I have followed all instructions here: Retrieving media | Docs | Twitter Developer Platform

However The OAuth Get response is always a HTTP 302 - redirect.
I have attempted to GET the 302-location, but I still get same 302 response.

I have attempted to setup an <img> with src similar to the example, but the response body is empty and status is till 302.

Please can anyone provide clarity on this issue.

Thanks.

What library/ language are you coding in? Redirects should be followed to the actual content but sometimes the library needs some extra parameter or something to actually get the file contents

Thanks for the reply!.

I’m coding this in Elixir, I have a full view of the HTTP response stream.

I can see all the headers returned and the status codes.

Does this help? HTTPoison — HTTPoison v1.8.2 I don’t know Elixir so I’ve no idea if this is what you’re using but this library seems to be able to follow redirects

#5

I’m able to follow the redirects, by sending a second request once i see a HTTP302, i’m using Tesla Library, but i will see if using auto-redirect helps.

no luck, I get a redirect cascade, and eventually a redirect overflow.

Please can you point me to an implementation of Twitters DM media download that actually works?

I can use such as a guide.

Hi , Good Morning, Please do you know of any open-source implementation for this?

I have left a complaint @twitter documentation but I have seen not mention of 302 issues or a response

It still seems like a library or authentication issue to me - because i can successfully get the image like this in python:

from requests_oauthlib import OAuth1Session
import shutil

api = OAuth1Session(
                client_key="...",
                client_secret="...",
                resource_owner_key="...-...",
                resource_owner_secret="...",
            )

response = api.get("https://ton.twitter.com/i/ton/data/dm/.../.../....jpg", stream=True)

print(response.status_code)

with open("image.jpg", "wb") as f:
    shutil.copyfileobj(response.raw, f)

Not sure how helpful this is, but this makes an oAuth1 authenticated GET to a Media URL from a DM, and saves it as a file. There are no redirects in this request, the status is 200.

Now to complete the Retrieving media | Docs | Twitter Developer Platform guide, you would implement an endpoint on your backend, that will take an image URL, authenticate it with oAuth1, and serve it like this:

<img src="fetch_dm_image?url=https://ton.twitter.com/i/ton/data/dm/....jpg">

for example, in python:

Need these dependencies:

pip install fastapi uvicorn requests requests-oauthlib

This would be fetch_image_api.py :

from fastapi import FastAPI
from fastapi.responses import StreamingResponse
from requests_oauthlib import OAuth1Session

app = FastAPI()

@app.get("/fetch_dm_image")
def fetch_dm_image(url: str):

    api = OAuth1Session(
        client_key="...",
        client_secret="...",
        resource_owner_key="...-...",
        resource_owner_secret="...",
    )

    response = api.get(
        url,
        stream=True,
    )

    print(url)
    print(response.status_code)

    return StreamingResponse(response.raw, media_type="image/jpeg")

Run it

uvicorn fetch_image_api:app --reload

And now this should work:

http://127.0.0.1:8000/fetch_dm_image?url=https://ton.twitter.com/i/ton/data/dm/.../.../....jpg

and so will this on a page:

<img src="fetch_dm_image?url=https://ton.twitter.com/i/ton/data/dm/....jpg">

I got similar directions here: DM Media download results in redirection loop - #4 by yfilyk

I will review the library and see

Maybe the library I’m using is the problem, but i’ll keep investigating
