java - How do I call a secured page from my own AppEngine web-service? -


to send html email i'd call different url of own app, have comfort of jsp rendering email-content.

to execute http-call own app first tried use "http://localhost/emailreport" url, failed dns-error. next tried external url:

string appid = apiproxy.getcurrentenvironment().getattributes()    .get("com.google.appengine.runtime.default_version_hostname").tostring(); appid = appid.substring(0, appid.indexof('.')); url url = new url("http://" + appid + ".appspot.com/emailreport");

this works, pages without security-constraints in web.xml. emailreport needs secured.

any idea how retrieve page? need use service-account-key? isn't there simple trick?

added:
want secure pages adding web.xml:

<security-constraint>     <web-resource-collection>         <web-resource-name>securename</web-resource-name>         <url-pattern>/mytask</url-pattern>     </web-resource-collection>     <auth-constraint>         <role-name>admin</role-name>     </auth-constraint> </security-constraint>

i solved using following workaround:

caller creates secret token , stores in memcache , adds header request.

endpoint reads header , compares value in memcache. if matches, processes request, otherwise returns 401.
