Answer 1

应该是不能用get的，开源项目httpclient比较好用post地址:http://5pi.cn/member/checklogin.php
参数:
username:mememomo
password:******
chkcode:5354
login:1

Answer 2

给你一个模拟登录qq空间的例子:登录方法:        public static String login(final String qq,final String password){
                HashMap<String, String> params=new HashMap<String, String>();
                params.put("login_url", "http://pt.3g.qq.com/s?aid=nLogin");
                params.put("sidtype", "1");
                params.put("loginTitle", "手机腾讯网");
                params.put("bid", "0");
                params.put("qq", qq);
                params.put("pwd", password);
                params.put("loginType", "1");
                try {
                        String response=WebUtils.doPost(QQ_LOGIN_URL, params, 0, 0);
                        int sidIndex=response.indexOf("sid");
                        SID=response.substring(sidIndex+4, sidIndex+28);
                } catch (IOException e) {
                        e.printStackTrace();
                }
                return SID;
        }WebUtils类的doPost方法:
        
public static String doPost(String url, Map<String, String> params,int connectTimeout,int readTimeout) throws IOException {
                String query=buildQuery(params, DEFAULT_CHARSET);
                byte[] content=null;
                if(query!=null){
                        content=query.getBytes(DEFAULT_CHARSET);
                }
                return doPost(url, CTYPE, content, connectTimeout, readTimeout);
        }        public static String doPost(String url, String ctype, byte[] content,int connectTimeout,int readTimeout) throws IOException {
                HttpURLConnection conn = null;
                OutputStream out = null;
                String rsp = null;
                try {
                        try{
                                conn = getConnection(new URL(url), METHOD_POST, ctype); 
                                conn.setConnectTimeout(connectTimeout);
                                conn.setReadTimeout(readTimeout);
                                out = conn.getOutputStream();
                                out.write(content);
                                rsp = getResponseAsString(conn);
                        }catch(IOException e){
                                throw e;
                        }
                }finally {
                        if (out != null) {
                                out.close();
                        }
                        if (conn != null) {
                                conn.disconnect();
                        }
                }
                return rsp;
        }        private static HttpURLConnection getConnection(URL url, String action, String ctype)
                        throws IOException {
                HttpURLConnection conn = (HttpURLConnection) url.openConnection();
                conn.setRequestMethod(action);
                conn.setDoInput(true);
                conn.setDoOutput(true);
                conn.setRequestProperty("Accept", "text/xml,text/javascript,text/html");
                conn.setRequestProperty("User-Agent", USER_AGENT);
                conn.setRequestProperty("Content-Type", ctype);
                return conn;
        }        private static String getStreamAsString(InputStream stream, String charset) throws IOException {
                try {
                        BufferedReader reader = new BufferedReader(new InputStreamReader(stream, charset));
                        StringWriter writer = new StringWriter();
                        char[] chars = new char[256];
                        int count = 0;
                        while ((count = reader.read(chars)) > 0) {
                                writer.write(chars, 0, count);
                        }
                        return writer.toString();
                } finally {
                        if (stream != null) {
                                stream.close();
                        }
                }
        }

Answer 3

返回信息是验证码出错,说明楼主get方式提交时成功的，只是验证码输入错了
看了下paramStr的拼凑
 String paramStr = "?"+ "&userName=" + userName + "&password=" + password + "&chkcode=" + chkcode+"&login=1"; //验证码和login参数直接少了个&导致你验证码变成了你输入的1386login=1了所以返回了验证码出错。楼主把这个&符号加上再试试吧

Answer 4

补充下
String paramStr = "?"+ "&userName=" + userName + "&password=" + password + "&chkcode=" + chkcode+"&login=1"; 
第一个参数后面不用跟&正确的格式应该是
String paramStr = "?"+ "userName=" + userName + "&password=" + password + "&chkcode=" + chkcode+"&login=1"; //参数名userName前面的&去掉

Answer 5

应该不是post 的问题，数据没有获取到应该是参数问题。
