本地存储中令牌时的 PrivateRouting [TypeScript]

Question

如果我登录成功，将返回一个身份验证令牌，该令牌存储在本地存储中。登录成功后，我想走私人路线。

我找到了这段代码 Javascript 片段，但我无法使其适用于 Typescript。我还没有任何 isAuthenthicated 属性。我该如何相应地修改它？

const PrivateRoute = ({ component: Component, ...rest }) => (
  <Route {...rest} render={props => (
    fakeAuth.isAuthenticated ? (
      <Component {...props}/>
    ) : (
      <Redirect to={{pathname: '/login', state: { from: props.location }
   }}/>
  )
 )}/>
)

这是我的登录屏幕：

const LoginMutation = gql`
mutation LoginMutation($email: String!, $password: String!) {
  loginEmail(email: $email, password: $password)
}
`;

const schema = Yup.object({
  email: Yup
    .string()
    .email('Invalid Email')
    .required('Please Enter your Email'),
  password: Yup
    .string()
    .required('Please Enter your password')
});

function LoginPage (){
  const [state, setState] = useState({
    email: '',
    password: '',
    loggedIn: false,
  });  


  function submitForm(LoginMutation: any) {
    const { email, password } = state;
    console.log(email, password)
    if(email && password){
      LoginMutation({
        variables: {
            email: email,
            password: password,
        },
    }).then(({ data }: any) => {
      localStorage.setItem('token', data.loginEmail);
    })
    .catch(console.log)

    }
  }

    return (
      <Mutation mutation={LoginMutation}>
        {(LoginMutation: any) => (
              <Typography component="h1" variant="h5">
                Sign in
              </Typography>
              <Formik
                initialValues={{ email: '', password: '' }}
                onSubmit={(values, actions) => {
                  setTimeout(() => {
                    alert(JSON.stringify(values, null, 2));
                    actions.setSubmitting(false);
                  }, 1000);
                }}
                validationSchema={schema}
              >
                {props => {
                  const {
                    values: { email, password },
                    errors,
                    touched,
                    handleChange,
                    isValid,
                    setFieldTouched
                  } = props;
                  const change = (name: string, e: any) => {
                    e.persist();                
                    handleChange(e);
                    setFieldTouched(name, true, false);
                    setState( prevState  => ({ ...prevState,   [name]: e.target.value }));  
                  };
                  return (
                    <form style={{ width: '100%' }} onSubmit={e => {e.preventDefault();submitForm(LoginMutation)}}>
                      <TextField
                        variant="outlined"
                        margin="normal"
                        id="email"
                        fullWidth
                        name="email"
                        helperText={touched.email ? errors.email : ""}
                        error={touched.email && Boolean(errors.email)}
                        label="Email"     
                        value={email}
                        onChange={change.bind(null, "email")}
                      />
                      <TextField
                        variant="outlined"
                        margin="normal"
                        fullWidth
                        id="password"
                        name="password"
                        helperText={touched.password ? errors.password : ""}
                        error={touched.password && Boolean(errors.password)}
                        label="Password"
                        type="password"
                        value={password}
                        onChange={change.bind(null, "password")}
                      />
                      <FormControlLabel
                        control={<Checkbox value="remember" color="primary" />}
                        label="Remember me"
                      />
                      <br />
                      <Button className='button-center'
                        type="submit"
                        disabled={!isValid || !email || !password}
                      >
                        Submit</Button>
                    </form>
                  )
                }}
              </Formik>
            </div>
          )
        }
      </Mutation>
    );
}

export default LoginPage;

有一个类似的问题，但它没有回答我的问题，因为我将令牌存储在本地存储中。

Answer 1

只需将 fakeAuth.isAuthenticated 替换为您保存的令牌，您也可以将其保存为全局状态，对吗？所以，一般来说，它只是一个布尔值属性来检查用户是否成功登录取决于用户将重定向到登录页面或受保护页面的情况

Answer 2

这将进入您的 index.tsx 文件：

const token = localStorage.getItem('token');

const PrivateRoute = ({component, isAuthenticated, ...rest}: any) => {
    const routeComponent = (props: any) => (
        isAuthenticated
            ? React.createElement(component, props)
            : <Redirect to={{pathname: '/login'}}/>
    );
    return <Route {...rest} render={routeComponent}/>;
};

并在浏览器中使用它 router/switch:

<PrivateRoute
    path='/panel'
    isAuthenticated={token}
    component={PrivateContainer}
/>
