示例1: Promise
return new Promise((resolve: (value: Repo) => void, reject: (error: any) => void) => {
this.alreadyTryFetchAll = true;
// check network connectivity
let hostname: string;
if (this.urlInfo) {
hostname = this.urlInfo.hostname;
} else if (this.sshInfo) {
hostname = this.sshInfo.hostname;
} else {
throw new Error("unsupported url: " + this.spec.url);
}
dns.resolve(hostname, err => {
this.networkConnectivity = !err;
if (this.networkConnectivity) {
let command: { base: string; args: string[]; };
if (fs.existsSync(this.targetDir)) {
command = this._buildCommand("fetch", "--all");
} else {
debug("make dir", path.resolve(this.targetDir, "../"));
mkdirp.sync(path.resolve(this.targetDir, "../"));
command = this._buildCommand("clone", "--mirror", this.spec.url, this.targetDir);
}
debug("exec command", command);
child_process.execFile(command.base, command.args, { encoding: "buffer" }, (error, stdout, stderr) => {
this.fetchError = error ? stderr.toString("utf8") : null;
resolve(this);
});
} else {
if (!fs.existsSync(this.targetDir)) {
reject("no network connectivity");
return;
} else {
resolve(this);
return;
}
}
});
});示例2: trueOrFalse
dns.lookup("nodejs.org", {all: true}, (err, addresses) => {
const _err: NodeJS.ErrnoException = err;
const _address: dns.LookupAddress[] = addresses;
});
function trueOrFalse(): boolean {
return Math.random() > 0.5 ? true : false;
}
