Question

我在Login Failed响应中有以下消息。响应以UTC格式显示日期。我想获取日期并从UTC转换为本地。我试过以下但我仍然有相同的日期格式。任何人都可以帮助我，我在这里做错了什么

var loginRes = 'Too many incorrect attempts. Account is locked until: 2018-03-16T05:13:58+00:00'


var dateRegx = /\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}-\d{2}:\d{2}/;
var ErrorMessage = (loginRes).replace(dateRegx, 
  function(match){
       return moment(match).format("MMMM Do YYYY, h:mm:ss a");
});
console.log(ErrorMessage);

在我的控制台打印件上，我和LoginRes一样。我期待的是：

Too many incorrect attempts. Account is locked until: March 16th 2018, 8:13:14 pm

Answer 1

您的正则表达式与日期

不匹配

var loginRes = 'Too many incorrect attempts. Account is locked until: 2018-03-16T05:13:58+00:00'


    var dateRegx = /(\d{4}-[01]\d-[0-3]\dT[0-2]\d:[0-5]\d:[0-5]\d\.\d+([+-][0-2]\d:[0-5]\d|Z))|(\d{4}-[01]\d-[0-3]\dT[0-2]\d:[0-5]\d:[0-5]\d([+-][0-2]\d:[0-5]\d|Z))|(\d{4}-[01]\d-[0-3]\dT[0-2]\d:[0-5]\d([+-][0-2]\d:[0-5]\d|Z))/;
    var ErrorMessage = (loginRes).replace(dateRegx, 
      function(match){
      console.log('tst')
           return moment(match).format("MMMM Do YYYY, h:mm:ss a");
    });
    console.log(ErrorMessage);

Answer 2

您也可以使用lastIndexOf()解决此问题：

var loginRes = 'Too many incorrect attempts. Account is locked until: 2018-03-16T05:13:58+00:00';
var idx = loginRes.lastIndexOf(' ');
var ErrorMessage = loginRes.substring(0, idx) + ' ' +
  moment(loginRes.substring(idx)).format("MMMM Do YYYY, h:mm:ss a");

console.log(ErrorMessage);

Answer 3

您的正则表达式不正确，与偏移前的+不匹配，您可以使用/\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}\+\d{2}:\d{2}/代替。

此外，您可以使用moment.utc将输入解析为UTC，并使用local()将其转换为本地模式。

var loginRes = 'Too many incorrect attempts. Account is locked until: 2018-03-16T05:13:58+00:00'

var dateRegx = /\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}\+\d{2}:\d{2}/;
var ErrorMessage = (loginRes).replace(dateRegx, 
  function(match){
       return moment.utc(match).local().format("MMMM Do YYYY, h:mm:ss a");
});
console.log(ErrorMessage);
