Retrofit：中要用到的包

compile 'io.reactivex:rxjava:x.y.z'
compile 'io.reactivex:rxandroid:1.0.1'
compile 'com.squareup.retrofit2:retrofit:2.0.2'
compile 'com.squareup.retrofit2:converter-gson:2.0.2'
compile 'com.squareup.retrofit2:adapter-rxjava:2.0.2'

由于用到了Post请求，使用了JsonObject传递数据，所以导入：

compile 'com.alibaba:fastjson:1.1.56.android'

代码很low，仅供参考。
