Question

我有一个Java应用程序，需要知道它的实例ID。如何使用google-cloud-java库执行此操作？

在Go中，这非常简单：

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {

    guard let image1 = info[UIImagePickerController.InfoKey.originalImage]
        as? UIImage else {
            return
    }
    print(image1)
  //  firstImg.image = image1 as UIImage
    if addAttachBtn1.isSelected == true{
         firstImg.image = image1 as UIImage
    }else if addAttach2.isSelected == true{
        secondImg.image = image1 as UIImage
    }else if addAttach3.isSelected{
        thirdImg.image = image1 as UIImage
    }else if addAttach4.isSelected{
        fourthImg.image = image1 as UIImage
    }else{
        fifthImg.image = image1
    }

    dismiss(animated:true, completion: nil)
}

哦，我找到了它：https://github.com/googleapis/google-cloud-java/blob/969bbeef18f004fd51fd46c5def1ae5c644cae3c/google-cloud-clients/google-cloud-core/src/main/java/com/google/cloud/MetadataConfig.java#L52

String instanceId = com.google.cloud.MetadataConfig.getInstanceId()

google-cloud-java获取当前实例ID和区域
