vue el-upload上传图片到七牛

一、思路，从后台获取七牛token，上传图片到七牛，获取返回图片路径放入el-upload。

二、代码。

<el-input v-model="listVideoQuery.orgLogo"  @change="orgLogoChange"></el-input>
          <el-col :span="10" class="mt10">
            <el-upload class="upload-demo" :file-list="fileList2" :action="domain" :before-upload="beforeAvatarUpload" :data="form"
              :on-remove="handleRemoveQrgLogo" :on-success="handleAvatarSuccess" list-type="picture" :limit="1" multiple>
              <el-button size="small" type="primary" @click="upPicName='orgLogo'">点击上传</el-button>
              <div slot="tip" class="el-upload__tip">只能上传jpg/png文件，且不超过500kb</div>
            </el-upload>
          </el-col>

export default {
    name: 'edit',
    data() {
      return {
        upPicName:'',  //上传图片名字
        fileList1:[],
        form: {}, //上传到七牛的token 
        bucketQuery:{
          bucket: 'website-image'  //这是我用来获取token传给后台的字段
        },
        domain: 'http://upload.qiniu.com',  // 七牛云的上传地址
        qiniuaddr: 'pd6rnk9ck.bkt.clouddn.com'  // 这是七牛云空间的外链默认域名
      }
    },
    methods: {
      // 上传图片规格
      beforeAvatarUpload (file) {
        const isJPG = file.type === 'image/jpeg' || file.type === 'image/png'
        const isLt2M = file.size / 1024 / 1024 < 5
        if (!isJPG) {
          return this.$message.error('上传文件只能是  JPG或PNG 格式!')
        }
        if (!isLt2M) {
          return this.$message.error('上传图片大小不能超过 5MB!')
        }

        return upQiniu(this.bucketQuery).then(res => {
          this.form = {
            token:res.data
          }
        })
        
      },
      //图片改变及上传
      bannerPicChange(value) {
        this.fileList1 = []
        this.fileList1.push({
          name: value, 
          url: value
        })   
      },
      handleBannerPicRemove(file, fileList) {
        this.fileList1 = []
        this.listVideoQuery.orgLogo= ''
      },
     handleAvatarSuccess(response) {
        if(this.upPicName =='orgLogo'){
          this.fileList1 = []
          this.fileList1.push({
            name: 'http://' + this.qiniuaddr + '/' + response.key, 
            url: 'http://' + this.qiniuaddr + '/' + response.key
          }) 
          this.listVideoQuery.orgLogo= 'http://' + this.qiniuaddr + '/' + response.key
        }
        this.$message({
          type: 'success',
          message: '上传成功!',
          duration: 2000
        })  
      },
    }
  }

三、效果。
