现在将服务器值设置为时间戳 [英] Set server value now as timestamp

问题描述

我正在尝试使用firestore的其余api编写现在的时间戳.发送应用程序不会保留时间，因此要由服务器来存储值.

  {字段":{类型": {"stringValue":温度"}，时间戳记":{"timestampValue":"2019-02-18T23:00:00Z"}，价值": {"integerValue":"17"}}} 

这些值已正确存储，但我希望能够将静态2019-02-18T23:00:00Z更改为现在的值.

这怎么办?

解决方案

要在字段中写入服务器端时间戳，您需要使用 Firestore REST API添加时间戳和 https://cloud.google.com/firestore/docs/reference/rest/v1/写

I'm trying to write the now timestamp using the rest api of firestore. The sending application doesn't keep the time so its up to the server to store the value.

{
    "fields": {
        "Type": {
            "stringValue": "temperature"
            },
            "Timestamp": {
                "timestampValue": "2019-02-18T23:00:00Z"
            },
            "Value": {
                "integerValue": "17"
            }
    }
}

The values get stored properly but I want to be able to change the static 2019-02-18T23:00:00Z to the now value.

How can this be done?

解决方案

To write the server-side timestamp in a field, you need to use a FieldTransform for that. See Firestore REST API add Timestamp and https://cloud.google.com/firestore/docs/reference/rest/v1/Write
