来自react-apollo- useMutation的钩子没有传递变量

Question

我正在将我的代码从apollo-boost重构到react-apollo-hooks，并且我一直收到以下错误：

Variable "$email" of required type "String!" was not provided
Variable "$password" of required type "String!" was not provided

我重构后的代码如下：

const [email, setEmail] = useState('')
const [password, setPassword] = useState('')
const variables = {
    data: { email, password }
}
const login = useMutation(LOGIN_MUTATION, {
    variables
})

const onSubmitHandler = async (login, e) => {
    e.preventDefault()
    const authResults = await login()
    localStorage.setItem(AUTH_TOKEN, authResults.data.login.token);
    props.history.push('/') 
}

graphql突变

const LOGIN_MUTATION = gql`
  mutation Login($email: String!, $password: String!) {
    login(data: {
        email: $email, password: $password
        }
    ){
      token
      user {
        id
      }
    }
  }
`

我的模式

login(data: LoginUserInput!): AuthPayload!

console.logging电子邮件和密码变量表示它们已正确传递到useMutation。

文档中有两个变量-- email和password。您实际传递给useMutation的是一个名为data的变量，该变量并不存在。

const variables = { email, password }
