如何从graphql突变返回令牌

这是我的变更代码,其中我使用具有名称,电子邮件,密码的User类型,并且我对注册用户和登录用户进行了两种更改。我搜索了有关graphql的所有文档,并阅读了所有与身份验证相关的博客,但无法获得从变异中返回令牌的答案

    const mutation = new GraphQLObjectType({
      name: "Mutation",
      fields: {
        addUser: {
          type: UserType,
          args: {
            name: { type: GraphQLString },
            email: { type: GraphQLString },
            password: { type: GraphQLString },
            avatar: { type: GraphQLString }
          },
          resolve(parentValue, args) {
            const avatar = gravatar.url(args.email);
            return bcrypt
              .hash(args.password, 10)
              .then(hash => {
               args.password = hash;
               const newUser = new User({
                  name: args.name,
                  email: args.email,
                  password: args.password,
                  avatar
                });
                return newUser
                  .save()
                  .then(user => user)
                  .catch(e => e);
              })
               .catch(e => e);
          }
        },
        login: {
          name: "Login",

          type: UserType,
          args: {
            email: { type: GraphQLString },
            password: { type: GraphQLString }
          },
          resolve(parentValue, args, context) {
            return User.findOne({ email: args.email })
              .then(user => {
                if (user) {
                  return bcrypt
                    .compare(args.password, user.password)
                    .then(isValid => {
                      if (!isValid) {
                        throw new Error({ message: "password Incrrect" });
                      } else {
                        const token = jwt.sign(
                          { name: user.name, id: user.id },
                          "mySecret"
                        );
                        return user;
                      }
                    })
                    .catch(e => e);
                } else {
                  throw new Error({ message: "email Incorrect" });
                }
              })
              .catch(e => e);
          }
        }
      }
    });

这是我的用户类型

    const UserType = new GraphQLObjectType({
      name: "User",
      fields: {
        id: { type: GraphQLString },
        name: { type: GraphQLString },
        email: { type: GraphQLString },
        password: { type: GraphQLString },
        avatar: { type: GraphQLString }
      }
    });

我建议您通过删除密码字段并添加令牌字段来更新UserType,例如:

const UserType = new GraphQLObjectType({
      name: "User",
      fields: {
        id: { type: GraphQLString },
        name: { type: GraphQLString },
        email: { type: GraphQLString },
        avatar: { type: GraphQLString },
        token: { type: GraphQLString }
      }
 });

原因是UserType是突变的返回类型,因此它是“ public”,也许我们不应该向public发送密码(因为我们在服务器端进行身份验证),但是JWT是公开,所以我们可以将其发回。

然后在您的login变体中,将令牌添加到用户对象中,例如:

   login: {
      name: "Login",
      type: UserType,
      args: { email: { type: GraphQLString }, password: { type: GraphQLString } },
      resolve(parentValue, args, context) {
        return User.findOne({ email: args.email })
          .then(user => {
        .........
                    const token = jwt.sign(
                      { name: user.name, id: user.id },
                      "mySecret"
                    );
                    user.token = token;
                    return user;
                  }
        ........
      }
    }
