Optaplanner 7.9.0 无法取消编组输入字符串 调用 REST API 时出错

Question

嗨，我是optaplanner的新手，所以在wildfly 11上安装了最后一个版本的kie-wb和kie-server(7.9(后，我正在尝试示例项目，以了解如何使用optaplaner功能。我安装了两个内置示例：optaCloud和Employee_rostering示例。有了第一个，一切都好了，安装、配置和部署到kie服务器，并在REST客户端使用SOAPUI调用RESTapi(还提交了解决方案的xml|json示例数据(。

对于第二个，安装和部署也可以，但主要问题是在官方文档中没有样本数据(xml|json(，通过邮寄提交给求解器以请求解决方案。

经过谷歌搜索，我终于在红帽子网站上找到了这篇文章(员工名册样本(。。。阅读内容，我可以看到这是kie-wb样本项目中的相同样本(数据模型、数据对象和drl规则(；员工名册"我在上面用过。因此，我尝试使用本文中的xml数据示例向求解器提交解决方案请求。问题似乎出在这个xml样本数据上，事实上，当我以这个xml为主体提交带有SOAPUI的rest请求时，kie服务器的响应是带有主体的500 Internal Server Error：

<data contentType="text/plain;charset=UTF-8" contentLength="2950">
<![CDATA["Unexpected error during processing: Can't unmarshall input string: 
<employeerostering.employeerostering.EmployeeRoster>
<employeeList>
<employeerostering.employeerostering.Employee>
<name>John</name>
<skills>
....

有人对此有经验吗？非常感谢任何建议/信息

感谢

Answer 1

[SOLVED]REST请求必须包含以下标头

authorization: Basic cGxhbm5lcjpQbGFubmVyMTIzXw==
X-KIE-ContentType: xstream
content-type: application/xml

在SOAP-UI中，我添加了一个自定义头X-KIE-ContentType: xstream(auth-basic和content-type已经可以了(。这是我成功提交给求解器的示例XML正文内容
