[英]In NestJS, how do I uniformly convert a field whose data type is time type into a timestamp format and then return it to the front end?
Nestjs How can I convert date to Timestamp? Nestjs 如何将日期转换为时间戳? (I have tried many methods but it doesn't work, please help me) (我尝试了很多方法,但都不起作用,请帮助我)
This is the data type that I return now:这是我现在返回的数据类型:
{
"data": {
"results": [
{
"id": 1,
"create_time": "2021-02-27T03:04:06.240Z"
}
]
}
I hope to convert all dates into the following format我希望将所有日期转换为以下格式
{
"data": {
"results": [
{
"id": 1,
"create_time": "1614395046"
}
]
}
Although you can try to use the following methods to achieve, but I don't want to do this, I hope there is a more elegant solution虽然可以尝试使用下面的方法来实现,但是我不想这样做,希望有更优雅的解决方案
// Date.prototype.toJSON = (key) => {
// return moment(key).unix().toString()
// };
ps: ps:
Neither foreach nor gettime is what I want. foreach 和 gettime 都不是我想要的。 How do I handle this data type uniformly in Nest如何在 Nest 中统一处理这种数据类型
In native JavaScript you can use the Date
constructor to get an epoch in milliseconds.在本机 JavaScript 中,您可以使用Date
构造函数以毫秒为单位获取一个纪元。
new Date('2021-02-27T03:04:06.240Z').getTime();
given your JSON, simply manipulate it to change the date to a timestamp: and it looks like you have a number of elements in your JSON so:给定您的 JSON,只需对其进行操作即可将日期更改为时间戳:看起来您的 JSON 中有许多元素,所以:
var myDate = new Date();
for(var i=0;i<obj.data.results;i++){
obj.data.results[i].create_time = myDate(obj.data.results[i].create_time).getTime();
}
