GraphQL新手,我在通过GraphiQL发送查询时遇到问题。
这是我的schema.js
const graphql = require('graphql');
const _ = require('lodash');
const{
GraphQLObjectType,
GraphQLInt,
GraphQLString,
GraphQLSchema
} = graphql;
const users = [
{id:'23', firstName:'Bill', age:20},
{id:'47', firstName:'Samantha', age:21}
];
const UserType = new GraphQLObjectType({
name: 'User',
fields:{
id: {type: GraphQLString},
firstName: {type: GraphQLString},
age:{type: GraphQLInt}
}
});
const RootQuery = new GraphQLObjectType({
name: 'RootQueryType',
fields:{
user: {
type: UserType,
args:{
id: {type: GraphQLString}
},
resolve(parentValue, args){ // move the resolve function to here
return _.find(users, {id: args.id});
}
},
}
});
module.exports = new GraphQLSchema({
query: RootQuery
});
当我在graphiql上运行以下查询时:
query {
user {
id: "23"
}
}
我得到"语法错误GraphQL请求(3:9)预期名称,找到字符串",但我希望得到ID为#34; 23"的用户。
我错过了什么?
答案 0 :(得分:2)
你将你的论点值放在你的选择上,而不应该是
query {
user(id: “23”) {
id
firstName
age
}
}
的参数部分
