Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

引入

import { AliOssAxios } from 'ali-oss-axios';
const getOSSInstance = (() => {
    let instance: AliOssAxios;
    return async () => {
        if (instance) { return instance; }
        const res = await getOssToken(); // getOssToken是获取token方法
        instance = new AliOssAxios({
            // Bucket所在地域。以华东1(杭州)为例,Region填写为oss-cn-hangzhou。
            region: 'xxxx',
            // 从STS服务获取的临时访问凭证。临时访问凭证包括临时访问密钥(AccessKeyId和AccessKeySecret)和安全令牌(SecurityToken)。
            accessKeyId: res.access_key_id,
            accessKeySecret: res.access_key_secret,
            stsToken: res.security_token,
            endpoint: 'oss-accelerate.aliyuncs.com',
            // 填写Bucket名称。
            bucket: 'xxx',
            // 刷新临时访问凭证
            refreshSTSTokenInterval: 60000 * 5, // 5分钟刷新
            refreshSTSToken: async () => {
                const refreshToken = await getOssToken();
                return {
                    accessKeyId: refreshToken.access_key_id,
                    accessKeySecret: refreshToken.access_key_secret,
                    stsToken: refreshToken.security_token,
                };
            },
        });
        return instance;
    };
})();

上传功能

export const uploadOSS = async ({ file }: { file: File }) => {
    const basePath = 'test/dir';
    const path = `${basePath}/${Date.now()}/${file.name}`;
    const aliyunOSS = await getOSSInstance();
    return aliyunOSS.put(path, file);
};

生成下载的文件url

export const getOSSDownloadUrl = async (url: string, fileName: string) => {
    const aliyunOSS = await getOSSInstance();
    // 配置响应头实现通过URL访问时自动下载文件,并设置下载后的文件名。
    const response = {
        'content-disposition': `attachment; filename=${encodeURIComponent(fileName)}`, // 自定义下载后的文件名。
    };
    // 填写Object完整路径。Object完整路径中不能包含Bucket名称。
    url = url.replace(/^http.*\.aliyuncs\.com\//, '');
    url = decodeURIComponent(url);
    return aliyunOSS.signatureUrl(url, { response });
};
