我正在嘗試使用 Go 的反射庫(kù)，但遇到了一個(gè)我無(wú)法弄清楚的問(wèn)題：如何調(diào)用通過(guò)反射調(diào)用閉包函數(shù)返回的函數(shù)？是否有可能基本上有一個(gè)序列：func (f someType) closureFn(i int) int {  return func (x int) int {     return x+i  }}...fn := reflect.ValueOf(&f).MethodByName("closureFn")val := append([]reflect.Value{}, reflect.ValueOf(99))fn0 := fn.Call(val)[0]fn0p := (*func(int) int)(unsafe.Pointer(&f0))m := (*fn0p)(100)哪個(gè)應(yīng)該使 m 等于 199？以下是演示該問(wèn)題的簡(jiǎn)化代碼。對(duì)“虛擬”匿名函數(shù)的調(diào)用工作正常，對(duì)閉包的反射調(diào)用也是如此。然而，嘗試調(diào)用閉包返回失敗并返回 nil 指針（調(diào)試器中值地址上設(shè)置的標(biāo)志為 147，歸結(jié)為可尋址）。歡迎任何關(guān)于正在發(fā)生的事情的建議，或者如果可能的話。操場(chǎng)鏈接： https: //play.golang.org/p/0EPSCXKYOp0package mainimport (    "fmt"    "reflect"    "unsafe")// Typed Struct to hold the initialized jobs and group Filter function typestype GenericCollection struct {    jobs []*Generic}type Generic func (target int) intfunc main() {    jjf := &GenericCollection{jobs: []*Generic{}}    jjf.JobFactoryCl("Type", 20)}// Returns job function with closure on jobtypefunc (f GenericCollection) Job_by_Type_Cl(jobtype int) (func(int) int) {    fmt.Println("Job type is initialized to:", jobtype)    // Function to return    fc := func(target int) int {        fmt.Println("inside JobType function")            return target*jobtype    }    return fc}// Function factoryfunc (f GenericCollection) JobFactoryCl(name string, jobtype int) (jf func(int) int) {    fn := reflect.ValueOf(&f).MethodByName("Job_by_" + name + "_Cl")    val := append([]reflect.Value{}, reflect.ValueOf(jobtype))    if fn != reflect.ValueOf(nil) {        // Reflected function -- CALLING IT FAILS        f0 := fn.Call(val)[0]        f0p := unsafe.Pointer(&f0)        //Local dummy anonymous function - CALLING IS OK        f1 := func(i int) int {            fmt.Println("Dummy got", i)            return i+3        }
