我正在一个新的Nest.js项目中,并且每当我尝试启动服务器时:
void dragUpdate(DragUpdateDetails d) {
// using d.delta you can then track the movement and implement your rotation updade here
}
我已经检查了文档并四处查看,但无法发现问题。 [ExceptionHandler] Nest can't resolve dependencies of the RestController (?). Please make sure that the argument dependency at index [0] is available in the RestModule context.
类将注入RestController
,该类由UsersService
导出并导入UsersModule
中。一切看起来都很好,但是没有用。
这是我的代码:
RestModule
:
app.module.ts
import { Module } from '@nestjs/common'
import { RestModule } from './rest/rest.module'
@Module({
imports: [
RestModule
]
})
export class AppModule { }
:
rest.module.ts
import { Module } from '@nestjs/common'
import { RestController } from './rest.controller'
import { UsersModule } from '../users/users.module'
@Module({
imports: [
UsersModule
],
controllers: [
RestController
]
})
export class RestModule { }
:
rest.controller.ts
import { Controller, Inject, Get } from '@nestjs/common'
import { UsersService } from '../users/users.service'
import { User } from '../users/user.interface'
@Controller()
export class RestController {
constructor (
@Inject()
private readonly usersService: UsersService
) { }
@Get()
async getAll (): Promise<User[]> {
return this.usersService.findAll()
}
}
:
users.module.ts
import { Module } from '@nestjs/common'
import { UsersService } from './users.service'
@Module({
providers: [
UsersService
],
exports: [
UsersService
]
})
export class UsersModule { }
:
users.service.ts
提前谢谢!

在您的RestController
类中,您必须从构造函数中删除@Inject()
:
constructor (
private readonly usersService: UsersService
) { }
@Inject()
可用于non-class-based provider tokens。
