android客户端提交数据到服务器中文乱码三种解决方案.doc

在开始学android的时候提交数据到服务器出现中文乱码问题,经过多方面查资料终于将漂亮的中文在服务器端获取到了.下面总结出三种方法可已经中文乱码解决.第一种.在客户端适用HttpPost方式提交数据:public static String toCallOnServer(String path,String encode) throws ClientProtocolException, IOExceptionHttpPost httpPost = new HttpPost(pathString +path);DefaultHttpClient client = new DefaultHttpClient();/httpPost.addHeader(charset, HTTP.UTF_8);HttpResponse response = client.execute(httpPost);httpPost.addHeader(Content-Type, text/html); /这行很重要 httpPost.addHeader(charset, HTTP.UTF_8); /这行很重要/上述两行制定提交数据的时候通过什么方式来处理URL,第一句,著名这个URL是以text/html的格式发送给服务器的(个人理解),第二句,设定url的编码方式.以服务器端一致.在.在这里讲解下URL在传递的过程,首先tomcat在接受URL的时候是以iso-8859-1的编码方式进行编码的,在服务器端接收到数据后要用 new String(name.getBytes(“iso-8859-1),”utf-8”) 这种方式进行转码. if(response.getStatusLine().getStatusCode()=200)InputStream inputStream = response.getEntity().getContent();return getContext(inputStream, encode);return ;测试代码:public void testAddQuestion()try String pathS =06:8080/jiudian/AndroidServlet?action=edit&uname=jack&question=你最喜欢的电影&answer=哈利波特;/String newPath = URLEncoder.encode(pathS, utf-8);String result = HttpUtils.toCallOnServer(pathS, utf-8);Log.i(TAG, result); catch (ClientProtocolException e) / TODO Auto-generated catch blocke.printStackTrace(); catch (IOException e) / TODO Auto-generated catch blocke.printStackTrace();服务器端代码:String msg = ;String uname = request.getParameter(uname).trim();String question = new String(request.getParameter(question).getBytes(iso-8859-1),utf-8);String answer = new String(request.getParameter(answer).getBytes(iso-8859-1),utf-8);第二种方式:适用URL 和HTTPUrlConnetion 连接适用GET方法上传数据URL url = new URL(path);HttpURLConnection connection = (HttpURLConnection) url.openConnection();connection.setDoInput(true);connection.setDoOutput(true);connection.setRequestMethod(GET);服务器代码:String msg = ;String uname = request.getParameter(uname).trim();String question = new String(request.getParameter(question).getBytes(iso-8859-1),utf-8);String answer = new String(request.getParameter(answer).getBytes(iso-8859-1),utf-8);测试代码:测试代码中有需要注意的地方String path = 06:8080/jiudian/AndroidServlet?action=edit&uname=jack;StringBuffer buffer = new StringBuffer(path);/&question=asdfdsa&answer=asdfdasbuffer.append(&question=).append(URLEncoder.encode(你最喜欢的电影, utf-8).append(&answer=).append(URLEncoder.encode(哈利波特, utf-8);/String result =HttpUtils.loginPostData(path, map);String result = HttpUtils.checkLogin(buffer.toString();Log.i(TAG, result);在测试代码中要把中文乱码进行转换处理第三种方式:讲数据封装成map格式,适用URL 和HttpURLConnection连接,用POST方式传递.public static String loginPostData(String path, Map map) InputStream inputStream = null;OutputStream outputStream = null;try URL url = new URL(path);HttpURLConnection connection = (HttpURLConnection) url.openConnection();connection.setDoInput(true);connection.setDoOutput(true);connection.setRequestMethod(POST);StringBuffer buffer = new StringBuffer();if (map != null & !map.isEmpty() for (Map.Entry entry : map.entrySet() buffer.append(entry.getKey().append(=).append(URLEncoder.encode(entry.getValue(), utf-8).append(&);buffer.deleteCharAt(buffer.length() - 1);byte data = buffer.toString().getBytes();connection.setRequestProperty(Content-Type,application/x-www-form-urlencoded);connection.setRequestProperty(Content-Length,String.valueOf(data.length);outputStream = connection.getOutputStream();outputStream.write(data);if (connection.getResponseCode() = 200) inputStream = connection.getInputStream();return getContext(inputStream, utf-8); catch (MalformedURLException e) / TODO Auto-generated catch blocke.printStackTrace(); catch (IOException e) / TODO Auto-generated catch blocke.printStackTrace(); finally try inputStream.close();outputStream.close(); catch (IOException e) / TODO Auto-generated catch blocke.printStackTrace();return null;服务器代码:String uname = request.getParameter(uname).trim();String question = request.getParameter(question);String answer = request.getParameter(answer);测试代码:String path = http:/19
