以上是页面代码
以下是逻辑代码，主要是对图片的校验，成功后的赋值，需要后台配合返回 保存的图片信息
{'file_name': file_, 'url': file_path}
beforeUpload(file){
const isJPG = file.type === 'image/jpeg' || file.type === 'image/png'
const isLt5M = file.size / 1024 / 1024 < 5
if (!isJPG) {
this.$message.error('上传图片只能是 JPG/PNG 格式!')
}
if (!isLt5M) {
this.$message.error('上传图片大小不能超过 5MB!')
}
return isJPG && isLt5M
},
handleSuccess(response) {
this.$message.success('上传成功!')
this.form.image = response.url;
},
handleRemove(){
this.$refs.upload.clearFiles()
},
