1、自定义上传方法

editor.config.customUploadImg = (files, insert) => { this.uploadFn(files, insert) }

2、调用接口上传

async uploadFn (files, insert) {

        const file = new FormData()

        file.append('file', files[0])

        await post(`路径地址`,file).then(res => {

                insert(res.data.result)

        })

}
