chanduxyz

Hi All,
I am working on Alfresco share.In that I have a requirement to download a file.When I download a file in share for the 1st time Alfresco Explorer is asking for admin authentication.Next time when I download it is not asking for any authentication.How can I resolve this issue(i.e 1st time also Alfresco Explorer should not ask for authentication when I download the file ). Could you please suggest me the way how to resolve it.Thanks a lot in advance

Is that out of the box code? Or is it your customization.

How did you configure Share (share-config-custom.xml)?

Thanks for reply Adei.I am uploading a file using a web script.I am recieving a download url from the server.Then when I click on that URL it is asking for admin authentication of alfresco explorer.To resolve it,I hope we need to identify for which WebScript/share components the authentication is comming.
2) now for those calls pass the authentication ticket along with the WebScript.

To get authentication ticket:
1) use the login WebScript and pass the user name and password

But I don't know how to achieve it.Could you please suggest the way.Thanks again

amandaluniz_z

How does the URL look like?

If you are uploading a file via webscript you'll need to have an authentication ticket, what you can do is append that ticket to the download URL so it looks such as:

http://my.alfresco.host:8080/alfresco/.......?alf_ticket=<my_ticket_value_here>

If that makes sense.

Keep in mind there are different authentication filters for webscripts:
* /service or /s: basic HTTP authentication
* /wcservice or /wcs: uses the user authenticated to the web client (explorer).

Thanks a lot Adei for your reply.

Can you please explain how can we get a ticket using web script (or) java based web script.and how can we add that ticket to the web script URL

amandaluniz_z

Hi chanduxyz,

You can get a ticket by colling the following webscript:

http:localhost:8080/alfresco/service/api/login?u=<username>&p=<password>

chanduxyz

Thanks Adei for your reply.I am able to get a ticket if I use "http:localhost:8080/alfresco/service/api/login?u=<username>&p=<password>".But I have some doubts here.
1)how can I append that ticket to my url dynamically
2)If I am able to append that ticket dynamically,how long that ticket will be valid.
3)If the ticket gets expire after 1 hour then I need to get a ticket and add it.It means getting a ticket one is not useful.So I need to get the ticket dynamically whenever I need.

So here my question is how can we get a ticket and append that ticket to the url dynamically

Your response is precious to me because I need to complete this issue ASAP.

Thanks in Advance

amandaluniz_z

Hi,

I'm not sure about how long is the ticket valid for…. Everything related to it you can find it here.

As you can see in there, once you get the ticket and call the download webscript, you'll need to append the ticket using the alf_ticket HTTP parameter with the ticket value.

To make sure the ticket is valid there is another webscript you can call.

http://localhost:8080/alfresco/service/api/login/ticket/{ticket}

Replacing {ticket} with the value of the ticket. If it's no longer valid you'll need to retrieve another ticket.

Hope this helps…

chanduxyz

Thanks a lot Adei for reply,

When I use "http://localhost:8080/alfresco/service/api/login?u=admin&pw=admin',I am getting the following ticket
<ticket>TICKET_ac05404b92507b3c0de118337cfb2ad2a57bccd2</ticket>
this ticket value I am appending to my download url like this ?alf_ticket=TICKET_43dcc87131e78653f0e76a7e2beb5510e11472d8.but still it is asking for authentication.

I dont know where it is wrong.

Could any body help me out please

amandaluniz_z

Which is the download URL you are using?

amandaluniz_z

I assume you are directly calling going through the web client rather than calling the download webscript…

You should use the following one for the download:
http://localhost:8080/alfresco/service/api/node/content/{store_type}/{store_id}/{id}

So it should look like:

http://localhost:8080/alfresco/service/api/node/content/workspace/SpacesStore/258819c4-337f-44ab-b532-ad89135eac8e?alf_ticket=<Your_ticket_value>

chanduxyz

Thanks very much Adei

Iam getting the download url from the webscript like this "alfresco/d/a/workspace/SpacesStore/9e4a359f-3efc-4f0b-b6c2-bb78b98504ed/selectone.ftl".
For this I am appending the ticket as follows
http://127.0.0.1:8080/alfresco/d/a/workspace/SpacesStore/9e4a359f-3efc-4f0b-b6c2-bb78b98504ed/selectone.ftl?alf_ticket=TICKET_43dcc87131e78653f0e76a7e2beb5510e11472d8.

But still it is asking for Alfresco Explorer Authentication.

amandaluniz_z

Could you use the one I posted in the previous reply instead? The one you are using goes directly to the web client (that's why is asking you for credentials).

chanduxyz

Thanks a lot Adei,

I hope I am almost there.I have used "http://localhost:8080/alfresco/service/ … lf_ticket=<Your_ticket_value>".i.e

"http://127.0.0.1:8080/alfresco/service/api/node/content/workspace/SpacesStore/9e4a359f-3efc-4f0b-b6c2-bb78b98504ed/selectone.ftl?alf_ticket=TICKET_1395001412eca3bf3bce84c349c7deb6c2fddc99'.When I enter this url,the file(selectone.ftl) which I want to download is opened.it is not getting downloaded.

Could you please guide me is there any way to download the file(selectone.ftl).

chanduxyz

Hi ,
Thank you very much Adei,It is working for files which are not compatible with the browser(i.e .doc,.docx…etc).But when I download .xml,.html,.ftl….etc which are browser compatible are opening in the same page those are not getting downloaded.

Anyway Thanks a lot Adei

Check the wiki http://wiki.alfresco.com/wiki/URL_Addressability

if you use

http://127.0.0.1:8080/alfresco/d/a/workspace/SpacesStore/9e4a359f-3efc-4f0b-b6c2-bb78b98504ed/myfile.pdf?ticket=TICKET_1395001412eca3bf3bce84c349c7deb6c2fddc99‍

then it's attaching the file in your browser and not trying to open it

. Be aware use ticket as param instead of alf_ticket!

Hi All,
Am currently working on Alfresco 4.0 share. I have few custom content types created in share.
I Created a folder ,applied versionable rule to it and created few custom content types and Out of the box content types(i.e HTML,Plain Text) inside that folder.I edited a content and saved it.,Since I applied versionable rule there, I can see the previous versions of it..And I want to download the previous version of a content.

Now I want to download these files,am able to download out of box content types but unable to download custom content types.Am getting some Webscript error. The download functionality is out of box one,I don't have any other java/Webscript written for this.

In my share-config-custom.xml these are the content types added.I added node and model types for these.

<create-content>
<content id="plain-text" mimetype="text/plain" label="HelpText" itemid="sk:HelpText" icon="text"/>
<content id="plain-text" mimetype="text/plain" label="ContextualText" itemid="sk:ContextualText" icon="text"/>
</create-content>

Am able to create custom content types properly. But unable to download them.Am getting the following error.

<———- ———————————— error starts here————————————————————>

One more thing what I observed is, when I am taking previous versions noderef and running that in nodebrowser I am finding cm:content property as null for alfresco model(i.e {http://www.alfresco.org/model/content/1.0}content = null), but for my custom model(i.e sk:content) am seeing content in node browser.when I revert the previous version to my current, its replacing my current version and am able to see the content there..!!!!!

Can someone help me to sort it out…???? It will be a great help..! Thank you,

amandaluniz_z

Hi,

you can append another HTTP query parameter to that webscript that forces the download of the file (a=true or a=false). This parameter defines whether you want the file to be attached or not.

Try with it and let me know.

Adei

Hi Adei,
Thanks for the reply,
Am very new to alfresco, can you tell/show how to add it in content.get.desc.xml..?

Is it what you were telling..?
<arg>
<shortname>attach</shortname>
<description>if true, force download of contentas attachment</description>
<default>true</default>
</arg>

I added this, value as true, but still getting the same error.

And how to add onemore option in the <arg> tag, like in below property ..,
<arg>
<shortname>property</shortname>
<description>the name of the content property to retrieve content from</description>
<default>cm:content</default>
</arg>

Default value is cm:content which is alfresco out of box, I have my custom content model as sk:content., should I add it there as ,<value>sk:content</value>? If yes is this the <value> tag used for it..?

can you Please help to fix it..?
Thanks ,

Regards,
Saina
