从req.body获取未定义

Question

当我调度startAddLike时，我在服务器端获取未定义的uid值，即。 req.body.uid = undefined.how来解决它？

动作发生器：

export const startAddLike = (id) => {
    return (dispatch, getState) => {
        const uid = getState().auth.uid;
        axios
            .post(`http://localhost:5000/api/posts/${id}/like`, uid)
            .then(res => dispatch(likePost(id, uid)))
    }
}

像邮政路线一样

router.post('/:id/like', (req, res) => {
    console.log(req.body.uid);
    Post.findOneAndUpdate({_id:req.params.id}, {$push: {likes: req.body.uid}},{ "new": true})
        .then(post => {
            console.log('l'+post);
            res.json(post);
        })
});

在这里，uid应该作为对象传递。

所以这应该是

export const startAddLike = (id) => {
    return (dispatch, getState) => {
        const uid = getState().auth.uid;
        axios
            .post(`http://localhost:5000/api/posts/${id}/like`, { uid: uid })
            .then(res => dispatch(likePost(id, uid)))
    }
}

希望能解决您的问题。
