Renewing Embedded Discord Links

I'm currently trying to archive all my own posts, which includes downloading all their embedded files and attachments. I fetch all the channel messages and from what I've done it seems like direct attachments do work; but embeds like a copy/pasted cdn.discordapp.com/attachments/.../.../file.jpg file will not renew. More specifically a link like https://media.discordapp.net/attachments/987627219973210124/1127972112628453449/snapchat.gif which is from the gif selector does show up in my client, but not to my bot because it lacks the signature queries. Is there a way to get them to renew so they can be downloaded?

the gif in question when pasted in a message: https://media.discordapp.net/attachments/987627219973210124/1127972112628453449/snapchat.gif

the original link is just: https://media.discordapp.net/attachments/987627219973210124/1127972112628453449/snapchat.gif discord populates my client with the signatures:

Refetch the message Consider storing your pictures elsewhere. This is intentional design by Discord

SukadiaOP•2mo ago

you might need to clarify, they are already fetched are they not? it's because it's a content link that it won't give me the signature that renews it and yes yes the point is to grab them to archive them on my own database edited in a clarifier the messages are fetched from the channel, so i already have their objects and whatnot

Is the link not in the content?

SukadiaOP•2mo ago

yea the link is in the content, so i'm trying to get it from message.embeds as opposed to message.attachments

Inky•2mo ago

What path did you use to extract the image from the embed?

SukadiaOP•2mo ago

embed.url and embed.data.url which seem to be the same here's the code, it fails at !res.ok because content doesn't exist:

        const embedArrays = Array.from(message.embeds.entries())
        for (let embedArray of embedArrays) {
          const embed = embedArray[1]
          const url = embed.data.url
          if (!url) continue
          const res = await fetch(url, {method: "HEAD"})
          if (!res.ok) {
            console.log(`F - Failed to check embed: ${url}`)
            continue
          }
          const contentLength = res.headers.get("Content-Length")
          if (!contentLength) {
            console.log(`F - URL had no content length: ${url}`)
            continue
          }
          const bytes = parseInt(contentLength)
          console.log(`S - ${bytes} ${url} `)
          totalEmbedBytes += bytes
        }

        const embedArrays = Array.from(message.embeds.entries())
        for (let embedArray of embedArrays) {
          const embed = embedArray[1]
          const url = embed.data.url
          if (!url) continue
          const res = await fetch(url, {method: "HEAD"})
          if (!res.ok) {
            console.log(`F - Failed to check embed: ${url}`)
            continue
          }
          const contentLength = res.headers.get("Content-Length")
          if (!contentLength) {
            console.log(`F - URL had no content length: ${url}`)
            continue
          }
          const bytes = parseInt(contentLength)
          console.log(`S - ${bytes} ${url} `)
          totalEmbedBytes += bytes
        }

Is it not in the embed.image.url? I don’t remember how url embeds are structured

SukadiaOP•2mo ago

embed.image.url returns an empty string all the time, even for images that work. embed.url seems to only have the link. maybe it'd be populated if it was bot embeds or something still looking for a solution, i'm thinking it isn't possible. i attempted to attach the URL as an attachment in a new temp message to get it refreshed but that doesn't work. it seems like you can only get the CDN to renew it if it's a direct attachment, not a link (even though the actual client does renew it)

İspik•2mo ago

https://github.com/Sapphire-Discord-Bot/images Sapphire has come up with a solution like this, you could check it out

SukadiaOP•2mo ago

gotcha, so i'm just gonna drop it as "not possible" since the links are from other servers. i'll have to save the message links and download them manually from my client
