第一章：概述

1-1 课程简介

本课程是在之前的《初识Java微信公众号开发》课程基础之上的。
之前入门课程主要讲解了

微信公众号及公众号平台的相关概念
编辑模式和开发模式的相关操作

课程内容

消息回复接口
素材管理接口
自定义菜单接口
百度翻译API

1-2 微信公众平台测试号

因个人订阅号权限有限，很多高级接口无法使用，所以可以申请测试账号，测试账号对这些接口的权限都放开了。

第二章：素材管理接口

2-1 图文消息

复制项目wxdevaccess重命名为wxdevadvanced。其中POM文件如下

public class TransResult {private String from;private String to;private Data data;private String errno;public String getFrom() {return from;}public void setFrom(String from) {this.from = from;}public String getTo() {return to;}public void setTo(String to) {this.to = to;}public Data getData() {return data;}public void setData(Data data) {this.data = data;}public String getErrno() {return errno;}public void setErrno(String errno) {this.errno = errno;}
}
