Cannot login to website using createHTTPClient

I know that there are a lot of similar questions so I apologise, but I have not found a solution to my specific problem. Most of the queries I have seen have related to Android, validating with get or header authentication.

I am using Titanium mobile to create an iPhone application and I need to log in to a website. The website uses a simple login form (email address and password) that is submitted using POST.

I can submit information to other forms on the same site that use POST but do not require you to be logged in but I cannot get the login form to work.

When I submit the form I get exactly the same page back in responseText, no login failure message or errors, it is just as if I have refreshed the page. I get a readyState 4 and responseCode 200.

The code I am using is as follows:

var xhr = Titanium.Network.createHTTPClient();

xhr.onreadystatechange = function() {
    if (this.readyState == 4) {
        temptext = this.responseText;

xhr.setRequestHeader( 'Content-Type','application/x-www-form-urlencoded' );

I added the setRequestHeader following advice in other posts, it makes no difference wether it is there or not. I have also tried with the form field names both enclosed in quotes and without, again from reading other posts.

I suspect that this is a problem with the website and not specific to Titanium, but unfortunately the website is not mine and I suspect the designer has used an off the self OS CMS so will probably not have a clue as to what additional requirements the login processing has.

If anyone has had the same problem I would be very grateful for advice.

Many thanks

  • Could it be to do with your website code creating a session for the user when they are logged in or not. I'm in the process of creating an MMO, all I do is send login credentials along with every request. If the login details are correct my server sends the requested info back, else it send a not logged message to handle by the app.

    • It's not a problem with session cookies as the account has definitely not been verified. I just get a blank form back.

      I have made some progress, I missed that the form had a hidden field and the submit button is not named submit. The form looks like this:

      <form name="login" method="post" action="/account/login/">
      <input name="email" id="email" type="text" class="input" size="30" value="" />
      <input name="password" id="password" type="password" class="input" size="30" />
      <input name="login" type="submit" value="Login" class="button" />
      <input type="hidden" name="login_page" value="http://www.website.co.uk/" />

      So I have changed the code as follows:

          xhr.setRequestHeader( 'Content-Type','application/x-www-form-urlencoded' );

      It is now trying to login, if I put an incorrect password in I get back a page informing me that the password is incorrect. However, if I put the correct password in I get an error message "Error Domain=ASIHTTPRequestErrorDomain Code=9 The request failed because it redirected too many times". I get the same message if I omit the page redirect form element.

      One step forward…!
