阿里云OSS文件上传

Sooner or later you'll have a ComfyUI image that a remote API needs to fetch - an image-translate service, a template renderer, an edit model that only accepts URLs. That's exactly the gap this node fills: it takes an IMAGE tensor (or local files) and uploads it to Alibaba Cloud OSS, then hands you back a URL the outside world can hit. For the API-heavy pack it lives in, it's the piece that closes the loop between "local pixels" and "cloud service".

The mechanism is plain oss2 - Alibaba's official Python SDK. You give it an endpoint, a domain, a bucket_name, and credentials; it turns your tensor into PNG bytes (JPEG or WEBP if your object key ends .jpg/.webp) and PUTs them to OSS. An object_key template with {timestamp}, {index}, and {name} placeholders keeps names unique and organized - default uploads/image_{timestamp}_{index}. use_timestamp appends a Unix timestamp to avoid collisions. batch_upload (default on) walks every image in a batch and uploads each as its own object.

The inputs you'll actually set

• bucket_name - required, your OSS bucket. Empty → error.
• access_key_id / access_key_secret - Alibaba Cloud AccessKey. The node also reads the env vars OSS_ACCESS_KEY, OSS_ACCESS_SECRET, OSS_BUCKET, and OSS_DOMAIN, so you can keep keys out of the workflow file.
• image - optional IMAGE input. Give it a tensor, get it uploaded.
• file_paths - optional, one local path per line, uploaded as-is with their extension.
• object_key - the key template (see above).
• make_public - sets a public-read ACL if you want anyone to fetch it without a signature.
• content_type - default image/png; for file uploads it's inferred from the extension instead.

Outputs

• oss_urls - JSON array of object keys.
• public_urls - JSON array of signed GET URLs (valid for an hour). These are what you hand to a downstream API node or a browser.
• upload_info - JSON summary: success counts, ETag, request ID, per-file results. Your debugging friend.

The one dependency that bites

The pack does not install oss2 for you. The source catches a missing import and just prints a warning in red and returns an error JSON. The moment you hit "oss2 库未安装", that's the fix:

pip install oss2

then restart ComfyUI. After that, the usual suspects: wrong region/endpoint mismatch, an AccessKey without bucket write permission, and a bucket name that doesn't exist. Oh, and public_urls are signed even when make_public is off - that's fine, just don't paste them into a workflow you're sharing after the hour expires.

Installing the pack

cd ComfyUI/custom_nodes
git clone https://github.com/jinchanz/ComfyUI-ADIC

Restart, or grab it via ComfyUI Manager under "ComfyUI-ADIC". No model downloads. You'll need a real Alibaba Cloud account with a bucket before this node does anything useful - it's pure cloud plumbing.
