Angular Apollo：錯誤：GraphQL 錯誤：“Mutation”類型的“AuthLogin”字段上的未知參數“用戶名”

Question

我的 angular 應用程序出現此錯誤，對 graphql 使用阿波羅

ERROR Error: GraphQL error: Unknown argument "username" on field "AuthLogin" of type "Mutation".

突變.ts

import gql from 'graphql-tag';

export const AuthLogin = gql`
  mutation($username: String, $password: String) {
    AuthLogin(username: $username, password: $password) {
      auth
    } 
  }`;

登錄組件.ts

import {AuthLogin} from '../mutations';

this.apollo.mutate({
        mutation: AuthLogin, variables: { username: this.username, password: this.password }
      }).subscribe( (data) => {
        console.log(data)
      });

后端架構.graphql

input LoginInput {
    username: String!
    password: String!
}

type Mutation {
    AuthLogin(data:LoginInput): AuthResolver
}

解決了！ data: {...此處缺少類型：

export const AuthLogin = gql`
  mutation AuthLogin($username: String!, $password: String!) {
    AuthLogin( data: {username: $username, password: $password} ) {
      auth
    } 
  }`;
