Question

我的GET请求在Android Studio中无法正常运行。我试图在邮递员中提出相同的请求，结果我总是得到带有正确正文的响应代码200。但是，使用Retrofit时，当响应主体为空（没有数据）时，我会收到onResponse（200代码），而当响应主体不为空（有一些保留）时，我会得到onFailure。

编辑：我刚刚在日志中注意到这样的错误：Expected BEGIN_OBJECT but was STRING at line 1 column 22 path $[0].reservationDate

EDIT2：JSON响应

[
    {
        "reservationDate": "2019-10-30",
        "id": "4"
    }
]

API服务：

    @Headers("Authorization: Bearer ...")
    @GET("reservations")
    fun getSchedule(@Query("id") id: Int,
                    @Query("reservationDate") reservationDate: LocalDate

    ):  Call<List<ScheduleModel>>


    companion object {
        fun create(): ScheduleService{

            var retrofit = Retrofit.Builder()
                .baseUrl("myUrl")
                .addConverterFactory(GsonConverterFactory.create())
                .build()

            return retrofit.create(ScheduleService::class.java)
        }
    }
}

data class ScheduleModel(
    val id: Int,
    val reservationDate: LocalDate
)

fun getReservations() {
        var service = ScheduleService.create()
        var localdate = LocalDate.of(2019,10,30)

        var call = service.getSchedule(4, localdate)

        call.enqueue(object : Callback<List<ScheduleModel>> {

            override fun onResponse(call: Call<List<ScheduleModel>>, response: Response<List<ScheduleModel>>) {
                if (response.code() == 200) {
                    Toast.makeText(applicationContext, "It's ok", Toast.LENGTH_SHORT).show()
                }
            }

            override fun onFailure(call: Call<List<ScheduleModel>>, t: Throwable) {
                Toast.makeText(applicationContext, "Failure", Toast.LENGTH_SHORT).show()
            }
        })
    }

您的id和reservationDate的响应是一个String，但是您尝试将其解析为Int和LocalDate。更改类型，它将起作用。

改造-非空主体上为onFailure，空主体上为onResponse
