How to create a push id for firebase using golang?
问题
我想将一个带有ID的地图推送到Firebase（例如：-KfKoScgRhylaLjQlK-y）。
fitToWorkMap := make(map[string]models.TaskFitToWork)
fitToWorkForTask := models.TaskFitToWork{}
for i := 0; i < len(FitToWorkSlice); i++ {
fitToWorkForTask.Info = FitToWorkSlice[i]
fitToWorkForTask.DateOfCreation = time.Now().Unix()
fitToWorkForTask.Status = helpers.StatusPending
fitToWorkMap["fgsgdsfn+'i'"] = fitToWorkForTask
}
task.FitToWork = fitToWorkMap
这里的fitToWorkMap是一个地图。我想为这个地图生成一个键。
英文:
i want to push a map to firebase with an id (eg:-KfKoScgRhylaLjQlK-y)
fitToWorkMap := make(map[string]models.TaskFitToWork)
fitToWorkForTask :=models.TaskFitToWork{}
for i := 0; i < len(FitToWorkSlice); i++ {
fitToWorkForTask.Info =FitToWorkSlice[i]
fitToWorkForTask.DateOfCreation =time.Now().Unix()
fitToWorkForTask.Status = helpers.StatusPending
fitToWorkMap["fgsgdsfn+'i'"] = fitToWorkForTask
}
task.FitToWork = fitToWorkMap
here fitToWorkMap is a map .i want to generate a key for this map

以-K开头的那些键被称为推送ID，它们是由Firebase自动生成的：
- 当你在支持的SDK中调用
push()或childByAutoId时 - 当你通过REST API执行
POST请求时
Go没有Firebase SDK，它使用REST API与Firebase数据库进行交互。这意味着它只在向数据库POST新节点时生成推送ID。我不知道有任何用于在Go中客户端生成Firebase推送ID的库。
但幸运的是，这些键在一篇博文中有很好的文档记录。还有一个JavaScript实现generatePushID()的代码可用，所以你可以将其移植到Go中。
英文:
Those keys starting with -K are called push IDs and they are automatically generated by Firebase:
- When you call
push()orchildByAutoIdin one of the supported SDKs - When you perform a
POSTrequest to the REST API
There is no Firebase SDK for Go and uses the REST API to interact with the Firebase Database. That means that it only generates a push ID when it POSTs a new node to the database. I don't know of any library for Go to generate Firebase push IDs client-side.
But luckily the keys are quite well documented in a blog post. The code for a JavaScript implementation of generatePushID() is also available, so you could port that over to Go.
