jQuery AJAX在200成功响应上失败404

Question

I have a simple API, written in Rails, which should be used with AJAX from jQuery.

Here is how my controller method looks like:

  user = User.find_by_email_and_password(params[:email], params[:password])
  if ! user
    user = User.new
    user.email = params[:email]
    user.password = params[:password]
    user.save
  end

  respond_with user, status: 200

This is the AJAX handler:

$.ajax({
    url: Service.url + 'login.json',
    data: {
      email: 'email@server.com',
      password: 'pass'
    },
    type: 'POST',
    dataType: 'json',
    success: function(json) {
      if (json.id) {
        this.is_logged_in = true;
        this.data = json;
        $('#finilizeModal').modal('show');
        return $('#signInModal').modal('hide');
      }
    },
    error: function(xhr, status) {
      return alert('An error occured while executing AJAX request');
    },
    complete: function() {}
  });

The following just alerts: An error occured while executing AJAX request and has an error code of 404. But the Chrome Inspector shows that the request was successful and the output is a valid JSON.

What am I doing wrong?

尝试生成在Rails中不带'.json'的页面，因为：Rails中的URL'/somepage?email=emsil&password=pass.json'，jQuery发送'/somepage.json?email=email&password=pass'。
