I needed to export our Confluence instance, here was a super easy way to get all pages, and create a file for each page (named after the article) and the page's resulting HTML.

export-confluence-to-html.sh

#!/bin/bash
export CONFLUENCE_USERNAME="your_username"
export CONFLUENCE_PASSWORD="your_password"

function get_page_html()
{
mkdir ~/confluence;
result=$(curl --request GET \
  --url "https://ventureapp.atlassian.net/wiki/rest/api/content/$1/?expand=body.export_view" \
  --user $CONFLUENCE_USERNAME:$CONFLUENCE_PASSWORD \
  --header 'Accept: application/json' \
  --header 'Cache-Control: no-cache' \
  --header 'Content-Type: application/json');

title=$(echo $result | jq '.title' | sed 's/\"//g' | sed 's/[][*]\|[[:space:]]//g' | sed "s/ /-/g");
file=~/confluence/$title.html
touch $file;

body=$(echo $result | jq '.body.export_view.value' | sed 's/^.\(.*\).$/\1/');
echo $body > $file;
}

function listpages()
{
limit=500;
loops=1;

for ((i=0;i<=$loops;i++)); do
start=$( expr $i '*' "$limit" )
results=$(curl --request GET \
  --url "https://ventureapp.atlassian.net/wiki/rest/api/content/?limit=$limit&start=$start" \
  --user $CONFLUENCE_USERNAME:$CONFLUENCE_PASSWORD \
  --header 'Accept: application/json' \
  --header 'Cache-Control: no-cache' \
  --header 'Content-Type: application/json');
ID=$results | jq '.results[] | .id' | sed 's/\"//g' >> ~/repos/hqo/json.txt;
get_page_html $ID;
done
}

listpages();
