示例1: next
({ parseAscii, parseNative }: {
parseAscii: boolean;
parseNative: boolean;
}, next: NodeBack) => {
// initialise ascii flag
parse.setOptions({
ascii: parseAscii,
native: parseNative,
});
// always build on startup if in dev mode
if (nconf.any('build_emoji', 'BUILD_EMOJI')) {
next(null, true);
return;
}
// otherwise, build if never built before
access(tableFile, (err) => {
if (err && err.code !== 'ENOENT') {
next(err);
return;
}
next(null, !!err);
});
},示例2: cacheAndDeliver
const server = http.createServer((req: http.IncomingMessage, res: http.ServerResponse) => {
// Local variables
let lookup = path.basename(decodeURI(req.url)) || 'index.html';
let filePath = `${__dirname}/../content/${lookup}`
// fs.exists had deprecated. Please use fs.stat() or fs.access()
fs.access(filePath, (err: NodeJS.ErrnoException) => {
// Check file
console.log(err ? `${filePath} doesn't exist` : `${filePath} is there`);
// Response with 404
if (Boolean(err)) {
res.writeHead(404);
res.end('Page not Found!');
return;
}
// Read file when existed
cacheAndDeliver(filePath, (err: NodeJS.ErrnoException, data: Buffer) => {
// Content not found
if (err) { res.writeHead(500); res.end('ServerError!'); return; }
// Content can be found
let headers = { 'Content-type': mimeTypes[path.extname(lookup)] };
res.writeHead(200, headers);
res.end(data);
});
});
