			 action:url,
      	     fileHeader: {
		        Authorization:token
		      },
		}
	},
	methods:{
		upload(event){
	       let files = event.target.files || event.dataTransfer.files;
	      if (!files.length) {
	          this.fileName = '';
	          return;
	      }
	      this.fileName = files[0].name;
	      // 上传之后调用接口...
	      let params = new FormData();
	      params.append('file', files[0]);
	      this.$refs.uploadFile.value = null;
	      request.post(url,params).then(
	          data => {
	           this.$message.success('上传文件成功！')
	          }
	        );
	        this.$refs.uploadFile.value = null; 
	    },
	    click () {//声东击西
	         this.$refs.uploadFile.click();
	    }
	}
}

      font-size: 1em;
      letter-spacing: 1px;
      text-shadow: rgba(0,0,0,0.9) 0px 1px 2px;
      background: #00a679;
      border: 1px solid #99e9d4;
      border-radius: 4px;
      box-shadow: rgba(255,255,255,0.25) 0px 1px 0px, inset rgba(255,255,255,0.25) 0px 1px 0px, inset rgba(0,0,0,0.25) 0px 0px 0px, inset rgba(255,255,255,0.03) 0px 20px 0px, inset rgba(0,0,0,0.15) 0px -20px 20px, inset rgba(255,255,255,0.05) 0px 20px 20px;
