在向 Cobra 控制臺(tái)應(yīng)用程序添加第二個(gè)子命令后，我收到了錯(cuò)誤(no value) used as value。查找錯(cuò)誤，它說(shuō)發(fā)生了 TooManyValues。好像我試圖返回 2 個(gè)值而不是 1 個(gè)。這很簡(jiǎn)單，但我不確定這如何適用于我編寫的代碼。我不應(yīng)該將函數(shù)添加到與 cobra 控制臺(tái)代碼相同的文件中嗎？錯(cuò)誤：go build -o azGoCLI.exe# azGoCLI/cmdcmd\blob.go:40:25: DeleteContainer(args[0], args[1]) used as value非常感謝提前！package cmdimport ( "context" "log" "github.com/Azure/azure-sdk-for-go/sdk/azidentity" "github.com/Azure/azure-sdk-for-go/sdk/storage/azblob" "github.com/spf13/cobra")func init() { rootCmd.AddCommand(mainCmd) mainCmd.AddCommand(createContainer) mainCmd.AddCommand(deleteContainer)}var mainCmd = &cobra.Command{ Use: "blob", Short: "...", Run: func(cmd *cobra.Command, args []string) { cmd.Usage() },}var createContainer = &cobra.Command{ Use: "create-container [storageAccount] [containerName]", Short: "...", Args: cobra.MinimumNArgs(2), RunE: func(cmd *cobra.Command, args []string) error { return CreateContainer(args[0], args[1]) },}var deleteContainer = &cobra.Command{ Use: "delete-container [storageAccount] [containerName]", Short: "...", Args: cobra.MinimumNArgs(2), RunE: func(cmd *cobra.Command, args []string) error { return DeleteContainer(args[0], args[1]) },}func CreateContainer(storageaccount, container string) error { cred, err := azidentity.NewDefaultAzureCredential(nil) if err != nil { log.Fatalf("Authentication failure: %+v", err) } ctx := context.Background() containerClient, err := azblob.NewContainerClient("https://"+storageaccount+".blob.core.windows.net/"+container, cred, nil) _, err = containerClient.Create(ctx, nil) if err != nil { log.Fatal(err) } return nil}func DeleteContainer(storageaccount, container string) { cred, err := azidentity.NewDefaultAzureCredential(nil) if err != nil { log.Fatalf("Authentication failure: %+v", err) }

如您所見，您的功能
func DeleteContainer(storageaccount, container string) {
不返回任何東西。但是你在這里返回它：
var deleteContainer = &cobra.Command{
Use: "delete-container [storageAccount] [containerName]",
Short: "...",
Args: cobra.MinimumNArgs(2),
RunE: func(cmd *cobra.Command, args []string) error {
return DeleteContainer(args[0], args[1])
},
}
RunE好像它返回了一個(gè)error. 這就是它拋出錯(cuò)誤的原因。
解決這個(gè)問題將取決于您的用例，但如果出現(xiàn)錯(cuò)誤，您希望如何處理DeleteContainer錯(cuò)誤

解決方案：為DeleteContainer函數(shù)添加一個(gè)返回值和一個(gè)return語(yǔ)句。
func DeleteContainer(storageaccount, container string) error {
cred, err := azidentity.NewDefaultAzureCredential(nil)
if err != nil {
log.Fatalf("Authentication failure: %+v", err)
}
ctx := context.Background()
containerClient, err := azblob.NewContainerClient("https://"+storageaccount+".blob.core.windows.net/"+container, cred, nil)
_, err = containerClient.Delete(ctx, nil)
if err != nil {
log.Fatalf("Failure: %+v", err)
}
return nil
}
