 this.$axios
        .get('/searchRoomTags', {
          params: {
            pageSize: this.roomPageInfo.pageSize,
            roomType: encodeURI(this.roomForm.roomType),
            roomTags: this.searchRoomTags,
            roomState: this.searchContent
          }
        })
        .then(Response => {
          if (Response.data) {
            this.searchSuccessHandle(Response)
          }
        })

Vue axios.get get请求如何传递数组对象？

我想将前端的get请求传递一个数组参数，但是报以下错误：

Vue axios.get get请求如何传递数组对象？

后台代码：

@CrossOrigin
    @GetMapping("/searchRoomTags")
    @ResponseBody
    public PageInfo<Rooms> searchRoomTags(@RequestParam String[] roomTags, Rooms room, HttpServletRequest request) {
        logger.info("用户开始根据房间标签进行查找————————");
        request.getSession().removeAttribute("condition");
        room.setCurrentPage(1);
        System.out.println("roomTags：" + roomTags);
//        PageInfo<Rooms> pageInfo = roomsServiceImpl.findRoomTags(room, roomTags);
        PageInfo<Rooms> pageInfo = null;
        logger.info("客房查询成功！");
        return pageInfo;
    }

报了如下错误：

替换成

 this.$axios
        .get('/searchRoomTags', {
          params: {
            pageSize: this.roomPageInfo.pageSize,
            roomType: encodeURI(this.roomForm.roomType),
            roomTags: (this.searchRoomTags || []).join(','),
            roomState: this.searchContent
          }
        })
        .then(Response => {
          if (Response.data) {
            this.searchSuccessHandle(Response)
          }
        })

回答：

数组的用Array.toString()转一下
[1,2,3,4].toString() => 1,2,3,4

回答：

url参数传数组并没有标准
servlet的逻辑是

  1. 逗号分隔，name=1,2,3
  2. 多个同名参数， name=1&name=2&name=3

建议换post传json，一劳永逸
