I am writing an MVC 3 application that needs to allow the user to directly upload a file to S3. I also need to show a progress bar. All of the examples I have seen are PHP or Ruby-on-Rails related. Has anyone managed to upload a file to S3 directly (from client browser) using MVC?
So, after a morning of smashing my head into my keyboard, the following snippet of code works (with the obvious credentials removed):
using (AmazonS3 client = Amazon.AWSClientFactory.CreateAmazonS3Client("Access_Key",
"Secret_Key"))
{
PutObjectRequest request = new PutObjectRequest();
request.WithBucketName("BUCKET-NAME")
.WithCannedACL(S3CannedACL.PublicRead)
.WithKey("myDirectory/" +
HttpContext.Current.Server.UrlEncode(fileBase.FileName))
.InputStream = fileBase.InputStream;
S3Response response = client.PutObject(request);
}

Using Python and the adal and requests packages I'm attempting to use the MS graph API to find files on sharepoint (when providing a sharepoint site name, folder name where the file is expected to be, and name of file.
Using various calls I can manage to do the following
Get an authentication token (using user auth to an app which has full permission to use users credentials and do all read/write on files being accessed)
establish a valid session
search sites and obtain details on my current site
microsoft_info = SESSION.get('https://graph.microsoft.com/v1.0/sites?search=nameOfSite')
Obtain drive information associated with the site
for site in microsoft_info['value']:
if site['displayName'] == siteDisplayNameInput:
siteId = site['id']
drives = SESSION.get("https://graph.microsoft.com/v1.0/sites/"+siteId+"/drives")
drives = drives.json()
Obtain file information from drive of interest
for drive in drives['value']:
if(drive['name']) == folderNameInput:
driveId = drive['id']
files = SESSION.get("https://graph.microsoft.com/v1.0/drives/" + driveId +"/root/search(q='')")
files = files.json()
And then at point 6 everything falls apart and I get 404 errors returned saying that resource is not found - despite using the identifiers provided by the API which are clearly indicating the presence of a resource.
if file['name'] == 'Pipeline Pilot Forms.pptx':
print("List of properties on file")
for x in file:
print(x+" "+str(file[x]))
fileId = file['id']
print(fileId)
callToDLFile = SESSION.get("https://graph.microsoft.com/v1.0/drives/"+driveId+"/items/"+fileId+"/content"
appears to be the code that should work for this (indentation appears to have failed copying things into this, but it is all good) but it returns 404 errors - any help would be greatly appreciated on this, I don't see (in a reasonably lengthy search) anything which matches this issue exactly out there.
I created a configuration file (Simple Text File) on my Google Drive and now I would like to read it from my Chrome Packaged Dart Application. But I'm not able to get more information of the file than it's name, size etc.
For accessing Google Drive I use the google_drive_v2_api.
Any suggestion on how to get the contents of my configuration file would be great! Thanks!
I just did some test in my own chrome app, uploading and downloading a simple file:
chrome.identity.getAuthToken(new chrome.TokenDetails(interactive: true ))
.then((token){
OAuth2 auth = new SimpleOAuth2(token);
var drive = new gdrive.Drive(auth)..makeAuthRequests=true;
drive.files.insert({},content:window.btoa('hello drive!')).then((sentMeta){
print("File sent! Now retrieving...");
drive.files.get(sentMeta.id).then((repliedMeta){
HttpRequest request = new HttpRequest()..open('GET', repliedMeta.downloadUrl)
..onLoad.listen((r)=>print('here is the result:'+r.target.responseText));
auth.authenticate(request).then((oAuthReq)=>oAuthReq.send());
});
});
});
It works, but the HttpRequest to get content back seems heavy...
But i really recommend you to a take look to chrome.storage.sync if your config file size is < to 4ko... If not, you could also use the chrome SyncFileSystem API... They are both easier to use, and SyncFileSystem use Drive as backend.
This page on downloading files talks through the process for getting the contents of a file.
I'm working on a SharePoint mobile solution where I'm using the web services exposed in server/_vti_bin/sitedata.asmx, server/_vti_bin/Lists.asmx and server/_vti_bin/copy.asmx.
I'm able to successfully fetch the list of sites, document libraries and files using the services defined in server/_vti_bin/sitedata.asmx.
Now I'm actually trying to upload an image file from Photo Albums available in iOS to SharePoint. For this, I tried using CopyIntoItems web service, where in I'm getting the following error response.
<CopyResult ErrorCode="DestinationInvalid" ErrorMessage="The Copy web service method must be called on the same domain that contains the destination url." DestinationUrl="http://xxxxserveripxxxxxx/Shared Documents/image1.png"/>
But came to know that this service is used only if the file to be uploaded is also from the same source(i.e., from sharepoint).
Is there any other way to upload a file available in iPhone to SharePoint.
Also tired addAttachment service defiend in server/_vti_bin/Lists.asmx but I'm unable to identify the input parameters which requires list name and list Item ID.
I'm trying to upload a file to Shared Documents, so I've List Name value which is the one in curly braces of Shared Documents but now what should be the List Item Id value?
These are the details I've with regard to "Shared Documents" document library.
{
AllowAnonymousAccess = false;
AnonymousViewListItems = false;
BaseTemplate = DocumentLibrary;
BaseType = DocumentLibrary;
DefaultViewUrl = "/Shared Documents/Forms/AllItems.aspx";
Description = "Share a document with the team by adding it to this document library.";
InheritedSecurity = true;
InternalName = "{425F837A-F110-4876-98DE-C92902446935}";
LastModified = "2013-07-26 20:09:58Z";
ReadSecurity = 1;
Title = "Shared Documents";
},
So, I'm using the using InternalName value for listName tag.
What should be the value of listItemID?
Am I going in the right way or is there any other approach to upload a local file from mobile to SharePoint?
Thanks

Are you actually calling a URL or are you using the IP (you x'ed it out and said server IP)? If you don't have Alternate Access Mappings defined for the IP, uploads will fail but the GET requests will generally work ok.
I am trying to get the right redirection URL for my sharepoint documents which then I can use to open documents in WebView of iOS. Currently I am giving the absolute URL for the document where the doc is rendered inside WebView as PDF(Image/Readonly). Whereas I want to redirect to office webapp. Now my issue is I dont know if the URL for office web app is something which I can construct like appending /_layouts/15/WopiFrame.aspx?sourcedoc= or is the URL custom based on installations and we need to call some Sharepoint API which will let us know what is the base URL for Wopi service.
Currently I am passing URL like - https://.sharepoint.com/Shared%20Documents/demo/demo.docx
Whereas I want to pass URL like - https://.sharepoint.com/_layouts/15/WopiFrame.aspx?sourcedoc=/Shared%20Documents/demo/demo.docx
Looking forward for help.
Thanks in advance,
Vishwesh
File f = clientContext.Web.GetFileByServerRelativeUrl("/sites/ /Shared%20Documents/Title.docx");
clientContext.Load(f);
clientContext.ExecuteQuery();
ClientResult<String> result = f.ListItemAllFields.GetWOPIFrameUrl(SPWOPIFrameAction.Edit);
clientContext.Load(f.ListItemAllFields);
clientContext.ExecuteQuery();
result.Value contains a URL, something like this:
http://sharep.xxx:8080/sites/zxxx/_layouts/15/WopiFrame.aspx?sourcedoc=%2Fsites%2Fzxxx%2FShared%20Documents%2FTitle%2Edocx&action=edit
Also you can extract the extract Office Web Apps URL from the above page, if you don't want to hit the sharepoint at all.
using Microsoft.SharePoint.Client;
using Microsoft.SharePoint.Client.Utilities;
// Assume we have these variables:
// ctx: A valid client context
// serverRelativeUrl: the URL of the document
File f = ctx.Web.GetFileByServerRelativeUrl (serverRelativeUrl);
result = f.ListItemAllFields.GetWOPIFrameUrl(SPWOPIFrameAction.Edit);
ctx.Load(f.ListItemAllFields);
ctx.ExecuteQuery();
This builds on the answer from #thebitlic which was the silver bullet for sure! However he or she is doing two calls to the server. Through the wonders of CSOM batching, it's possible to do it in one round trip, and no need to bring back the File object at all.
I have a need to store files on Amazon AWS S3, but in order to isolate the user from the AWS authentication I want to go via an ASP page on my site, which the user will be logged into. So:
The application sends the file using the Delphi Indy library TidHTTP.Put (FileStream) routine to the ASP page, along with some authentication stuff (mine, not AWS) on the querystring.
The ASP page checks the auth details and then if OK stores the file on S3 using my Amazon account.
Problem I have is: how do I access the data coming in from the Indy PUT using JScript in the ASP page and pass it on to S3. I'm OK with AWS signing, etc, it's just the nuts and bolts of connecting the two bits (the incoming request and the outgoing AWS request) ...
TIA

A HTTP PUT will store the file at the given location in the HTTP header - it "requests that the enclosed entity be stored under the supplied Request-URI".
The disadvantage with the PUT method is that if you are on a shared hosting environment it may not be available to you.
So if the web server supports PUT, the file should be available at the given location in the the (virtual) file system. The PUT request will be handled by the server and not ASP:
In the case of PUT, the web server
handles the request itself: there is
no room for a CGI or ASP application
to step in.
The only way for your application to
capture a PUT is to operate on the
low-level, ISAPI filter level
http://www.15seconds.com/issue/981120.htm
Are you sure you need PUT and can not use a POST, which will send the file to a URL where your ASP script can read it from the request stream?
OK, Ive got a bit further with this. Code at the ASP end is:
var PostedDataSize = Request.TotalBytes ;
var PostedData = Request.BinaryRead (PostedDataSize) ;
var PostedDataStream = Server.CreateObject ("ADODB.Stream") ;
PostedDataStream.Open ;
PostedDataStream.Type = 1 ; // binary
PostedDataStream.Write (PostedData) ;
Response.Write ("PostedDataStream.Size = " + PostedDataStream.Size + "<br>") ;
var XML = AmazonAWSPUTRequest (BucketName, AWSDestinationFileID, PostedDataStream) ;
.....
function AmazonAWSPUTRequest (Bucket, Filename, InputStream)
{
....
XMLHttp.open ("PUT", URL + FRequest, false) ;
XMLHttp.setRequestHeader (....
XMLHttp.setRequestHeader (....
...
Response.Write ("InputStream.Size = " + InputStream.Size + "<br>") ;
XMLHttp.send (InputStream) ;
So I use BinaryRead, write it to a binary stream. If I write out the size of the stream I get the size of the file I POST'ed from my application, so I reckon the data is in there somewhere. I then call a routine (with the stream as a parameter) which sets up the AWS authentication/signing and does a PUT.
The AWS call returns no errors and a file of the correct name is created in the right place, but it has a size of zero! InputStream.Size has a value the same as the stream parameter passed to the routine - i.e. the size of the original file.
Any ideas?
POSTSCRIPT. Found the problem. It's caught me a few times with streams, this one. When you write data to a stream, don't forget to reset the stream position back to zero before trying to read from the stream again. I.e. just before the line:
XMLHttp.send (InputStream) ;
I needed to add:
InputStream.Position = 0 ;
My thanks for the interest and suggestions.
