接口模型

data class InfoBean(
val errcode: Int = 0, // 41002
val errmsg: String = "" // appid missing rid: 5fcf41fa-678038ea-7e15562d
)

获取数据

val retrofit = Retrofit.Builder()
 .baseUrl("https://api.weixin.qq.com/")
 .addConverterFactory(GsonConverterFactory.create())
 .addConverterFactory(ScalarsConverterFactory.create())  //使用string
 .build()
// 创建 网络请求接口 的实例
val request: TextService = retrofit.create(TextService::class.java)
//对 发送请求 进行封装
val call: Call<InfoBean> = request.get()
call.enqueue(object :Callback<InfoBean>{
override fun onResponse(call: Call<InfoBean>, response: Response<InfoBean>) {
val demo: InfoBean? = response.body()
 Log.d("okkkk",demo!!.errmsg)
 }
override fun onFailure(call: Call<InfoBean>, t: Throwable) {
 Log.d("错了","dddddd")
 }
})
