Upload file/image into server using Coroutine + Retrofit(使用Coroutine+Retrofit将文件/图像上传到服务器)
问题描述
我是新的协程程序,我尝试将文件上传到服务器(使用Retroff2.9.0),但没有收到响应。 下面是代码行
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>?>
}
检查logcat后,我只看到一行代码:
正在上传文件%1
没有日志行:UploadFile Going%2
协同例程似乎在以下行挂起:val response = RequestHelper.getUpLoadFilesKotlinRequest().uploadFiles(partList)
您能帮我解决这个问题吗? 提前感谢
推荐答案
我发布了another question,最终我自己得到了答案
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)
}
})
}
