网上找了很多资料都试了个遍，最后这个是可以用的，

大家可以看一下，

android代码：

private void sendRequest(final String sign){
        new Thread(new Runnable() {
            @Override
            public void run() {
                String url="http://"+ MyIp.ip+":8080/CarSafe/InsertBlogServlet";
                HttpURLConnection connection=null;
                try{
                    URL posturl=new URL(url);
                    connection=(HttpURLConnection)posturl.openConnection();
                    connection.setDoOutput(true);
                    connection.setDoInput(true);
                    connection.setRequestMethod("POST");
                    connection.setUseCaches(false);
                    connection.setInstanceFollowRedirects(true);
                    connection.connect();
                    DataOutputStream out=new DataOutputStream(connection.getOutputStream());
                    String content="car_id="+ Person.car_id;
                    String content1="&username="+URLEncoder.encode(Person.usename,"UTF-8");
                    String content2="&mysign="+URLEncoder.encode(sign,"UTF-8");
                    Log.d("content", Person.usename);
                    out.writeBytes(content);
                    out.writeBytes(content1);
                    out.writeBytes(content2);
                    out.flush();
                    out.close();
                    BufferedReader reader=new BufferedReader(new InputStreamReader(connection.getInputStream()));
                    String line;
                    StringBuffer response=new StringBuffer();
                    while((line=reader.readLine())!=null){
                        response.append(line);
                    }
                    reader.close();
                    Message message=new Message();
                    message.what=SEND_SIGN;

服务器：

car\_id=Integer.parseInt(request.getParameter("car\_id"));  
        username=new String(request.getParameter("username").getBytes("ISO-8859-1"),"UTF-8");  
        mysign=new String(request.getParameter("mysign").getBytes("ISO-8859-1"),"UTF-8");
