uploading images with the nodebb-plugin-write-api

lostspace

I'm having trouble uploading images using the nodebb-write-api plugin

Here are the steps I've completed so far. The upload image nodebb-write-api example is at the bottom of this post.

Create NodeBB Instance

docker create --name myNodeBB --init --restart always -e url="http://192.168.0.41:4567" -p 4567:4567 -v nodebb-data:/var/lib/redis -v nodebb-files:/opt/nodebb/public/uploads -v nodebb-config:/etc/nodebb nilsramsperger/nodebb

Start NodeBB Instance

docker start myNodeBB

Install https://github.com/NodeBB/nodebb-plugin-write-api/

docker exec -it myNodeBB sh

download NodeBB write-api plugin

cd /opt/nodebb/node_modules

wget https://github.com/NodeBB/nodebb-plugin-write-api/archive/refs/heads/master.zip

unzip master.zip

NodeBB activate the nodebb-plugin-write-api

activate nodebb api write plugin

Create a master token with uid 0

master token uid 0

Stop/Start NodeBB Instance

docker stop myNodeBB

docker start myNodeBB

CREATE USER (WSL/Ubuntu)

Thank you

I'm also trying to validate my curl upload to a diagnostic http inspector url

http://httpbin.org/post

My local NodeBB endpoint I'm substituting to the http://httpbin.org/post endpoint to validate my curl commands
[http://localhost:4567/api/v3/util?_uid=1]

(http://localhost:4567/api/v3/util?_uid=1)

[email protected]:/mnt/c/Users/Terry/Downloads$ ls -l *.jpg
-rwxrwxrwx 1 terry terry 13810 Dec  4 19:10 boat.jpg
-rwxrwxrwx 1 terry terry  4966 Dec  4 14:15 walrus.jpg

Some more examples I'm attempting

-X POST http://httpbin.org/post

curl \

-F '_uid=1' \
-F 'files[]=@/mnt/c/Users/Terry/Downloads/boat.jpg' \
-X POST http://httpbin.org/post

My Curl command's all return a not-found message

{"status":{"code":"not-found","message":"Invalid API call"},"response":{}}

I found more upload utils...I should have checked here first. This is exactly what I need.

The way I'm organizing my curl is "forbidden" to my instance to NodeBB. So, I must be making an incorrectly formed cURL.

I found this post very helpful it is exactly what I'm looking for Update category picture (via image upload) API not working

I was able to upload an empty image using the cURL from "Copy as cURL (bash)" in the Chrome developer tools to my WSL2/Ubuntu console.

The "Copy as cURL (bash)" in the Chrome Developer tools doesn't explicitly set the folder name parameters or set the file[] binary data array for easy substitution.

So, when I ran the "Copy as cURL (bash) from the Chrome Developer tools it uploaded an "empty" image of 0kb correctly named.

curl 'http://localhost:4567/api/admin/upload/file' \

  --compressed

How to get the "Copy as cURL (bash)

Output from the cURL command from the Chrome Developer Tools

[{"url":"/assets/uploads//test/walrus.jpg"}]

So, I need to replace what is in the --data-raw

--data-raw $'------WebKitFormBoundary1bBgU3aYIkSJ4VmP\r\nContent-Disposition: form-data; name="files[]"; filename="walrus.jpg"\r\nContent-Type: image/jpeg\r\n\r\n\r\n------WebKitFormBoundary1bBgU3aYIkSJ4VmP\r\nContent-Disposition: form-data; name="params"\r\n\r\n{"folder":"/test"}\r\n------WebKitFormBoundary1bBgU3aYIkSJ4VmP--\r\n' \

With something like:

-F 'name=params: {"folder":"/test"}' \
-F "files[1]=@/mnt/c/Users/Terry/Downloads/small.jpg" \

Thank you

Got it!

works!

removed:

"Content-Type": "multipart/form-data; boundary=----WebKitFormBoundarycWHrDFflR4bC1tZQ",

and replaced the --data-raw from the original with

--form "params={\"folder\":\"/test\"}" \
--form "files[]=@/mnt/c/Users/Terry/Downloads/small.jpg"

curl 'http://localhost:4567/api/admin/upload/file' \

This works!

I'm going to try to find more efficiencies in the above cURL upload command

Thank you

lostspace

"A" minimal cURL command to upload an image

curl 'http://localhost:4567/api/admin/upload/file' \
-H 'Cookie: express.sid=s%3A3aOlEybRIA-2ETDSLhzJbAAeFBbDqRSY.aqBLldxcKQCncS7C4NDqd7tD9lsXLWdbw2wA4P8HwoE' \
-H 'x-csrf-token: aUs0HZSZ-EBNli65aMwZw-vKpHAdZAz02X7k' \
--form "params={\"folder\":\"/test\"}" \
--form "files[]=@/mnt/c/Users/Terry/Downloads/small.jpg"

Thank you

@lostspace just so you know you're not blasting posts into a black hole that nobody ever sees....

Thanks for the information you've provided. The API can be difficult to understand and work with, and the examples you've posted will undoubtedly help others in the same journey.
