cf+b2搭建图床

说明

cloudflare+b2搭建图床算是比较经典的一种白嫖图床的方式了，另一种是github+jsdelivr，不过由于jsdelivr被墙了，导致我之前博客的图基本都挂了，急忙更换cdn。因此最近在鼓捣标题的方法，看了一圈大佬们的方法，核心操作都是b2上建一个公开的bucket，然后用cf反代+隐藏bucket名。我实在太菜了，第二步搞了一晚上..

这种方法的傻瓜式教学为参考链接

经过github一番搜索，找到了第二种更官方，个人认为更好的方法，简单总结为b2上建一个私有的bucket + app令牌 + 官方cf worker。

准备

一个b2私有bucket
cf账号和域名
nodejs+npm

配置wrangler

wrangler是cf官方的，用于在命令行配置worker等的工具，官方原话为

Wrangler is a command-line tool for building with Cloudflare developer products.

一开始我打算用ssh远程服务器登录wrangler，但新版wrangler改了token登陆的方式，按照新的方式一直登不上去，必须要打开本地浏览器，ssh哪来的浏览器..

因此只得在本地windows电脑上安装。首先安装nodejs和npm，此处略过

然后输入

npm i -g wrangler

登录cf

wrangler login

Untitled

按照提示打开链接，登录cf

然后下载官方的仓库https://github.com/backblaze-b2-samples/cloudflare-b2

命令行进入对应的目录，修改wrangler.toml

#这里填worker名
name = "b2"

workers_dev = true
compatibility_date = "2022-11-18"

main = "index.js"

# Don't put your application key in this file!
# You should set it as a secret in the Cloudflare dashboard or at the command line:
# echo "<your b2 application key>" | wrangler secret put B2_APPLICATION_KEY
[vars]
B2_APPLICATION_KEY_ID = "申请的app keyID"
B2_ENDPOINT = "s3.us-west-000.backblazeb2.com"
# Set BUCKET_NAME to:
#   "A Backblaze B2 bucket name" - direct all requests to the specified bucket
#   "$path" - use the initial segment in the incoming URL path as the bucket name
#           e.g. https://images.example.com/bucket-name/path/to/object.png
#   "$host" - use the initial subdomain in the hostname as the bucket name
#           e.g. https://bucket-name.images.example.com/path/to/object.png
BUCKET_NAME = "你的bucket名"
# Backblaze B2 buckets with public-read visibility do not allow anonymous clients
# to list the bucket’s objects. You can allow or deny this functionality in the
# Worker via ALLOW_LIST_BUCKET
ALLOW_LIST_BUCKET = "true"

#此处新增
B2_APPLICATION_KEY = "申请的app secret key"

注意官方建议在cf的网页面板添加B2_APPLICATION_KEY，但实测会出现以下错误
