解决Github或Github pages 无法访问
本方法来源于网络！ 作为开发者，经常使用借助GitHub进行开发，但是最近防火墙发力导致本就半死不活的GitHub在河北彻底无法访问github.com站点，所以以下几个办法供参考【ps:不考虑科学上网】 1.修改hosts 打开 http://tool.chinaz.com/dns?type=1&host=www.github.com&ip=选择一个TTL最小的ip,比如我这里是新加坡的ip 之后打开这个路径C:WindowsSystem32driversetc找到hosts,将它复制一份到桌面 通过你的文本编辑器打开这个文件,并输入一行记录13.229.188.59 github.com,同理，如果需要 assets-cdn.github.com[CSS,JS加载慢，添加这个],avatars0.githubusercontent.com[用户头像不能访问，或者访问慢],avatars1.githubusercontent.com[用户头像不能访问，或者访问慢]，使用上面的方法找到dns域名，填入即可。 这种方法并不是一劳永逸的，因为nds时刻在变，所以一旦不能访问，还是先找可访问的dns域名吧。 2.Cloudflare Workers 反代 利用Cloudflare Workers搭建一个GitHub镜像供自己使用 在 cloudflare 上创建一个 worker 将下面所有内容拷贝，覆盖粘贴到 worker 里面，保存 const config = {
basic: {
upstream: 'https://github.com/',
mobileRedirect: 'https://github.com/',
},
firewall: {
blockedRegion: ['KP', 'SY', 'PK', 'CU'],
blockedIPAddress: [],
scrapeShield: true,
},
routes: {
TW: 'https://github.com/',
},
optimization: {
cacheEverything: false,
cacheTtl: 5,
mirage: true,
polish: 'off',
minify: {
javascript: true,
css: true,
html: true,
},
},
};
async function isMobile(userAgent) {
const agents = ['Android', 'iPhone', 'SymbianOS', 'Windows Phone', 'iPad', 'iPod'];
return agents.any((agent) => userAgent.indexOf(agent) > 0);
}
async function fetchAndApply(request) {
const region = request.headers.get('cf-ipcountry') || '';
const ipAddress = request.headers.get('cf-connecting-ip') || '';
const userAgent = request.headers.get('user-agent') || '';
if (region !== '' && config.firewall.blockedRegion.includes(region.toUpperCase())) {
return new Response(
'Access denied: booster.js is not available in your region.',
{
status: 403,
},
);
} if (ipAddress !== '' && config.firewall.blockedIPAddress.includes(ipAddress)) {
return new Response(
'Access denied: Your IP address is blocked by booster.js.',
{
status: 403,
},
);
}
const requestURL = new URL(request.url);
let upstreamURL = null;
if (userAgent && isMobile(userAgent) === true) {
upstreamURL = new URL(config.basic.mobileRedirect);
} else if (region && region.toUpperCase() in config.routes) {
upstreamURL = new URL(config.routes[region.toUpperCase()]);
} else {
upstreamURL = new URL(config.basic.upstream);
}
requestURL.protocol = upstreamURL.protocol;
requestURL.host = upstreamURL.host;
requestURL.pathname = upstreamURL.pathname + requestURL.pathname;
let newRequest;
if (request.method === 'GET' || request.method === 'HEAD') {
newRequest = new Request(requestURL, {
cf: {
cacheEverything: config.optimization.cacheEverything,
cacheTtl: config.optimization.cacheTtl,
mirage: config.optimization.mirage,
polish: config.optimization.polish,
minify: config.optimization.minify,
scrapeShield: config.firewall.scrapeShield,
},
method: request.method,
headers: request.headers,
});
} else {
const requestBody = await request.text();
newRequest = new Request(requestURL, {
cf: {
cacheEverything: config.optimization.cacheEverything,
cacheTtl: config.optimization.cacheTtl,
mirage: config.optimization.mirage,
polish: config.optimization.polish,
minify: config.optimization.minify,
scrapeShield: config.firewall.scrapeShield,
},
method: request.method,
headers: request.headers,
body: requestBody,
});
}
const fetchedResponse = await fetch(newRequest);
const modifiedResponseHeaders = new Headers(fetchedResponse.headers);
if (modifiedResponseHeaders.has('x-pjax-url')) {
const pjaxURL = new URL(modifiedResponseHeaders.get('x-pjax-url'));
pjaxURL.protocol = requestURL.protocol;
pjaxURL.host = requestURL.host;
pjaxURL.pathname = pjaxURL.path.replace(requestURL.pathname, '/');
modifiedResponseHeaders.set(
'x-pjax-url',
pjaxURL.href,
);
}
return new Response(
fetchedResponse.body,
{
headers: modifiedResponseHeaders,
status: fetchedResponse.status,
statusText: fetchedResponse.statusText,
},
);
}
// eslint-disable-next-line no-restricted-globals
addEventListener('fetch', (event) => {
event.respondWith(fetchAndApply(event.request));
}); 之后通过worker 的子域名来访问GitHub 但是这种方法我是不大推荐的,因为这样不可以登录,也就是说不可以下载,如果想要下载则需要再新建一个worker然后输入以下代码 addEventListener('fetch', event => {
event.respondWith(handleRequest(event.request).catch((err) => { return new Response(err.message) }))
})
const html = `
<html><head><h1 style=\"font-size:32px;font-family:verdana;color:red;\">Github直链加速下载每日10w次调用 </h1></head><body>
<input type=\"url\" placeholder=\"url\" id=\"url\" style=\"border: 6px solid powderblue;color: blue; width: 60%; display: block;\">
