type PersonInterfaceinterface{ GetName()stringGetAge()int} AI代码助手复制代码 实现一个函数,将接口类型转换为结构体类型。例如: funcConvertInterfaceToStruct(p PersonInterface)(Person,error) { jsonStr, err := json.Marshal(p)iferr !=nil{returnPerson{}, err }varperson Person err = json.Unmarshal(...
t.Logf("y type=%T val=%#v", y, y)varfint=10varh *int= &fvaro *int64//int和int64指针直接转换编译器报错因为有可能溢出改用unsafe//cannot convert p (type *int) to type *int64//o = (*int64)(h)o = (*int64)(unsafe.Pointer(h)) ...
// convertAssign copies to dest the value in src, converting it if possible. // An error is returned if the copy would result in loss of information. // dest should be a pointer type. funcconvertAssign(dest, srcinterface{}) error { ...

还是以上面例子举例,goverter包通过interface定义的方式,先让你预定义这个结构体,然后会生成转换函数。...
var i interface{}i 就是一个空接口类型,我们知道可以把任意类型的值,赋给一个空接口类型。 我们在源码中找到空接口数据结构的定义: typeefacestruct{_type*_type// 动态类型dataunsafe.Pointer// 原数据地址} 咱们注意一下_type类型, 它代表了Golang 所有的数据类型的元数据。所有数据类型都是在它的基础上,...
package main import ( "fmt" ) // 定义一个结构体来表示对象 type Person struct { Name string Age int } // 定义一个接口,并说明该接口需要实现的方法 type Describer interface { Describe() string } // 为Person类型实现Describer接口 func (p *Person) Describe() string { return fmt.Sprintf("Nam...
