com.amazonaws.services.s3.model.AmazonS3Exception:必须指定用户密钥

Question

com.amazonaws.services.s3.model.AmazonS3Exception: User key must be specified. (Service: Amazon S3; Status Code: 400;
       at com.amazonaws.http.AmazonHttpClient.handleErrorResponse(AmazonHttpClient.java:1160)
       at com.amazonaws.http.AmazonHttpClient.executeOneRequest(AmazonHttpClient.java:748)
       at com.amazonaws.http.AmazonHttpClient.executeHelper(AmazonHttpClient.java:467)
       at com.amazonaws.http.AmazonHttpClient.execute(AmazonHttpClient.java:302)
       at com.amazonaws.services.s3.AmazonS3Client.invoke(AmazonS3Client.java:3769)
       at com.amazonaws.services.s3.AmazonS3Client.deleteObjects(AmazonS3Client.java:1841)

代码如下所示:

client.deleteObjects(new DeleteObjectsRequest(bucketName).withKeys(keys.toArray(new String[urls.length]))

访问/密钥设置正确.

什么是用户密钥？

Answer 1

如果 url 比键长，您将提交一个比键的大小长且包含空条目的数组，这可能会导致异常（我自己没有尝试过）。

您可能会想要：

client.deleteObjects(new DeleteObjectsRequest(bucketName)
    .withKeys(keys.toArray(new String[keys.length]))
