　　myBean.java

因为用到了Gson来解析，所以根据返回的json字符串的key来写一个bean。

package com.wyl.jqr;public class myBean {String code;String text;public String getCode() {return code;}public void setCode(String code) {this.code = code;}public String getText() {return text;}public void setText(String text) {this.text = text;}}
