paladin
项目简介
paladin 是一个config SDK客户端,包括了file、mock几个抽象功能,方便使用本地文件或者sven\apollo配置中心,并且集成了对象自动reload功能。
local files:
demo -conf=/data/conf/app/msm-servie.toml
// or dir
demo -conf=/data/conf/app/
注:使用远程配置中心的用户在执行应用,如这里的demo
时务必不要带上-conf
参数,具体见下文远程配置中心的例子
local file example:
type exampleConf struct {
Bool bool
Int int64
Float float64
String string
}
func (e *exampleConf) Set(text string) error {
var ec exampleConf
if err := toml.Unmarshal([]byte(text), &ec); err != nil {
return err
}
*e = ec
return nil
}
func ExampleClient() {
if err := paladin.Init(); err != nil {
panic(err)
}
var (
ec exampleConf
eo exampleConf
m paladin.TOML
strs []string
)
// config unmarshal
if err := paladin.Get("example.toml").UnmarshalTOML(&ec); err != nil {
panic(err)
}
// config setter
if err := paladin.Watch("example.toml", &ec); err != nil {
panic(err)
}
// paladin map
if err := paladin.Watch("example.toml", &m); err != nil {
panic(err)
}
s, err := m.Value("key").String()
b, err := m.Value("key").Bool()
i, err := m.Value("key").Int64()
f, err := m.Value("key").Float64()
// value slice
err = m.Value("strings").Slice(&strs)
// watch key
for event := range paladin.WatchEvent(context.TODO(), "key") {
fmt.Println(event)
}
}
remote config center example:
type exampleConf struct {
Bool bool
Int int64
Float float64
String string
}
func (e *exampleConf) Set(text string) error {
var ec exampleConf
if err := yaml.Unmarshal([]byte(text), &ec); err != nil {
return err
}
*e = ec
return nil
}
func ExampleApolloClient() {
/*
pass flags or set envs that apollo needs, for example:
```
export APOLLO_APP_ID=SampleApp
export APOLLO_CLUSTER=default
export APOLLO_CACHE_DIR=/tmp
export APOLLO_META_ADDR=localhost:8080
export APOLLO_NAMESPACES=example.yml
```
*/
if err := paladin.Init(apollo.PaladinDriverApollo); err != nil {
panic(err)
}
var (
ec exampleConf
eo exampleConf
m paladin.Map
strs []string
)
// config unmarshal
if err := paladin.Get("example.yml").UnmarshalYAML(&ec); err != nil {
panic(err)
}
// config setter
if err := paladin.Watch("example.yml", &ec); err != nil {
panic(err)
}
// paladin map
if err := paladin.Watch("example.yml", &m); err != nil {
panic(err)
}
s, err := m.Value("key").String()
b, err := m.Value("key").Bool()
i, err := m.Value("key").Int64()
f, err := m.Value("key").Float64()
// value slice
err = m.Value("strings").Slice(&strs)
// watch key
for event := range paladin.WatchEvent(context.TODO(), "key") {
fmt.Println(event)
}
}
编译环境
- 请只用 Golang v1.12.x 以上版本编译执行
