I have a web app build with pyramid. One of the endpoints /foo is connected to the method foo(request):
def foo(request):
file = request.POST['my_file'].file
...do stuff with file...
I then send a file to the endpoint using postman. The problem is, the file is opened as a BufferedRandom in binary mode, but I need to manipulate the file in text mode. Is it possible to do this?
Found my answer here: Not able to parse a .csv file uploaded using Flask
In my case I added
stream = io.StringIO(file.read().decode("utf8"), newline=None)
and was able to manipulate stream

I am trying to upload a file to the Shared Documents library of my SharePoint website. The files are of type PDF and HTML. I am running a Cold Fusion development environment and using CFHTTP commands to execute HTTP requests. I have been able push a POST command and a PUT command to the proper endpoints listed on this link below:
Link: https://learn.microsoft.com/en-us/graph/api/driveitem-createuploadsession?view=graph-rest-1.0#best-practices
I do not understand why but the first section that mentions the HTTP requests for creating an upload session is different than what was used in the example a little further. For my project, I am using the endpoint:
"/{variables.instance.microsoftGraphAPIURL}/drive/root:/{item-path}:/createUploadSession"
P.S. variables.instance.microsoftGraphAPIURL is a variable to a microsoft graph endpoint to our Sharepoint website
With better luck using PUT commands than POST commands for creating an Upload Session. I am able to receive an uploadURL, but the issue comes with trying to upload the file. For the file upload, I am trying to upload a file in the same directory with a file size of 114992 bytes. I keep getting "The Content-Range header length does not match the provided number of bytes." whenever I run my Put command to upload the file.
Thus, my Content-Range is "bytes 0-114991/114992" and my Content-Length is "114992". For the image below, I replaced the file with a pdf, but the original file was an HTML page at 114992 bytes. I want to use a resumable upload session to have one function for uploading image, HTML, and PDF files.
If anyone could tell me if there is an issue with my content headers or my upload session http request or anything else that is causing my issue, that would be amazing! Thank you.
Problem is i have hosted at pythonanywhere using django.Video is downloaded at pythonanywhere server and user/client system too.Thats why i used os. remove(path).After downloading it removes from server.
Is there any ways files donot write on pyhtonanywhere server. so that i donot use os.remove(path).
How to restrict to write at pythonanywhere server. Only to download at user system.
def fb_download(request):
link = request.GET.get('url')
html= requests.get(link)
try:
url= re.search('hd_src:"(.+?)"',html.text)[1]
except:
url= re.search('sd_src:"(.+?)"',html.text)[1]
path=wget.download(url, 'Video.mp4')
response=FileResponse(open(path, 'rb'), as_attachment=True)
os.remove(path)
return response
If I understand correctly, you're trying to get a request from a browser, which contains a URL. You then access the page at that URL and extract a further URL from it, and then you want to present the contents of that second URL -- a video -- to the browser.
The way you are doing that is to download the file to the server, and then to serve that up as a file attachment to the browser.
If you do it that way, then there is no way to avoid writing the file on the server; indeed, the way you are doing it right now might have problems because you are deleting the file before you've returned the response to the browser, so there may (depending on how the file deletion is processed and whether the FileResponse caches the file's contents) be cases where there is no file to send back to the browser.
But an alternative way to do it that might work would be to send a redirect response to the URL -- the one in your variable url -- like this, without downloading it at all:
def fb_download(request):
link = request.GET.get('url')
html= requests.get(link)
try:
url= re.search('hd_src:"(.+?)"',html.text)[1]
except:
url= re.search('sd_src:"(.+?)"',html.text)[1]
return redirect(url)
By doing that, the download happens on the browser instead of on the server.
I don’t understand javascript really good,
But i think if you download the file to the server
And then you can download the file to the use using JS
And i think you can use
I have been struggling with Jenkins lately, and I'm stuck because I wanna send some parameters through HTTP Post, and I know how to do it, but the thing is that I am saving a Http request response to a file in my workspace, and then I want to use that file, read it and send the text I saved previously to a new HTTP Request, does anyone have any idea how can I achieve this?
Thanks in advance!!!
Install copy artifacts from another project plugin ( copy artifacts) add in build steps store the file in your workspace then you can run a shell script to read the desired content from that file .
if curl would work, that would be a simple way to send a file's contents as your POST body. see this answer.
Jenkins can work with Jmeter and Jmeter is great tool for handling request and response see tutorial
I am trying to upload a file using a form with Dajax.
I use serializeObject to serialize data with JavaScript. However, an input with a file type is not serialized before it sends to the server. Is there any way to upload a file using Dajax?
this is my problem: I have some pdf files on a server, my Django web-application
is hosted on another server (not the same of the pdf files).
On my appplication i know the pdf files link on the other server. I want to download that pdf files through my application without read them on web server application.
I try to explane. If i click on download link, my browser shows the pdf into his internal pdf viewer. I don't want this, i want that on click on a button the user will download the file without open it on internal browser.
I looked here: http://docs.djangoproject.com/en/dev/ref/request-response/#telling-the-browser-to-treat-the-response-as-a-file-attachment
but this is not a good way for me, cause it requires that I read the file inside my web-application and after return it to the user.
Is it possible??
Hmm, sounds like the wrong tool for the job. You can't really "redirect" and modify the response header, which means using django just to set the Content-Disposition header would require you to stream the file through django, then have django stream it to the client.
Let a lighter weight web server handle that. If you happen to be using nginx, here's an awesome solution that fits your scenario 99% (the 1% being it's rails setting the header that nginx is waiting for).
If all you want is to set the header and the file doesn't need django processing, it would be even easier to proxy!
If you are not using nginx, I would change the title to a web server specific question about proxying a file & setting headers.
I had a similar problem recently. I have solved it downloading the file to my server and then writing it to the HttpResponse
Here is my code:
import requests
from wsgiref.util import FileWrapper
from django.http import Http404, HttpResponse
def startDownload():
url, filename, ext = someFancyLogic()
request = requests.get(url, stream=True)
# Was the request OK?
if request.status_code != requests.codes.ok:
return HttpResponse(status=400)
wrapper = FileWrapper(request.raw)
content_type = request.headers['content-type']
content_len = request.headers['content-length']
response = HttpResponse(wrapper, content_type=content_type)
response['Content-Length'] = content_len
response['Content-Disposition']
= "attachment; filename={0}.{1}".format(filename, ext)
return response
