Cookie 未包含在请求中 header / 服务器端无法读取 req.cookies

Question

我正在学习并为我的博客网站申请身份验证！

我正在使用 express-session 来处理登录。浏览器和服务器会话上的 Cookie 工作正常。

但是，我在 server-side 快递应用 上检索 cookie 时遇到问题。我尝试了以下方法：

与 cookie-parser、req.cookies 和 req.signedCookies 都 returns [Object: null prototype]。
设置 CORS
req.cookie & req.header.cookie returns undefined
我可以在浏览器网络选项卡的连接中看到“Cookie”header。

我的代码/设置如下：

function auth (req, res, next) {
  // Problem: Cannot read browser cookie of HTTP requests.
  console.log('Based on browser', req.cookie, req.cookies, req.signedCookies);
  next();
}

router.get('/', auth, async (req, res) => { // ... }

中间件

app.use(cors({
  origin: ['http://localhost:3000'],
  credentials: true
}));
app.use(cookieParser())  // Also tried with secret option.
app.use(session({
  secret: 'top-secret',
  resave: true,
  rolling: true,
  saveUninitialized: false,
  store: store, // this is working
  cookie: {
    maxAge: 1000 * 60 * 60 * 24 * 14,
    httpOnly: true,
    secure: process.env.NODE_ENV !== 'Development',
    sameSite: process.env.NODE_ENV === 'Development' ? 'lax' : 'none'
  }
}))

提前谢谢你:)

如果您只使用 http，您应该考虑两件事：

第一步在客户端请求时： 你应该像这样发送请求：

        const req = await fetch("http://localhost:7000/api/auth/login", {
      method: "POST",
      credentials: "include",
      headers: {
        "Content-Type": "application/json",
        "Access-Control-Allow-Credentials": true,
      },
      body: JSON.stringify({
        email: formData.get("email"),
        password: formData.get("password"),
      }),
    });
    const data = await req.json();

表达中的第 2 步：

const allowedOrigins = ["http://localhost:8000"];
    const corsOptions = {
    origin: function (origin, callback) {
   if (allowedOrigins.indexOf(origin) !== -1) {
  callback(null, true);
    } else {
     var msg =
    "The CORS policy for this site does not " +
    "allow access from the specified Origin.";
     callback(new Error(msg), false);
   }
 },
optionsSuccessStatus: 200,
 credentials: true,
 };
app.use(cors(corsOptions));

现在您可以使用 req.cookies.nameOfCookiesWhichYouSendThroughCoockieParser

快速获取 cookie

Cookie 未包含在请求中 header / 服务器端无法读取 req.cookies

Cookie is not included in request header / Server side cannot read req.cookies

javascript

node.js

express
