go之如何在文件和结构中设置日期和日期数组

我必须在60s之后为每个请求保存一条记录，我必须将记录保存到我的appsettings.json中，例如

09/13/2019 11:38 AM: request count last 60s : 4 
09/13/2019 12:40 PM: request count last 60s : 6 

// Appsettings struct 
    Appsettings struct { 
        Requests []Requests `request` 
    } 
 
    // Requests struct 
    Requests struct { 
        RequestDate string      `requestDate` 
        Datas       []time.Time `datas` 
    } 

09/13/2019 11:38 AM: request count last 60s : 4 
09/13/2019 12:40 PM: request count last 60s : 6 

请您参考如下方法:

此示例代码:

package main 
 
import ( 
    "fmt" 
    "time" 
) 
 
type Requests struct { 
    RequestDate string      `requestDate` 
    Datas       []time.Time `datas` 
} 
 
type Appsettings struct { 
    Requests []Requests `request` 
} 
 
var appsettings Appsettings 
 
func addRequest(requestTime time.Time) { 
    timeString := requestTime.Format("01/02/2006 03:04 PM") 
 
    requestFound := false 
    for key, request := range appsettings.Requests { 
        if request.RequestDate == timeString { 
            requestFound = true 
            request.Datas = append(request.Datas, requestTime) 
            appsettings.Requests[key] = request 
        } 
    } 
 
    if requestFound == false { 
        newRequest := Requests{ 
            RequestDate: timeString, 
            Datas: make([]time.Time, 0), 
        } 
        newRequest.Datas = append(newRequest.Datas, requestTime) 
        appsettings.Requests = append(appsettings.Requests, newRequest) 
    } 
} 
 
func printRequests() { 
    for _, request := range appsettings.Requests { 
        fmt.Printf("%s: request count last 60s : %d\n", request.RequestDate, len(request.Datas)) 
    } 
} 
 
func main() { 
    appsettings = Appsettings{} 
    appsettings.Requests = make([]Requests, 0) 
 
    requestTime, _ := time.Parse(time.RFC3339, "2006-09-13T11:04:00Z") 
    addRequest(requestTime) 
 
    requestTime, _ = time.Parse(time.RFC3339, "2006-09-13T15:04:00Z") 
    addRequest(requestTime) 
 
    requestTime, _ = time.Parse(time.RFC3339, "2006-09-13T15:04:59Z") 
    addRequest(requestTime) 
 
    requestTime, _ = time.Parse(time.RFC3339, "2006-09-13T15:05:01Z") 
    addRequest(requestTime) 
 
    printRequests() 
} 

09/13/2006 11:04 AM: request count last 60s : 1 
09/13/2006 03:04 PM: request count last 60s : 2 
09/13/2006 03:05 PM: request count last 60s : 1
