Kotlin中Retrofit 2中的多个空白问题标题

val client = OkHttpClient.Builder()
    .connectTimeout(10, TimeUnit.SECONDS)
    .readTimeout(10, TimeUnit.SECONDS)
    .build()

val retrofit = Retrofit.Builder()
    .baseUrl(BASE_URL)
    .client(client)
    .build()

interface MyApi {
    @GET("endpoint")
    fun getData(): Call<Data>
}

val api = retrofit.create(MyApi::class.java)
api.getData().enqueue(object : Callback<Data> {
    override fun onResponse(call: Call<Data>, response: Response<Data>) {
        if (response.isSuccessful) {
            val data = response.body()
            // 处理响应数据
        } else {
            // 处理服务器返回错误码
        }
    }

    override fun onFailure(call: Call<Data>, t: Throwable) {
        // 处理请求失败的情况
    }
})

interface MyApi {
    @GET("endpoint")
    fun getData(@Query("id") id: String): Call<Data>
}

val api = retrofit.create(MyApi::class.java)
api.getData("123").enqueue(object : Callback<Data> {
    // 处理响应数据和错误
})

data class User(val name: String, val age: Int)

interface MyApi {
    @POST("endpoint")
    fun createUser(@Body user: User): Call<Response>
}

val api = retrofit.create(MyApi::class.java)
val user = User("John", 25)
api.createUser(user).enqueue(object : Callback<Response> {
    // 处理响应数据和错误
})
