我正在尝试列出Google存储桶中一个目录中的所有文件 并且从每个文件读取数据,对于一些它正在工作但是 对于一个桶,它会抛出错误

  

引起:   com.google.api.client.googleapis.json.GoogleJsonResponseException:500   内部服务器错误{“code”:500,“errors”:[{“domain”:   “global”,“message”:“内部错误”,“原因”:“responseTooLarge”   }],“message”:“内部错误”

答案 0 :(得分:1)

好吧,假设第22行(​​错误的出处)就是那一行:

System.out.println("Blob name:"+blob.getName());

blob中的属性“ name”可能足够大,足以破坏应用程序。但是我几乎可以确定这不是应用程序损坏的地方。

基于类似的问题GoogleJsonResponseException: 500 Internal Server Error : Response Too Large To Return,我建议您创建一个错误,因为这可能是与Google库直接相关的问题。
