示例1: storeHashtagsInTweets
storeHashtagsInTweets(jsons: Twitter.Status[]) {
const entries = [] as HashtagsScheme[];
const push = Array.prototype.push;
for (const j of jsons) {
if (!j.entities || !j.entities.hashtags) {
continue;
}
const hashtags = j.entities.hashtags
.map(h => ({
text: h.text,
timestamp: Date.now(),
}));
push.apply(entries, hashtags);
}
if (entries.length === 0) {
return Dexie.Promise.resolve<void>();
}
return this.table.bulkPut(entries)
.catch((e: Error) => {
log.error('Error on storing hashtags in tweets:', e, entries);
throw e;
});
