后端,根据id查询投票帖子信息：

/**
 * 根据id查询
 * @param id
 * @return
 */
@GetMapping("/{id}")
public R findById(@PathVariable(value = "id")Integer id){
    Vote vote = voteService.getById(id);
    WxUserInfo wxUserInfo = wxUserInfoService.getOne(new QueryWrapper<WxUserInfo>().eq("openid", vote.getOpenid()));
    vote.setWxUserInfo(wxUserInfo);
    List<VoteItem> voteItemList = voteItemService.list(new QueryWrapper<VoteItem>().eq("vote_id", id));
    vote.setVoteItemList(voteItemList);
    Map<String,Object> map=new HashMap<>();
    map.put("vote",vote);
    return R.ok(map);
}

映射加下：

registry.addResourceHandler("/image/coverImgs/**").addResourceLocations("file:D:\\uniapp\\coverImgs\\");
registry.addResourceHandler("/image/voteItemImgs/**").addResourceLocations("file:D:\\uniapp\\voteItemImgs\\");

新建帖子页面

	{
		"path": "pages/vote/vote",
		"style": {
			"navigationBarTitleText": ""
		}
	},

投票列表页面投票项 加下onclick点击跳转帖子页面

		goVotePage:function(voteId){
			uni.navigateTo({
				url:"/pages/vote/vote?id="+voteId
			})
		}
