android开发http请求POST&GET封装工具

最近一直想着封装个网络请求框架,但是看到有很多博客有封装而且还不错,于是就想着封装一个安卓带的,以便自己以后使用. 一,请求成功和失败回调接口 public interface OnResponseListner { void onSucess(String response); void onError(String error); } 二,post&get请求方法工具类 public class HttpUtlis { /** *get请求封装 */ public static void getRequest(String url, Map<String,String> params, String encode,OnResponseListner listner) { StringBuffer sb = new StringBuffer(url); sb.append("?"); if (params!=null && !params.isEmpty()){ for (Map.Entry<String,String> entry:params.entrySet()) { //增强for遍历循环添加拼接请求内容 sb.append(entry.getKey()).append("=").append(entry.getValue()).append("&"); } sb.deleteCharAt(sb.length()-1); if (listner!=null) { try { URL path = new URL(sb.toString()); if (path!=null) { HttpURLConnection con = (HttpURLConnection) path.openConnection(); con.setRequestMethod("GET"); //设置请求方式 con.setConnectTimeout(3000); //链接超时3秒 con.setDoOutput(true); con.setDoInput(true); OutputStream os = con.getOutputStream(); os.write(sb.toString().getBytes(encode)); os.close(); if (con.getResponseCode() == 200) { //应答码200表示请求成功 onSucessResopond(encode, listner, con); } } } catch (Exception error) { error.printStackTrace(); onError(listner, error); } } } } /** * POST请求 */ public static void postRequest(String url,Map<String,String> params,String encode,OnResponseListner listner){ StringBuffer sb = new StringBuffer(); if (params!=null && !params.isEmpty()){ for (Map.Entry<String,String> entry: params.entrySet()) { sb.append(entry.getKey()).append("=").append(entry.getValue()).append("&"); } sb.deleteCharAt(sb.length()-1); } if (listner!=null) { try { URL path = new URL(url); if (path!=null){ HttpURLConnection con = (HttpURLConnection) path.openConnection(); con.setRequestMethod("POST"); //设置请求方法POST con.setConnectTimeout(3000); con.setDoOutput(true); con.setDoInput(true); byte[] bytes = sb.toString().getBytes(); OutputStream outputStream = con.getOutputStream(); outputStream.write(bytes); outputStream.close(); if (con.getResponseCode()==200){ onSucessResopond(encode, listner, con); } } } catch (Exception e) { e.printStackTrace(); onError(listner, e); } } } private static void onError(OnResponseListner listner,Exception onError) { listner.onError(onError.toString()); } private static void onSucessResopond(String encode, OnResponseListner listner, HttpURLConnection con) throws IOException { InputStream inputStream = con.getInputStream(); ByteArrayOutputStream baos = new ByteArrayOutputStream();//创建内存输出流 int len = 0; byte[] bytes = new byte[1024]; if (inputStream != null) { while ((len = inputStream.read(bytes)) != -1) { baos.write(bytes, 0, len); } String str = new String(baos.toByteArray(), encode); listner.onSucess(str); } } }

三,activity中使用直接类名静态方法调用

String url=""; String encode="utf-8"; public void GET(View view){ Map<String,String> map=new HashMap<>(); map.put("userName",""); map.put("pwd",""); HttpUtlis.getRequest(url, map,encode, new OnResponseListner() { @Override public void onSucess(String response) { } @Override public void onError(String error) { } }); }
