使用 public void fileupload(View v){ try{ EditText et_filepath = (EditText) findViewById(R.id.et_filepath); //获取输入的文件地址 String filepath = et_filepath.getText().toString().trim();

//使用开源Utils做上传操作 AsyncHttpClient asyncHttpClient = new AsyncHttpClient(); RequestParams params = new RequestParams(); params.put("filename", new File(filepath)); //url : 请求服务器的url asyncHttpClient.post("http://192.168.13.83:8080/UploaderServlet", params, new AsyncHttPResponseHandler() { @Override public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) { if(statusCode == 200){ Toast.makeText(MainActivity.this, "上传成功", 0).show(); } } @Override public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) { } }); }catch (Exception e) { e.printStackTrace(); }}

实现数据的传输

get方式： public static void requestNetForGetLogin(final Context context,final Handler handler ,final String username, final String passWord) { //使用HttpClient请求服务器将用户密码发送服务器验证 try{ String path = "http://192.168.13.83:8080/itheima74/servlet/LoginServlet?username="+URLEncoder.encode(username,"utf-8")+"&pwd="+URLEncoder.encode(password,"utf-8"); //创建一个AsyncHttpClient对象 AsyncHttpClient asyncHttpClient = new AsyncHttpClient(); asyncHttpClient.get(path, new AsyncHttpResponseHandler() { @Override public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) { //statusCode:状态码 headers：头信息 responseBody：返回的内容，返回的实体 //判断状态码 if(statusCode == 200){ //获取结果 try { String result = new String(responseBody,"utf-8"); Toast.makeText(context, result, 0).show(); } catch (UnsupportedEncodingException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } @Override public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) { System.out.println("...............onFailure"); } }); }catch (Exception e) { e.printStackTrace(); }} post方式： String path = "http://192.168.13.83:8080/itheima74/servlet/LoginServlet"; AsyncHttpClient asyncHttpClient = new AsyncHttpClient(); RequestParams params = new RequestParams(); params.put("username", username); params.put("pwd", password); //url: parmas：请求时携带的参数信息 responseHandler：是一个匿名内部类接受成功过失败 asyncHttpClient.post(path, params, new AsyncHttpResponseHandler() { @Override public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) { //statusCode:状态码 headers：头信息 responseBody：返回的内容，返回的实体 //判断状态码 if(statusCode == 200){ //获取结果 try { String result = new String(responseBody,"utf-8"); Toast.makeText(context, result, 0).show(); } catch (UnsupportedEncodingException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } @Override public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) { } });
