我遇到的问题似乎并不罕见,但是我发现的解决方案在我的项目中不起作用。
我想做的是使用护照进行简单的身份验证,如本教程所示:https://docs.nestjs.com/techniques/authentication
我一直遵循本教程,起初它是有效的。后来我决定使用用户的电子邮件和密码代替用户名作为身份验证。因此,我在身份验证过程中将变量名和参数更改为电子邮件,这就是一切都破裂的地方。我在这里想念东西吗?

async validateUser(email: string, pass: string): Promise<User | undefined> {
/**
* The findOne-method sends a database query
* to my mongodb via mongoose.
* I don't think it's necessary to post the UserService here, is it?
*/
const user: User = await this.usersService.findOne(email);
return this.encryptionService.compare(pass, user.password).then((result) => {
if (result) {

strategies / local.strategy.ts
import {Injectable, UnauthorizedException} from "@nestjs/common";
import {PassportStrategy} from "@nestjs/passport";
import {Strategy} from "passport-local";
import {AuthService} from "../services/auth.service";
@Injectable()
export class LocalStrategy extends PassportStrategy(Strategy) {
constructor(private authService: AuthService) {
super();
}
async validate(email: string, password: string): Promise<any> {
const user = await this.authService.validateUser(email, password);
if (!user) {
throw new UnauthorizedException();
}
return user;
}
}
guards / local-auth.guard.ts
import {Injectable} from "@nestjs/common";
import {AuthGuard} from "@nestjs/passport";
@Injectable()
export class LocalAuthGuard extends AuthGuard('local') {
}
根据this question,我发现validate-methods签名必须具有与请求有效负载密钥相同的参数名称。
出于调试目的,我在console.log()
的validate方法的第一行进行了一次strategies/local.strategy.ts
调用,但似乎根本没有调用。
感谢您提前提出任何答案。 有一个好吧!

对我来说,在创建 LocalStrategy 时,我将 {usernameField: 'email'}
传递给了 ParentClass。
如果您想使用“电子邮件”等自定义列检查用户身份验证,请尝试通过它。
我的 user.entity.ts:
@Entity()
export class User {
@PrimaryGeneratedColumn()
id: number;
@Column({ unique: true })
email: string;
@Column()
name: string;
}
我的 local.strategy.ts:
@Injectable()
export class LocalStrategy extends PassportStrategy(Strategy) {
constructor(private authService: AuthService) {
super({ usernameField: 'email' });
}
async validate(email: string, password: string): Promise<User> {
console.log(email, password); // it works
}
}

好吧,我自己解决了。 5个小时的调试浪费了! 原来,我的邮递员以某种方式没有随请求发送Content-Type标头。重新启动Postman修复了它。
