把字符串转化成对象.

{"access_token":"zTZFxLrhM1vHAjXmq1ymk1JT8nlOKja4urFIr9PWqLYvFH9ZbWo8R6BmQqUr7VbArzBoZWOfBNI_fYGlO37r5t9s5jeYlxXXg4UXISCz2G9fOWvwzrOM86e8rv9f1eSOGYVhAHAPHE","expires_in":7200}

这段是网络上给你返回回来的东西.gson.fromJson()之后是转化成一个对象

return "AccessToken [access_token=" + access_token + ", expires_in="+ expires_in + "]";

AccessToken [access_token=PQ_cs-BXBgspo0JNSlW_ytV3virET-nsK5muSsfVQ02qcp1dHDDK86dDWZ3WwDxMgT0_zqhCGaHq-Y1F6rjLXJnxN9d3EAThzkmtaMduYmXxAL98pt2a03HNAFXBESjjVVWdABARRS, expires_in=7200]

获得token之后首先是构建出来菜单的报文(JSON串).首先是要分析JSON串的组成方式.

定义菜单的Bean对象.Bean对象不是微信核心的东西.

菜单这一块是很复杂的,AccessToken.java是定义了的一个Bean,为什么要有token？因为菜单的参数需要token。菜单接口的参数需要token。

CaiDan也是一个Bean.WX_Info是保存微信的信息,获取token需要用的.WX_Token是得到token的信息。

这一块结合的东西多了,它要和token结合在一起使用。

创建菜单这一块和之前获得token都是网络操作,但是它们还是有区别的。

创建菜单需要传递token参数.

Sets the value of the doInput field for this URLConnection to the specified value.
A URL connection can be used for input and/or output. Set the DoInput flag to true if you intend to use the URL connection for input, false if not. The default is true.
