我正在尝试将图像存储在Google Storage中，并通过他们的一个论坛找到了一些测试代码。
我已经添加了各种依赖关系，并希望逐步遍历代码，但是在走得很远之前，我遇到了这个异常。我应该补充一点，这是本地测试，没有使用appEngine，而且我已经在网上寻找各种资源，但是很茫然。
我找到的代码是（我已经修改了存储段名称和文件的网址）：
public static void test() throws IOException {
GcsService gcsService = GcsServiceFactory.createGcsService();
BlobstoreService blobstoreService = BlobstoreServiceFactory.getBlobstoreService();
GcsFileOptions options = new GcsFileOptions.Builder()
.mimeType(".jpg")
.acl("project-private")
.build();
String bucketName = "my_test_bucket";
String secureFilename = "https://helpx.adobe.com/uk/stock/how-to/visual-reverse-image-search/_jcr_content/main-pars/image.img.jpg/visual-reverse-image-search-v2_1000x560.jpg";
GcsFilename p_filename = new GcsFilename(bucketName, secureFilename);
GcsOutputChannel writeChannel = gcsService.createOrReplace(p_filename, options); //exception here
//writeChannel.write(ByteBuffer.wrap(image.getImageData()));
writeChannel.close();
BlobKey blobKey = blobstoreService.createGsBlobKey("/gs/" + p_filename.getBucketName() + "/" + p_filename.getObjectName());
ImagesService imageService = ImagesServiceFactory.getImagesService();
ServingUrlOptions servoptions = ServingUrlOptions.Builder.withBlobKey(blobKey).secureUrl(true);
String url = imageService.getServingUrl(servoptions);
}
调用createOrReplace时会发生异常。
例外是：
