Java Android-相当于Apache弃用类

我正试图找到下面代码的等价物，因为有些类已被弃用

try
    {
        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(url);
        HttpResponse httpResponse = httpClient.execute(httpPost);
        HttpEntity httpEntity = httpResponse.getEntity();
        is = httpEntity.getContent();
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }

到目前为止，我已经写了这个，但它不工作

HttpURLConnection httpUrlConnection = null;
    try
    {
        URL mUrl = new URL(url);
        httpUrlConnection = (HttpURLConnection) mUrl.openConnection();
        httpUrlConnection.setRequestMethod("POST");
        httpUrlConnection.connect();
        is = new BufferedInputStream(httpUrlConnection.getInputStream());
        httpUrlConnection.disconnect();
    }
catch(Exception e)
{
    e.printStackTrace();
}

在请求之后，我得到了一个异常，因此我认为我的请求有问题。

您可以使用apache遗留库。在Build.grade顶级文件中放置以下行

buildscript {
    ...
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.1'
    }
}

以下是应用程序级build.gradle：

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.0"
    useLibrary 'org.apache.http.legacy'
    ...
}

httpUrlConnection.disconnect（）断开连接后，您认为inputstream会发生什么变化？
