How about this:

ngOnInit(){
    let options = {
      param1: "param1",
      param2: "param2",
      param3: "param3"
    };

    let myQuery = 'http://someurl?'
    for (let entry in options) {
        myQuery += entry + '=' + encodeURIComponent(options[entry]) + '&';
    }

    // remove last '&'
    myQuery = myQuery.substring(0, myQuery.length-1)

    window.location.href = myQuery;
}

myQuery value is ?param1=param1¶m2=param2¶m3=param3.
