使用 Coroutine + Retrofit 将文件/图像上传到服务器

Question

我是新协程，我尝试将文件上传到服务器（使用 Retrofit 2.9.0），但没有得到响应。下面是我的代码：

private suspend fun uploadFile(inputFiles: List<String>,channel:Channel<Any>): List<FileResponse>? {
        val partList = buildFilePart(inputFiles)
        QLog.d(TAG,"uploadFile going 1")
        val response = RequestHelper.getUpLoadFilesKotlinRequest().uploadFiles(partList)
        QLog.d(TAG,"uploadFile going 2")
        return response.body()
}
interface UploadFileApiKotlin {
    @Multipart
    @POST("/uploadFile")
    suspend fun uploadFiles(
        @Part listUri: List<MultipartBody.Part>
    ): Response<List<FileResponse>?>
}

查看logcat后，只看到一行代码：

上传文件进行 1

没有日志行：uploadFile go 2

协程似乎暂停在该行：

val response = RequestHelper.getUpLoadFilesKotlinRequest().uploadFiles(partList)

如何解决这个问题？

我发布了另一个问题最后我自己得到了答案

suspend fun uploadFile() = suspendCoroutine<Response<List<FileResponse>?>> { continuation ->
    val call = RequestHelper.getUpLoadFilesKotlinRequest().uploadFiles(partList)
    call.enqueue(object : Callback<Response<List<FileResponse>?>> {
        override fun onResponse(
            call: Call<Response<List<FileResponse>?>>,
            response: Response<Response<List<FileResponse>?>>
        ) {
            // Resume coroutine with a value provided by the callback
            continuation.resumeWith(response.data)
        }

        override fun onFailure(
            call: Call<Response<List<FileResponse>?>>,
            t: Throwable
        ) {
            continuation.resumeWithException(t)
        }
    })
}
