按照官方demo 使用mp-uploader 组件

https://developers.weixin.qq.com/miniprogram/dev/extended/weui/uploader.html

属性有max-size 默认值为 5*1024*1024 =5242880

现在我想把他设置为4*1024*1024 = 4194304

<mp-uploader bindfail="uploadError" max-count="1" bindsuccess="uploadSuccess" select="{{selectFile}}" upload="{{uplaodFile}}" files="{{files}}" title="营业执照" tips="请上传营业执照，图片不能超过4MB"></mp-uploader>

添加 max-size="4194304‬" 参数后

<mp-uploader bindfail="uploadError" max-size="4194304‬" max-count="1" bindsuccess="uploadSuccess" select="{{selectFile}}" upload="{{uplaodFile}}" files="{{files}}" title="营业执照" tips="请上传营业执照，图片不能超过4MB"></mp-uploader>

1. upload error {type: "fail", timeStamp: 180497, target: {…}, currentTarget: {…}, mark: {…}, …}
2. changedTouches: undefined
3. currentTarget: {id: "", dataset: {…}}
4. detail: {type: 1, errMsg: "chooseImage:fail size exceed 0", total: 1, index: 0}
5. mark: {}
6. mut: false
7. target: {id: "", dataset: {…}}
8. timeStamp: 180497
9. touches: undefined
10. type: "fail"
11. _requireActive: undefined
12. __proto__: Object

去掉 max-size="4194304‬" 就是正常的

求解原因？

本来想发代码片段的，报太大发不了，也是醉了
