JobSchedulerのREST-APIを使ってみる - JavaのRestClient実装 -

##1.JobSchedulerのREST-API向けのClient本体のソースです。

/tmp/kaeru/RestClient.java というソースファイル名で保存します。

詳細手順はこちらの記事をご確認ください。

Client本体を実際使用する場合のサンプルコードはこちらをご確認ください

/tmp/kaeru/RestClient.java

package kaeru;

        this.password = password;
    }

    //アカウントとパスワード設定時はBasicAuthFilterを付加してClient生成
    private Client getClient() {

            case 201:   // CREATED

            }
        } catch (URISyntaxException e) {
