我有这个变量可以从var RateLimiter = require('limiter').RateLimiter;
var createCsvWriter = require('csv-writer').createArrayCsvWriter;
var limiter = new RateLimiter(27, 'second', true);
const csvWriter = createCsvWriter({
header: ['NAME'],
path: './out.csv'
});
/** Mocked module - you can delete this */
const nexmo = {
numberInsight: {
get: (item, cb) => {
if (typeof cb !== 'function') {
cb = () => {}
}
let msg = {
status: 1,
status_message: `${item.number} - have passed`
};
cb(null, msg);
}
}
}
var final = ['john', 'mike', 'elise', 'valentine']
final = final.reduce((accumulator, item, index) => {
return accumulator.then(() => {
return new Promise(resolve => {
limiter.removeTokens(1, (err, remainingReq) => {
if (err) {
resolve(Promise.resolve(err.message));
} else {
nexmo.numberInsight.get({
level: 'basic',
number: item
}, (error, response) => {
if (error) {
resolve(Promise.resolve(error.message));
} else {
csvWriter.writeRecords([
[response.status_message]
]).then(() => {
resolve(response.status_message)
}).catch(writerErr => {
resolve(writerErr.message);
})
}
})
}
})
})
})
}, Promise.resolve());
final.then(lastPromiseResponse => {
console.log('final', lastPromiseResponse)
}).catch(err => {
console.log('final err', err);
})提取时间
DateTime.now();问题是，例如，如果时间是01:09:32，我得到的时间是1：9：32。
我如何获得常规格式的时间？
我可以使用if-else来做到这一点，但是我敢肯定有更好的方法

您可以尝试使用DateFormat，只需将pubspec.yaml包含intl依赖项
import 'package:intl/intl.dart';
DateTime now = DateTime.now();
String formattedTime = DateFormat.Hms().format(now);
print(formattedTime);
根据您的要求，您可以查看DateFormat
从DateFormat类获取的一些示例可以为您提供更多帮助。
String formattedTime = DateFormat.jm().format(now); //5:08 PM
String formattedTime = DateFormat.Hm().format(now); //17:08 force 24 hour time
