软工每日总结29

今天的主要工作就是将数据处理的客户端部分完成，从同学写好的安卓交互程序中读取用户名和密码等信息，并将其提交给我的服务器后台程序处理，并读取反馈信息反馈给用户交互模块，主要涉及到http连接以及json数据的处理等内容。

主要代码

private Handler handler=new Handler(){
    public void handleMessage(Message msg){
        switch (msg.arg1) {
            case 1:
                my_json mj;
                mj=take_json(resultData);
                Toast toast=Toast.makeText(getApplicationContext(), mj.id+" "+mj.state+" "+mj.code, Toast.LENGTH_SHORT);
                toast.show();
                //mTextView.setText(mj.id+" "+mj.state+" "+mj.code);
                break;
            default:
                break;
        }
    }
};
class my_json
{
    public int id;
    public String state;
    public String code;
}
private my_json take_json(String JSON)
{
    my_json mj=new my_json();
    try {
        JSONTokener jsonParser = new JSONTokener(JSON);
        // 此时还未读取任何json文本，直接读取就是一个JSONObject对象。
        // 如果此时的读取位置在"name" : 了，那么nextValue就是"yuanzhifei89"（String）
        JSONObject person = (JSONObject) jsonParser.nextValue();
        // 接下来的就是JSON对象的操作了

        mj.id=person.getInt("id");
        mj.state=person.getString("state");
        mj.code=person.getString("code");
    } catch (JSONException ex) {
        // 异常处理代码
    }
    return mj;
}
