#实用教程#backblaze+cloudflare+ShareX 实现无成本图床和便捷上传

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
#实用教程#backblaze+cloudflare+ShareX 实现无成本图床和便捷上传
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
