element设置headers添加token

<template>
  <div>
    <el-upload
      action="http://localhost:3000/picture"
      :headers="headers"
      list-type="picture-card"
      :on-preview="handlePictureCardPreview"
      :on-remove="handleRemove">
      <i class="el-icon-plus"></i>
    </el-upload>
    <el-dialog :visible.sync="dialogVisible">
      <img width="100%" :src="dialogImageUrl" alt="">
    </el-dialog>
 </div>
</template>
<script>
  export default {
    data() {
      return {
        dialogImageUrl: '',
        dialogVisible: false,
        headers:{}
      };
    },
    methods: {
      handleRemove(file, fileList) {
        console.log(file, fileList);
      },
      handlePictureCardPreview(file) {
        this.dialogImageUrl = file.url;
        this.dialogVisible = true;
      }
    },
    created(){
      this.$http.get('/picture')
      this.headers ={Authorization : 'Bearer '+(localStorage.token || '')}
    }
  }
</script>
 
1,在data中创建headers对象
2,element中动态绑定headers
3,   created中赋值
