ajax - Unable to send XMLHttpRequest via tampermonkey script with CORS enabled on server -


i have setup flask http server configured accept cors requests (for purpose of creating userscript web filter), unable send http requests via tampermonkey, following code.

// ==userscript== // @name        cors test // @namespace   john galt // @version     1 // @grant       none // ==/userscript==  var request = new xmlhttprequest();  request.open("get", "127.0.0.1:5000", false);  request.send();  alert("finished");

"finished" not alerted indicating failure of operation, , following error appears in console:

xmlhttprequest cannot load %3127.0.0.1:5000. cross origin requests supported http. rand.html:1 error: execution of script 'cors test' failed! failed execute 'send' on 'xmlhttprequest': failed load '%3127.0.0.1:5000'. error: failed execute 'send' on 'xmlhttprequest': failed load '%3127.0.0.1:5000'.     @ error (native)     @ object.eval (eval @ <anonymous> (unknown source), <anonymous>:19:9)     @ object.eval (eval @ <anonymous> (unknown source), <anonymous>:23:4)     @ e (<anonymous>:41:76)     @ eval (eval @ <anonymous> (unknown source), <anonymous>:1:24)     @ eval (native)     @ m (<anonymous>:68:246)     @ z (<anonymous>:41:92)     @ aa (<anonymous>:78:392)     @ b (<anonymous>:79:109)

i have no experience front-end point out if problem server configuration or on front-end, , if so, there workaround?

the first line problem. can use xmlhttprequest on same domain code on, can't fetch other origins.

here 1 alternative solution how fix cross origin error in extjs6?
