WSO2 API Manager /services/...抛出 NullPointerException
WSO2 API Manager /services/... throw a NullPointerException
我在 Windows 2012 R2 服务器和所有仪表板 URL 上安装了 WSO2 API 管理器 运行，例如 https://localhost:9443/store、https://localhost:9443/carbon,https://localhost:9443/publisher 工作正常。但是当我配置和部署（在 carbon.super 租户中）示例 WeatherAPI Web 服务并尝试通过 /services/... URL 访问它时，即：
https://localhost:9443/services/weather/1.0.0/*?q=Amsterdam
我收到以下错误页面 returned:

当我在租户中创建自己的 Web 服务并部署它时，我遇到了同样的错误。所以我可能配置错误，但不知道去哪里找。
/services/... 以下的所有路径似乎 return 此错误页面。我检查了 [WSO2]/repository/logs 目录中的日志文件，但它们没有显示任何错误。
您正在尝试从 servlet 端口 9443 访问服务。尝试使用 8280 port . However, the endpoint of the API in APIM does not look like as you mention. Check the example given in the official WSO2 documentation
