Android之用HttpURLConnection参数以XML形式封装的部分关键代码

HttpURLConnection参数以XML形式封装

 //得到连接
    public static HttpURLConnection setRequest(String urlStr) {
        HttpURLConnection con = null;
        try {
            URL url = new URL(urlStr);
            try {
                con = (HttpURLConnection) url.openConnection();
                con.setDoOutput(true);
                con.setDoInput(true);
                con.setRequestProperty("Pragma:", "no-cache");
                con.setRequestMethod("POST");
                con.setRequestProperty("Cache-Control", "no-cache");
                con.setRequestProperty("Content-Type", "text/xml");
            } catch (IOException e) {
                e.printStackTrace();
            }
        } catch (MalformedURLException e) {
            e.printStackTrace();
        }
        return con;
    }

请求参数xml的封装，以注册为例子

//注册参数
    public static String getXmlRegister(String username, String userpwd, String mobile, String email, String sex, String birthday, String address) {
        StringBuilder sb = new StringBuilder();
        sb.append("<xml>");
        sb.append("<username>" + username + "</username>");
        sb.append("<userpwd>" + userpwd + "</userpwd>");
        sb.append("<mobile>" + mobile + "</mobile>");
        sb.append("<email>" + username + "</email>");
        if (sex != null) {
            sb.append("<sex>" + sex + "</sex>");//是否必填 否
        }
        if (birthday != null) {
            sb.append("<birthday>" + birthday + "</birthday>");//是否必填 否
        }
        if (address != null) {
            sb.append("<address>" + address + "</address>");//是否必填 否
        }
        sb.append("</xml>");
        return sb.toString();
    }

注册请求代码

 //注册请求
    public static String postByRegister(String urlStr, String username, String pwd, String mobile, String email, String sex, String birthday, String address) {
        OutputStreamWriter out = null;
        String line = "";
        BufferedReader in = null;
        try {
            HttpURLConnection con = setRequest(urlStr);
            out = new OutputStreamWriter(con.getOutputStream());
            String xmlInfo = getXmlRegister(username, pwd, mobile, email, sex, birthday, address);
            System.out.println("urlStr=" + urlStr);
            System.out.println("xmlInfo=" + xmlInfo);
            out.write(new String(xmlInfo.getBytes("ISO-8859-1")));
            out.flush();
            out.close();
            // 使用输出流来输出字符(可选)
            if (con.getResponseCode() != 200) throw new RuntimeException("请求url失败");
            InputStream is = con.getInputStream();// 获取返回数据
            ByteArrayOutputStream baout = new ByteArrayOutputStream();
            byte[] buf = new byte[1024];
            int len;
            while ((len = is.read(buf)) != -1) {
                baout.write(buf, 0, len);
            }
            line = new String(baout.toByteArray());
            System.out.println(line);
            out.close();
            return line;
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return line;
    }
