我找到了如何读取/更新 GCP 存储桶中现有文件的绝佳示例:
@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";
}
}
但我找不到如何使用 spring gloud GCP 将新文件上传到 GCP 存储桶的方法。
我怎样才能实现它?
