Use JS to read user profile properties from the Add-in program in SharePoint 2013

After countless experiments, only this program can run normal, code paste out of pure jsom, in my experimental environment always return unknown error, for this simple task, I have been engaged for 2 days, but finally made out, using various methods, there is also the use of code.

functiongetuserinformation (loginname,propertyname) {$.ajax ({Url:appweburl+ "/_api/sp.userprofiles.peoplemanager" + "/getuserprofilepropertyfor ([email protected],propertyname= '" +proper Tyname+ "')", type:"GET", Data:"@v=" + encodeuricomponent (Logintype + loginName) + "'", headers: {"Accept": "Application/json;odata=verbose"}, Success:function(Result) {D=eval (result); $("#ecPhone"). Val (d.d.getuserprofilepropertyfor); }, Error:function(Error) {alert ("Error" +error.responsetext); }});}

In my environment, var logintype = "i:0#.w| Ad\\ ";

is actually the identity of the declaration string, the last D.d.getuserprofilepropertyfor, is the return value, I do not know why to write this.
