我如何使用简单的HTTP客户端在Android中？

问题描述

我如何使用 AndroidHttpClient 作为HTTP客户端连接到远程服务器？我一直没能找到的文件，也没有在互联网上很好的例子。

解决方案

 公共静态无效连接（字符串URL）
{

    HttpClient的HttpClient的=新DefaultHttpClient（）;

    // prepare请求对象
    HTTPGET HTTPGET =新HTTPGET（URL）;

    //执行请求
    HTT presponse响应;
    尝试 {
        响应= httpclient.execute（HTTPGET）;
        //检查响应状态
        Log.i（Praeda，response.getStatusLine（）的toString（））;

        //弄个响应实体
        HttpEntity实体= response.getEntity（）;
        //如果响应不围绕的实体，也没有必要
        //担心连接释放

        如果（实体！= NULL）{

            //一个简单的JSON响应读取
            InputStream的河道= entity.getContent（）;
            字符串结果= convertStreamToString（河道）;
            //现在你有串重的HTML请求presentation
            instream.close（）;
        }


    }赶上（例外五）{}
}

    私有静态字符串convertStreamToString（InputStream的是）{
    / *
     *要InputStream中转换为字符串，我们使用使用BufferedReader.readLine（）
     * 方法。我们迭代直到BufferedReader中返回NULL，这意味着
     *没有更多的数据读取。每个行会附加到一个StringBuilder
     *和返回的字符串。
     * /
    的BufferedReader读卡器=新的BufferedReader（新InputStreamReader的（是））;
    StringBuilder的SB =新的StringBuilder（）;

    串线= NULL;
    尝试 {
        而（（行= reader.readLine（））！= NULL）{
            sb.append（行+\ N）;
        }
    }赶上（IOException异常E）{
        e.printStackTrace（）;
    } 最后 {
        尝试 {
            is.close（）;
        }赶上（IOException异常E）{
            e.printStackTrace（）;
        }
    }
    返回sb.toString（）;
}
 

How do I use the AndroidHttpClient as an HTTP client to connect to a remote server? I have not been able to find good examples in the documentation nor on the internet.

解决方案

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
        Log.i("Praeda",response.getStatusLine().toString());

        // 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();
}
