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
})
}vote.vue
