[英]info argument is empty in Apollo GraphQL resolver type signature
I'm working on this library https://github.com/ilyaskarim/wertik-js called Wertik JS to make GraphQL + Rest API more easily, In resolvers, when I console log info
, it shows undefined. 我正在使用这个名为Wertik JS的库https://github.com/ilyaskarim/wertik-js来简化GraphQL + Rest API,在解析器中,当我控制台日志
info
,它显示未定义。 For each module, I have created dynamic resolvers to make things more easy for developers who will use this library. 对于每个模块,我都创建了动态解析器,以使使用该库的开发人员更轻松地进行操作。
let object = {
create: async (_:any, args:any, context:any,info: any) => {
console.log(info); // This will be undefined
let v = await validate(validations.create,args.input);
let {success} = v;
if (!success) {
throw new ApolloError("Validation error",statusCodes.BAD_REQUEST.number,{list: v.errors})
}
try {
let createModel = await model.create(args.input);
pubsub.publish(`${camelCase(moduleName)}Created`, { [`${camelCase(moduleName)}Created`]: createModel });
return createModel;
} catch (e) {
return internalServerError(e);
}
},
}

The info is described in Apollo Server Documentation https://www.apollographql.com/docs/apollo-server/essentials/data/#resolver-type-signature , Which says: This argument contains information about the execution state of the query, including the field name, the path to the field from the root, and more. 该信息在Apollo服务器文档https://www.apollographql.com/docs/apollo-server/essentials/data/#resolver-type-signature中进行了描述,其中说:该参数包含有关查询执行状态的信息,包括字段名称,从根到字段的路径等等。 For me, unfortunately, it is getting undefined.
对我来说,不幸的是,它变得不确定。
To reproduce the issue: 重现此问题:
node index.js
node index.js
Enter this mutation for example: 输入此突变,例如:
mutation { createRole(input: {name: "Asd"}) { name } } 变异{createRole(input:{name:“ Asd”}){name}}
This is how I setup the application: 这是我设置应用程序的方式:
const { ApolloServer } = require('apollo-server');
import mutations from "./loadAllMutations";
import queries from "./loadAllQueries";
import resolvers from "./loadAllResolvers";
import subscriptions from "./loadAllSubscriptions";
import schemas from "./loadAllSchemas";
import generalSchema from "./../helpers/generalSchema";
export default function (rootDirectory: string,app: any,configuration: object) {
let allMutations = mutations(rootDirectory);
let allQueries= queries(rootDirectory);
let allSchemas = schemas(rootDirectory);
let allResolvers = resolvers(rootDirectory);
let allSubscriptions = subscriptions(rootDirectory);
let {validateAccessToken} = require(`${rootDirectory}/framework/predefinedModules/user/auth`).default;
let mainSchema = `
${generalSchema}
${allSchemas}
type Subscription {
${allSubscriptions}
}
type Mutation {
${allMutations}
}
type Query {
${allQueries}
}
schema {
query: Query
mutation: Mutation
subscription: Subscription
}
`;
const server = new ApolloServer({
typeDefs: mainSchema,
resolvers: allResolvers,
context: async (a: any) => {
await validateAccessToken(a.req);
}
});
server.listen(1209).then(({ url, subscriptionsUrl }) => {
console.log(`Server ready at ${url}`);
console.log(`Subscriptions ready at ${subscriptionsUrl}`);
});
}
What could be a possible reason? 可能是什么原因?
You're truncating the parameters received by the resolvers inside this module . 您正在截断此模块中的解析器接收的参数。 If you need to assign a function to some object property, it's much better to just do it like this:
如果您需要将函数分配给某些对象属性,则最好像这样进行操作:
mutations: {
[`create${moduleName}`]: mutations[`create${moduleName}`],
},
This is not only more succinct, but it also means you don't risk accidentally leaving off a parameter, which is what happened here. 这不仅更简洁,而且还意味着您不必冒意外遗漏参数的风险,这就是这里发生的情况。
