2.3.2. REST API を使用した Solver の呼び出し

Solver インスタンスを登録した後に、REST API を使用して、データセットを Solver に送信して、最適解を取得できます。

手順

  1. 以下のヘッダーを使用して HTTP 要求を作成します。 

    authorization: admin:admin
X-KIE-ContentType: xstream
content-type: application/xml

  2. 以下の例のように、データセットを含む Solver に要求を送信します。

    POST
    http://localhost:8080/kie-server/services/rest/server/containers/employeerostering_1.0.0-SNAPSHOT/solvers/EmployeeRosteringSolver/state/solving
