php - 登录网址不适用于谷歌 PHP SDK

Question

我正在尝试创建登录名并注销我使用了这里的代码

https://developers.google.com/appengine/docs/php/users/loginurls?hl=vi

所以我的代码看起来像

    <?php
require_once 'google/appengine/api/users/User.php';
require_once 'google/appengine/api/users/UserService.php';


use google\appengine\api\users\User;
use google\appengine\api\users\UserService;

$user = UserService::getCurrentUser();

if (isset($user)) {
    echo sprintf('Welcome, %s! (sign out)',
        $user->getNickname(),
        UserService::createLogoutUrl('/'));
} else {
    echo sprintf('Sign in or register',
        UserService::createLoginUrl('/'));
}

和我的 app.yaml

application: test
version: 1
runtime: php
api_version: 1
threadsafe: true

handlers:
- url: /stylesheets
  static_dir: stylesheets

- url: /images
  static_dir: images

- url: /scripts
  static_dir: scripts

- url: .*
  script: main.php
  login: required
  auth_fail_action: redirect

当我使用 Google PHP SDK 1.8.1 在本地运行应用程序时，出现很多错误并且页面无法加载。

知道 SDK 中出现了什么问题。

当我从服务器运行应用程序时，它不会创建注销链接

Answer 1

您在 apppot 中看到的错误是因为您实际上并未在 html 中包含生成的链接。

比较示例：

'Welcome, %s! (<a href="%s">sign out</a>)'

使用您的代码：

'Welcome, %s! (sign out)'
