Is there function like php setcookie . If not then how?
EDITED:
yaws_api:setcookie("lang","lang_value", "/"),
yaws_api:find_cookie_val("lang", (A#arg.headers)#headers.cookie),
find_cookie_val returns empty string because setcookie didnt set coockie.
Finally i did it through http header:
out(A) ->
% read
yaws_api:find_cookie_val("lang", (A#arg.headers)#headers.cookie),
% send to browser
[{header,["Set-Cookie:","lang=ruler;","expires="++to_cookie_expire(60*60*24*30)++";"]},
{html, ...}]
end.
to_cookie_expire(SecondsToLive) ->
Seconds = calendar:datetime_to_gregorian_seconds(calendar:local_time()),
DateTime = calendar:gregorian_seconds_to_datetime(Seconds +
SecondsToLive), httpd_util:rfc1123_date(DateTime).
This site provides some example code for yaws and setting cookies:

In a Laravel 6x project I'm working on I'm setting a cookie with:
Cookie::queue('remember_me', json_encode(['uid' => $user->id, 'token' => $token]),2628000);
I'm reading the cookie and decrypting it with:
$cookies = Crypt::decrypt(Cookie::get('remember_me'),false);
This works well, except that the value of $cookies has an extra pre-pended string and a | delimiter in it:
e80cd502fec2a621b624ead8eb1cc91a2e94846b|{"uid":872,"token":"l1214065120208k"}
I can work with that obviously to get what I need but I have been unable to find anything on why that string and | are being prepended to the cookie. Any explanation or documentation link?
I did find another thread here with a similar question but no answer:
How to decrypt cookies in Laravel 8
I also found a thread suggesting that Laravel 8 adds the session_id to the cookie string. Is that what I'm seeing here?
Thanks,
Michael
This value looks to be an HMAC-SHA1 of the cookie name with v2 appended to the end.
This logic is implemented in the CookieValuePrefix class in Laravel and the code looks like so:
public static function create($cookieName, $key)
{
return hash_hmac('sha1', $cookieName.'v2', $key).'|';
}
This is used in the EncryptCookies middleware when encrypting and decrypting accordingly. The relevant source code is:
// in decrypt() function
$hasValidPrefix = strpos($value, CookieValuePrefix::create($key, $this->encrypter->getKey())) === 0;
$request->cookies->set(
$key, $hasValidPrefix ? CookieValuePrefix::remove($value) : null
);
// in encrypt() function
$this->encrypter->encrypt(
CookieValuePrefix::create($cookie->getName(), $this->encrypter->getKey()).$cookie->getValue(),
static::serialized($cookie->getName())
)
I put this logic into a CyberChef page here to test it out with some local cookies I had and verify the output matches and it did. If you go there and plug in your app key (preferable a disposable one) you should see it output the hash value you have in your question.
Using AngleSharp v 0.9.9, I'm loading a page with OpenAsync which sets a bunch of cookies, something like:
var configuration = Configuration.Default.WithHttpClientRequester().WithCookies();
var currentContext = BrowsingContext.New(configuration);
// ....
var doc = context.OpenAsync(url, token);
This works fine and I can see the cookies have been set. For example, I can do this:
var cookieProvider = currentContext.Configuration.Services.OfType<ICookieProvider>().First() as MemoryCookieProvider;
And examine it in the debugger and see the cookies in there (for domain=.share.state.nm.us)
Then I need to submit a post:
var request = new DocumentRequest(postUrl);
request.Method = HttpMethod.Post;
request.Headers["Content-Type"] = "application/x-www-form-urlencoded";
request.Headers["User-Agent"] = userAgent;
//...
Which eventually gets submitted:
var download = loader.DownloadAsync(request);
And I can see (using Fiddler) that it's submitting the cookies from the cookieProvider.
However, I need to add a cookie (and possible change the value in another) and no matter what I try, it doesn't seem to include it. For example, I do this:
cookieProvider.Container.Add(new System.Net.Cookie()
{
Domain = ".share.state.nm.us",
Name = "psback",
Value = "somevalue",
Path = "/"
});
And again I can examine the cookieProvider in the debugger and see the cookie I set. But when I actually submit the request and look in fiddler, the new cookie isn't included.
This seems like it should be really simple, what is the correct way to set a new cookie and have it included in subsequent requests?
I think there are two potential ways to solve this.
either use document.Cookie for setting a new cookie (would require an active document that already is at the desired domain) or
Use a Filter for getting / manipulating the request before its send. This let's you really just change the used cookie container before actually submitting.
The Filter is set in the DefaultLoader configuration. See https://github.com/AngleSharp/AngleSharp/blob/master/src/AngleSharp/ConfigurationExtensions.cs#L152.
I've been using Instagram's undocumented API https://www.instagram.com/<user>/?__a=1 to get a public user feed on a website. Since a while now, this is not working anymore, probably because Facebook removed it. Is there an other way to get the data of an instagram account in a easy way?
I built a small server which does that transformation. You'll receive the instagram data as before with ?__a=1 (as JSON ) - have fun 😊
https://www.instapi.io/u/<username>
https://www.instapi.io/u/appwithus
EDIT 12/2020: Unfortunately the service is no longer available
Edit 15/03 NOT WORKING ANYMORE Seems like instagram changed again their API, now it gives a CORS error.
As of 2 february 2021, I have found a solution
Instead of using https://www.instagram.com/username/?__a=1 which it asks for a login.
Justing adding a /channel seems to make it work, like so:
https://www.instagram.com/username/channel/?__a=1
There is a JSON data in https://www.instagram.com/<user>/.
You can use regexp to find what you need.
Sample
// This regexp gets widest possible dict around "profile_pic_url"
// but inside tag <script type="text/javascript">...</script>
let r = new RegExp('<script type="text\/javascript">' +
'([^{]+?({.*profile_pic_url.*})[^}]+?)' +
'<\/script>');
let source = document.documentElement.outerHTML;
let jsonStr = source.match(r)[2];
let data = JSON.parse(jsonStr);
console.log('data', data);
let oldVariantOfData = data['entry_data']['ProfilePage'][0];
console.log('oldVariantOfData', oldVariantOfData);
The same response is attached in the html response of the profile url, I perform this temporal solution (when I can't use the API) in python:
url_recent_media = 'https://www.instagram.com/%s/' % instagram_id
response = urllib2.urlopen(url_recent_media)
insta_html = response.read()
insta_html_split = insta_html.split('"ProfilePage":[')
if len(insta_html_split) > 1:
insta_html_split_2 = insta_html_split[1].split(']},"gatekeepers"')
if len(insta_html_split_2) > 1:
json_dict = json.loads(insta_html_split_2[0])
I hope this help you.
you can try without using instagram API.
import json, urllib2
img_dicts = []
url = 'https://www.instagram.com/{}/'.format(instagram_username)
try:
r = urllib2.urlopen(url, timeout=10.0)
instagram_html = r.read()
instagram_html_data = instagram_html.split('"ProfilePage":[')
if len(instagram_html_data) > 1:
instagram_html_final_data = instagram_html_data[1].split(']},"gatekeepers"')
if len(instagram_html_final_data) > 1:
json_dict = json.loads(instagram_html_final_data[0])
media = json_dict['graphql']['user']['edge_owner_to_timeline_media']['edges']
for obj in media:
img_dicts.append({
'id': obj['node']['id'],
'caption': obj['node']['edge_media_to_caption']['edges'][0]['node']['text'],
'imgurl_standard': obj['node']['display_url'],
'imgurl_lower': obj['node']['thumbnail_resources'][4]['src'],
'imgurl_thumb': obj['node']['thumbnail_resources'][3]['src']
})
img_dicts will give you images in different quality and caption of instagram post.
I work with Classic ASP (vbscript), I add cookies to the Response like so:
Response.Cookies("mycookie") = "var_cookie"
Then I issue a redirect to "etape2.asp" file:
Response.Redirect("etape2.asp");
On the new page ("etape2.asp") that I am redirected to, I try to retrieve a cookie like so:
Request.Cookies("mycookie");
But the cookie is empty!!
Can anyone think of why the cookies are not being passed?
Might be worthwhile making sure you have set an expiry for the cookie far enough in advance, and set the path to which it applies:
So, in e.g. etape1.asp, do this...
var_cookie_mycookie = "this is the contents of mycookie"
response.cookies("mycookie").expires = now + 1
response.cookies("mycookie").path = "/"
response.cookies("mycookie") = trim(cstr("" & var_cookie_mycookie))
response.redirect "etape2.asp"
And in etape2.asp, do this...
var_cookie_mycookie = trim(cstr("" & request.cookies("mycookie")))
response.write "<p>Value of 'mycookie' cookie: " &_
server.htmlencode(var_cookie_mycookie) &_
"</p>"
I am hoping someone can help get me in the right direction...
I am using Powerbuilder 12 Classic and trying to consume a Oracle CRM OnDemand web service.
Using Msxml2.XMLHTTP.4.0 commands, I have been able to connect using https and retrieve the session id, which I need to send back when I invoke the method.
When I run the code below, I get the SBL-ODU-01007 The HTTP request did not contain a valid SOAPAction header error message. I am not sure what I am missing??
OleObject loo_xmlhttp
ls_get_url = "https://secure-ausomxxxx.crmondemand.com/Services/Integration?command=login"
try
loo_xmlhttp = CREATE oleobject
loo_xmlhttp.ConnectToNewObject("Msxml2.XMLHTTP.4.0")
loo_xmlhttp.open ("GET",ls_get_url, false)
loo_xmlhttp.setRequestHeader("UserName", "xxxxxxx")
loo_xmlhttp.setRequestHeader("Password", "xxxxxxx")
loo_xmlhttp.send()
cookie = loo_xmlhttp.getResponseHeader("Set-Cookie")
sesId = mid(cookie, pos(cookie,"=", 1)+1, pos(cookie,";", 1)-(pos(cookie,"=", 1)+1))
ls_post_url = "https://secure-ausomxxxx.crmondemand.com/Services/Integration/Activity;"
ls_response_text = "jsessionid=" + sesId + ";"
ls_post_url = ls_post_url + ls_response_text
loo_xmlhttp.open ("POST",ls_post_url, false)
loo_xmlhttp.setRequestHeader("COOKIE", left(cookie,pos(cookie,";",1)-1) )
loo_xmlhttp.setRequestHeader("COOKIE", left(cookie,pos(cookie,";",1)-1) )
ls_post_url2 = "document/urn:crmondemand/ws/activity/10/2004:Activity_QueryPage"
loo_xmlhttp.setRequestHeader("SOAPAction", ls_post_url2)
loo_xmlhttp.send()
ls_get_url = "https://secure-ausomxxxx.crmondemand.com/Services/Integration?command=logoff"
loo_xmlhttp.open ("POST",ls_get_url, false)
loo_xmlhttp.send()
catch (RuntimeError rte)
MessageBox("Error", "RuntimeError - " + rte.getMessage())
end try
I believe you are using incorrect URL for Login and Logoff;
Here is the sample:
https://secure-ausomxxxx.crmondemand.com/Services/Integration?command=login
https://secure-ausomxxxx.crmondemand.com/Services/Integration?command=logoff
Rest of the code looks OK to me.
I have run into similar issues in PB with msxml through ole. Adding this may help:
loo_xmlhttp.setRequestHeader("Content-Type", "text/xml")
you need to make sure that the your value for ls_post_url2 is one of the values that is found in the wsdl file. Just search for "soap:operation soapAction" in the wsdl file to see the valid values for SOAPAction.
