先上效果图

不局限在云湖，任何有收发消息API的即时通讯软件都可以部署

收消息

• 使用Cloudflare Worker部署
• 到电子邮件那里新建worker，再新建地址，选择转发到worker，选中刚刚创建的worker
• 因Cloudflare限制，必须使用wrangler开发（网页编辑器无法导入包）
• 使用wrangler创建项目，名字与刚创建的电子邮件worker相同
• 进入项目并安装postal-mime包
• 到云湖控制台中新建机器人

在 wrangler.toml 里写入如下变量

[vars]
YH_BOT_TOKEN = "换成你的云湖机器人Token"
YH_USER_ID = "换成你的ID"

然后编写代码：

import PostalMime from 'postal-mime';

async function toYunhu(msg, env) {
    const token = env.YH_BOT_TOKEN
    const apiUrl = 'https://chat-go.jwzhd.com/open-apis/v1/bot/send?token='+token
    const response = await fetch(apiUrl, {method: "POST",
        headers: {"Content-Type": "application/json; charset=utf-8"},
        body: JSON.stringify({
            recvId: env.YH_USER_ID,recvType: 'user',
            contentType: 'html',content: {text: msg}})})
    return response.json()
}

export default {
    async email(message, env, ctx) {
        let email_string = ``;
        const email_from = message.from;
        const email_to = message.to;
        email_string += `<ul><li>From: <code>${email_from}</code></li><li>To: <code>${email_to}</code></li>`;
        const email_content = await PostalMime.parse(message.raw);
        const email_subject = email_content.subject;
        let email_text = email_content.html;
        if (email_text == null) {
            email_text = email_content.text;
        }
        email_string += `<li>Title: <code>${email_subject}</code></li></ul><hr>${email_text}`;
        await toYunhu(email_string, env);
    },
};

最后使用wrangler部署

发消息（这一章节较为复杂！）

• 新建一个普通worker用于发送邮件
• 无需wrangler
• 准备 Github REST API Token（用于调用markdown转html接口）
• 准备 Resend Email Token（用于发送邮件）
• 将域名解析到Resend（可选）（如果想用域名邮箱则必须）

打开云湖控制台并新建自定义输入指令

把每个表单ID对应的输入框名记下来！

打开cloudflare网页编辑器并编写代码

async function sendEmail(email_to, email_title, email_content, env) {
    const token = env.RESEND_EMAIL_TOKEN
    const response = await fetch("https://api.resend.com/emails", {
        method: "POST",
        headers: {
            "content-type": "application/json",
            "Authorization": `Bearer ${token}`
        },
        body: JSON.stringify({
            from: "这里填入你的resend邮箱名，如果将域名解析到resend则可以填域名邮箱",
            to: email_to,
            subject: email_title,
            html: email_content
        })
    });
    return response.body;
}

async function toYunhu(msg, env) {
    const token = env.YH_BOT_TOKEN
    const apiUrl = 'https://chat-go.jwzhd.com/open-apis/v1/bot/send?token='+token
    const response = await fetch(apiUrl, {method: "POST",
        headers: {"Content-Type": "application/json; charset=utf-8"},
        body: JSON.stringify({
            recvId: env.YH_USER_ID,recvType: 'user',
            contentType: 'html',content: {text: msg}})})
    return response.json()
}

async function toHTML(markdown, env) {
    const token = env.GH_REST_TOKEN
    const response = await fetch("https://api.github.com/markdown", {
        method: "POST",
        headers: {
            'Accept': "application/vnd.github+json",
            'User-Agent': "Markdown-To-Html-App",
            'Authorization': `Bearer ${token}`,
            'X-GitHub-Api-Version': "2022-11-28"
        },
        body: JSON.stringify({text: markdown}),
    })
    return response.text();
}

async function getEmailInfo(yhJson) {
    let email_info = {}
    let formJson = yhJson['event']['message']['content']['formJson']
    if (formJson == null) {
        formJson = yhJson['event']['message']['content']['formjson']
    }
    email_info['address'] = formJson['这里是 目标 输入框的表单ID']['value']
    email_info['title'] = formJson['这里是 标题 输入框的表单ID']['value']
    email_info['content'] = formJson['这里是 正文 输入框的表单ID']['value']
    return email_info
}

export default {
    async fetch(request, env, ctx) {
        if (request.method == "POST") {
            const email_info = await getEmailInfo((await request.json()))
            const address = email_info['address']
            const title = email_info['title']
            const content = await toHTML(email_info['content'], env)
            const email_response = await sendEmail(address, title, content, env)
            await toYunhu("已发送", env)
            return new Response(email_response);
        }
    },
};

在 worker设置 -> 变量和机密 那里新建变量

• GH_REST_TOKEN：你的Github REST API Token
• RESEND_EMAIL_TOKEN：你的Resend Email Token
• YH_BOT_TOKEN：你的云湖机器人Token
• YH_USER_ID：你的云湖ID

部署完成
