前天微软E5开发者账号下来了，美滋滋喜提5T空间和25个子账号，就想着做个私有云盘
云盘是基于Cloudreve搭建的，地址：https://drive.crashblock.top
实测发现下载速度并不理想，在未科学上网的时候下载速度只有3M上下浮动，查资料发现可能是巨硬吧中国大陆南方节点撤了。
所以就查到了可以利用CloudFlare进行反代加速（免费量大速度快美滋滋）
以下是具体操作方法：
1.首先你需要先在CloudFlare有一个配置完成的域名
2.复制你的onedrive域名，就是这里，你可以点击这里来打开你的仪表盘
3.打开你的CloudFlare，点击你左侧的Workers选项，选择概述，点击创建服务
4. 补充说明：在第3步时如果你是第一次使用CloudFlare的Wokers，那么你将要创建一个子域，具体格式为[XXX].workers.dev，[XXX]为你自定义的名称，这里你可以随意填写
5.接上第3步：点击创建服务后，会让你填写服务名称和选择启动器，启动器分为HTTP处理程序和HTTP路由器。服务名称可以随意填写，启动器选择HTTP路由器。
6.创建服务完毕后，点击Workers右边的快速编辑，将下方代码填入右边的编辑栏，注意代码需要根据你自己的onedrive域名进行更改，填写完毕后点击下方的保存并部署。
// 替换成你OneDrive的网址
const upstream = 'XXXXXXXXX'
// 替换成你OneDrive的网址
const upstream_mobile = 'XXXXXXXXX'
// 下面的配置都不用动
const upstream_path = '/'
const blocked_region = ['KP', 'SY', 'PK', 'CU']
const blocked_ip_address = ['0.0.0.0', '127.0.0.1']

})
}
return response;

async function replace_response_text(response, upstream_domain, host_name) {
let text = await response.text()
var i, j;
for (i in replace_dict) {
j = replace_dict[i]
if (i == '$upstream') {
i = upstream_domain
} else if (i == '$custom_domain') {
i = host_name
}
if (j == '$upstream') {
j = upstream_domain
} else if (j == '$custom_domain') {
j = host_name
}
let re = new RegExp(i, 'g')
text = text.replace(re, j);
}
return text;
}
async function device_status(user_agent_info) {
var agents = ["Android", "iPhone", "SymbianOS", "Windows Phone", "iPad", "iPod"];
var flag = true;
for (var v = 0; v < agents.length; v++) {
if (user_agent_info.indexOf(agents[v]) > 0) {

break;
}
}
return flag;
}7.打开你提前在CloudFlare中接入的域名，添加DNS解析，类型为A，名称随意，内容随意，但是务必将代理状态打开
8.点击左侧Workers，点击添加路由。路由内容为: 你刚刚添加的DNS解析的名称+你的域名/,例如你的域名为abcd.com，你刚刚添加的解析名称为ab，则格式为 ab.abcd.com/。下方服务选择你在第3步创建服务时选择的服务名称，例如我这里服务名称为onedrive
9.回到你的Cloudreve，打开Cloudreve仪表盘，选择你的OneDrive存储策略，选择右边的操作，选择专家模式编辑，找到OneDrive 反代服务器地址选项，将你刚刚填写的路由前面加上https://后面去掉/*填进去，例如https://ab.abcd.com。保存更改即可完成反代。
到这里我们再看一下下载速度：
好耶！
