11.3. 使用 REST API 访问解决问题

在部署或重新创建示例地址后，您可以使用 REST API 访问它。

您必须使用 REST API 注册解决器实例。然后，您可以提供数据集并检索优化的解决方案。

先决条件

11.3.1. 使用 REST API 注册 Solver

您必须使用 REST API 注册 solver 实例，然后才能使用 solver。

每个临时解决方案都能够一次优化一个规划问题。

流程

  1. 使用以下标头创建 HTTP 请求： 

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

  2. 使用以下请求注册 Solver：

    PUT
    http://localhost:8080/kie-server/services/rest/server/containers/employeerostering_1.0.0-SNAPSHOT/solvers/EmployeeRosteringSolver
    请求正文
    <solver-instance>
  <solver-config-file>employeerostering/employeerostering/EmployeeRosteringSolverConfig.solver.xml</solver-config-file>
</solver-instance>

11.3.2. 使用 REST API 调用 Solver

在注册了解决器实例后，您可以使用 REST API 将数据设置为解决方法，并检索优化的解决方案。

流程

  1. 使用以下标头创建 HTTP 请求： 

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

  2. 使用数据收集向 Solver 提交请求，如下例所示：

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