5.3. 使用 REST API 访问解析器

在部署或重新创建示例解析程序后，您可以使用 REST API 访问它。

您必须使用 REST API 注册 solver 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

5.3.1. 使用 REST API 注册 Solver
复制链接

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

每个解决器实例都可以一次优化一个计划问题。

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
    Copy to Clipboard Toggle word wrap

  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>
    Copy to Clipboard Toggle word wrap

5.3.2. 使用 REST API 调用 Solver

在注册解决程序实例后，您可以使用 REST API 向 solver 提交数据集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
    Copy to Clipboard Toggle word wrap

  2. 使用数据集向 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
