Auth

原生移动深度链接

Set up Deep Linking for mobile applications.

许多认证方法都需要重定向到你的应用。例如：

🌐 Many Auth methods involve a redirect to your app. For example:

  • 注册确认邮件、Magic Link 登录和密码重置邮件都包含一个会将你重定向到应用的链接。
  • 在 OAuth 登录中，会自动重定向到你的应用。

通过深度链接，你可以配置这个重定向去打开一个特定的页面。例如，如果你需要显示一个重置密码的表单，或者手动交换一个令牌哈希，这是必要的。

🌐 With Deep Linking, you can configure this redirect to open a specific page. This is necessary if, for example, you need to display a form for password reset, or to manually exchange a token hash.

设置深度链接 #

🌐 Setting up deep linking

To link to your development build or standalone app, you need to specify a custom URL scheme for your app. You can register a scheme in your app config (app.json, app.config.js) by adding a string under the scheme key:

{
  "expo": {
    "scheme": "com.supabase"
  }
}

在你项目的认证设置中添加重定向网址，例如 com.supabase://**。

最后，实现 OAuth 和链接处理程序。有关在 React Native 中初始化 supabase-js 客户端的说明，请参阅 supabase-js 参考。

import { Button } from "react-native";
import { makeRedirectUri } from "expo-auth-session";
import * as QueryParams from "expo-auth-session/build/QueryParams";
import * as WebBrowser from "expo-web-browser";
import * as Linking from "expo-linking";
import { supabase } from "app/utils/supabase";
WebBrowser.maybeCompleteAuthSession(); // required for web only
const redirectTo = makeRedirectUri();
const createSessionFromUrl = async (url: string) => {
  const { params, errorCode } = QueryParams.getQueryParams(url);
  if (errorCode) throw new Error(errorCode);
  const { access_token, refresh_token } = params;
  if (!access_token) return;
  const { data, error } = await supabase.auth.setSession({
    access_token,
    refresh_token,
  });
  if (error) throw error;
  return data.session;
};
const performOAuth = async () => {
  const { data, error } = await supabase.auth.signInWithOAuth({
    provider: "github",
    options: {
      redirectTo,
      skipBrowserRedirect: true,
    },
  });
  if (error) throw error;
  const res = await WebBrowser.openAuthSessionAsync(
    data?.url ?? "",
    redirectTo
  );
  if (res.type === "success") {
    const { url } = res;
    await createSessionFromUrl(url);
  }
};
const sendMagicLink = async () => {
  const { error } = await supabase.auth.signInWithOtp({
    email: "valid.email@supabase.io",
    options: {
      emailRedirectTo: redirectTo,
    },
  });
  if (error) throw error;
  // Email sent.
};
export default function Auth() {
  // Handle linking into app from email app.
  const url = Linking.useLinkingURL();
  if (url) createSessionFromUrl(url);
  return (
    <>
      <Button onPress={performOAuth} title="使用 GitHub 登录" />
      <Button onPress={sendMagicLink} title="发送魔法链接" />
    </>
  );
}

为了获得最佳的用户体验，建议使用需要更复杂设置的通用链接。你可以在 Expo 文档 中找到详细的设置说明。
