如何在Hapijs中获取原始请求体的缓冲区？

const Hapi = require('hapi');

const server = Hapi.server({
    port: 3000,
    host: 'localhost'
});

server.route({
    method: 'POST',
    path: '/example',
    handler: (request, h) => {
        const rawData = [];
        request.raw.req.on('readable', () => {
            let chunk;
            while ((chunk = request.raw.req.read()) !== null) {
                rawData.push(chunk);
            }
        });
        request.raw.req.on('end', () => {
            const buffer = Buffer.concat(rawData);
            // 在这里可以使用buffer进行后续处理
            console.log(buffer.toString());
        });

        return 'Request received';
    }
});

const start = async () => {
    try {
        await server.start();
        console.log('Server running at:', server.info.uri);
    } catch (err) {
        console.log(err);
        process.exit(1);
    }
};

start();
