【问题描述】:
如何使用 GraphQL Yoga 进行多个嵌套查询?
这是我的数据
{
"user": [{
"id": 1,
"name": "Thomas",
"comment_id": [1, 2, 3]
},
{
"id": 2,
"name": "Riza",
"comment_id": [4, 5, 6]
}
],
"comment": [{
"id": 1,
"body": "comment 1"
},
{
"id": 2,
"body": "comment 2"
},
{
"id": 3,
"body": "comment 3"
}
]
}
场景是我想查询一个特定用户及其所有 cmets,但该用户只存储了comment id。
这是我的代码
const { GraphQLServer } = require('graphql-yoga');
const axios = require('axios');
const typeDefs = `
type Query {
user(id: Int!): User
comment(id: Int!): Comment
}
type User {
id: Int
name: String
comment: [Comment]
}
type Comment {
id: Int
body: String
}
`;
const resolvers = {
Query: {
user(parent, args) {
return axios
.get(`http://localhost:3000/user/${args.id}`)
.then(res => res.data)
.catch(err => console.log(err));
},
comment(parent, args) {
return axios
.get(`http://localhost:3000/comment/${args.id}`)
.then(res => res.data)
.catch(err => console.log(err));
},
},
User: {
comment: parent =>
axios
.get(`http://localhost:3000/comment/${parent.comment_id}`)
.then(res => res.data)
.catch(err => console.log(err)),
},
};
const server = new GraphQLServer({ typeDefs, resolvers });
server.start(() => console.log('Server is running on localhost:4000'));
所需查询
{
user(id: 1) {
id
name
comment {
id
body
}
}
}
但是返回not found,因为axios命中的端点是http://localhost:3000/comment/1,2,3'
如何让它返回所有用户的 cmets? 谢谢大家!
