HttpPost 在 android sdk 23 中不工作

Question

我的 android 应用程序中有一个使用 HttpPost class 的方法。它在目标 sdk 4.4.2 上运行良好，但我进行了一些更改并将目标 sdk 设为 23(6.0)。现在 HttpPost class 出错了。我也读过 HttpUrlConnection 但不知道如何使用它。这是我的 BaseActivity，我在我的其他活动中扩展了这个 class，这在 SDK 4.4.2 中有效，但在 sdk23 中无效，请帮助

public class BaseActivity extends ActionBarActivity {
private Toolbar mToolbar;
private NavigationDrawerFragment mNavigationDrawerFragment;
LayoutInflater inflater;
FrameLayout container;
private static final int socketTimeout = 30000;
private static final int maxTries = 4;
Context context;
ProgressDialog dialog;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}

protected void setBaseContentView(int LayoutId) {
    setContentView(R.layout.drawer_layout);
    mToolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);
    setSupportActionBar(mToolbar);
    getSupportActionBar().setDisplayShowHomeEnabled(true);
    mNavigationDrawerFragment = (NavigationDrawerFragment) getFragmentManager()
            .findFragmentById(R.id.fragment_drawer);
    mNavigationDrawerFragment.setup(R.id.fragment_drawer, (DrawerLayout) findViewById(R.id.drawer), mToolbar);
    container = (FrameLayout) findViewById(R.id.container);
    inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    container.addView(inflater.inflate(LayoutId, null));
}

Answer 1

看看这个：

According to the API 22-23 diff changes, the org.apache.http.* packages have been removed as of Android 6.0 (Marshmallow) API Level 23. -

建议：要么使用遗留代码

android {
       useLibrary 'org.apache.http.legacy'
   }

或更好地使用HttpURLConnection (example)

Answer 2

我目前正在使用 OKHTTP，到目前为止我没有遇到任何问题。它很棒且易于使用。
