I'm trying to request page on remote server using PHP-CURL which returns data on https only.
The user agent must be mobile browser.
I've set below user agent rite now :
Mozilla/4.1(compatible;Symbian OS;MSIE 5.0;Nokia 3650;424)Opera 6.10 [en]
When i request page using above user agent, it says my browser does not support https. If anyone knows which user agent i shall set in my curl request then please help me.
Thanks in advance.
Try Android Browser user agent
Mozilla/5.0 (Linux; U; Android 2.1-update1; ru-ru; GT-I9000 Build/ECLAIR) AppleWebKit/530.17 (KHTML, like Gecko) Version/4.0 Mobile Safari/530.17
Or Opera Mini
Opera/9.60 (J2ME/MIDP; Opera Mini/4.2.14912/812; U; ru) Presto/2.4.15

I'm having a strange issue, which I find difficult to summarize in a title.
First:
I have a webpage, where people need to be logged in.
I have a Excel document, with links to the webpage.
The problem:
When people are logged in, and they click on the link in the Excel document. The webpage tells them that they are not logged in.
What I found so far:
I'm using Office on Mac and I don't have any issues.
People using Office on Windows do have issues.
I think the issue is due to SESSIONS, that might be the reason why users aren't logged in while they should be.
I did some tests.
Every URL goes through index.php
index.php
<?php
session_start();
file_put_contents('log.txt', microtime().': SERVER '.print_r($_SERVER, true).PHP_EOL, FILE_APPEND);
exit;
Now when I click the link from Office on Mac (NO ISSUES!!!), I get a dump of the variable $_SERVER. Two important variables:
[HTTP_USER_AGENT] => Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36
[HTTP_COOKIE] => PHPSESSID=77lpqmdmvskv33d2ddsdlfs5q7; rememberme=1%3Ae79e92271e7e05a5ee5679b659b3cb5cbb61e60d96c158f4648960136b175164%3Accdee80c3e42705fcd7e8c234525beda86d27394653dfdfb42bdd3ec98592ca1
You can see the browser (Chrome) and the cookie, which contains a rememberme cookie for login.
Now, when I do the same by clicking on a link in Excel on Windows, I get the $_SERVER variable printed three times in the log file!
First:
[HTTP_USER_AGENT] => Microsoft Office Excel 2014
[HTTP_COOKIE] => PHPSESSID=0ivlfjf49j4b82858tstc2lmm3; PHPSESSID=tv6gs33j721d0tmm3rrjdoho45
Notice the user agent and no rememberme cookie.
Second:
[HTTP_USER_AGENT] => Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 10.0; WOW64; Trident/7.0; .NET4.0C; .NET4.0E; .NET CLR 2.0.50727; .NET CLR 3.0.30729; .NET CLR 3.5.30729; ms-office)
[HTTP_COOKIE] => PHPSESSID=0ivlfjf49j4b82858tstc2lmm3
Notice, still no chrome browser and rememberme cookie.
Third:
[HTTP_USER_AGENT] => Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36
[HTTP_COOKIE] => PHPSESSID=3s0hvtssghk7uomvkpb5k70tc2; rememberme=1%3Aa9bd74ad58a0d7075c27108be1adbd26ba6d18f6e8b39073152d6780131ffe70%3A643852f8636c76c0bfc4017ec7fe3eab98dd57f5bcfdf86f0e37b5ec28a0c0ef
Finally user agent is Chrome and rememberme cookie is set.
So, it's getting a long story. But clicking on the link in Excel from Windows, it does strange things. Anyone an idea what is happening?
Oke, I found the problem. Below an answer from superuser.com
The URL you're using needs some more information from a cookie to
display the search results rather than the search page. Paste the URL
into a different browser (or remove your cookies) and you'll get the
same results.
Clicking a URL in Excel seems to open it in your default browser. But
that's not really true. Before opening it in your browser, Excel first
runs Microsoft Office Protocol Discovery. This uses a Windows/Internet
Explorer component to determine if the URL works. (It does not
identify itself as Internet Explorer, but as "User Agent: Microsoft
Office Existence Discovery".) And if the results are (somehow) okay
then it will open the result of that check in your default browser.
Lacking the cookies (more precisely: lacking a session), GoDaddy gives
that Internet Explorer component some redirect. And the result of that
is opened in your default browser. That's the URL you're seeing.
Most likely your default browser is not Internet Explorer? Then
pasting the URL into IE directly and clicking it, to get the cookies,
might then also make the link work from Excel. (Just for testing; it's
not a permanent solution.)
You will have more luck using a URL that does not rely on some hidden
information from a cookie, like
http://www.godaddy.com/domains/search.aspx?domainToCheck=superuser.com
Source: https://superuser.com/a/445431
So to solve this issue:
When Excel checked the link, it gets redirected to '/login' because it wasn't logged in. And finally that URL is the URL Excel opens in the real browser.
So I changed the login script and a user will not be redirected to '/login', but stay on the same URL and it will be shown the login form if not logged in. Excel now opens the original URL an if the user is logged in, it will see the page. If it is not logged in, the login form will be shown.
How would I force HTTP (Not HTTPS), while getting the source code of: http://www.youtube.com/watch?v=2YqEDdzf-nY?
I've tried using get_file_contents, but it goes to HTTPS.
There is no way, because google forces you to use https. It will not accept longer unsecure connection.
They even start to downrank websites, which are not on SSL.
As for your Comment, i have done a little bit more research.
Maybe it is depended on the user-agent. I have no time to confirm this.
Try CURL with this User Agent:
Mozilla/5.0 (Windows NT 6.1; WOW64; rv:24.0) Gecko/20100101
Well, I have the following problem. I made a tool that checks the status of a website.
For example if I enter www.youtube.com it will say
http://www.youtube.com HTTP/1.0 200 OK
and for a website with a redirect it will say:
http://www.imgur.com HTTP/1.1 302 Moved Temporarily
http://imgur.com/ HTTP/1.1 200 OK
Alright, this works just as it should, however I would like to make it so that you can select the user-agent. So for example Android or something. Because youtube on android will redirect to m.youtube.com
I made a dropdownlist already with different user-agents and now what I don't know is how to change a user-agent. When I search google it just gives me browser plugins or addons.
I hope someone knows of a way to do this.
Thanks in advance!
You can send a CURL request and change the user agent like this.
curl_setopt($ch,CURLOPT_USERAGENT,'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');
Using Php is it possible to detect exact OS even if the browser agent value is altered?
Here is the case
If someone override Firefox useragent value using "general.useragent.override"
Actual: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:12.0) Gecko/20100101 Firefox/12.0
Override: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_3) AppleWebKit/534.55.3 (KHTML, like Gecko) Version/5.1.3 Safari/534.53.10
$_SERVER['HTTP_USER_AGENT'] value will be totally fake. it's not useful even to detect correct Operating System.
Is there any Php solution in this situation?
Thanks.
No, it is not possible. The only information you have is that supplied by the User-agent header, and if a user wants to send false information there is nothing you can do to detect it.
You can still use JavaScript to find the screen size but not the os this is how to
<script type="text/javascript">
document.write(screen.width+'x'+screen.height);
</script>
but this can be changed by the client anyway as its on the client side on ios there is one way by setting up a mobile management profile temp to very the device but thats a lot of work for the client so only do that if you have to
But in most cases you cannot very its not mod
i am trying to change user agent in php.ini file as follows.
user_agent="Mozilla/5.0 (iPhone Simulator; U;
CPU iPhone OS 4_3_2 like Mac OD X; en-us)
AppleWebKit/535.17.9(KHTML, like Gecko)
Version/5.0.2 Mobile/8H7Safari/6533.18.5"
after that when i check user agent in my php file with following command and this show that user agent has not been change.
echo $_SERVER['HTTP_USER_AGENT'];
this shows : Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0)
which is still not iphone user agent which i have set in php.ini file.
so please help me how to set user agent in php.ini file which switch my browser request as iphone browser request.
i have also tried with following command.
ini_set('user_agent', 'Mozilla/5.0 (iPhone Simulator; U;
CPU iPhone OS 4_3_2 like Mac OD X; en-us)
AppleWebKit/535.17.9 (KHTML, like Gecko) Version/5.0.2
Mobile/8H7 Safari/6533.18.5');
this also gives same result and i am unable to switch to iphone browser request.
I'm afraid you've misunderstood. The user_agent setting in php.ini has nothing to do with $_SERVER['HTTP_USER_AGENT].
The setting in php.ini is used as a default for when PHP does HTTP requests, for example with cURL.
$_SERVER['HTTP_USER_AGENT'] contains the user agent that the web browser sent along with its request to your PHP script. That's why it's showing MSIE because you're viewing the page in MSIE.
If you want to send a different user agent from your browser, you'll have to use a browser plugin unless the browser allows you to freely modify it. For example like this.
