Question

protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
    request.setCharacterEncoding("UTF-8");  
        String name = request.getParameter("name");  
        String age  = request.getParameter("age");  
        System.out.println("POST");  
        System.out.println("name="+name);  
        System.out.println("age="+age);  
        response.setCharacterEncoding("UTF-8"); 
        if(name.equals("q")&&age.equals("1")){
            OutputStream out = response.getOutputStream();  
            BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(out));
            writer.write("success");  
            writer.flush(); 
            writer.close(); 
        }else{
            OutputStream out = response.getOutputStream();  
            BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(out));
            writer.write("false");  
            writer.flush(); 
            writer.close(); 
        }
}

Answer 1

我android端接受数据
InputStream in = response.getEntity().getContent();
BufferedReader str = new BufferedReader(
new InputStreamReader(in));
String line = null;
line=str.readLine();
比如"success" 接受来之后，在success左右两边多了俩空格" success "

Answer 2

接收之后使用trim()去除空格呢？
