wget/curl/session help


Hi I am a noob and just starting out with curl/wget and I don't know much PHP but I do know bash shell script, that being said, I have a demo website which performs two actions. The first action is you have to start your "work shift" (shift.php) then afterward you can do different tasks such as managing your "staff".(manage_staff.php)

I'm able to start the work shift but when I use the same session cookie as "shift.php" for "manage_staff.php" and perform an action on "manage_staff.php" The server throws and error saying "Start a shift to perform this action"

This is my code which successfully starts a work shift

Code:
wget -q -O- 'http://www.demosite/shift.php'  --save-cookies /home/pi/demositecookie.txt --keep-session-cookies --post-data "action=start_shift"
This is my code which fails to do different tasks because it requires you to start a shift.

Code:
wget -qO -  www.demosite/manage_start.php? --keep-session-cookies --load-cookies /home/pi/demositecookie.txt --post-data="actiom=get_staff_id=1" \

I think the problem is that the authentication isn't cookies-based, and I'm opening a new session with each wget call. How would I prevent that from happening (if that's what happening)?

I think what I want to do is send the HTTP request and basically "navigate" to the page, which I'd imagine is one wget call, but I really don't know how to do it.

Hi rpiboy,

I'm expecting that the problem isn't as simple as what might be a typing error in the second "code section" of your post:
Code:
--post-data="actiom=get_staff_id=1"
instead of
Code:
--post-data="action=get_staff_id=1"
If you are dealing with a web site, I would have generally expected it to be tested with a browser. Are you not providing an interactive web site with a User Interface, but instead providing a service-based facility? If not service-based, why are you testing with wget?

In general terms I can mention these items:
  1. There are various options for wget that have to do with recursion, and/or following from one place to another, which might conceivably affect a situation where two items from a web site need to work together. But whether they affect something here would depend on the details of the PHP code, and perhaps even the environment in which the PHP is operating.
  2. Often there can be some form of a "Session ID" that creates an association between multiple requests to a web site. I'm used to thinking in terms of a "PHPSESSIONID" specific to PHP-based environments.
  3. In some situations there is a requirement for a "referrer" to be specified on some requests, when going from one web site interaction to the next.

But without more specific details, it would be hard to know how or if, those considerations might apply here.

Sorry for the delay in responding, I've been very busy; Seeing how long it's been, I'm hoping you've been successful at solving the problem in the meantime.

If you've already solved the problem, please mark the thread as resolved.

If not, I should say that AFAIK, from the configuration you posted on Imgur, it looks as though the work flow should be cookie based, as configured, and you shouldn't need a "referer".

I'm guessing using "action" in the post data in the first wget and "actiom" in the second, was a temporary mistake that was since corrected. If not, please explain the difference. There seems to be a backslash at the end of the second wget command in your original post, but I don't see anything after it; is there more to the second wget command that you're using?

I'm not clear on the overall relationship between things with which you're working. I was expecting that "shift.php" and "manage_start.php" might be some of the main active components of page(s) on the web site you're testing. But this comment of yours:
Quote:

made me wonder, is there a single web site, or are you using a URL to one site, to test a second site? If there is more than one site involved, please describe the relationship between the two sites.

Given the PHP configuration, if there is one site, I would expect, with cookie usage, you would generally be able to go from one page to another on the single site. That is, unless the server can't access a directory or file as it's configured, or there's some problem within the PHP files themselves, something beyond the backslash in the second wget command, additional post data that's needed, or something that might not have been mentioned in your original post.

If you can't post the PHP files themselves, it might be possible to try to help you, if you could post the contents of the cookie files and server logs. If either or both are too large to post here, perhaps they could be posted at Imgur.

Still haven't solve it.

That was corrected.

There is no more data at the blackslash. The problem I am getting is this I can successfully start a shift on shift.php but when i use the same cookie with shift.php and navigate to manage.php it says you must start a shift.

Hi, rpiboy, and welcome to LQ.

That's not how LQ works. All information should be made publicly available on the thread so that folk will be able to use that information to solve similar problems.

You should find a way to post the relevant details here. If there is a lot of info then consider uploading it to a code hosting site and posting the link here.
