javascript - Jquery GET returns 200 with Content-Length=0 with CORS enabled at server -

some json info expected restful api get. browser(chrome , firefox) can obtain , display json info if restful url entered straight @ browser. same phone call turns status 200 content-length=0 in response header. here simple testing code. refresh button click triggers server; test button click triggers testing server. cors extension on chrome, on testing server successful json data. response server empty. tried enable cors on rest server running tomcat7. did not help. tried different method such getjson , ajax, results same.

$(document).ready(function(){ $("#refresh").button().click(function(){ var root = 'http://192.168.1.77:8080/aaa/api'; $.get(root + '/availableresources/list', function(data){ console.log(data); }); }); $("#test").button().click(function(){ var testurl = 'http://jsonplaceholder.typicode.com'; $.get(testurl + '/posts/5', function(data) { console.log(data); }) }); })

below response header:

http/1.1 200 ok server: apache-coyote/1.1 access-control-allow-origin: http://localhost:8008 access-control-allow-credentials: true access-control-expose-headers: access-control-allow-origin,access-control-allow-credentials cache-control: max-age=1 expires: tue, 07 apr 2015 17:24:16 gmt content-length: 0 date: tue, 07 apr 2015 17:24:15 gmt
