执行GCS图像上传步骤并从URL下载最新文件
https://developers.google.com/api-client-library/java/google-api-java-client/download下面是密码。
public class GcsExample {
private static GcsService gcsService = GcsServiceFactory.createGcsService();
// Error during initialization
public void doPost(String gcsFilename, byte[] data) throws IOException {
GcsFilename filename = new GcsFilename("niranttest2.appspot.com", gcsFilename);
com.google.appengine.tools.cloudstorage.GcsFileOptions.Builder fileOptionsBuilder = new GcsFileOptions.Builder();
fileOptionsBuilder.mimeType("image/jpeg");
GcsFileOptions fileOptions = fileOptionsBuilder.build();
GcsOutputChannel outputChannel = gcsService.createOrReplace(filename, fileOptions);
// write file out
BufferedOutputStream outStream = new BufferedOutputStream(Channels.newOutputStream(outputChannel));
List<byte[]> allBytes = new LinkedList<byte[]>();
allBytes.add(data);
for (byte[] b : allBytes) {
outStream.write(b);
}
outStream.close();
outputChannel.close();
}
}此代码在本地主机上运行良好，但在生产中gcsService没有初始化。服务器上的日志如下：

您似乎使用的是原始存储客户端(正如我从GcsServiceFactory.createRawGcsService中看到的)，我猜是因为您在App之外使用它。也许无论如何都是必需的。
这个类来自google-api-services-storage库，您应该添加以下依赖项：
<dependency>
<groupId>com.google.apis</groupId>
<artifactId>google-api-services-storage</artifactId>
<version>v1-rev66-1.21.0</version>
