New Post: Set Bucket Name based on Querystring Value

gushal — Thu, 29 Oct 2009 01:25:11 GMT

Hi,

Trying to set the value of a bucket to a QueryString value being passed to the uploader page. C# novice, so help appreciated.

New Post: can I set Content-type on upload using Direct Amazon Uploader?

vladb — Thu, 22 Oct 2009 16:27:24 GMT

Well then you just need different kind of component, not file uploader but Amazon browser.

You cannot change upload headers due to Amazon restriction. More on that:

http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/flash/net/FileReference.html#download()

The text in red sais: The requestHeaders property of the URLRequest object is ignored; custom HTTP request headers are not supported in uploads or downloads.

http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/flash/net/FileReference.html#download()

The text in red sais: "The requestHeaders property of the URLRequest object is ignored; custom HTTP request headers are not supported in uploads or downloads. "

Can I set the Content-Type header on the Direct Amazon Uploader? I want to force all files to download instead of displaying on the browser when clicked on the Amazon file link.

Thanks,

New Post: Onfilenamedetermining , can not read url parameters, viewstate or other page data?

paulmurp — Thu, 22 Oct 2009 14:22:02 GMT

I had real trouble with the State variables. Never got them to work so just made the following change in the source:

 	protected string _pageUrl;

        public string PageUrl
        {
            get
            {
                return this.ComposePageUrl(HttpContext.Current.Request.Url.AbsoluteUri.Substring(0,
                            HttpContext.Current.Request.Url.AbsoluteUri.Length - HttpContext.Current.Request.Url.Query.Length));

                //return this.ComposePageUrl(HttpContext.Current.Request.Url.AbsoluteUri.Substring(0,
                //            HttpContext.Current.Request.Url.AbsoluteUri.Length));
            }
            set
            {
                _pageUrl = value;
            }
        }

This allowed me to set the full PageUrl specifically (and thus pass it any extra querystring parameters). Then I updated the ComposePageUrl method to include a check if this variable has been set:

private string ComposePageUrl(string pageUrl)
        {
            if (!String.IsNullOrEmpty(_pageUrl))
                pageUrl = _pageUrl;

...

This may not be the tidiest or smartest way to do this, but it got me through... hope it helps!

protected string page_url;

public string PageUrl

{

get

{

return this.ComposePageUrl(HttpContext.Current.Request.Url.AbsoluteUri.Substring(0,

HttpContext.Current.Request.Url.AbsoluteUri.Length - HttpContext.Current.Request.Url.Query.Length));

//return this.ComposePageUrl(HttpContext.Current.Request.Url.AbsoluteUri.Substring(0,

// HttpContext.Current.Request.Url.AbsoluteUri.Length));

}

set

{

// return this.ComposePageUrl(HttpContext.Current.Request.Url.AbsoluteUri.Substring(0,

// HttpContext.Current.Request.Url.AbsoluteUri.Length - HttpContext.Current.Request.Url.Query.Length));

page_url = value;

}

 protected string _pageUrl;

        public string PageUrl
        {
            get
            {
                return this.ComposePageUrl(HttpContext.Current.Request.Url.AbsoluteUri.Substring(0,
                            HttpContext.Current.Request.Url.AbsoluteUri.Length - HttpContext.Current.Request.Url.Query.Length));

                //return this.ComposePageUrl(HttpContext.Current.Request.Url.AbsoluteUri.Substring(0,
                //            HttpContext.Current.Request.Url.AbsoluteUri.Length));
            }
            set
            {
            //    return this.ComposePageUrl(HttpContext.Current.Request.Url.AbsoluteUri.Substring(0,
            //                HttpContext.Current.Request.Url.AbsoluteUri.Length - HttpContext.Current.Request.Url.Query.Length));
                _pageUrl = value;
            }
        }

When you have ajax call it happens on a different request by definition so you won't find any of those

New Post: Amazon DirectUploader Querystring Issues

vladb — Wed, 21 Oct 2009 01:00:37 GMT

Anything that is passed with the confirmation request is defined at

/js/DirectAmazonUploader.js function stateChange you can make that function to read from global varianble for example.

Then on the server side you jyst get it from this.Request.QueryString["WhateverIsYourKey"]

mattsweetland — Thu, 15 Oct 2009 00:27:22 GMT

I am using the Onfilenamedetermining event to change the name of the file. My goal is to rename the files based on ids given by my CMS. I have a contentblock that gets its id as a dynamic parameter from the url query string parameters url?id=X... I am trying to use this contentblock id to rename my file but can not access this, all I get is an empty string, what am I doing wrong?

ASPX code:

<fjx:fileuploader id="FileUploader1" allowedfiletypes="Flash Videos:*.flv;*.txt;*.xml;*.doc"
                    runat="server" issinglefilemode="True" transparentbackground="True">
    <Adapters>
        <fjx:DirectAmazonUploader OnFileNameDetermining="FileUploader1_FileNameDetermining"
        OnConfirmUpload="FileUploader1_ConfirmUpload" ConfirmUploadJsFunc="ConfirmUploadJsFunc"
            Path="videos"
            FileAccess="Private"
            AccessKey="WebConfig:AmazonAccessKey"
            SecretKey="WebConfig:AmazonSecretKey"
            BucketName="origotree" AllowPathDefinedByClient="False" />
    </Adapters>
</fjx:fileuploader>

VB.net code (each of these fail to get the id parameter...

Protected Sub FileUploader1_FileNameDetermining(ByVal sender As Object, ByVal e As com.flajaxian.FileNameDeterminingEventArgs)
        e.FileName = "test" & request.querystring("id") & ".txt"
        'e.FileName = "test" & viewstate("id") & ".txt"
        'e.FileName = "test" & content.id("id") & ".txt" ' this is done through a control specific to my cms... just showing that it does not work here
End Sub

New Post: emails and ACLs - not getting it

charrington — Wed, 14 Oct 2009 04:35:22 GMT

according to Amazon docs,

"You can grant access to buckets and objects within your Amazon S3 account to anyone with an Amazon Web Services account. Any users that you grant access will be able to access buckets and objects using their AWS Access Key IDs and Secret Access Keys."

And I see here:

http://flajaxian.com/flajaxian.com/docs/html/HowToUseAmazonUploader.htm

that you can specify an access control list. What I dont understand is where would a user do the "using their AWS Access Key IDs and Secret Access Keys" part. The HowTo example has the access and secrets hard-coded. Do I have to programmatically set the keys after getting them from the user? How is that secure? Some core piece of the usage of this control is missing from the documentation.

New Post: Direct uploader 403 error on files bigger than 10mb

quynhtran — Tue, 13 Oct 2009 16:15:57 GMT

Flajaxian,

Recently i started getting 403 error on any files bigger than 10mb. The upload time for a 13mb file takes less than a minute. All files under 10mb uploads fine. Previously, i was able to upload files that were bigger than 200mb. ACL is properly set to the folder and crossdomain.xml file. Have you run into this problem before? Is there anything else i need to check?

i checked the webconfig for execution limits as well:

New Post: Issue Using Direct Uploader with SSL and Load Balancer

ryantriggs — Tue, 06 Oct 2009 16:49:05 GMT

Hello,

I am running into trouble trying to upload a file on a load balanced environment over SSL. The AJAX request to the server (before it uploads the file to Amazon) is failing because the url is incorrect. The load balancer/SSL setup is complicated, but it basically causes the application to see the request https://my.website.com/ as http://my.website.com:81/. Thus, the rendered javascript is DirectAmazonUploader.set_url("http://my.website.com:81/..."), which contains an invalid URL (port 81 is not open publicly).

I understand I will probably have to modify the source to fix this problem. I just thought I'd throw this out there to see if anyone had encountered a similar problem.

Thanks,

--Ryan Triggs

New Post: onconfirmupload event not working

vladb — Mon, 05 Oct 2009 02:29:51 GMT

Well you can't expect an event on an ajax request to affect your main request unless you write some javascript.

I would recommend you google for some basic ajax tutorials in order to understand what is ajax and how it works. Even better would be to install Fiddler and to observe different request so to understand what is happening in each request.

For client side changes and how to update UI without refreshing the page refer to http://flajaxian.com/flajaxian.com/DirectAmazonUploader1.0Help.html#ConfirmUploadClientSide

New Post: Amazon DirectUploader Querystring Issues

bsantoro — Mon, 21 Sep 2009 12:31:55 GMT

Hi kbende. I'm glad that you posted on this since I'm running into the same issue on a project I am working on. It seems like when the amazon directuploader goes to upload the file, it causes a post to the same page but the page.ispostback is always set to false. To try to get around this I tried saving my important varibles using the FileUploader1.State.Add("MyKey", "MyValue"); and <%=FileUploader1.ClientID%>.setStateVariable("MyKey", "MyValue"); documented in the file uploader help but am not able to retrieve them. I too need to access these query string parameters on each page load. Is there something that I am missing also?

New Post: Amazon DirectUploader Querystring Issues

kbende — Sat, 19 Sep 2009 20:03:27 GMT

Been having an issue for a long time with losing the QueryString parameters when it initializes the the AJAX calls. On the page load, it checks for a querystring parameter and if it isnt there it redirects to another page. When you upload a file, flajaxian makes a request to the page you are on with different querystring parameters and my parameters are gone and then the file is never uploaded.

http://www.domain.com/homepage.aspx?qs=57

-------------------------

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim s As String
        s = Me.Request.QueryString("qs")

        If s = Nothing Then
            Response.Redirect("Error.aspx")
        End If

End Sub

-------------------------

<fjx:FileUploader ID="AmazonUploadFileUploader" runat="server" ForeColor="Black"
                        MaxFileSize="100MB" MaxFileSizeReachedMessage="Files must be smaller than {0} to upload."
                        MaxFileQueueSize="200MB" MaxFileQueueSizeReachedMessage="All the files can not be bigger than {0}."

                            SecretKey="WebConfig:AmazonSecretKey"
                            BucketName="mybucketname"
                            FileAccess="Private"
                            OnFileNameDetermining="AmazonUploadFileUploader_FileNameDetermining"
                            OnConfirmUpload="AmazonUploadFileUploader_ConfirmUpload"
                            ConfirmUploadJsFunc="ConfirmUploadJsFunc"
                            />
                    </Adapters>
                </fjx:FileUploader>

----------------------- The response I see from fiddler and then in the page load since ?qs= isn't in there, it gets redirected to error.aspx and the file is never uploaded

POST /mydomain/webpage.aspx?__ID=ControlClientID&&__T=DirAmz.Initial HTTP/1.1

You can see that the request removes my querystring and puts the __ID and __T variables in the url.

What can i do as a workaround for this? I need to pass these querystring parameters everytime on my pages.

Fixed the previous problem by modifying the as code to call this.initiateUpload(); instread of this._files.startUpload(); in startUpload

however now the problem is the brows button does not get disabled, this.setButtons(false, false, true); is being called explicitly.
