我有以下示例GO代码,它将来自REST请求(GIN)的数据插入到MongoDB中,但它失败了,出现以下错误:
['timestamp' must be present and contain a valid BSON UTC datetime value]
代码:
func CreateDevicesReadings(c *gin.Context) {
var devicesReadings DevicesReadings
c.BindJSON(&devicesReadings)
// Connect to MongoDB
client, err := mongo.Connect(context.Background(), clientOptions)
if err != nil {
c.JSON(500, gin.H{
"message": "Internal Server Error. Could not connect to the database.",
})
log.Default().Println(err)
}
collection := client.Database("florly").Collection("devicesReadings")
ctx, _ := context.WithTimeout(context.Background(), 5*time.Second)
// Set timestamp to the current time at the moment of the request
for i := 0; i < len(devicesReadings.DevicesReadings); i++ {
devicesReadings.DevicesReadings[i].Timestamp = time.Now().UTC()
}
_, err = collection.InsertOne(ctx, devicesReadings)
if err != nil {
c.JSON(500, gin.H{
"message": "Internal Server Error. Could not insert the data into the database.",
})
log.Default().Println(err)
} else {
log.Default().Println("Data inserted successfully.")
}
client.Disconnect(context.Background())
}
type DeviceReadings struct {
ID primitive.ObjectID `json:"_id,omitempty" bson:"_id,omitempty"`
Alias string `json:"alias" bson:"alias"`
Timestamp time.Time `json:"timestamp,omitempty" bson:"timestamp"`
SystemReadings SystemReadings `json:"systemReadings" bson:"systemReadings"`
SensorReadings SensorReadings `json:"sensorsReadings" bson:"sensorsReadings"`
}
我做错了什么?我认为MongoDB完成了将类型time.time
转换为MongoDB查找的类型的整个过程.
