Dart client for the Consul KV-store.
Wraps Consul's simple key/value store API.
Client uses HTTP requests to communicate with Consul.
Each method has optional parameters that are described in Consul API docs.
You might want to wrap responses into some kind of handler
(check status codes, encode\convert values, etc.) - result is a flexible Response
object.
Each method return Future
which is used to get result.
Additional documentation can be found here.
A simple usage example:
Future main() async {
var consul = new ConsulKV(port: 5579, defaultHeaders: {'X-Consul-Token': 'bcd1234'});
var newKey = await consul.put('foo', 'bar');
var foundKey = await consul.get('foo');
var insertIfNotExists = await consul.put('foo', 'bar', cas: 1);
var deleteKey = await consul.delete('foo');
var keyNotExists = await consul.get('foo');
print(newKey.body); // true
print(newKey.statusCode); // 200
print(foundKey.body); // [{"LockIndex":0,"Key":"foo","Value":"YmFy",
// "CreateIndex":208877,"ModifyIndex":208877}]
print(foundKey.statusCode); // 200
print(insertIfNotExists.body); // false
print(insertIfNotExists.statusCode); // 200
print(deleteKey.body); // true
print(deleteKey.statusCode); // 200
print(keyNotExists.statusCode); // 404
consul.close();
}
