如何将新文件上传到GCP存储桶？

Question

我发现excellent example如何读取/更新GCP存储桶中的现有文件：

@RestController
public class WebController {

    @Value("gs://${gcs-resource-test-bucket}/my-file.txt")
    private Resource gcsFile;

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String readGcsFile() throws IOException {
        return StreamUtils.copyToString(
                this.gcsFile.getInputStream(),
                Charset.defaultCharset()) + "\n";
    }

    @RequestMapping(value = "/", method = RequestMethod.POST)
    String writeGcs(@RequestBody String data) throws IOException {
        try (OutputStream os = ((WritableResource) this.gcsFile).getOutputStream()) {
            os.write(data.getBytes());
        }
        return "file was updated\n";
    }
}

但是我找不到使用spring gloud GCP将新文件上传到GCP存储桶的方法。

如何实现？

Answer 1

@Autowired
private Storage gcs;

public void upload(String report) {

    gcs.create(BlobInfo
                    .newBuilder("bucket_name", "fileName.json")
                    .build(),
            report.getBytes());

}
