信息参数是阿波罗GraphQL解析器类型签名空(info argument is empty in

我工作的这个库https://github.com/ilyaskarim/wertik-js叫Wertik JS做GraphQL + REST API更容易，在解析器，当我控制台日志info ，它表明不确定的。 对于每个模块，我创建动态解析器​​，以使事情更容易为开发商谁将会使用这个库。

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);
      }
    },
}

行： https://github.com/ilyaskarim/wertik-js/blob/ec813f49a14ddd6a04680b261ae4ef2aadc2b1a5/src/framework/dynamic/resolvers.ts#L102

在阿波罗服务器文档中描述的信息https://www.apollographql.com/docs/apollo-server/essentials/data/#resolver-type-signature ，它说：这个自变量包含有关查询的执行状态信息，包括字段名，从根的路径，场，等等。 对我来说，不幸的是，它越来越不确定。

要重现该问题：

1. 下载https://github.com/ilyaskarim/wertik-js/tree/development
2. 纱线安装
3. 转到例子/演示
4. 运行node index.js
5. 现在去的http：//本地主机：1209 /

6. 输入此突变，例如：

   突变{CREATEROLE（输入：{名： “性Asd”}）{名称}}

7. 该行执行这一突变https://github.com/ilyaskarim/wertik-js/blob/ec813f49a14ddd6a04680b261ae4ef2aadc2b1a5/src/framework/dynamic/resolvers.ts#L102
8. 并返回未定义的控制台上。

这就是我设置的应用程序：

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}`);
  });
}

可能是什么可能的原因？

Answer 1:

你截断由内而外的解析器接收到的参数此模块 。 如果你需要一个功能分配给某个对象的财产，这是好多了，只是不喜欢这样写道：

mutations: {
  [`create${moduleName}`]: mutations[`create${moduleName}`],
},

这不仅更简洁，但同时也意味着你没有无意中留下过一个参数，它是在这里发生了什么。
