HTML5 OnProcessRequestComplete

I need to fetch data from the server.
But my code on a PC running well, to get to the data.
On the HTML5 has failed.
ProcessRequest returns TRUE, over a long time into the callback function, and the return value is empty.
Can someone help me? Thank you

TSharedRef HttpRequest = FHttpModule :: Get () CreateRequest ().;
HttpRequest-> SetVerb (TEXT (“GET”));
HttpRequest-> SetURL (TEXT (“…”));
. HttpRequest-> OnProcessRequestComplete () BindObject (this, & AMyActor :: Test_HttpRequestComplete);
HttpRequest-> ProcessRequest ();

After opening compiled html, you can see the server data request and data transmission
