令牌在本地存储中时的私有路由[TypeScript] [英] PrivateRouting when Token in Local Storage [TypeScript]

问题描述

如果我成功登录，将返回身份验证令牌，该身份验证令牌存储在本地存储中.成功登录后，我要走私人路线.

If my login in successful, an authentication token is returned, which is stored in the local storage. Upon successful login, I want to go the a private route.

我找到了此代码Javascript代码段，但无法使它适用于Typescript.我没有任何isAuthenthicated属性.我该如何进行相应的修改?

I found this code Javascript snippet but I am unable to make it work for Typescript. I don't have any isAuthenthicated property yet. How could I modify this accordingly?

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，但由于我将令牌存储在本地存储中，因此无法解决我的情况.

There is a similar question but it doesn't answer my case since I'm storing the token in local storage.

推荐答案

这将放在您的index.tsx文件中:

This will go in your index.tsx file:

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}/>;
};

并在浏览器路由器/交换机中使用它:

And use this in the browser router/switch:

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