如何在Go lang中读取config.json？

Question

I have used the following code in filLib.go:

func LoadConfiguration(filename string) (Configuration, error) {
    bytes, err := ioutil.ReadFile(filename)
    if err != nil {
        return Configuration{}, err
    }

    var c Configuration
    err = json.Unmarshal(bytes, &c)
    if err != nil {
        return Configuration{}, err
    }

    return c, nil
}

But ioutil.ReadFile(filename) return *os.PathError.

Both the files config.json and filLib.go are in same folder.

The issue might be with the filename you're providing. Below is the code sample that working fine for me.

func loadConfig() {
    var AppConfig Conf
    raw, err := ioutil.ReadFile("conf/conf.json")
    if err != nil {
       log.Println("Error occured while reading config")
       return
    }
    json.Unmarshal(raw, &AppConfig)
}
