云函数serverless环境下能支持hono

[zsnmwy]

需求

希望能够在云函数Serverless环境下，能够正常使用hono

如：
https://hono.dev/docs/getting-started/ali-function-compute

[binggg]

web 函数可以考虑支持这个

我写了一个库支持了一下，麻烦测试通过之后添加到文档以及开箱即用的案例中。

https://github.com/zsnmwy/hono-tencent-cloudbase-cloud-function-adapter

如果有问题，请给我提PR来fix

// 该示例全部能正常使用

'use strict';
const { Hono } = require("hono");
const { handle } = require("hono-tencent-cloudbase-cloud-function-adapter");

const app = new Hono();

app.get("/", (c) => c.text("Hello Hono!"));
app.get("/json", (c) => c.json({
    data: {
        a: 123
    },
    code: 200
}));
app.post("/", async (c) => c.json({
    requestBody: await c.req.json(),
    code: 200
}));

// 添加图片代理路由
app.get("/image", async (c) => {
    try {
        // 从查询参数获取图片URL
        const imageUrl = c.req.query("url");

        if (!imageUrl) {
            return c.json({ error: "Missing image URL parameter" }, 400);
        }

        // 获取远程图片
        const response = await fetch(imageUrl);

        if (!response.ok) {
            return c.json({ error: "Failed to fetch image", status: response.status }, 500);
        }

        // 获取图片内容类型
        const contentType = response.headers.get("content-type");
        // 获取图片数据
        const imageBuffer = await response.arrayBuffer();

        // 返回图片数据
        return c.body(imageBuffer, 200, {
            "Content-Type": contentType || "image/jpeg"
        });
    } catch (error) {
        console.error("Error fetching image:", error);
        return c.json({ error: "Failed to process image request" }, 500);
    }
});

// 添加文件上传处理路由
app.post("/upload", async (c) => {
    try {
        // 解析multipart/form-data请求体
        const body = await c.req.parseBody();

        // 获取上传的文件
        const file = body.file;

        // 检查文件是否存在
        if (!file) {
            return c.json({ error: "No file uploaded" }, 400);
        }

        // 处理文件信息
        let fileName;
        let fileSize;
        let fileType;

        if (typeof file === 'string') {
            // 如果是字符串，可能是文件路径或Base64编码
            fileName = "text-content";
            fileSize = file.length;
            fileType = "text/plain";
        } else {
            // 如果是File对象
            fileName = file.name;
            fileSize = file.size;
            fileType = file.type;
        }

        // 返回文件信息
        return c.json({
            success: true,
            fileName: fileName,
            fileSize: fileSize,
            fileType: fileType,
            code: 200
        });
    } catch (error) {
        console.error("Error processing file upload:", error);
        return c.json({
            error: "Failed to process file upload",
            message: error.message
        }, 500);
    }
});

// Handle timer trigger events
// Timer events are automatically converted to GET requests with path: /CLOUDBASE_TIMER_TRIGGER/${TriggerName}
app.get("/CLOUDBASE_TIMER_TRIGGER/:triggerName", (c) => {
  const triggerName = c.req.param("triggerName");

  // Access the original timer event from the environment
  const originalTimerEvent = c.env?.originalTimerEvent;

  console.log(`Timer triggered: ${triggerName}`);
  console.log(`Timer event:`, originalTimerEvent);

  // Perform your scheduled task here
  return c.json({
    message: `Timer ${triggerName} executed successfully`,
    timestamp: new Date().toISOString(),
    originalEvent: originalTimerEvent,
  });
});

exports.main = handle(app);

定时函数事件转换处理

[zsnmwy]

如果没啥问题的话，希望能够把我这段示例code放到开箱即用的模板里面。

• 常规的GET POST
• 图片返回处理
• 文件处理
• 定时事件处理

这些场景已经能够覆盖很多了。
