Add admin get/set config keys API (#6113)
This PR adds two new admin APIs in Minio server and madmin package: - GetConfigKeys(keys []string) ([]byte, error) - SetConfigKeys(params map[string]string) (err error) A key is a path in Minio configuration file, (e.g. notify.webhook.1) The user will always send a string value when setting it in the config file, the API will know how to convert the value to the appropriate type. The user is also able to set a raw json. Before setting a new config, Minio will validate all fields and try to connect to notification targets if available.

|
||||
|
||||
SJSON is a Go package that provides a [very fast](#performance) and simple way to set a value in a json document. The purpose for this library is to provide efficient json updating for the [SummitDB](https://github.com/tidwall/summitdb) project.
|
||||
For quickly retrieving json values check out [GJSON](https://github.com/tidwall/gjson).
|
||||
|
||||
For a command line interface check out [JSONed](https://github.com/tidwall/jsoned).
|
||||
|
||||
Getting Started
|
||||
===============
|
||||
|
||||
Installing
|
||||
----------
|
||||
|
||||
To start using SJSON, install Go and run `go get`:
|
||||
|
||||
```sh
|
||||
$ go get -u github.com/tidwall/sjson
|
||||
```
|
||||
|
||||
This will retrieve the library.
|
||||
|
||||
Set a value
|
||||
-----------
|
||||
Set sets the value for the specified path.
|
||||
A path is in dot syntax, such as "name.last" or "age".
|
||||
This function expects that the json is well-formed and validated.
|
||||
Invalid json will not panic, but it may return back unexpected results.
|
||||
Invalid paths may return an error.
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import "github.com/tidwall/sjson"
|
||||
|
||||
const json = `{"name":{"first":"Janet","last":"Prichard"},"age":47}`
|
||||
|
||||
func main() {
|
||||
value, _ := sjson.Set(json, "name.last", "Anderson")
|
||||
println(value)
|
||||
}
|
||||
```
|
||||
|
||||
This will print:
|
||||
|
||||
```json
|
||||
{"name":{"first":"Janet","last":"Anderson"},"age":47}
|
||||
```
|
||||
|
||||
Path syntax
|
||||
-----------
|
||||
|
||||
A path is a series of keys separated by a dot.
|
||||
The dot and colon characters can be escaped with '\'.
|
||||
|
||||
```json
|
||||
{
|
||||
"name": {"first": "Tom", "last": "Anderson"},
|
||||
"age":37,
|
||||
"children": ["Sara","Alex","Jack"],
|
||||
"fav.movie": "Deer Hunter",
|
||||
"friends": [
|
||||
{"first": "James", "last": "Murphy"},
|
||||
{"first": "Roger", "last": "Craig"}
|
||||
]
|
||||
}
|
||||
```
|
||||
```
|
||||
"name.last" >> "Anderson"
|
||||
"age" >> 37
|
||||
"children.1" >> "Alex"
|
||||
"friends.1.last" >> "Craig"
|
||||
```
|
||||
|
||||
The `-1` key can be used to append a value to an existing array:
|
||||
|
||||
```
|
||||
"children.-1" >> appends a new value to the end of the children array
|
||||
```
|
||||
|
||||
Normally number keys are used to modify arrays, but it's possible to force a numeric object key by using the colon character:
|
||||
|
||||
```json
|
||||
{
|
||||
"users":{
|
||||
"2313":{"name":"Sara"},
|
||||
"7839":{"name":"Andy"}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
A colon path would look like:
|
||||
|
||||
```
|
||||
"users.:2313.name" >> "Sara"
|
||||
```
|
||||
|
||||
Supported types
|
||||
---------------
|
||||
|
||||
Pretty much any type is supported:
|
||||
|
||||
```go
|
||||
sjson.Set(`{"key":true}`, "key", nil)
|
||||
sjson.Set(`{"key":true}`, "key", false)
|
||||
sjson.Set(`{"key":true}`, "key", 1)
|
||||
sjson.Set(`{"key":true}`, "key", 10.5)
|
||||
sjson.Set(`{"key":true}`, "key", "hello")
|
||||
sjson.Set(`{"key":true}`, "key", map[string]interface{}{"hello":"world"})
|
||||
```
|
||||
|
||||
When a type is not recognized, SJSON will fallback to the `encoding/json` Marshaller.
|
||||
|
||||
|
||||
Examples
|
||||
--------
|
||||
|
||||
Set a value from empty document:
|
||||
```go
|
||||
value, _ := sjson.Set("", "name", "Tom")
|
||||
println(value)
|
||||
|
||||
// Output:
|
||||
// {"name":"Tom"}
|
||||
```
|
||||
|
||||
Set a nested value from empty document:
|
||||
```go
|
||||
value, _ := sjson.Set("", "name.last", "Anderson")
|
||||
println(value)
|
||||
|
||||
// Output:
|
||||
// {"name":{"last":"Anderson"}}
|
||||
```
|
||||
|
||||
Set a new value:
|
||||
```go
|
||||
value, _ := sjson.Set(`{"name":{"last":"Anderson"}}`, "name.first", "Sara")
|
||||
println(value)
|
||||
|
||||
// Output:
|
||||
// {"name":{"first":"Sara","last":"Anderson"}}
|
||||
```
|
||||
|
||||
Update an existing value:
|
||||
```go
|
||||
value, _ := sjson.Set(`{"name":{"last":"Anderson"}}`, "name.last", "Smith")
|
||||
println(value)
|
||||
|
||||
// Output:
|
||||
// {"name":{"last":"Smith"}}
|
||||
```
|
||||
|
||||
Set a new array value:
|
||||
```go
|
||||
value, _ := sjson.Set(`{"friends":["Andy","Carol"]}`, "friends.2", "Sara")
|
||||
println(value)
|
||||
|
||||
// Output:
|
||||
// {"friends":["Andy","Carol","Sara"]
|
||||
```
|
||||
|
||||
Append an array value by using the `-1` key in a path:
|
||||
```go
|
||||
value, _ := sjson.Set(`{"friends":["Andy","Carol"]}`, "friends.-1", "Sara")
|
||||
println(value)
|
||||
|
||||
// Output:
|
||||
// {"friends":["Andy","Carol","Sara"]
|
||||
```
|
||||
|
||||
Append an array value that is past the end:
|
||||
```go
|
||||
value, _ := sjson.Set(`{"friends":["Andy","Carol"]}`, "friends.4", "Sara")
|
||||
println(value)
|
||||
|
||||
// Output:
|
||||
// {"friends":["Andy","Carol",null,null,"Sara"]
|
||||
```
|
||||
|
||||
Delete a value:
|
||||
```go
|
||||
value, _ := sjson.Delete(`{"name":{"first":"Sara","last":"Anderson"}}`, "name.first")
|
||||
println(value)
|
||||
|
||||
// Output:
|
||||
// {"name":{"last":"Anderson"}}
|
||||
```
|
||||
|
||||
Delete an array value:
|
||||
```go
|
||||
value, _ := sjson.Delete(`{"friends":["Andy","Carol"]}`, "friends.1")
|
||||
println(value)
|
||||
|
||||
// Output:
|
||||
// {"friends":["Andy"]}
|
||||
```
|
||||
|
||||
Delete the last array value:
|
||||
```go
|
||||
value, _ := sjson.Delete(`{"friends":["Andy","Carol"]}`, "friends.-1")
|
||||
println(value)
|
||||
|
||||
// Output:
|
||||
// {"friends":["Andy"]}
|
||||
```
