### Notice
|
||
|
|
|
||
|
|
apollo config center use `Namespace` to be part of the key. For example:
|
||
|
|
|
||
|
|
***application.json***
|
||
|
|
|
||
|
|
```json
|
||
|
|
{
|
||
|
|
"http": {
|
||
|
|
"address": ":8080",
|
||
|
|
"tls": {
|
||
|
|
"enable": false,
|
||
|
|
"cert_file": "",
|
||
|
|
"key_file": ""
|
||
|
|
}
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
you got them in kratos config instance maybe look like:
|
||
|
|
|
||
|
|
```go
|
||
|
|
config := map[string]interface{}{
|
||
|
|
// application be part of the key path.
|
||
|
|
"application": map[string]interface{}{
|
||
|
|
"http": map[string]interface{}{
|
||
|
|
"address": ":8080",
|
||
|
|
"tls": map[string]interface{}{
|
||
|
|
"enable": false,
|
||
|
|
"cert_file": "",
|
||
|
|
"key_file": ""
|
||
|
|
}
|
||
|
|
}
|
||
|
|
}
|
||
|
|
}
|
||
|
