How to convert moment date to a string and remove the moment object
提问by Kelvin
I have a React Web App and a React Native Mobile App. When I pass a moment date object from my react web app to my backend, it gets converted to a string somehow and it works with my backend.
我有一个 React Web 应用程序和一个 React Native 移动应用程序。当我将一个时刻日期对象从我的 React Web 应用程序传递到我的后端时，它会以某种方式转换为一个字符串，并且它可以与我的后端一起使用。
When I do it with my react native mobile app, it passes the date as a moment object and it doesn't get converted to a string and it doesn't work.
当我使用我的本机移动应用程序执行此操作时，它将日期作为时刻对象传递，并且不会转换为字符串并且不起作用。
Is there a way to convert the moment object into a plain string like
有没有办法将时刻对象转换为普通字符串，如
"Tue May 05 2015 23:59:59 GMT+0800 (HKT)"
I tried toString() and toUTCString() and it doesn't work. Thanks.
我试过 toString() 和 toUTCString() 但它不起作用。谢谢。

Use moment().format()to create a formatted string from the date.
用于moment().format()从日期创建格式化字符串。
console.log(moment().format())<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.18.1/moment.js"></script>But if you're using version 2.1.0+ (link), toStringshould work:
但是，如果您使用的是 2.1.0+ 版（链接），则toString应该可以：
console.log(moment().toString())
console.log(typeof moment().toString())<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.18.1/moment.js"></script>回答by Soviut
You're trying to call methods that only exist on a javascript Dateobject. In order to call those methods you'd need to first convert the Momentobject into a plain Dateobject. You can use the .toDate()method on the Moment object to do this.
您正在尝试调用仅存在于 javascriptDate对象上的方法。为了调用这些方法，您需要首先将Moment对象转换为普通Date对象。您可以使用.toDate()Moment 对象上的方法来执行此操作。
var plainDate = moment().toDate();
console.log(plainDate.toUTCString());<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.18.1/moment.js"></script>However, a more direct way of converting a Moment object to a string is to use the .format()method, which will output as "ISO 8601" standard that looks like 2014-09-08T08:02:17-05:00.
但是，将 Moment 对象转换为字符串的更直接方法是使用.format()方法，该方法将输出为“ISO 8601”标准，类似于2014-09-08T08:02:17-05:00.
console.log( moment().format() );<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.18.1/moment.js"></script>
