Couchdb 使用用户名和密码同步访问

I have a couchdb running on a virtual linux machine. This db has cors enabled and setup. I have added an admin user and password to the db. I also have require_valid_user set to true. I am trying to sync a pouchdb in a web page with the couchdb online with the code below. If I just pass the address for the db (1 below), I get a dialog box asking for a user and password. The sync works in this example. If I try to pass the user name and password in the URL (as in 2 below), I get a sync error and the message "getCheckpoint rejected with ". Any suggestions on what I am doing wrong or another approach I should taking with this would be greatly appreciated.

谢谢

附:我可以使用用户名和密码浏览到 URL.

var remoteCouch = "http://192.168.1.7:5984/mydb";  //1
//var remoteCouch = "http://userid:password@192.168.1.7:5984/mydb"; //2
sync();

function sync() {
  var opts = {live: true};
  db.sync(remoteCouch,opts,syncError);
}
