为什么 WSO2 APIManager 的 API 无法调用成功？

Question

我想测试APIManager的API，我使用工具soapUI通过端点调用UserAdmin服务的接口listAllUsers https://host:8243/services/UserAdmin.UserAdminHttpsSoap11Endpoint，并且我还在基本认证头中添加了admin用户/密码。但我无法得到结果。

APIManager 控制台输出的错误信息如下。

根据报错信息，好像admin用户/密码不对，但是当我用同一个方法调用DSS的同一个API时，就OK了！

我不知道为什么。

Answer 1

尝试将端口更改为 Servlet 端口。那么端口应该是 9443 而不是 8243。

https://host:9443/services/UserAdmin.UserAdminHttpsSoap11Endpoint
