JSF link to external site without showing username and password in the URL

I was able to do a SSO(Single sign on) on click of external link from the code below. SSO works but username/password is seen on url. https://example.org/index.php?userLogin=user1&userPassword=pass123

                  <h:outputLink styleClass="ui-menuitem-link ui-corner-all"
                    value="https://example.org/index.php">

                    <h:outputText value="Ext Tool" />
                    <h:outputText styleClass="ui-icon ui-icon-suitcase"
                        style="float:left" rendered="#{userBean.in}" />
                    <f:param name="userLogin" value="#{userBean.user.eUser}" />
                    <f:param name="userPassword" value="#{userBean.user.ePass}" />
                </h:outputLink>

I also used tried as below...

                    <h:commandLink action="#{userBean.eSubmit()}">
                    <h:outputText value="Ext Tool" />
                    <f:param name="userLogin" value="#{userBean.user.eUser}" />
                    <f:param name="userPassword" value="#{userBean.user.ePass}" />
                </h:commandLink>

In the bean.. My coding is like this

    public void eSubmit() throws IOException{
    FacesContext fc = FacesContext.getCurrentInstance();
    fc.getExternalContext().redirect("https://example.org/index.php?userLogin=" + user.getUser() + "&userPassword=" + user.getPass());
}

Even for the above code with commandLink - UserName and password are visible in the URL. Please guide me to hide password in the URL.

Am new to JSF so please help me understand...

Solution

  • A redirect instructs the client to create a new GET request on the specified URL. That's why you see it being reflected in browser's address bar.

    As to performing a POST to an external site, you don't necessarily need JSF here. You're not interested in updating JSF model nor invoking a JSF action. Just use a plain HTML POST form.

    <form method="post" action="https://example.org/index.php">
    <input type="hidden" name="userLogin" value="#{userBean.user.eUser}" />
    <input type="hidden" name="userPassword" value="#{userBean.user.ePass}" />
    <input type="submit" value="Ext Tool" />
</form>

    If necessary, throw in some CSS to make the submit button look like a link, or some JS to let a link submit that form.
