# Reading Json Configuration by Golang

As we all know, go language gives us a simple library to read json file. However, when it comes to more complex json file it

is weak,so we want to give you a stronger and more robust way to get json value.

# How to use it

[中文版本](./README_ZH.md)

- Use command below to install package `gojsonconfig`

```

go mod -u "https://github.com/xieyuschen/json-to-go-types"

```

- You can use command `gojsonconfig -v` to check whether you install this package successfully or not. If you are successful,

you will see output as this at terminal.

```sh

$ json-to-go-types -v

v0.1

```

- Generate a struct based on json file for further reading

Firstly your current path needs to contain a json file named `config.json`. Secondly your current path needs to have a folder

called `models` where the generated struct model will be stored.

If your path has no folder named `models`,please create one first.Your path dictionary would like this:

```

$-->your current postion

|__config,json

|__models(This is a folder)

```

Do command below after all of thing before done.

 ```

json-to-go-types -g

```

After this you can find a `Config_gen.go` file in `models` dictionary which is a struct based on the `config.json`.

- You can read json to the model generated before like this:

```go

func main(){

	conf:=ReadSettingsFromFile("config.json")

	fmt.Println(config.DbSettings.Password)

}

func ReadSettingsFromFile(settingFilePath string)(config models.Config){

	jsonFile, err := os.Open(settingFilePath)

	if err != nil {

		fmt.Println(err)

	}

	defer jsonFile.Close()

	byteValue, _ := ioutil.ReadAll(jsonFile)

	err = json.Unmarshal(byteValue, &config)

	if err != nil {

		log.Panic(err)

	}

	return config

}

```
