I am new to Parse Server (implementing it on Heroku and locally).
I have a basic question, when I upload a file using the ParseFile class, it provides me a URL and a fileobject. Where is this File being stored?
Is it being stored physically on a file system? Or in Mongodb?
Thank you!
I found a collection in Mongodb named fs.files. The files I uploaded were located there. I assume the Parse URL is generated as a redirect.

I'm the company's file server
Get the file as byte[] through the image path and authentication key.
(This server is not accessible to me.)
What I want to do is, when the user downloads the selected files, I want to compress these files and provide them as a compressed file.
Since the company's file server does not have a download API for multiple files, I think I need to request as many APIs as the number of file lists with a for statement in my service API.
In other words, it seems that we need to take a List<Byte[]> and compress this list.
Is there something wrong with my method?
And can I pass the result as json after compression? (I confirmed that the image file is passed as json.)
I want to move files my email to attachment to Azure BLOB using Power Automate. I am aware of the BLOB storage connection but I can't use it as I don't have the access key.
After surfing Google, I managed to find the below link. I need help on how to get the x-ms header and how to choose the folder inside the BLOB to upload the file into.
I lack all kind on experience in HTTP and Azure BLOB. :(
Please help.
Link: https://powerusers.microsoft.com/t5/Using-Flows/how-to-upload-to-blob-container-via-sas-url/m-p/125756#M3360
After reproducing from our end, Here is how we could able to save files in our blob from the HTTP connector.
We have used “x-ms-blob-type” as a header with a value of “BlockBlob”. Make sure you add the path to your storage account in URI in the below format.
https://<STORAGE ACCOUNT NAME>.blob.core.windows.net/<CONTAINER NAME>/<FILE NAME><SAS>
RESULT:
I have developed a small web application that runs a web server in golang.
Each user can login, view the list of their docs (previously uploaded) and click on an item to view an html page that shows some fields of the document plus an tag with a src attribute
The src attribute includes an url like "mydocuments/download/123-456-789.pdf"
On the server side I handle the URL ("mydocuments/download/*") via an http Handler
mymux.HandleFunc(pat.Get("/mydocuments/download/:docname"), DocDownloadHandler)
where:
I check that the user has the rights to view the document in the url
Then I create a fileserver that obviously re-maps the url to the real path of the folder where the files are stored on the filesystem of the server
fileServer := http.StripPrefix("/mydocs/download/",http.FileServer(http.Dir("/the-real-path-to-documents-folder/user-specific-folder/)))
and of course I serve the files
fileServer.ServeHTTP(w, r)
IMPORTANT: the directory where the documents are stored is not the static-files directory I sue for the website but a directory where all files end after being uploaded by users.
My QUESTION
As I am trying to convert the code for it to work also on Google Cloud, I am trying to change the code so that files are stored in a bucket (or, better in "sub-directories" -as they do not properly exist- of a bucket).
How can I modify the code so to map the real document url as available via the cloud storage bucket?
Can I still use the http.FileServer technique above (if so what should I use instead of http.Dir to map the bucket "sub-folder" path where the documents are stored)?
I hope I was enough clear to explain my issue...
I apologise in advance for any unclear point...
Some options are:
Give the user direct access to the resource using a signed URL.
Write code to proxy the request to GCS.
Use http.FS with an fs.FS backed by GCS.
It's possible that a fs.FS for GCS already exists, but you may need to write one.
You can use http.FileSystem since it is an interface and can be implemented however you like.
I am currently writing a Go web app using Revel.
My app needs to read the content of an XML file which is stored on the server. At the moment, I store this file in the "public" folder where some other resources (css, js...) lie.
I am using ioutil.ReadFile to read the content of this file. While this is working when the server is run from the main app folder itself, I cannot figure how to access the file when the server is run from another location (say by running "revel run myapp" from $GOPATH).
Is there any way to deal with this situation in revel?
is there a generic way to know the path of the "public" folder?
Any hint would be appreciated.
Thanks! :)
The base path of the application is stored and accessible through revel.BasePath.
The "public" folder can thus be accessed through revel.BasePath + "/public/<...>".
This BasePath value is used, for example, in Static.Serve.
I have a Sinatra application hosted on heroku and I'm trying to enable file uploading. I know heroku doesn't allow saving to the file system so I'm trying to save the image to MongoDB using GridFS directly. But I don’t know how.
Using the code below, I'm able to save to file system
base_dir = Dir.pwd + "/static/images/channels/"
File.open("#{base_dir}" + params['logo'][:filename], "w") do |f|
f.write(params['logo'][:tempfile].read)
end
How do I save the file directly to MongoDB without first saving it to the file system?
You can use the GridFS API to basically do what you're doing above, but write to MongoDB: http://api.mongodb.org/ruby/current/Mongo/GridFileSystem.html#open-instance_method.
I think you need to upload the file as binary data to a database.
You can use PaperClip to upload files and then store them as binary to MangoDB.
here this link might help you out:
If your files are actually less than 16 mb, please try using this Converter that changes the image of format jpeg / png to a format of saving to mongodb, and you can see this as an easy alternative for gridfs ,
please follow this github repo for more details
