Minio报错Access denied 解决方案

java程序在调用Minio api报错信息如下

Error occurred: error occurred
ErrorResponse(code=AccessDenied, message=Access denied, bucketName=f3e0a479-60da-45c8-9ac2-5b744a92d419, objectName=null, resource=/f3e0a479-60da-45c8-9ac2-5b744a92d419, requestId=15E37CD9D06980DF, hostId=null)

解决方案：

1. 校验minio部署服务器的时间与程序运维主机时间是否相差太大，尽量保持一致

2. 若Minio服务器使用nginx进行代理，请检查nginx 是否按照如下标准的格式进行配置

server {
 listen 80;
 server_name example;  // 主机名
 location / {
   proxy_set_header Host $http_host;
   proxy_pass http://localhost:9000; // 你的Minio服务器地址
 }
}
