一 GET

String path = "http://v.juhe.cn/toutiao/index"; //接口地址String parameter = "?type=&key=***"; //请求参数try {    HttpClient client = new DefaultHttpClient(); //"客户端"    HttpGet get = new HttpGet(path + parameter);//get方式请求参数    HttpResponse response = client.execute(get);    if(response.getStatusLine().getStatusCode() == 200) { //获取链接状态        InputStream is = response.getEntity().getContent();  //获取输入流        String data = StreamTool.decodeStream(is);  //StreamTool 代码附加在最后，用来把二进制流转换为字符流        JSONObject jsonObject = new JSONObject(data);  //解析JSON格式数据        if("成功的返回".equals(jsonObject.getString("reason"))) {            JSONObject dataObject = jsonObject.getJSONObject("result");            JSONArray jsonArray = dataObject.getJSONArray("data");            Message msg = Message.obtain();            msg.obj = jsonArray;            msg.what = SECCESS;            mHandler.sendMessage(msg);        }else{            Message msg = Message.obtain();            msg.what = DATA_ERRER;            mHandler.sendMessage(msg);        }    }else{        Message msg = Message.obtain();        msg.what = CONNECT_ERRER;        mHandler.sendMessage(msg);    }} catch (Exception e) {    Message msg = Message.obtain();    msg.what = ERRER;    mHandler.sendMessage(msg);    e.printStackTrace();}

二 POST
在设置数据实体部分有些绕，需要理解记忆
参数key涉及个人隐私，所以用 ** 代替

String path = "http://v.juhe.cn/toutiao/index"; //接口地址try {    HttpClient client = new DefaultHttpClient();// HttpClient是一个抽象类，new时需注意    HttpPost post = new HttpPost(path); //post请求方式    参数为接口地址    //设置 数据 实体                  List<NameValuePair> parameters = new ArrayList<NameValuePair>();    parameters.add(new BasicNameValuePair("type", ""));    parameters.add(new BasicNameValuePair("key", "***"));    post.setEntity(new UrlEncodedFormEntity(parameters));    HttpResponse response = client.execute(post);    if(response.getStatusLine().getStatusCode() == 200){        InputStream is = response.getEntity().getContent();        String data = StreamTool.decodeStream(is);  //StreamTool 代码附加在最后，用来把二进制流转换为字符流        JSONObject jsonObject = new JSONObject(data);  //解析JSON格式数据        if("成功的返回".equals(jsonObject.getString("reason"))) {            JSONObject dataObject = jsonObject.getJSONObject("result");            JSONArray jsonArray = dataObject.getJSONArray("data");            Message msg = Message.obtain();            msg.obj = jsonArray;            msg.what = SECCESS;            mHandler.sendMessage(msg);        }else{            Message msg = Message.obtain();            msg.what = DATA_ERRER;            mHandler.sendMessage(msg);        }    }else{        Message msg = Message.obtain();        msg.what = CONNECT_ERRER;        mHandler.sendMessage(msg);    }} catch (Exception e) {    Message msg = Message.obtain();    msg.what = ERRER;    mHandler.sendMessage(msg);    e.printStackTrace();}

附加：StreamTool 类

public class StreamTool {    public static String decodeStream(InputStream is) throws IOException {        ByteArrayOutputStream bout = new ByteArrayOutputStream();        int len = 0;        byte[] buffer = new byte[1024];        while((len = is.read(buffer))>0) {            bout.write(buffer, 0, len);        }        String data = bout.toString();        return data;    }}
