GAE standard project cannot upload files to GCS bucket

[전하정]

Hi. I'm trying to make a website that allows users to upload files from their local file system to the website. I'm now implementing API for uploading files to the GCS bucket.

I used the code from Google docs, which was very helpful. This code worked pretty well when I run my project on a local server(localhost:8080), however, when I deployed my project to GAE and run again({my-project-id}.appspot.com), it returns java.nio.file.NoSuchFileException.

I think the problem is that GAE server cannot read any file path from local computer, such as C:/users/desktop/test.txt, but I think I need path like this because I have to make users upload their files from their own computer.

Here is the code that I used:

    Storage storage = StorageOptions.newBuilder().setProjectId(projectId).build().getService();

    BlobId blobId = BlobId.of(uploadReqDto.getBucketName(), uploadReqDto.getUploadFileName());

    BlobInfo blobInfo = BlobInfo.newBuilder(blobId).build();

    storage.create(blobInfo, Files.readAllBytes(Paths.get(uploadReqDto.getLocalFileLocation())));

uploadReqDto.getBucketName(),  uploadReqDto.getUploadFileName() and uploadReqDto.getLocalFileLocation() are request parameters for the POST API, which looks like:

{

  "bucketName": "myBucketName",

  "uploadFileName": "Test1.txt",

  "localFileLocation": "C:/users/desktop/my/file/path"

}

Is there any special way to configure paths from local computer when the project is deployed and running on GAE?
