我最近开始使用 Astro,对如何在框架内正确使用 React 组件感到有点困惑。我确信我的错误可能是一个愚蠢的错误,我不是专业的开发人员,这对我来说都是新的。
我的导航栏不起作用。当我单击移动菜单按钮时,没有任何反应,并且在页面加载时,我收到以下错误:
[Error] [astro-island] Error hydrating /src/components/Navbar.tsx Error: Missing Supabase URL or anon key Module Code — supabase.ts:7 (anonymous function) (localhost:1171:3738)
这是我的导航栏组件:
import { useState, useEffect } from "react";
import { Menu, X, User, LogOut } from "lucide-react";
import { Button } from "@/components/ui/button";
import {
DropdownMenu,
DropdownMenuContent,
DropdownMenuItem,
DropdownMenuTrigger,
} from "@/components/ui/dropdown-menu";
import { Avatar, AvatarFallback, AvatarImage } from "@/components/ui/avatar";
import { supabase } from "@/lib/supabase";
export const Navbar = () => {
const [open, setOpen] = useState(false);
const [loggedIn, setLoggedIn] = useState(false);
const checkUser = async () => {
const session = await supabase.auth.getSession();
if (session) {
setLoggedIn(true);
} else {
setLoggedIn(false);
}
};
checkUser();
return (

我的 .env 文件已正确设置,我的 .lib/supabase.ts 文件如下:
import { createClient } from "@supabase/supabase-js";
const supabaseUrl = import.meta.env.SUPABASE_URL;
const supabaseAnonKey = import.meta.env.SUPABASE_ANON_KEY;
if (!supabaseUrl || !supabaseAnonKey) {
throw new Error("Missing Supabase URL or anon key");
}
export const supabase = createClient(supabaseUrl, supabaseAnonKey);
我真的很感激这里的任何指点。
来自 Astro:使用环境变量:
请注意,虽然所有环境变量都可在服务器端代码中使用,但出于安全目的,只有前缀为
的环境变量可在客户端代码中使用。PUBLIC_
所以应该是:
const supabaseUrl = import.meta.env.PUBLIC_SUPABASE_URL;
const supabaseAnonKey = import.meta.env.PUBLIC_SUPABASE_ANON_KEY;
是的,这两个是可以安全地暴露在客户端,假设:
您已启用行级安全性。
