[android]代码库
方法一：HttpURLConnection  GET请求
////////////////////////////////////////////////////////////
private void getdata() {
        dialog = new ProgressDialog(getActivity());
        dialog.setMessage("正在加载...");
        dialog.show();
        new  Thread() {
 
            public void run() {
                // android4.0之后,耗时操作放在子线程里
                URL url;
                try {
                    url = new URL("http://v.juhe.cn/weixin/query?key=484057f2721591bc4730f6b370c7ff31&pno="+num);
                     try {
                        HttpURLConnection connection=(HttpURLConnection) url.openConnection();
                        //连接时间
                        connection.setConnectTimeout(5000);
                        //读取时间
                        connection.setReadTimeout(5000);
                        //获取请求码
                        int code = connection.getResponseCode();
                        //请求码为200即成功
                        if(code==200){
                            //转换成字节流
                            InputStream inputStream = connection.getInputStream();
                            //字节数组输出流
                            ByteArrayOutputStream byteArrayOutputStream=new ByteArrayOutputStream();
                            byte[] b=new byte[1024];
                            int len=0;
                            //循环读取
                            while((len=inputStream.read(b))!=-1){
                                //写入字节数组
                                byteArrayOutputStream.write(b, 0, len);
                            }
                            //转换成字符串
                            String string = byteArrayOutputStream.toString("utf-8");
                            //解析
                            Gson gson=new Gson();
                            Bean bean = gson.fromJson(string, Bean.class);                  
                            //发送消息
                            handler.obtainMessage(0, bean).sendToTarget();
                        }
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                } catch (MalformedURLException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }           
            };
        }.start();
    }
方法二：HttpURLConnection  POST请求             耗时操作放在线程中
////////////////////////////////////////////////////////
//请求路径
            URL url=new URL("http://v.juhe.cn/weixin/query?");
//获取HttpURLConnection 
            HttpURLConnection httpURLConnection=(HttpURLConnection) url.openConnection();
//请求方式
            httpURLConnection.setRequestMethod("POST");
//连接读取耗时
            httpURLConnection.setConnectTimeout(5000);
            httpURLConnection.setReadTimeout(5000);
//将参数写入
            String str="key=484057f2721591bc4730f6b370c7ff31&pno="+num;
            httpURLConnection.setDoOutput(true);
            OutputStream outputStream = httpURLConnection.getOutputStream();
            outputStream.write(str.getBytes());
//请求码
            int code = httpURLConnection.getResponseCode();
            if(code==200){
                InputStream inputStream = httpURLConnection.getInputStream();
                BufferedReader reader=new BufferedReader(new InputStreamReader(inputStream));
                String s=null;
                StringBuilder builder=new StringBuilder();
                while((s=reader.readLine())!=null){
                    builder.append(s);
                }
                String string=builder.toString().trim();
            }
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
方法三：HttpClient GET请求
new Thread() {
 
            public void run() {
                // android4.0之后,耗时操作放在子线程里
                try {
                    HttpClient httpClient = new DefaultHttpClient();
                    String path = "http://apis.juhe.cn/train/s2swithprice?start="
                            + start
                            + "&end="
                            + end
                            + "&key=6a12c4348d9174020aa24cac0d410355";
                    HttpGet httpGet = new HttpGet(path);
                    HttpResponse httpResponse = httpClient.execute(httpGet);
                    int code = httpResponse.getStatusLine().getStatusCode();
                    if (code == 200) {
                        InputStream inputStream = httpResponse.getEntity()
                                .getContent();
                        Gson gson = new Gson();
                        Bean bean = gson.fromJson(new InputStreamReader(
                                inputStream), Bean.class);
                        list = bean.result.list;
                        handler.sendEmptyMessage(0);
                    }
                } catch (ClientProtocolException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            };
 
        }.start();
方法四：HttpClient POST请求
    new Thread() {
            private Data data;
 
            public void run() {
                // android4.0之后,耗时操作放在子线程里
                try {
                    HttpClient httpClient = new DefaultHttpClient();
                    HttpPost httpPost = new HttpPost(   "http://japi.juhe.cn/qqevaluate/qq");
                    // 集合
                    List<BasicNameValuePair> list = new ArrayList<BasicNameValuePair>();
                    // 添加参数
                    list.add(new BasicNameValuePair("key","b4f60e610563b871fd43b615b54f727a"));
                    list.add(new BasicNameValuePair("qq", qq));
                    // 发送实体对象
                    HttpEntity entity = new UrlEncodedFormEntity(list, "utf-8");
                    httpPost.setEntity(entity);
                    try {
                        // 发送请求
                        HttpResponse httpResponse = httpClient.execute(httpPost);
                        // 获取响应码
                        int code = httpResponse.getStatusLine().getStatusCode();
                        if (code == 200) {
                            // 获取实体信息
                            HttpEntity entity2 = httpResponse.getEntity();
                            String string = EntityUtils.toString(entity2,"utf-8");
                            Gson gson = new Gson();
                            Bean bean = gson.fromJson(string, Bean.class);
                            data = bean.result.data;
                            runOnUiThread(new Runnable() {
                                public void run() {
                                    t.setText("QQ测试结果:" + data.conclusion);
                                    t2.setText("QQ测试分析:" + data.analysis);
                                }
                            });
                        } else {
                            Toast.makeText(MainActivity.this, "无qq参数或者格式不正确", 0)
                                    .show();
                        }
                    } catch (ClientProtocolException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                } catch (UnsupportedEncodingException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            };
 
        }.start();
方法五：httpUtils    GET请求
String string="http://v.juhe.cn/weixin/query?key=484057f2721591bc4730f6b370c7ff31&pno=1";
        HttpUtils httpUtils=new HttpUtils();
        httpUtils.send(HttpMethod.GET, string, new RequestCallBack<String>() {
            //联网失败
            @Override
            public void onFailure(HttpException arg0, String arg1) {
                // TODO Auto-generated method stub
            }
            //联网成功
            @Override
            public void onSuccess(ResponseInfo<String> arg0) {
                // TODO Auto-generated method stub
                String result = arg0.result;
                Log.i("TAG", result);
            }
        });
//方法四：httpUtils    POST请求
HttpUtils httpUtils=new HttpUtils();
        RequestParams params=new RequestParams();
        params.addBodyParameter("key", "484057f2721591bc4730f6b370c7ff31");
        params.addBodyParameter("pno", "1");
        httpUtils.send(HttpMethod.POST, "http://v.juhe.cn/weixin/query", params, new RequestCallBack<String>() {
            //联网失败
            @Override
            public void onFailure(HttpException arg0, String arg1) {
                // TODO Auto-generated method stub
            }
            //联网成功
            @Override
            public void onSuccess(ResponseInfo<String> arg0) {
                // TODO Auto-generated method stub
                String result = arg0.result;
                Log.i("TAG", result);
            }
        });
