Retrofit POST请求根路径的正确姿势

import okhttp3.RequestBody
import retrofit2.Call
import retrofit2.http.Multipart
import retrofit2.http.POST
import retrofit2.http.Part

// 假设 Result 是你的响应数据模型
data class Result(val status: String, val message: String)

interface GetRequestInterface {
    @Multipart
    @POST("/") // 正确指定根路径
    fun updateProfile(
        @Part("tile_mode") fullName: Int,
        @Part("raw_image") image: RequestBody
    ): Call<Result>
}

import retrofit2.Retrofit
import retrofit2.converter.gson.GsonConverterFactory
import retrofit2.adapter.rxjava.RxJavaCallAdapterFactory // 如果你使用RxJava

fun main() {
    val retrofit = Retrofit.Builder()
        .baseUrl("https://blog.banned.top:2054") // 设置基础URL
        .addConverterFactory(GsonConverterFactory.create())
        // .addCallAdapterFactory(RxJavaCallAdapterFactory.create()) // 根据你的项目需求选择是否添加
        .build()

    val request = retrofit.create(GetRequestInterface::class.java)

    // 假设 someParameter 是你的实际参数
    val someParameterFullName = 123
    val someParameterImage: RequestBody = RequestBody.create(null, "dummy_image_data".toByteArray()) // 示例RequestBody

    val call: Call<Result> = request.updateProfile(someParameterFullName, someParameterImage)

    // 执行请求 (在实际应用中，通常在后台线程执行)
    // call.enqueue(object : Callback<Result> {
    //     override fun onResponse(call: Call<Result>, response: Response<Result>) {
    //         if (response.isSuccessful) {
    //             println("Success: ${response.body()}")
    //         } else {
    //             println("Error: ${response.code()} - ${response.errorBody()?.string()}")
    //         }
    //     }
    //
    //     override fun onFailure(call: Call<Result>, t: Throwable) {
    //         println("Failure: ${t.message}")
    //     }
    // })
    println("Retrofit call created successfully for root path.")
}
