嵌套服务器未连接到MongoDB云UnhandledPromiseRejectionWarning: MongoPars

Question

我的NestJS后端需要连接到mongodb云，我从这里遵循文档

终端出现以下错误:

我的app模块代码:

import { Module } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import { UsersModule } from './users/users.module';
import {MongooseModule} from '@nestjs/mongoose'
@Module({
imports: [UsersModule,MongooseModule.forRoot('mongodb+srv://[e-mail]/nest-js-db?retryWrites=true&w=majority')],
controllers: [AppController],
providers: [AppService],
})
export class AppModule {}

我仔细检查了我的用户名和密码，但它们是正确的，是否有必要对它们进行编码，或者为什么会出现错误，请解释一下。

Answer 1

确保您的用户名密码和在URI连接字符串中没有任何非法字符.

如果用户名或密码包含以下字符:

: / ? # [ ] @

这些字符必须使用百分比编码进行转换。
