【vue】AntDV组件库中a-upload实现文件上传：

---

一、文档：

Upload 上传–Ant Design Vue

二、使用(以Jeecg为例)：

【1】template：

<a-upload name="file" :showUploadList="false" :multiple="false" :headers="tokenHeader"
	 :data="{ 'orderId': record.id }" :action="importExcelUrlDispatchCar"
   @change="handleImportExcel">导入
</a-upload>

【2】script：

<script>
 	export default {
  	data() {
    	return {
        
        url:{
           importExcelUrlDispatchCar:"/kd/xxx/importTemplate"
        }
      }
    },
    computed: {
        //拼接上传的地址
        importExcelUrlDispatchCar: function () {
          return `${window._CONFIG['domianURL']}/${this.url.importExcelUrlDispatchCar}`;
        },
      	// 设置上传的Header参数
      	tokenHeader() {
         	let head = { 'X-Access-Token': Vue.ls.get(ACCESS_TOKEN) }
          let tenantid = Vue.ls.get(TENANT_ID)
          if (tenantid) {
            head['tenant-id'] = tenantid
          }
      		return head;
      	},
    },
    methods:{
      handleImportExcel(info){
        this.loading = true;
      	if (info.file.status !==  'uploading') {
           console.log(info.file,  info.fileList);
        }
      	if (info.file.status === 'done') {
          this.loading = false;
          if (info.file.response.success){
          	if (info.file.response.code === 201) {
            	let { message, result:{ msg, fileUrl, fileName } }= info.file.response
            	let href = window._CONFIG['domianURL'] + fileUrl
            	this.$warning({
              	title: message,
             		content: (<div><span>{msg}</span>

                	<span>具体详情请 
                	<a href={href}target="_blank" download={fileName}>点击下载</a> 
                	</span></div>)
            	})
           	} else {
             	this.$message.success(info.file.response.message ||`${info.file.name} 文件上传成功`)
           	}
          	this.loadData()
          } else {
            this.$message.error(`${info.file.name} ${info.file.response.message}.`);
          }
        }else if (info.file.status === 'error') {
          this.loading = false;
          if (info.file.response.status === 500) {
          	let data = info.file.response
            const token = Vue.ls.get(ACCESS_TOKEN)
            if (token && data.message.includes("Token失效")) {
              this.$error({
                title: '登录已过期',
                content: '很抱歉，登录已过期，请重新登录',
                okText: '重新登录',
                mask: false,
                onOk: () => {
                  store.dispatch('Logout').then(() => {
                    Vue.ls.remove(ACCESS_TOKEN)
                    window.location.reload();
                  })
                }
              })
            }
          }
        }else{
          this.$message.error(`文件上传失败: ${info.file.msg} `);
        }
      },
    }
	}
