server.ext({
type: `onPreHandler`,
method: (request, reply) => {
const defaultDir = '/public';
return getHostInfo(request.headers.host).then((d) => {
if (!d || !d.directory) {
request.app.dirPath = defaultDir;
return;
}
request.app.dirPath = d.directory;
}).catch((e) => {
request.app.dirPath = defaultDir;
}).then(() => {
return reply.continue();
});
}
});
然后是路线:
{
method: `get`,
path: `/l/{path*}`,
handler: {
directory: {
path: (request) => {
return request.app.dirPath;
}
}
}
}
