vue上传图片到oss的方法示例(图片带有删除功能)

时间:2021-07-01 10:21:17 帮助过:7人阅读

最近Vue项目中,要将用户上传的图片全部上传到oss上,

OSS配置项请访问:https://help.aliyun.com/document_detail/64095.html?spm=a2c4g.11186623.6.773.kcD20n

OSS平台配置

在平台的概览里面看看自己的基础设置里面的读写权限是否改为了公共读,我这边只有配置公共读才上传并且回显图片成功,其他情况还请朋友告知,谢谢

关于跨域访问的配置

这里是我的效果图 (当只有点击上传按钮时才会上传到OSS)
