        let _jsid = that.$route.query.id;
        if(that.file.length > 0){
          that.loading2 = true;
          //创建 formData 对象
          let formData = new FormData();
          //向 formData 对象中添加文件
          formData.append('jsid', _jsid);
          //多个文件上传
          for(var i=0; i< that.file.length; i++){
           formData.append("uploadFile",that.file[i]);  // 文件对象
          } 
          let config = {
           headers: {
            'Content-Type': 'multipart/form-data'
           }
          }
          axios.post(that.http + "/shweb/gys/gysmsge/gysuploads.action", formData, {
                timeout: 10000,
                headers: {
                  'Content-Type': 'multipart/form-data'
                }
              }).then(function (rdata) {
                that.loading2 = false;
                if(rdata.data == "0"){
                  that.islook = false;
                  that.islookshenghe = true;
                }
                console.log(rdata);
              }).catch(function (error) {
                that.loading2 = false;
               that.$Message.error('服务器错误' + error);
              });
        }else{
          that.$Message.error("请至少上传一个文件");
