API 网关（HTTP）

API 网关在腾讯云函数体系中类似于 HTTP 函数，我们通过它将函数发布为 HTTP 服务。

使用方式

import { Provide, Inject, ServerlessTrigger, ServerlessTriggerType } from '@midwayjs/decorator';import { Context } from '@midwayjs/faas';
@Provide()export class HelloTencentService {  @Inject()  ctx: Context;
  @ServerlessTrigger(ServerlessTriggerType.API_GATEWAY, {    path: '/api_gateway_tencent',    method: 'post',  })  async handleAPIGatewayEvent(@Body() name) {    return `hello ${name}`;  }}

在 npm run deploy 后即可通过控制台输出的链接访问。

本地测试

和传统应用 HTTP 测试相同，通过 createFunctionApp 创建函数 app，通过 createHttpRequest 方式进行测试。

import { Framework } from '@midwayjs/serverless-app';import { createFunctionApp, createHttpRequest } from '@midwayjs/mock';
describe('test/hello_tencent.test.ts', () => {  let app: Application;  let instance: HelloTencentService;
  beforeAll(async () => {    // create app    app = await createFunctionApp<Framework>();  });
  afterAll(async () => {    await close(app);  });
  it('should get result from http trigger', async () => {    const result = await createHttpRequest(app).post('api_gateway_tencent').send({      name: 'zhangting',    });
    expect(result.text).toEqual('hello zhangting');  });});
