How to tell if site uses forms-authentication - forms-authentication

Can anybody tell me if the following site uses forms-authentication or something else?
http://www.hammernutrition.com/forums/memberlist.php?mode=viewprofile&u=1323

Yes it does. View the source of the page and do a search for password. Forms-based authentication apps generally have login code that looks like this:
<form action="/path/to/login_handler" method="post">
<input type="text" name="username">
<input type="password" name="password">
<input type="submit" value="login">
</form>

Send amp-form data to mailchimp with Nextjs

I have a a standard amp form, with an email input, and a sumbit input, and a mailchimp endpoint.
<form
method="post"
action-xhr={`https://${DATACENTER}.api.mailchimp.com/3.0/lists/${LIST_ID}/members`}
target="_top"
>
<fieldset>
<input
type="email"
name="email"
placeholder="Enter your email"
required
className="email-input"
/>
<input
type="submit"
value="Sign Up"
className="sign-input"
/>
</fieldset>
</form>
now the problem is, i need to configure headers,to provide an Authorization API key, and to setup cors.
AMP requires to use xhr to send data. and i have no idea on how to do that inside nextjs, or a serverless function for that matter.
Maybe try this solution - https://www.miguoliang.com/how-to-build-a-mailchimp-embed-form-in-amp-pages.html
You'll have to make an API using mailchimp's python library and provide the credentials and use that API to post data from the form.

Logging in and scraping a site like ft.com with BeautifulSoup

I have this url: https://www.ft.com/content/87d644fc-73a4-11e7-aca6-c6bd07df1a3c
It corresponds to an article that requires signing up. I signed up and can see the content in my browser. However when I use this code with the url above:
soup = BeautifulSoup(urllib2.urlopen(url), 'lxml')
with open('ctp_output.txt', 'w') as f:
for tag in soup.find_all('p'):
f.write(tag.text.encode('utf-8') + '\n')
Especially, it redirects me on the signup page. Is there any way to be logged in to have access to the article when scraping?
Here are the basics.
Go to the login page. If you use the Chrome browser you can position your mouse over the email input area and use the context menu (in Windows) and then its 'Inspect' entry to reveal the form element that will be used to submit your email address. It looks like this.
<form name="enter-email-form" action="/login/submitEmail" class="js-email-lookup-form" method="POST" data-test-id="enter-email-form" novalidate="true">
<input type="hidden" name="location" value="https://www.ft.com/content/87d644fc-73a4-11e7-aca6-c6bd07df1a3c">
<input type="hidden" name="continueUrl" value="">
<input type="hidden" name="readerId" value="">
<input type="hidden" name="loginUrl" value="/login?location=https%3A%2F%2Fwww.ft.com%2Fcontent%2F87d644fc-73a4-11e7-aca6-c6bd07df1a3c">
<div class="lgn-box__title">
<h1 class="lgn-heading--alpha">Sign in</h1>
</div>
<div class="o-forms-group">
<label for="email" class="o-forms-label">Email address</label>
<input type="email" id="email" class="o-forms-text js-email" name="email" maxlength="64" autocomplete="off" autofocus="" required="">
<input type="password" id="password" name="password" style="display:none">
<label for="password">
</label></div>
<div class="o-forms-group">
<button class="o-buttons o-buttons--standout o-buttons--big" type="submit" name="Next">Next</button>
</div>
</form>
You will need to gather the action attribute from the form element and all the name-value pairs from the input statements. You use these in a POST request with the requests library.
You do this once for your email address and once for your password. Then you should be able to issue the GET for the URL with requests.
I must warn you that I haven't actually tried this with that particular site.
If you are to scrape a website using BeautifulSoup, I'd recommend the MechanicalSoup library. It is a very lightweight layer on top of BeautifulSoup (to parse HTML) and requests (to fetch pages), but it will deal for you with things like filling-in a form properly (i.e. what you need here), following relative links, ...
MechanicalSoup is also limited in the sense that it doesn't interpret JavaScript code, hence won't work on a website relying on JavaScript, but it reduces the manual effort compared to using BeautifulSoup and urllib or requests directly.

Integrating a custom built form with a subscriber list provider (Aweber)

I have created my own form because every other form out there for WordPress is horrible.
div class="exc-form">
<form action="action_page.php">
<fieldset>
<div id="form_jgrsh">
First name:<br>
<input type="text" name="firstname" placeholder="Please enter first name">
<br>
Last name:<br>
<input type="text" name="lastname" placeholder="Please enter last name">
<br>
Email:<br>
<input type="text" name="email" placeholder="Please enter email">
<div class="chk_bx">
<input type="checkbox" name="concent" value="agree">By entering my information and pressing submit I agree to subscribing to the Stockhouse AND Junior Gold Report (please check box before submiting)
<br>
</div>
<input type="submit" class="submit-btn" value="Submit">
</div>
</fieldset>
</form>
It's super simple and isn't anything special. I'm under the impression PHP will be needed as well.
I use Aweber as my list provider, and I've contacted them for support and they want me to use their horrible, ugly form builder, and won't help me integrate my own form to use their list.
I've never done something like this before, so I'm looking for some guidance on how to send subscriber information to a list. Aweber offer's a list ID and most plugins I've seen require a Aweber authentication before Aweber links up to the list.

Here is the authentication list: https://labs.aweber.com/snippets/authentication

Anti-Fogery not working correctly in asp.net Razor

I have an ASP.NET Webpages Razor syntax page which all of a sudden has stopped authenticating users!
If a user tries to login to the site now the server responds with the message:
The required anti-forgery form field "__RequestVerificationToken" is not present.
Well.... It is!
Looking at the source of my login page it does add the hidden field as seen below..
<section id="loginForm">
<form method="post">
<fieldset>
<input name="__RequestVerificationToken" type="hidden" value="WgwaKIsXipJ4C8IRsaz__C_tW02ejupv8af-w3czwefo2AEacVlGs_k-lFNRfLqWr0inzHxtkEnXgPKZMvacv5u1LVfLphIP8R1JGukMZcA1" />
<legend>Sign in to Your Account</legend>
<ol>
<li class="email">
<label for="email" >Username</label>
<input type="text" id="email" name="username" />
<span class="field-validation-valid" data-valmsg-for="username" data-valmsg-replace="true"></span>
</li>
<li class="password">
<label for="password" >Password</label>
<input type="password" id="password" name="password" />
<span class="field-validation-valid" data-valmsg-for="password" data-valmsg-replace="true"></span>
</li>
<li class="remember-me">
<input type="checkbox" id="rememberMe" name="rememberMe" />
<label class="checkbox" for="rememberMe">Remember me?</label>
</li>
</ol>
<input type="submit" value="Sign in" />
</fieldset>
</form>
</section>
To create this field I use #AntiFogery.GetHTML() and in the post method which authenticates users I have #AntiForgery.Validate() <---- This is where the website crashes and shows me the aforementioned error.
I don't know if this helps. but if i remove the validation all together (Server and client) I get a 403 error when attempting to login to the website.
Oddly enough this has happened all of a sudden without any intervention?
Finally, On my local machine this does not happen. Only when hosted on IIS 8
I have finally discovered the issue with the IIS Server!
On my webserver I have a tool called ModSecurity Installed that was obviously interfering with my POST requests.
By adding the line, <ModSecurity enabled="false" />, into the web.config of the site everything was returned to its original state.
I hope this helps anyone else in the future with this issue

Posting data to ASP.NET application

I have an application into which I wish to allow users to enter login details for their own websites. One of authentication methods is 'forms'. The way I had envisaged it working, is the users entering the method & action of their login form, and the name/value for each credential item, e.g. one for username, one for password. My application would then post this data in order to simulate a login, get the returned authentication cookie and be able to work on their site as if logged in.
In principle, this sounded like a reasonable kind of thing to do. However, as I'm sure you're aware, ASP.NET has a lot of inputs, and also hidden ones, e.g. __VIEWSTATE, which are all always posted back to the server whenever the ASP.NET form is submitted e.g. when a real user logs in. When my app tries to login however, it doesn't have the full list of inputs on that page, and their values, e.g. the always changing __VIEWSTATE.
My question: is there a way to post data to an ASPX page, posting only certain inputs, and excluding others, e.g. __VIEWSTATE?
If the page were, say, PHP it would probably look like this:
Ex. 1:
...
<div id="header">
<form action="search.php" action="POST">
<div id="search">
<input type="text" name="query" id="SearchQueryText" value="Search query" />
<input type="button" name=submit" id="SearchSubmitButton" value="Search!" />
</div>
</form>
<form action="login.php" action="POST">
<input type="text" name="uname" id="Username" value="Username" />
<input type="text" name="passwd" id="Password" value="Password" />
<input type="button" name=submit" id="LoginSubmitButton" value="Login" />
</form>
...
</div>
...
in ASP.NET Web Forms, however, through the use of server controls, it'd probably look like:
Ex. 2:
...
<body>
<form name="AspNetForm" method="post" action="/Products/SomethingOrOther.aspx" id="Form" enctype="multipart/form-data">
<div id="header">
<div id="search">
<input type="text id="ctl00$SearchComponent$SearchBox" name="ctl00$SearchComponent$SearchBox" value="Search query" />
<input type="submit" id="ctl00$SearchComponent$SearchSubmit" name="ctl00$SearchComponent$SearchSubmit" value="Search!">
</div>
<div id="login">
<input type="text id="ctl00$LoginComponent$Username" name="ctl00$LoginComponent$Username" value="Username" />
<input type="text" id="ctl00$LoginComponent$Password" name="ctl00$LoginComponent$Password" value="Password">
<input type="submit" id="ctl00$LoginComponent$LoginSubmit" name="ctl00$LoginComponent$LoginSubmit" value="Login">
</div>
</div>
...
</form>
</body>
...
With example 1, submitting the login form is a simple case of POSTing uname=something&passwd=somethingelse to login.php, however, in ASP.NET, because all inputs are wrapped in a 'global' <form>, to submit the login inputs, you have to submit the global form, and therefore all the inputs.
So what I'm after, is a way to submit only certain inputs in that global form, e.g. not __VIEWSTATE, which we can't know without probing the page beforehand.
You can use AJAX to post back the values to a specific page. In general, Web Forms is designed to post back all data on the page when you trigger a server side event. You then choose which elements/values to use in your code. If you don't want to use view state on a element, you can disable it (e.g. EnableViewState=False).
You can use asp.net page same as asp classic.
In html action you can put the aspx page from and then you have to take that.
then you can use request object of asp.net to retrive data from form. Same you can create a html form in string and put that via putting it into panel control.
Then you can asp.net button as submit button.
