我有一个结构，其字段形式为field[]interface{}。如果我打印该字段，我会得到一个指针引用。如果我尝试取消引用该字段，我会收到“无效间接”错误。代码如下:typeMyTypestruct{field[]interface{}}myType:=//createaMyType.Fieldisjustanarrayofnumbersprintln(myType.field)//printsapointerreference,ex:[1/1]0xc420269aa0println(*(myType.field))//doesn'tcompile如何打印myType.field中的值

而不是做:varadapters[]LogicAdapteradapter1:=&ExampleAdapter{0.9}adapter2:=&ExampleAdapter{0.8}adapters=append(adapters,adapter1,adapter2)bot:=ChatterBot{"Charlie",MultiLogicAdapter{adapters}}我试过:bot:=ChatterBot{"Charlie",MultiLogicAdapter{[]LogicAdapter{&ExampleAdapter{0.9},&ExampleAdapter{0.8}}}}但是

函数WithMutex和WithoutMutex给出了不同的结果。WithoutMutex实现正在丢失值，即使我设置了Waitgroup。有什么问题吗？DonotrunonPlayground附言我使用的是Windows10和Go1.8.1packagemainimport("fmt""sync")varp=fmt.PrintlntypeMuTypestruct{list[]int*sync.RWMutex}varmuData*MuTypevardata*NonMuTypetypeNonMuTypestruct{list[]int}func(data*MuType)add(iint,w

在链接的Playground示例中，我定义了一个类型:typeDoMapmap[int]func(Doer)stringDoer在我定义的接口(interface)类型中。我在具体类型MyDoer上实现接口(interface)。我希望能够构造一个DoMap，其中该映射中的条目包含如下两个函数:func(Doer)string//thisworksfunc(*MyDoer)string//thisdoesn'tfunc(MyDoer)string//more-or-lessthesameidea,alsodoesn't我不能，虽然很明显它们是不同的类型，但我想知道为什么我不能，因为函数

这个问题在这里已经有了答案:json.Marshal(struct)returns"{}"(3个答案)关闭5年前。我想知道为什么以下没有成功编码到json？我正在尝试使用一个非常简单的示例来学习json包。packagemainimport("encoding/json""fmt")typeMessagestruct{usernamestring`json:"name"`messagestring`json:"message"`}funcmain(){varm=Message{username:"hello",message:"world",}js,_:=json.Marshal(m)

我有以下代码：packagemainimport("sync""fmt")vardataSet=struct{sync.RWMutexdatamap[string]interface{}}{data:make(map[string]interface{})}funcmain(){dataSet.Lock()deferdataSet.Unlock()d:=dataSet.datatest:=[]string{"one","two","three"}m:=map[string]int{"one":1,"two":2,"three":3,}for_,t:=rangetest{d["data"

这是我要模拟的示例函数:packagemainimport"fmt"funcmain(){fmt.Println(fmt.Sprintf("InitiallyIwant%d%s",2,"dogs"))fmt.Println(Sprintf2("NowIwant%d%s",2,"dogs"))}funcSprintf2(formatstring,a...interface{})string{returnfmt.Sprintf(format+"and%dcats",append(a,5))}这是playground中的一个链接:https://play.golang.org/p/dHDwT
