// 一条日志

        context.TODO(),clientOptions); err != nil {
        return
    }

    // 2, 选择数据库my_db
    database := client.Database("ichunt")

    // 3, 选择表my_collection
    collection := database.Collection("cron_log")
    // 4, 插入记录(bson)
    record := &LogRecord{
        JobName: "job10",
        Command: "echo hello",
        Err: "",
        Content: "hello",

    if result, err = collection.InsertOne(context.TODO(), record); err != nil {
        fmt.Println(err)
        return
    }

    fmt.Println(result)

    //// _id: 默认生成一个全局唯一ID, ObjectID：12字节的二进制
    docId := result.InsertedID.(primitive.ObjectID)
    fmt.Println("自增ID:", docId.Hex())
}

 

返回：

&{ObjectID("5e158ad09a14bfe14880829b")}
自增ID: 5e158ad09a14bfe14880829b
