我正在用Go解析一个大型JSON文件，我只需要从JSON中提取特定的项目。它通常是一个非常大的文件，但最终，它变成了这样:"textAnnotations":[{"boundingPoly":{"vertices":[{"x":136,"y":119},{"x":5606,"y":119},{"x":5606,"y":3985},{"x":136,"y":3985}]},"description":"Description","locale":"en"},{"boundingPoly":{"vertices":[{"x":3420,"y":122},{"x":3439,"y":122}

我可以成功地从客户端向服务器发送消息。但是当我尝试回复消息给客户端时，客户端却无法接收到消息。客户:conn,_:=net.Dial("udp",serv_addr:port)deferconn.close()buf:=[]byte("Hey,server")conn.Write(buf)recv:=make([]byte,1024)fmt.Println("Reading...\n")conn.Read(recv)服务器:addr,_:=net.ResolveUDPAddr("udp",addr:port)msg:=make([]byte,1024)conn,_:net.Listen

我正在尝试更好地编写调用远程api的模拟golang测试我可以使用httptest库很容易地模拟单个调用，但我是在处理多次调用单个端点调用的其他函数时卡住了。例如给定一个简单的创建函数funccreateItem(urlstring,productProduct)(int,error){//makerequestreturncreatedId,nil}我可以写一些像这样的测试funcTestCreateItem(t*testing.T){mock_ts:=httptest.NewServer(http.HandlerFunc(func(whttp.ResponseWriter,r*ht

简单的golang应用给出以下错误.\test.go:13:cannotuseds(typeData_A)astype[]interface{}infieldvalue下面的代码packagemaintypeData_Astruct{astring}typeDTResponsestruct{Data[]interface{}`json:"data"`}funcmain(){ds:=Data_A{"1"}dtResp:=&DTResponse{Data:ds}print(dtResp)}我想要一个带有任何类型slice变量的结构。使用struct{}会产生同样的错误。在Java中，我可以

func(priv*PrivateKey)Decrypt(randio.Reader,ciphertext[]byte,optscrypto.DecrypterOpts)(plaintext[]byte,errerror)以上是golangcrypto/rsa库中的函数。我不太明白这里对参数opts的解释。Decryptdecryptsciphertextwithpriv.Ifoptsisniloroftype*PKCS1v15DecryptOptionsthenPKCS#1v1.5decryptionisperformed.Otherwiseoptsmusthavetype*OAEP

我正在阅读这个页面(我没有使用亚马逊，只是为了golang教育而阅读)https://aws.amazon.com/blogs/developer/mocking-out-then-aws-sdk-for-go-for-unit-testing/当我自己尝试时，我遇到了类型错误。typeQueuestruct{ClientThirdPartyStructURLstring}typemockedReceiveMsgsstruct{ThirdPartyStructRespValueIWantToMock}q:=Queue{Client:mockedReceiveMsgs{}}当我尝试做完全

我在使用goexec包时遇到问题。我收到这个错误:'\"C:\ProgramFiles\SublimeText3\sublime_text.exe\"'isnotrecognizedasaninternalorexternalcommand,operableprogramorbatchfile.当我尝试在Windows机器上用golang运行这段代码时:packagemainimport("os/exec""fmt")funcmain(){varCMDstring="\"C:\\ProgramFiles\\SublimeText3\\sublime_text.exe\"C:\\User

有一个数组对象，它是从mongodb中检索到的。数据如下所示:-[{1fruitsAppleAppleismyfavoritefruit.}{2colorsRedRedcolorisalwayscharming.}{3flowersLotusItisoneofthemostbeautifulflowersinthisworld.}]这是获取上述数据的代码结构是:typeItemstruct{Idint`json:"id"`Categorystring`json:"category"`Namestring`json:"name"`Descriptionstring`json:"descr

我有下面的代码teasers:=[]*models.TeaserCount{}varteasermodels.TeaserCountfor_,product:=rangeProductResponse.Products{added:=falseiflen(product.Campaign.Id)>0{iflen(teasers)>0{for_,teaserCount:=rangeteasers{ifteaserCount.Id==product.Campaign.Id{fmt.Println(teaserCount.Id,teaserCount.Count+1)teaserCount.

我想保护我的API，以便授权用户可以访问我的API。这里的路由器如下:-Router.go//herethecustomerwillregister.Route{"SaveUser","POST","/signup",controller.SaveUser},//herethecustomerwillloginwithitsusernameandpassword.Route{"LoginUser","POST","/login",controller.Login},//APIsthatavalidusercanaccessRoute{"SaveCustomers","POST","/c
