leancloud-storage-sdk初始化 base64上传图片

 1、初始化sdk

import AV from "leancloud-storage"

AV.init({
  appId: "tBGTpuCzmDgW4KNgFS5dthcQ-gzGzoHsz",
  appKey: "QkhUqf2jRnME5pvHNmNezlIv",
  serverURL: "https://ejcadypa.lc-cn-n1-shared.com"
})

2、vue代码操作

<template>
  <el-upload class="avatar-uploader" :show-file-list="false" :on-success="handleAvatarSuccess"
    :http-request="handleUpload">
    <img v-if="imageUrl || ImgUrl" :src="imageUrl || ImgUrl" class="avatar" />
    <el-icon v-else class="avatar-uploader-icon">
      <Plus />
    </el-icon>
  </el-upload>
</template>

<script >
import { ref } from 'vue'
import { ElMessage } from 'element-plus'
import { Plus } from '@element-plus/icons-vue'
import AV from "leancloud-storage"
export default {
  props: {
    ImgUrl: String
  },
  data() {

    return {
      imageUrl: ''
    }
  },
  methods: {
    // 使用getBase64处理图片
    getBase64(img, callback) {
      const reader = new FileReader();
      reader.addEventListener('load', () => callback(reader.result));
      reader.readAsDataURL(img);
    },
    handleUpload(obj) {
      this.getBase64(obj.file, (base64) => {
        const data = { base64: base64 };
        const file = new AV.File("pic.png", data); //将本地的base64转化为leancloud资源
        file.save().then(res => {
          let { url } = res.attributes
          console.log(url);
          this.imageUrl = url
          this.$emit("setimg", url)
        })
      })
    },
    handleAvatarSuccess(response, uploadFile) {
      // imageUrl.value = URL.createObjectURL()
      // console.log(uploadFile);/

    }
  }
}

</script>
