetchUserDataAsyncTask(User user, GetUserCallback userCallBack) {
    progressDialog.show();
    new fetchUserDataAsyncTask(user, userCallBack).execute();
}

public class StoreUserDataAsyncTask extends AsyncTask<Void, Void, Void> {
    User user;
    GetUserCallback userCallBack;

    public StoreUserDataAsyncTask(User user, GetUserCallback userCallBack) {
        this.user = user;
        this.userCallBack = userCallBack;
    }

    @Override
    protected Void doInBackground(Void... params) {
        ArrayList<NameValuePair> dataToSend = new ArrayList<>();
        dataToSend.add(new BasicNameValuePair("name", user.name));

Answer 1

URL url = new URL("http://google.co.in");
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("POST");
            conn.setConnectTimeout(2000);
           is = conn.getInputStream();

使用上述代码代替折旧的httpParams

对于传递post params，请这样做

 Uri.Builder builder = new Uri.Builder();
    builder.appendQueryParameter("param1", "paramvalue1");
            builder.appendQueryParameter("param2", "paramvalue2");

String query = builder.build().getEncodedQuery();
            OutputStream os = conn.getOutputStream();
            BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(os, "UTF-8"));
            writer.write(query);
            writer.flush();
            writer.close();
            os.close();
            conn.connect();
            is = conn.getInputStream();

HttpParams已弃用。我该怎么办？
