[英]NestJS Nest can't resolve dependencies of the RolesService (+, +, ?)
[英]problem nestjs - Nest can't resolve dependencies of the AuthenticationService (?)
應用程序在啟動時立即停止,其他模塊尚未檢查,因此錯誤不太可能在其中。
認證服務.ts
import { HttpException, HttpStatus, Inject, Injectable } from '@nestjs/common';
import { CreateUserDto } from 'src/users/dto/createUser.dto';
import { UserService } from 'src/users/user/user.service';
import bcrypt from 'bcrypt';
@Injectable()
export class AuthenticationService {
constructor(@Inject() private readonly userService: UserService){}
public async regiser(registartionData:CreateUserDto){
const hashingPassword = await bcrypt.hash(registartionData.passwordHash, 10);
try{
const createUser = await this.userService.create({
...registartionData,
passwordHash: hashingPassword
})
createUser.passwordHash = undefined;
return createUser;
}
catch(err){
throw new HttpException('Something went wrong', HttpStatus.INTERNAL_SERVER_ERROR);
}
}
public async getAuthenticationUser(email:string, textPassword:string){
try{
const user = await this.userService.findByEmail(email);
await this.verifyPassword(textPassword,user.passwordHash);
user.passwordHash = undefined;
return user;
}
catch(err){
throw new HttpException('Wrong credentials provided', HttpStatus.BAD_REQUEST);
}
}
private async verifyPassword(password:string, hashingPassword:string){
const isMatching = await bcrypt.compare(password, hashingPassword);
if(!isMatching) throw new HttpException('Wrong credentials provided', HttpStatus.BAD_REQUEST);
}
}
auth.module.ts
import { Module } from '@nestjs/common';
import { PassportModule } from '@nestjs/passport';
import { UsersModule } from 'src/users/users.module';
import { AuthController } from '../controllers/auth/auth.controller';
import { AuthenticationService } from './authentication/authentication.service';
import { LocalStrategy } from './authentication/local.strategy';
@Module({
imports:[UsersModule, PassportModule, ],
providers: [AuthenticationService, LocalStrategy],
controllers:[AuthController],
exports: [AuthenticationService]
})
export class AuthModule {}
這個錯誤
Nest can't resolve dependencies of the AuthenticationService (?). Please make sure that the argument dependency at index [0] is available in the AuthModule context.
Potential solutions:
- If dependency is a provider, is it part of the current AuthModule?
- If dependency is exported from a separate @Module, is that module imported within AuthModule?
@Module({
imports: [ /* the Module containing dependency */ ]
})
我不明白錯誤,導出並提供身份驗證服務。 我不在其他模塊中使用身份驗證服務。
我所有的服務都使用mongodb model。因此,您需要在模塊和服務中進行以下操作。
用戶.module.ts
@Module({
*imports: [MongooseModule.forFeature([{ name: 'User', schema: UserSchema }])],*
providers: [UserService],
exports: [UserService],
})
export class UsersModule {}
用戶服務.ts
@Injectable()
export class UserService implements IUserService {
constructor(
*@InjectModel(User.name) private userModel: Model<User>*
) {}
很好的例子https://wanago.io/2021/08/23/api-nestjs-relationships-mongodb/
你的 repo 中的代碼甚至無法編譯,所以幾乎無法幫助你。 缺少東西,ts-errors 等。
但據我所知:
UserService
但它沒有導出它。 因此沒有其他模塊可以訪問它。 您還需要導出 UserService。imports: [UserModule]
(以及在 UserModule 中導出 UserService)。並再次閱讀模塊和示例項目的文檔,了解導入、導出、控制器和提供程序是如何工作的。
