Question

我正在构建Apollo服务器。我有一个与Mongo通信的简单端点。有一系列的公告。

export const typeDefs = gql`
  type Query {
    announcements: [Announcement]
    announcementsByAuthor(author: String!): [Announcement]
  }

  type Announcement {
    _id: ID!
    msg: String!
    author: String!
    title: String
  }
`;

export const resolvers = {
  Query: {
    announcements: () => {
      return new AnnouncementController().getAnnouncements();
    },
    announcementsByAuthor: (author: string) => {
      console.log('RESOLVER: ', author);
      return new AnnouncementController().getAnnouncementsByAuthor(author);
    }
  },
}

在我的graphiql界面中，公告查询正常工作：

{
  announcements {
    msg
    author
    }
}

announcesByAuthor查询似乎未从变量或将其硬编码到查询中时接受字符串参数。

query($author: String!){
  announcementsByAuthor(author: $author) {
    msg
    author
  }
}

变量：

{
  "author":"Nate"
}

我已经从解析器注销，正在传递一个空字符串，而不是author变量的指定值。我是graphql的新手，我希望有人能启发我有关我确信这是一个简单的疏忽。

Answer 1

尝试以下方法：

announcementsByAuthor: (doc, {author}) => {

Graphiql变量未传递到服务器
