node.js - Graphql & Node 中未定义密码

问题描述

我正在尝试使用 GraphQL 和节点创建登录功能。我已经注册了工作，但是在查询登录功能时，它说密码没有定义。

AuthType

const AuthType = new GraphQLObjectType({
    name: 'Auth',
    fields: () => ({
        userId: {type: GraphQLString},
        username: {type: GraphQLString},
        email: {type: GraphQLString},
    })
});

这保存了我期待的数据。

const RootQuery = new GraphQLObectType({
  login: {
    type: AuthType,
    args: {
      password: {
        type: GraphQLString
      },
      email: {
        type: GraphQLString
      }
    },
    resolve(parent, args) {
      return User.findOne({
          email: args.email
        })
        .then(user => {
          const isEqual = new Promise(bcrypt.compare(password, args.password));
          if (!isEqual) {
            throw new Error('Password is incorrect!');
          }

        }).then(result => {
          return {
            userId: result.id,
            username: result.username
          };
        }).catch(err => {
          throw err
        });
    }
  }
});

这是检查数据的逻辑，谢谢。

schema.js

 const graphql = require('graphql');
    const bcrypt = require('bcryptjs');
    const jwt = require('jsonwebtoken');

    const {GraphQLObjectType, 
       GraphQLInt,
       GraphQLString,
       GraphQLSchema, 
       GraphQLID, 
       GraphQLList, 
       GraphQLNonNull } = graphql;

    const User = require('../models/user');
    const Event = require('../models/event');

用户类型定义了我们想要存储的用户数据。

const UserType = new GraphQLObjectType({
    name: 'User',
    fields: () => ({
        id: {type: GraphQLID},
        firstname: {type: GraphQLString},
        lastname: {type: GraphQLString},
        username: {type: GraphQLString},
        email: {type: GraphQLString},
        password: {type: GraphQLString},
        location: {type: GraphQLString},
        about: {type: GraphQLString},
        gender: {type: GraphQLString},
        yob: {type: GraphQLString},      //Year of Birth;
        events: {
            type: new GraphQLList(EventType),
            resolve(parent, args){
            //  return _.filter(events, {userId: parent.id});
                return Event.find({creator: parent.id});
            }
        }


    })
});

登录功能仍然无法识别密码输入。

解决方案

您没有在 中定义密码字段AuthType，我想您应该执行以下操作：

const AuthType = new GraphQLObjectType({
    name: 'Auth',
    fields: () => ({
        userId: {type: GraphQLString},
        username: {type: GraphQLString},
        email: {type: GraphQLString},
        password: {type: GraphQLString},
    })
});

此外，您在此行中有拼写错误：

const RootQuery = new GraphQLObectType({

它应该GraphQLObjectType代替GraphQLObectType

此外，在这一行中：

const isEqual = new Promise(bcrypt.compare(password, args.password));

可能您在那里遇到错误，因为password代码中没有定义。你大概想做什么user.password？
