通过其他 worker 增强
临时邮箱的核心能力在邮件的管理,通过其他 worker 可以增强临时邮箱的功能,例如通过 auth-inbox ai 能力解析验证码或激活链接
该功能仅触发其他 worker ,在 webhook 后执行
[!NOTE]
如果要使用 worker 增强,请提前创建可以 rpc 调用的 worker,具体下文详述
参考:
创建其他 worker(以 auth-inbox 项目ai解析验证码为例子)
worker 改造为继承 WorkerEntrypoint
一个简单,作为被调用方,提供 rpc 方法调用的worker代码如下(rpcEmail 方法为样例) (使用已经修改好的项目 https://github.com/oneisall8955/AuthInbox-fork)
src/index.ts 文件
js
import { WorkerEntrypoint } from "cloudflare:workers";
interface Env {
DB: D1Database;
// ...
}
export default class extends WorkerEntrypoint<Env> {
async fetch(request: Request): Promise<Response> {
console.log("原本fetch接口入参是request,env,ctx");
console.log("修改为WorkerEntrypoint风格后,只有一个入参request,获取环境变量和上下文有小改动");
// 环境变量及上下文改动详见:
// https://developers.cloudflare.com/workers/runtime-apis/bindings/service-bindings/rpc/#bindings-env
// https://developers.cloudflare.com/workers/runtime-apis/bindings/service-bindings/rpc/#lifecycle-methods-ctx
const env: Env = this.env;
const ctx: ExecutionContext = this.ctx;
console.log("后续逻辑不变");
return new Response('ok', { status: 200 });
}
// 主要功能
async email(message: ForwardableEmailMessage): Promise<void> {
console.log("原本fetch接口入参是message,env,ctx");
console.log("修改为WorkerEntrypoint风格后,只有一个入参message,获取环境变量和上下文和fetch方法一样");
const env: Env = this.env;
const ctx: ExecutionContext = this.ctx;
console.log("接受email routing请求后,后续逻辑不变");
}
// 暴露rpc接口,处理来自其他worker的邮件请求
async rpcEmail(requestBody: string): Promise<void> {
console.log(`接受其他worker(临时邮件服务cloudflare_temp_email)的请求,request body: ${requestBody}`);
// requestBody json 格式,由临时邮件服务发送,格式如下
// type RPCEmailMessage = {
// from: string | undefined | null,
// to: string | undefined | null,
// rawEmail: string | undefined | null,
// headers: Map<string, string>,
// }
// ... todo ...
}
}
部署其他 worker
修改好或者使用 以auth-inbox 为例,部署到 cloudflare worker 上,详见 https://github.com/TooonyChen/AuthInbox ,或者使用已经修改好的项目 https://github.com/oneisall8955/AuthInbox-fork
配置临时邮件服务,使用指定其他 worker 增强
绑定服务
通过 wrangler.toml 配置
toml
[[services]]
binding = "AUTH_INBOX"
service = "auth-inbox"
这里的 binding = "AUTH_INBOX"
可以自定义,可以是任何字符串,service = "auth-inbox"
是部署好的提供rpc接口调用的worker名称。
用户界面配置
在设置-绑定,添加绑定,选择绑定服务。
变量名称填写自定义的名称,可以任意字符串 ,例如 AUTH_INBOX
。
服务绑定选择上一步创建好的服务,例如 auth-inbox
。
环境变量配置
通过 wrangler.toml 配置
toml
ENABLE_ANOTHER_WORKER = true
ANOTHER_WORKER_LIST ="""
[
{
"binding":"AUTH_INBOX",
"method":"rpcEmail",
"keywords":[
"验证码","激活码","激活链接","确认链接","验证邮箱","确认邮件","账号激活","邮件验证","账户确认","安全码","认证码","安全验证","登陆码","确认码","启用账户","激活账户","账号验证","注册确认",
"account","activation","verify","verification","activate","confirmation","email","code","validate","registration","login","code","expire","confirm"
]
}
]
"""
环境变量解释:
- ENABLE_ANOTHER_WORKER = true:默认为false,true则开启其他 worker 处理邮件
- ANOTHER_WORKER_LIST 是一个JOSN数组,每个对象包3个字段
- binding: 必填,必须与services部分指定的 binding = "XXX" 保持一致,例子中为 AUTH_INBOX
- method: 可选,默认 rpcEmail,指的是调用这个 worker 的哪一个 rpc 方法处理
- keywords: 关键词数组,忽略大小写。用于过滤,如果解析后邮件文本匹配到这些关键词,触发这个 worker,并且调用这个 worker 的
method
方法
用户界面配置
在设置-环境变量,添加环境变量
- ENABLE_ANOTHER_WORKER = true
- ANOTHER_WORKER_LIST 为上面提及的JSON数组字符串,不再复述,详细介绍看上文
json
[
{
"binding":"AUTH_INBOX",
"method":"rpcEmail",
"keywords":[
"验证码","激活码","激活链接","确认链接","验证邮箱","确认邮件","账号激活","邮件验证","账户确认","安全码","认证码","安全验证","登陆码","确认码","启用账户","激活账户","账号验证","注册确认",
"account","activation","verify","verification","activate","confirmation","email","code","validate","registration","login","code","expire","confirm"
]
}
]
测试
发送一个邮件到临时邮箱,观察worker日志到,或者到 auth-inbox 提供的面板上查看验证码
