How do I download binary files of a GitHub release?

问题

I have a repo with binary files in it that I need.

I can

git checkout tags/thetagoftherelease

which seems to checkout the correct tag, but does not pull down the binary files. How can I pull down the binary files that were added to the release (the green boxes on the release)?

Added picture of binary files in a release.

I've tried for days trying to find the proper answer to this, and finally I figured out how to do this via the curl command. It's a 3-step process.

First, to get a list of the assets for the latest release:

curl -H "Authorization: token YOURGITHUBTOKEN" \
    https://api.github.com/repos/NAME/REPO/releases/latest

Then in the JSON, look up the url of the asset you want. For example it would look like:

"url": "https://api.github.com/repos/NAME/REPO/releases/assets/1275759"

Then you pass this to another curl command to retrieve the actual URL, which is actually a link to an Amazon S3 file.

curl -H "Authorization: token YOURGITHUBTOKEN" \
     -H "Accept:application/octet-stream" \
     -i https://api.github.com/repos/NAME/REPO/releases/assets/1275759

The URL will be in the "location" field of the HTTP response, and then use curl to get the file like this:

curl "https://github-cloud.s3.amazonaws.com...." -i -o FILENAME

Binary release assets exist outside of Git, and cannot be managed using the standard tools.

They should be available via GitHub's API, though.

List the repository's release assets:

GET /repos/:owner/:repo/releases/:id/assets

This will send back a JSON document listing the release assets for the repository, e.g.

[
  {
    "url": "https://api.github.com/repos/octocat/Hello-World/releases/assets/1",
    "browser_download_url": "https://github.com/octocat/Hello-World/releases/download/v1.0.0/example.zip",
    "id": 1,
    "name": "example.zip",
    "label": "short description",
    "state": "uploaded",
    "content_type": "application/zip",
    "size": 1024,
    "download_count": 42,
    "created_at": "2013-02-27T19:35:32Z",
    "updated_at": "2013-02-27T19:35:32Z",
    "uploader": {
      "login": "octocat",
      ...
    }
  }
]

Retrieve the assts from the release you want, as defined by its id from above:
```
GET /repos/:owner/:repo/releases/assets/:id
```
If you want to download the asset's binary content, pass a media type of "application/octet-stream". The API will either redirect the client to the location, or stream it directly if possible. API clients should handle both a 200 or 302 response.

As documented, these requests are all relative to https://api.github.com.

For Ansible, you can use this tasklist (same steps as @ted):

- name: Get latest version
  uri:
    url: "https://api.github.com/repos/{{github_user}}/{{github_repo}}/releases/latest"
    return_content: yes
    headers:
      Authorization: "token {{ vault_github_deploying_token }}"
  register: github_response

- set_fact:
    binary_asset_url: "{{  github_response.json.assets|json_query(query) }}"
  vars:
    query: "[?name=='{{your_github_binary_filename}}'].url | [0]"   

- name: Get Binary asset's location
  uri:
    url: "{{ binary_asset_url }}"
    return_content: no
    follow_redirects: none
    status_code: 302
    headers:
      Authorization: "token {{ vault_github_deploying_token }}"
      Accept: "application/octet-stream"
  register: assets

- name: Download binary
  get_url:
    url: "{{ assets.location }}"
    dest: "/tmp/{{ your_github_binary_filename }}"
    mode: 0755

Note that wget cat get it directly by following download link as a browser do.

Rewrite $URL as you need. My convention is to upload with a suffix for binary version.

A sample script:

#!/bin/bash
#
# You can fetch some binary directly from release on github
#
# We encourage to build your own version from source.
#

GIT_USER=me
GIT_PROJECT=project_name
BASE_URL=https://github.com/$GIT_USER/$GIT_PROJECT/releases/download
RELEASE=v0.6.3-alpha1
BINARY=bin_file_on_release

if [[ -e $BINARY ]]
then
  echo "file in the way: '$BINARY' remove it."
  exit 1
fi

if [[ $(getconf LONG_BIT) == "64" ]]
then
    echo "I'm 64-bits"
    URL="$BASE_URL/$RELEASE/$BINARY"
else
    echo "I'm 32-bits"
    URL="$BASE_URL/$RELEASE/${BINARY}-32bits"
fi

set -e
echo "Fetching from: $URL"
wget -q -O $BINARY "$URL"
file $BINARY
chmod a+x $BINARY
