Multiple-value strconv.Atoi() (int, error) in single-value context 1. 这是因为返回的数据有两个参数,代码里只定义了一个,所以代码里需要再加上一个参数,这个参数一般会定义为 err devicePositionType,err := strconv.Atoi(info[0]["device_position_type"].(string)) 1. 但是err后面我又用不到,如果...
3.函数有多个返回值时,multiple-value strconv.Atoi() in single-value context ,不需要的参数要用_接收4.Lissajour服务里面的cycles参数要是float64类型,使用cycles,_ := strconv.ParseFloat(v[0],64)函数转换5.不能有任何输出语句,否则会弹出下载框6.传参不能太大,要进行一下判断,否则CPU占满 效果图: ...

参考What does “hot path” mean in the context of sync.Once? - StackOverflow 3.3 性能差异 我们以一个简单示例,来说明使用 sync.Once 保证函数只会被执行一次和多次执行,二者的性能差异。 考虑一个简单的场景,函数 ReadConfig 需要读取环境变量,并转换为对应的配置。环境变量在程序执行前已经确定,执行过程中...
This function is a closure so it uses its incoming context register. 局部变量声明 局部变量存储在函数栈上,因此不需要额外进行声明,在函数栈上预留出空间,使用命令操作这些内存即可。因此这些 局部变量没有标识,操作时,牢记局部变量的分布、内存偏移即可。 宏 在汇编文件中可以定义、引用宏。通过#define get_...
