Question

尝试使用服务帐户凭据将内容发送到Google Cloud时出错

我们为项目目的创建了一个存储桶。

我创建了一个Java服务，尝试将JSON内容发送到存储桶。

我正在使用内置库将内容发送到存储桶。

我已附加了文档中提到的JARS和一个简单的4行代码，以将文件内容发送到存储桶。

根据文档的建议，我几乎遵循了下面的GITHUB链接。

但是我不确定我是否需要最新版本的jar，而文档中只提到了少数几个jar，例如（google-auth-library-oauth2-http，google-cloud-core，google-cloud -storage和google-auth-library-credentials），我不得不添加很多其他的jar来解决上述jar的依赖性错误。

https://cloud.google.com/docs/authentication/production#auth-cloud-explicit-java

https://github.com/GoogleCloudPlatform/java-docs-samples/blob/master/auth/src/main/java/com/google/cloud/auth/samples/AuthExample.java

Here is my code

    import com.google.auth.Credentials;
    import com.google.auth.oauth2.GoogleCredentials;
    import com.google.auth.oauth2.ServiceAccountCredentials;
    import com.google.cloud.storage.Blob;
    import com.google.cloud.storage.BlobId;
    import com.google.cloud.storage.BlobInfo;
    import com.google.cloud.storage.Storage;
    import com.google.cloud.storage.StorageOptions;

            Credentials credentials = GoogleCredentials.fromStream(new FileInputStream(keyPath));
                Storage storage = StorageOptions.newBuilder().setCredentials(credentials).build().getService();

            BlobId blobId = BlobId.of("tms-data", "test");  
                BlobInfo blobInfo = BlobInfo.newBuilder(blobId).setContentType("text/plain").build();
                Blob blob = storage.create(blobInfo, "Hello, Cloud Storage!".getBytes(("UTF-8")));

I have imported the following jars
