使用注解的方式来开发 egg 中的 Controller
# tegg 注解
npm i --save @eggjs/tegg
# tegg 插件
npm i --save @eggjs/tegg-plugin
# tegg controller 插件
npm i --save @eggjs/tegg-controller-plugin
// tsconfig.json
{
"extends": "@eggjs/tsconfig"
}
// config/plugin.js
exports.tegg = {
package: '@eggjs/tegg-plugin',
enable: true,
};
exports.teggController = {
package: '@eggjs/tegg-controller-plugin',
enable: true,
};
Middleware 支持多个入参,依次传入要生效的中间件 中间件注解,可以添加在类/方法上。添加在类上时,对类上所有方法生效,添加在方法上时,只对当前方法生效。
// app/middleware/global_log.ts
import { Context } from 'egg';
import type { Next } from '@eggjs/controller-decorator';
export default async function globalLog(ctx: Context, next: Next) {
ctx.logger.info('have a request');
return next();
}
export default async function globalLog2(ctx: Context, next: Next) {
ctx.logger.info('have a request2');
return next();
}
// app/controller/FooController.ts
import { Middleware } from '@eggjs/tegg';
@Middleware(globalLog,globalLog2)
export class FooController {
@Middleware(methodCount)
async hello() {
}
}
当需要 egg context 时,可以使用 @Context
注解来声明。
// app/controller/FooController.ts
import { Context, EggContext } from '@eggjs/tegg';
export class FooController {
@Middleware(methodCount)
async hello(@Context() ctx: EggContext) {
}
}
@HTTPController
注解用来声明当前类是一个 HTTP controller,可以配置路径前缀。
@HTTPMethod
注解用来声明当前方法是一个 HTTP method,只有带了这个注解,HTTP 方法才会被暴露出去,可以配置方法路径,
// app/controller/FooController.ts
import { Context, EggContext, HTTPController, HTTPMethod, HTTPMethodEnum } from '@eggjs/tegg';
@HTTPController({
path: '/foo',
})
export class FooController {
@HTTPMethod({
method: HTTPMethodEnum.GET,
path: '/hello',
})
async hello() {
}
}
HTTP 协议中有各种各样的传参方式,比如 query,path,body 等等。
接收 body 参数
// app/controller/FooController.ts
import { Context, EggContext, HTTPController, HTTPMethod, HTTPMethodEnum, HTTPBody } from '@eggjs/tegg';
@HTTPController({
path: '/foo',
})
export class FooController {
@HTTPMethod({
method: HTTPMethodEnum.GET,
path: '/hello',
})
async hello(@HTTPBody() name: string) {
return `hello, ${name}`;
}
}
两者的区别在于参数是否为数组, HTTPQuery 只会取第一个参数,HTTPQueries 只提供数组形式。 HTTPQuery 的参数类型只能是 string, HTTPQueries 的参数类型只能是 string[]。
// app/controller/FooController.ts
import { Context, EggContext, HTTPController, HTTPMethod, HTTPMethodEnum, HTTPQuery, HTTPQueries } from '@eggjs/tegg';
@HTTPController({
path: '/foo',
})
export class FooController {
@HTTPMethod({
method: HTTPMethodEnum.GET,
path: '/hello',
})
async hello(
// /foo/hello?name=bar
// HTTPQuery: name=bar
// HTTPQueries: name=[bar]
@HTTPQuery() name: string,
@HTTPQueries() names: string[],
) {
return `hello, ${name}`;
}
}
如果需要使用别名,比如说 query 中的 name 不能在 js 中声明时,如 foo[bar] 这类的。可以通过以下形式
@HTTPQuery({ name: 'foo[bar]' }) fooBar: string,
接收 path 中的参数,类型只能为 string
// app/controller/FooController.ts
import { Context, EggContext, HTTPController, HTTPMethod, HTTPMethodEnum, HTTPBody } from '@eggjs/tegg';
@HTTPController({
path: '/foo',
})
export class FooController {
@HTTPMethod({
method: HTTPMethodEnum.GET,
path: '/:id',
})
async hello(@HTTPParam() id: string) {
return `hello, ${name}`;
}
}
如果需要使用别名,比如说 path 中使用正则声明 /foo/(.*)
, 可以通过以下形式
// 具体 name 值可以查看 path-to-regexp
@HTTPParam({ name: '0' }) id: string
Host 注解,用于指定 HTTP 方法仅在 host 匹配时执行。 可以添加在类/方法上。添加在类上时,对类上所有方法生效,添加在方法上时,只对当前方法生效。方法上的注解可以覆盖类上的注解
// app/controller/FooController.ts
import { Host } from '@eggjs/tegg';
@Host('foo.eggjs.com')
export class FooController {
// 仅能通过 foo.eggjs.com 访问
async hello() {
}
// 仅能通过 bar.eggjs.com 访问
@Host('bar.eggjs.com')
async bar() {
}
}
