'Unknown authentication strategy' 在服务器中使用 TS 时出错

Question

我相信一切都已配置好，我没有遇到任何编译错误，并且寄存器按预期工作。

我看到一些 require('passport-local')(passport) 解决了它，但它不起作用。也不将身份验证方法更改为 local-login

Answer 1

import * as passportService from './config/passport';

TypeScript 将省略该导入，因为您没有使用任何 config/passport 正在导出（实际上您根本没有从该模块导出任何内容）的值位置。参见 https://github.com/Microsoft/TypeScript/issues/2812 和类似内容。

如果您查看 router.ts 的转译输出，您会发现它确实缺少 require('./config/passport')。解决方法是从该模块导出一些东西然后引用它——也许在导出的 init() 函数中初始化护照身份验证策略。

Answer 2

我知道我迟到了，但无论如何我都会提供我的建议，以防其他需要它的人找到他们的路。

根据www.typescriptlang.org：

Though not recommended practice, some modules set up some global state that can be used by other modules. These modules may not have any exports, or the consumer is not interested in any of their exports. To import these modules, use: import "./my-module.js";

在你的情况下应该这样做：

    import './config/passport';

将执行passport.ts的所有内容
