前几天接到一个需求,需要图片上传aws后可以直接公网访问,aws文件上传默认是不能直接访问,需要签名,这就不符合我们的场景,因为另外几个服务不想更新,只想读取图片路径
其实也就是在配置aws储存的时候记得开放公网访问即可
这一步不是我配置的,我们运维负责的,所以我也不知道怎么搞,所以直接在网上拿图吧
记得配置,不配置怎么玩都不行

下面就是代码了,点简单,看官网的文档就可以:https://docs.aws.amazon.com/zh_cn/sdk-for-php/v3/developer-guide/s3-presigned-url.html
说下环境把我用的php5.6
aws版本号:
"aliyuncs/oss-sdk-php": "2.3.0",
不要问选低版本,因为php5.6不支持高版本的,这里很坑
