Question

我需要获得财产价值：

telegram_token：＆＃34; telegramtoken＆＃34;
other_token：＆＃34; othertoken＆＃34;

但是如果我Init() import api func main()并在package main import ( "fmt" "github.com/go-yaml/yaml" ) var ( cfg Config configData = []byte(`api: telegram_token: "telegramtoken" other_token: "othertoken"`) ) type Config struct { API ConfigAPI `yaml:"api"` } type ConfigAPI struct { TelegramToken string `yaml:"telegram_token"` OtherToken string `yaml:"other_token"` } func (c *Config) parse() { err := yaml.Unmarshal(configData, c) if err != nil { fmt.Println(err.Error()) } } func Init() { cfg.parse() fmt.Printf("%+v\n", cfg) } func main() { Init() }初始化功能，我就无法获得物业价值。为什么？谢谢！

这是有效的：

{API:{TelegramToken:telegramtoken OtherToken:othertoken}}

控制台： package api import ( "fmt" "github.com/go-yaml/yaml" ) var ( cfg Config configData = []byte(`api: telegram_token: "telegramtoken" waves_token: "wavestoken"`) ) type Config struct { API ConfigAPI `yaml:"api"` } type ConfigAPI struct { TelegramToken string `yaml:"telegram_token"` WavesToken string `yaml:"waves_token"` } func (c *Config) parse() { err := yaml.Unmarshal(configData, c) if err != nil { fmt.Println(err.Error()) } } func Init() { cfg.parse() fmt.Printf("%+v\n", cfg) }

不能工作：

package main

api.Init()，请参阅// The daemon that starts the API in background process. package main import ( "fmt" "log" "net/http" "time" "github.com/julienschmidt/httprouter" api "github.com/krypton-code/waves-bot/pkg/api" ) var ( host = "https://api.telegram.org/bot" method = "/getMe" ) // Index - home page. func Index(w http.ResponseWriter, r *http.Request, _ httprouter.Params) { fmt.Fprint(w, "<h1>Server of TelegaBot for Waves Platform is running!</h1>\n") } func main() { api.Init() router := httprouter.New() router.GET("/", Index) s := &http.Server{ Addr: ":8089", Handler: router, ReadTimeout: 10 * time.Second, WriteTimeout: 10 * time.Second, MaxHeaderBytes: 1 << 20, } log.Printf("\nApp listening on port%s. Go to http://localhost:8089/", s.Addr) log.Fatal(s.ListenAndServe()) }

{API:{TelegramToken: WavesToken:}}

通过缩进令牌字段来修改YAML以匹配预期的结构：

如果使用import func，如何在控制台中获取value属性？
