vue阿里上传图片报400错误

首先我用vue上传阿里图片用的是分片上传,分片上传由于一片是以100kb为起始的,所以当图片大小小于100kb的时候不分片,可以正常上传,当大于100kb的时候,会报400错误如下

One or more of the specified parts could not be found or the specified entit

当报这个错误时你要去登录阿里后台设置一下

文档地址:https://help.aliyun.com/document_detail/32069.htm
exopose header 要设置为 ETag

设置如下图vue阿里上传图片报400错误vue阿里上传图片报400错误

当你设置好了之后发现大于100kb也可以上传了,只不过阿里返回的图片链接格式有所不同

大于100kb的图片链接?后面带了一些参数你要截取vue阿里上传图片报400错误

下面是我的代码,运用了element组件库,包含了图片上传阿里,图片压缩
