在使用 interface 表示任何类型时,如果要将 interface 转为某一类型,直接强制转换是不行的,例如: var t interface{} = "abc" s := string(t) cannot convert t(type interface {}) to type string: need type assertion 这样是不行的,需要进行 type assertion 类型断言,具体使用方法请参考:golang 任何类型...
variinterface{}="Hello"s:=i.(string) Go Copy 在上面的示例中,我们将一个接口类型i转换为字符串类型s。通过使用类型断言.(string),我们告诉编译器我们确信i保存了一个字符串值。 在进行类型断言之前,我们应该使用类型断言操作符.(type)检查接口的底层类型是否是我们期望的类型。如果底层类型不是我们期望的类型,...
问题原因:由于从Redis里 取出的数据为interface{}类型,需要先进行类型转换后,才能做后续处理 代码如下: res, err := redis.String(coon.Do("HGet", "users", id)) //这里如果不进行redis.String()操作,并且这里只能使用redis的函数 user = &User{} ...
fmt.Sprintf is a function within Go’s fmt package that returns a formatted string. It functions similarly to Printf, but instead of printing the output to the standard output, it returns the formatted string. Syntax: func Sprintf(format string, a ...interface{}) string Parameters: format ...
packagemainimport"fmt"funcprintString(valueinterface{}){str,ok:=value.(string)ifok{fmt.Println(str)}}funcmain(){printString("Hello, world!")} Go Copy 在这个例子中,我们定义了一个函数printString,它接受一个空接口类型的参数。在函数中,我们使用类型断言将传入的参数转换为 string 类型,并打印出来。
