uni-app 把图片资源转换成 Base64 字符串的 ArrayBuffer 对象，放在image的url上

this.path : 最终放在image的url里

<u-image :src="imgSrc"></u-image>

import storage from '@/utils/storage'
import { ACCESS_TOKEN} from '@/store/mutation-types'// 接口代码
uni.request({url: '接口地址',method: 'GET', data: {},header: {'Authorization':storage.get(ACCESS_TOKEN)},responseType: "arraybuffer",success: res => {const arrayBuffer = res.datathis.path = 'data:image/jpeg;base64,' + uni.arrayBufferToBase64(arrayBuffer)},fail: () => {},complete: () => {}})
