有些人有命名問題，但似乎我在決議器和架構中使用相同。請告訴我，這是我在 GraphQL 和 Express 的第二天。我故意洗掉了快速物件、中間件的匯入和分配，因為它不允許我發布。
uj5u.com熱心網友回復：
我認為您只是缺少一個大括號。
const resolvers = {
Query:{
hello: () => 'Hello World',
notes: () => notes,
note: (parent, args) => {
return notes.find(note => note.id == args.id);
}
}, <==== THIS IS MISSING =====>
Mutation: {
newNote: (parent, args) => {
let noteValue = {
id : String(notes.length 1),
content : args.content,
author: 'Adam Scott',
};
notes.push(noteValue);
return noteValue;
}
}
