【问题描述】：

操作系统：Windows 10 专业版 浏览器：Opera 47.0.2631.71 (PGO) 阿波罗客户端：1.9.2 订阅-传输-ws：0.6.0 Vue：2.4.2 vue-apollo: 2.1.0-rc.5

因此，我在尝试使用 graphcool 端点运行查询时遇到了上述错误。仅在尝试对新创建的链接项目进行投票时才会出现此问题。这里有什么问题？

完整的错误是：

查询：

export const ALL_LINKS_QUERY = gql`
query AllLinksQuery($first: Int, $skip: Int, $orderBy: LinkOrderBy) 
  allLinks(first: $first, skip: $skip, orderBy: $orderBy) 
    id
    createdAt
    url
    description
    postedBy 
      id
      name
    
    votes 
      id
      user 
        id
      
    
  
  _allLinksMeta 
    count
  

`

代码：

      voteForLink () 
        const userId = localStorage.getItem(GC_USER_ID)
        const voterIds = this.link.votes.map(vote => vote.user.id)
        if (voterIds.includes(userId)) 
          alert(`User ($userId) already voted for this link.`)
          return
        
        const linkId = this.link.id
        this.$apollo.mutate(
          mutation: CREATE_VOTE_MUTATION,
          variables: 
            userId,
            linkId
          ,
          update: (store,  data:  createVote  ) => 
            this.updateStoreAfterVote(store, createVote, linkId)
          
        )
      ,
      updateStoreAfterVote (store, createVote, linkId) 
        // 1
        const data = store.readQuery(
          query: ALL_LINKS_QUERY
        )

        // 2
        const votedLink = data.allLinks.find(link => link.id === linkId)
        votedLink.votes = createVote.link.votes

        // 3
        store.writeQuery( query: ALL_LINKS_QUERY, data )
      

【参考方案1】：

好的，问题已通过将变量与 ALL_LINKS_QUERY 调用关联起来解决：

        const data = store.readQuery(
          query: ALL_LINKS_QUERY,
          variables: 
            first: 5,
            skip: 0,
            orderBy: 'createdAt_DESC'
          
        )

老兄，你救了我！对于遇到此问题的任何人，请记住您还必须将 variables 传递给 writeQuery
