问题 I'm just getting to grips with GraphQL, I have set up the following query: ​ type: UserType, args: { id: { name: 'id', type: new GraphQLNonNull(GraphQLID) }, email: { name: 'email', type: new GraphQLNonNull(GraphQLString) } }, resolve: (root, { id, email }, { db: { User } }, fieldASTs) => { ... } I would like to be able to pass either an 'id' or 'email' to the query, however, with this setup it requires both an id and email to be passed.

问题 I have a mutation: const createSomethingMutation = gql` mutation($data: SomethingCreateInput!) { createSomething(data: $data) { something { id name } } } `; How do I create many Something s in one request? Do I need to create a new Mutation on my GraphQL server like this: mutation { addManySomethings(data: [SomethingCreateInput]): [Something] } Or is there a way to use the one existing createSomethingMutation from Apollo Client multiple times with different arguments in one request? 回答1: You

Next thing I am wondering about is how to add an addition messages object to the data object. Let's say The user has requested a database item by id (e.g. a

问题 I am trying to query a graphQL endpoint but I can't figure out what I am doing wrong. How am I supposed to set up the graphQL object to pass over. If I am trying to pass { name { age } } How should I be wrapping this to get the correct response from the server?
