React Native 如何獲取 cookie

Question

我有一個基於 cookie 的身份驗證系統，但我不明白如何從 react native/expo 獲取 cookie。 我使用js-cookie庫來管理 cookie。

請求方法：

async  postData(url = '', data) {
      // Default options are marked with *
      const response = await fetch(url, {
        method: 'POST', // *GET, POST, PUT, DELETE, etc.
        mode: 'cors', // no-cors, *cors, same-origin
        cache: 'no-cache', // *default, no-cache, reload, force-cache, only-if-cached
        credentials: 'same-origin', // include, *same-origin, omit
        headers: {
          'Content-Type': 'application/json',
          "CSRF-Token": Cookies.get("XSRF-TOKEN")
        },
        redirect: 'follow', // manual, *follow, error
        referrerPolicy: 'no-referrer', // no-referrer, *no-referrer-when-downgrade, origin, origin-when-cross-origin, same-origin, strict-origin, strict-origin-when-cross-origin, unsafe-url
        body: JSON.stringify({data}) // body data type must match "Content-Type" header
      });

      return response.json(); // parses JSON response into native JavaScript objects
}

當我consoloe.log(Cookies.get("XSRF-TOKEN"))它顯示undefined 。

這是我的快遞后端：

app.use(csrf({cookie: true}))
app.use("*", (req, res, next)=>{
    res.cookie("XSRF-TOKEN", req.csrfToken());
    next();
})

To get cookies in an expo project, you will first have to eject and then you can access the cookies for Android and iOS separately, as expo does not have any module that can help you get cookies.
