如何通过 id 获取用户并通过 get 请求使用 React Native 来表达？

问题描述

I am trying to render One users info for the profile page in react native using express and axios.我正在尝试使用 express 和 axios 在本机反应中呈现个人资料页面的一个用户信息。

This is the controller responsible for getting a user.这是负责获取用户的 controller。

```// GET ONE USER BY ID
module.exports.findOneSingleUser = (req, res) => {
User.findOne({ _id: req.params.id })
    .then(oneSingleUser => res.json({ user: oneSingleUser }))
    .catch(err => res.json({ message: 'Something went wrong', error: err }));
}```

this is the code im using to make the axios request to the server and I am able to get all the users in the DB but I want to be able to render one user by id or the token that is stored for login and for login to persist which is working.这是我用来向服务器发出 axios 请求的代码，我能够获取数据库中的所有用户，但我希望能够通过 id 或存储用于登录和登录的令牌呈现一个用户坚持这是有效的。

```
const ProfileInfo = (props) => {
const { navigation, route } = props
const authCtx = useContext(AuthContext);
const token= authCtx.token

const [userInfo, setUserInfo] = useState([]);


useEffect(() => {
    axios.get(`http://localhost:3000/api/users/`)
        .then(res => console.log(res.data))
        .catch(err => console.log(err))
}, [])```

this is the code in util folder that gets the token from the backend这是从后端获取令牌的 util 文件夹中的代码

import { useNavigation } from '@react-navigation/native';
const BASE_URL = 'http://localhost:3000'


    // ! LOGIN FUNCTION
    export async function authenticate(email,password ){
    const token = await axios.post(BASE_URL + '/api/login',
    {
        email: email,
        password: password,
    },{ withCredentials: true }
    );
    return token;
    }
    // ! REGISTER NEW USER FUNCTION
    export async function createUser(email, password) {
    const token = await axios.post(BASE_URL + '/api/register',
        {
            email: email,
            password: password,
        },{ withCredentials: true }
    );
    return token;

    }```


this is the screen where I have the profile info componet being used

    ```import React,{useEffect} from 'react'
    import ProfileInfo from '../components/Profile/ProfileInfo';
    import Statistics from '../components/Profile/Statistics';


    const ProfileScreen = (props) => {
    const {navigation} = props
    
    
    return (
        <>
            <ProfileInfo navigation={navigation}/>
            <Statistics />
        </>
    )
    }

    export default ProfileScreen```

    

How do or What do I need to pass into the url of the axios request to get the data for the user that is logged in?  thanks in advance.

when I change the server side to
    User.findOne({ token: req.params.token})

      &

    ``` useEffect(() => {
        axios.get(`http://localhost:3000/api/users/${token}`)
            .then(res => console.log(res.data))
            .catch(err => console.log(err))
    }, [])```


I get a user but it is only the first user in DB not the user that is logged in... not sure how to get the one user that is logged in.
