适用于我的 PC 的 Android HttpClient

Question

我需要在 org.apache.httpclient 之上为我的 android 应用程序开发一个帮助程序类。以下代码适用于 android，但不适用于我的 PC 中的 JavaSE 1.6。

问题是：我可以在 Android 和 PC 上使用 org.apache.httpclient 吗？如果我不能：你的 http 客户端库有什么建议？ 我想开发一个辅助类并使用它。

下面的代码在 android 中运行良好，但某些类无法在 Java SE 1.6 上解析。

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

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;

public class HTTPClient {

public static void connect(String url)
{

    HttpClient httpclient = new DefaultHttpClient();

    // Prepare a request object
    HttpGet httpget = new HttpGet(url); 

    // Execute the request
    HttpResponse response;
    try {
        response = httpclient.execute(httpget);

        // Examine the response status

        // Get hold of the response entity
        HttpEntity entity = response.getEntity();
        // If the response does not enclose an entity, there is no need
        // to worry about connection release

        if (entity != null) {

            // A Simple JSON Response Read
            InputStream instream = entity.getContent();

            String result= convertStreamToString(instream);
            // now you have the string representation of the HTML request
            instream.close();
        }


    } catch (Exception e) {}
}

    private static String convertStreamToString(InputStream is) {
    /*
     * To convert the InputStream to String we use the BufferedReader.readLine()
     * method. We iterate until the BufferedReader return null which means
     * there's no more data to read. Each line will appended to a StringBuilder
     * and returned as String.
     */
    BufferedReader reader = new BufferedReader(new InputStreamReader(is));
    StringBuilder sb = new StringBuilder();

    String line = null;
    try {
        while ((line = reader.readLine()) != null) {
            sb.append(line + "\n");
        }
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        try {
            is.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    return sb.toString();
}
}

是的，您可以，您应该避免将客户端帮助程序类命名为与已定义的类相同的名称。尽管 Java 区分大小写，但它会在您最意想不到的时候让您感到困惑。它甚至可能因造成这个问题而感到内疚。为什么不将其称为 HttpClientHelper，因为这才是它的真正含义。
