自动网页登录，填写表单可以用 puppeteer 实现

vcpkg 会从 github 拉取源码很容易出现网络超时问题。所以根本解决办法是科学啊上网，我用的是v2。

通过环境变量设置HTTP代理：
powershell 设置方法
$env:HTTP_PROXY="127.0.0.1:10809"

实际上我没有设置环境变量，应该是vcpkg自动检测到了系统代理。

PS D:\helloworld> vcpkg install --host-triplet=x64-mingw-dynamic
Detecting compiler hash for triplet x64-mingw-dynamic...
-- Automatically setting %HTTP(S)_PROXY% environment variables to "127.0.0.1:10809".

有个opengl很大，100多M，一直卡着下不来

D:\dev\vcpkg\buildtrees\versioning_\versions\opengl-registry\22f7aa58ee78c9f0db904b6251e9265f2be26f9d: info: installing overlay port from here
-- Downloading https://github.com/KhronosGroup/OpenGL-Registry/archive/3530768138c5ba3dfbb2c43c830493f632f7ea33.tar.gz -> KhronosGroup-OpenGL-Registry-3530768138c5ba3dfbb2c43c83049

解决办法，可以手动下载，然后放到 vcpkg/downloads/ 目录下，即可。我的vcpkg根目录是 "d:/dev/vcpkg"

D:/dev/vcpkg/downloads/KhronosGroup-OpenGL-Registry-3530768138c5ba3dfbb2c43c830493f632f7ea33.tar.gz

POST请求的嘛，你搞错GET了

领StarkNet空投？

参考
https://github.com/tailwindlabs/tailwindcss/pull/7742
安装postcss-remove-rules
然后 postcss.config.js 配置

module.exports = {
  plugins: {
    tailwindcss: {},
    autoprefixer: {},
    "postcss-remove-rules": {
      rulesToRemove: {
        "img,\nvideo": "height",
      },
    },
  },
}

你不发连接，怎么给你下

优化后。我们解析请求header 中 Range实现分片下载。这样就能实现拖拽播放，不用将文件一次性全部下载完毕。

@GetMapping("/download")
    public void download(HttpServletResponse res, HttpServletRequest request, @RequestParam("fileName") String fileName) {
        GetObjectArgs objectArgs = GetObjectArgs.builder().bucket(BUCKETNAME)
                .object(fileName).build();
        StatObjectArgs statObjectArgs = StatObjectArgs.builder().bucket(BUCKETNAME).object(fileName).build();

        long fileSize;
        try {
            fileSize = minioClient.statObject(statObjectArgs).size();
        } catch (Exception e) {
            log.error("文件下载失败:{}", fileName, e);
            return;
        }

        String range = request.getHeader("Range");
        if(range != null && range.startsWith("bytes=")) {
            try {
                int idx = range.indexOf("-");
                long start = Long.parseLong(range.substring("bytes=".length(), idx));
                long end = minioClient.statObject(statObjectArgs).size() - 1;
                if (idx + 1 < range.length()) {
                    end = Long.parseLong(range.substring(idx + 1));
                }
                long length = end - start + 1;
                InputStream inputStream = minioClient.getObject(GetObjectArgs.builder().bucket(BUCKETNAME).object(fileName).offset(start).length(length).build());
                res.setStatus(HttpServletResponse.SC_PARTIAL_CONTENT);
                res.setHeader("Content-Range", "bytes " + start + "-" + end + "/" + fileSize);
                res.setContentType("application/octet-stream");
                res.setHeader("Content-Disposition", "attachment; filename=" + FileUtil.getName(fileName));
                res.setContentLength((int)length);
                try {
                    IOUtils.copy(inputStream, res.getOutputStream());
                    inputStream.close();
                    res.flushBuffer();
                } catch (ClientAbortException e) {
                    // pass
                }
            } catch (Exception e) {
                log.error("断点下载失败:{}", fileName, e);
            }
        } else {
            try (InputStream is = minioClient.getObject(objectArgs)) {
                res.setContentType("application/octet-stream");
                res.addHeader("Content-Disposition", "attachment;filename=" + FileUtil.getName(fileName));
                res.setContentLength((int)fileSize);
                IOUtils.copy(is, res.getOutputStream());
                res.flushBuffer();
            } catch (Exception e) {
                log.error("文件下载失败:{}", fileName, e);
            }
        }
    }

优化前代码

@GetMapping("/download")
public void download(HttpServletResponse res, @RequestParam("fileName") String fileName) {
        GetObjectArgs objectArgs = GetObjectArgs.builder().bucket(BUCKETNAME)
                .object(fileName).build();
        try (GetObjectResponse response = minioClient.getObject(objectArgs)){
            byte[] buf = new byte[1024];
            int len;
            try (FastByteArrayOutputStream os = new FastByteArrayOutputStream()){
                while ((len=response.read(buf))!=-1){
                    os.write(buf,0,len);
                }
                os.flush();
                byte[] bytes = os.toByteArray();
                res.setCharacterEncoding("utf-8");
                res.setContentType("application/octet-stream");
                res.setContentLength(bytes.length);
                res.addHeader("Content-Disposition", "attachment;filename=" + FileUtil.getName(fileName));
                try (ServletOutputStream stream = res.getOutputStream()){
                    stream.write(bytes);
                    stream.flush();
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

文件是存在对象存储 MinIO 上面的，这里是视频文件，前端页面需要播放。
Java后端开发一个文件下载接口，这里没有直接提供minio的地址。问题是前端播放器播放视频的时候，会把整个视频下载完毕，播放也不能拖拽播放，只能从头到尾顺序播放。
用户体验很差

这都3年没更新了，换个吧

哪儿报错，你得先说清楚啊。

不懂编程的话，那是挺难的

直接用开源的cms做吧，关键词 wordpress

有好几种方式

这我遇到过。参考这个链接
https://github.com/microsoft/WSL/issues/4299
https://utf9k.net/blog/wsl2-vhd-issue/

进入 C:\Users{你的用户名}\AppData\Local\Packages，你安装的wsl就放在这个目录下，然后找到文件夹名匹配你安装的操作系统，比如我的是 CanonicalGroupLimited.Ubuntu22.04LTS_79rhkp1fndgsc，然后右键高级，选择，把压缩内容以便节约磁盘空间 勾去掉，就解决了！！

还不跑路，等着干嘛
