JBPM中如何设置HTTP请求headers

Question

我想在 JBPM 中设置 HTTP 请求 headers。我正在尝试来自邮递员的请求并且它工作......我已经使用 java 做了一个简单的例子并且它的作品现在我需要发送 headers 例如邮递员，存在类似：

workItem.setParameter("Headers", Headers);

代码有效：

import java.util.Map;
import org.drools.core.process.instance.impl.WorkItemImpl;
import org.jbpm.process.workitem.rest.RESTWorkItemHandler;
import org.kie.api.runtime.process.WorkItem;
import org.kie.api.runtime.process.WorkItemHandler;
import org.kie.api.runtime.process.WorkItemManager;

public class test {

    public static void main(String[] args) {
        test t=new test();
        System.out.println(t.getFiles("xxx","xxx","xxx","xxx"));
    }

    public String getFiles(String user,String pwd,String site,String path) {
        String result="Error getFiles ";
        try {           
            RESTWorkItemHandler handler = new RESTWorkItemHandler();
            WorkItemImpl workItem = new WorkItemImpl();
            workItem.setParameter("Url", "https://mywebsite.com/sharing/api/v1/files"+"?path="+path);
            workItem.setParameter("Method", "GET");
            // workItem.setParameter("Headers", Headers); Exists ?
            WorkItemManager manager = new TestWorkItemManager(workItem);
            handler.executeWorkItem(workItem, manager);
            int responseCode = (Integer) workItem.getResult("Status");      
            if(responseCode==200) {
                result = (String) workItem.getResult("Result");
            }   
        }catch(Exception e) {
            result+=e.getMessage();
        }
        return result;
    }   
}

class TestWorkItemManager implements WorkItemManager {    
    private WorkItem workItem;

    TestWorkItemManager(WorkItem workItem) {
        this.workItem = workItem;
    }

    @Override
    public void completeWorkItem(long id, Map<String, Object> results) {
        ((WorkItemImpl)workItem).setResults(results);        
    }

    @Override
    public void abortWorkItem(long id) {}

    @Override
    public void registerWorkItemHandler(String workItemName, WorkItemHandler handler) {

    }

}

Answer 1

经过小小的研究，executeWorkItem 方法似乎可以处理参数 "Headers"。内容应如下所示：

"HeaderName=HeaderValue;SecondHeaderName=SecondHeaderValue"

所以整个方法调用：

workItem.setParameter("Headers", "usr=yourUsr;pwd=yourPwd");
