[英]Go cannot find file specified
I'm trying to make simple read settings from config file. 我正在尝试从配置文件中进行简单的读取设置。 Both files - config.json and Settings.go, are in the same folder.
config.json和Settings.go这两个文件都位于同一文件夹中。 But I'm always getting
"The system cannot find the file specified."
但是我总是收到
"The system cannot find the file specified."
What I'm doing wrong? 我做错了什么?
func GetDbConnectionString() string {
file, err := os.Open("config.json")
if err != nil {
log.Fatal(err)
}
decoder := json.NewDecoder(file)
settings := Settings{}
err1 := decoder.Decode(&settings)
if err1 != nil {
fmt.Println("error:", err1)
}
log.Print(&settings)
return fmt.Sprintf("%s:%s@/%s", settings.login, settings.password, settings.database)
}
Your settings.json
is not in the same directory as your main.go
. 您的
settings.json
与main.go
不在同一目录中。 If you invoke either go run main.go
, or go build . && ./app
如果您调用
go run main.go
或go build . && ./app
go build . && ./app
, the current path will be .../app/
which does not contain the settings.json
file. go build . && ./app
,当前路径将是.../app/
,其中不包含settings.json
文件。
Try copying your settings.json
file to the same directory as your app, local invocation will work (it will still fail if you run from a separate directory though). 尝试将您的
settings.json
文件复制到与您的应用相同的目录中,本地调用将起作用(但是,如果您从单独的目录运行,它将仍然失败)。
