准备
1.一个cloudflare账号 https://dash.cloudflare.com/
2.一个B2账号 https://www.backblaze.com/b2/cloud-storage.html
3.windows软件ShareX
步骤
1.注册B2账号,点击进入B2 Cloud Storage,点击Buckets创建一个BUcket,设为public,并上传一个图片,记录下下图要用的域名

2.点击App keys,添加一个新的key,bucket就选你刚创建的那个,记录下你的密钥,之后要在ShareX中用

3.打开cf,cname一下上图要记的域名,小云朵点亮

4.加一条页面缓存规则.

5.创建一个workers,粘贴下列代码,记得b2domain和bucket的值改成自己的
- 'use strict';
- const b2Domain = 'img.domain.com'; // configure this as per instructions above
- const b2Bucket = 'bucket-name'; // configure this as per instructions above
- const b2UrlPath = `/file/${b2Bucket}/`;
- addEventListener('fetch', event => {
- return event.respondWith(fileReq(event));
- });
- // define the file extensions we wish to add basic access control headers to
- const corsFileTypes = ['png', 'jpg', 'gif', 'jpeg', 'webp'];
- // backblaze returns some additional headers that are useful for debugging, but unnecessary in production. We can remove these to save some size
- const removeHeaders = [
- 'x-bz-content-sha1',
- 'x-bz-file-id',
- 'x-bz-file-name',
- 'x-bz-info-src_last_modified_millis',
- 'X-Bz-Upload-Timestamp',
- 'Expires'
- ];
- const expiration = 31536000; // override browser cache for images - 1 year
- // define a function we can re-use to fix headers
- const fixHeaders = function(url, status, headers){
- let newHdrs = new Headers(headers);
- // add basic cors headers for images
- if(corsFileTypes.includes(url.pathname.split('.').pop())){
- newHdrs.set('Access-Control-Allow-Origin', '*');
- }
- // override browser cache for files when 200
- if(status === 200){
- newHdrs.set('Cache-Control', "public, max-age=" + expiration);
- }else{
- // only cache other things for 5 minutes
- newHdrs.set('Cache-Control', 'public, max-age=300');
- }
- // set ETag for efficient caching where possible
- const ETag = newHdrs.get('x-bz-content-sha1') || newHdrs.get('x-bz-info-src_last_modified_millis') || newHdrs.get('x-bz-file-id');
- if(ETag){
- newHdrs.set('ETag', ETag);
- }
- // remove unnecessary headers
- removeHeaders.forEach(header => {
- newHdrs.delete(header);
- });
- return newHdrs;
- };
- async function fileReq(event){
- const cache = caches.default; // Cloudflare edge caching
- const url = new URL(event.request.url);
- if(url.host === b2Domain && !url.pathname.startsWith(b2UrlPath)){
- url.pathname = b2UrlPath + url.pathname;
- }
- let response = await cache.match(url); // try to find match for this request in the edge cache
- if(response){
- // use cache found on Cloudflare edge. Set X-Worker-Cache header for helpful debug
- let newHdrs = fixHeaders(url, response.status, response.headers);
- newHdrs.set('X-Worker-Cache', "true");
- return new Response(response.body, {
- status: response.status,
- statusText: response.statusText,
- headers: newHdrs
- });
- }
- // no cache, fetch image, apply Cloudflare lossless compression
- response = await fetch(url, {cf: {polish: "lossless"}});
- let newHdrs = fixHeaders(url, response.status, response.headers);
- if(response.status === 200){
- response = new Response(response.body, {
- status: response.status,
- statusText: response.statusText,
- headers: newHdrs
- });
- }else{
- response = new Response('File not found!', { status: 404 })
- }
- event.waitUntil(cache.put(url, response.clone()));
- return response;
- }

6.workers里添加路由,使访问你的域名时,先走workers

访问一下你的图片文件
比如说一开始是https://f000.backblazeb2.com/file/backblaze1489498/wallhaven-md2x8m.jpg
现在用https://dlcu.cf/wallhaven-md2x8m.jpg就可以访问了
7.配置ShareX.
这个感觉没啥好说的,主页面--目标--上传目标设置--backblaze b2,填上就行了

结束
这个的好处就是方便了上传,自己在电脑前,截一下图直接上传,或者复制一下直接上传
还有就是可以用自己的域名,再说的话就是数据自己也能找回.
