我开发了一个基于 tomcat-servlet 的 Web 应用程序,可以很好地在本地机器上运行。我通过向其发布 json 来发送请求:

"curl ontent-type: application/json" --request POST --data '{"username":"Piran", "password":"123", "requestedUsername":"hsn.vahedi", "requestedPassword":"111", "role":"client", "firstName":"Hossein", "lastName":"Vahedi", "phoneNumber":"09212814194"}' localhost:8080/myApp/register"

它给了我正确的 json 响应。但是当我以这种方式在 heroku 上部署我的应用程序时:https ://devcenter.heroku.com/articles/java-webapp-runner并向它发送请求,它给了我这个响应:
