Arcaea-server

一个微型的Arcaea本地服务器 A small local server for Arcaea

简介 Introduction

这是基于Python以及Flask的微型本地Arcaea服务器，可以模拟游戏的主要功能。这可能是我第一次写这种大程序，若有不妥之处，敬请谅解。

本程序主要用于学习研究，不得用于任何商业行为，否则后果自负，这不是强制要求，只是一个提醒与警告。

This is a small local Arcaea server based on Python and Flask, which can simulate the main functions of the game. This may be the first time I have written such a large program. Please understand if there is something wrong with it.

This procedure is mainly used for study and research, and shall not be used for any commercial activities, otherwise the consequences will be borne by oneself. This is not a mandatory requirement, just a reminder and warning.

虽然看起来很蠢，但是可以用！ It looks stupid, but it works!

arcaea-server's Issues

iOS，用户购买信息修改，全部解锁后导致进入游戏时闪退

问题如题，闪退处在logo出来的地方，点击进入游戏门关上就闪退了
目前知道的解决方法就是把解锁的内容重新封回去（删除数据库内对应内容）

Unable to connect

Windows 10 20H2 x64
Android 9 (rev 4.9 kernel)
Arcaea 3.6.1c
Python 3.9.1
Arcaea-server 2.4

Can't connect to the local server whether or not I have enabled redirect or try to set up a proxy
is there any workaround to connect properly ?

一个奇怪的打开方式和出现的问题

系统是Win10 LTSC，前几天刚装的
Python3.9也是正常安装和配置好的
我用的方法是使用AdGuardHome，填写规则把本地服务器地址解析成arcapi.lowiro.com
应用到全局之后我整个网络都是可以直接指向服务器，
手机本地终端ping一下也能正常解析，
但问题来了——Arcaea客户端不认，Could not connect to online server
淦，亏我准备了这么多(
不过我也不确定我的AdGuardHome有没有正确配置，不过既然手机能ping通的话应该是没有问题的吧？
设备是MIX3，有root，面具，edxp，模块影响SSL验证的都关掉了
之前我是照着教程整的Charles，但是觉得太麻烦就(

my friend hosted it

Yume没有语音

对这件事有很大执念（x）

「Lets talk about how to make the coder crazy.」

about download

how to download all songs in 1 pack?, I can only download songs one by one in 1 pack..

关于错误输出

似乎在出现错误的时候完全没有任何输出, 导致难以定位错误
如果有错误输出, 希望能告知如何开启
如果没有, 希望能够添加, 以免出现任何问题连个错误日志都无法提交.
谢谢
以及我刚刚看了下您写的wiki 您的config里开启更详细的错误日志也不会在控制台出现错误日志
log里边的错误日志是flask的 控制台的错误日志也是flask的
服务器内部错误并没有被输出
希望您能改进一下
谢谢

部分新注册账号无法正常结算

曲目在服务器有记录，官方端也一样

建议注册时默认源点可于配置文件中修改

（

注册时默认源点从 114514 改为 0

为iOS和iPadOS开放TestFlight或IPA包安装

README文件里面只有APK包,只能给Android设备用。。

同步存档疑似会自动上传存档的所有成绩到在线服务器

如该图左下角的三个相同成绩，在其他曲目均相同。应该是上传本地存档到服务器导致的（不清楚）。

The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.

While it's working just fine on Windows and change int(path[22:]) to int(path[21:]) somehow fixes this problem, maybe it's better to use split() to get the last portion of the URL?

Anyway, thanks for your awesome work. 👍

implement a server on android for 3.6+

is it possible to implement a server on android for version 3.6+?
see the requirements such as doing remote mapping in that version, is it possible to do it on android?

为什么尝试在arcsong.db中添加歌曲信息时会显示Error: no such table: chart呢？

为什么尝试在arcsong.db中添加歌曲信息时会显示Error: no such table: chart呢？

Emm...I've just followed your mannual. As in ver.2.9 there is no song data in "arcsong.db", I want to add some in it, but I just can't...

或者我可以使用以前版本（2.8及以下）的数据库嘛？
好像服务器运行正常的说

下载官方新歌曲的问题

环境

• Ubuntu 20.04 TLS
• Python 3.7.1
• Nginx 1.8 反代
• Android 10 over Root 系统信任证书

问题

下载歌曲时提示

下载歌曲时发生问题。请重试一次。

其他注册登录购买之类的功能工作的很nice，但在下载这里有点不明白，在解锁了音乐包后，下载音乐包里面的歌曲会出现错误提示，100%复现。

看了下wiki里的关于歌曲下载，可能是需要自己手动去添加歌曲的本地文件？想问问官方歌曲也需要这样嘛。还是可能我哪里没有配置到位（）

可以具体讲一下如何在安卓端连接服务器吗
大佬你好，我在自己的Linux服务器端（Debian9）成功跑起来了，config.py几乎没做改动
在我的手机上，我并不清楚如何设置，所以我连接WiFi后在高级选项中设置手动代理，主机我设置了自己的域名（指向了服务器IP），端口设置的是我在config.py中设置的8080，之后我也尝试了10900和10901（LINK_PLAY的俩端口）。之后我在flask输出的日志中看到了访问baidu.com这类的日志，我的手机显示无法上网,，说明服务器访问成功了。
之后，我寻思没用户名和密码，于是我把服务器上的arcaea_database.db复制到本地，用一个查看器把user表加了一行（其它表没动过），基本与你给的恶臭的那一行差不多，用户名和密码自己填的。然后我把它替换了服务器上的数据库。
然后，我登录游戏，发现显示密码或用户名错误。
于是我在/web/login路由的修改密码中把密码修改了（查询用户查询得到），此时复制服务器上的数据库，发现user表我的密码看不懂（64个字符）。
然后，我又一次登录游戏，发现显示密码或用户名错误。

附加内容
大佬我觉得我们其实很“镜像”，你用的flask和sqlite3，我正好也只会一点点，当然了，你在这方面的研究比我深得多。
希望能尽快回复我吧，谢谢。

可否再出一篇教程具体说明一下如何引导Arcaea访问本地服务器呢 有点没看懂说明文档（）

设置全解锁搭档后，会出现无法登录的问题

CHARACTER_FULL_UNLOCK设置为True后，登录时自动添加的搭档等级恒为None，导致需要利用搭档等级计算数值的函数出错，导致无法登录
（如 https://github.com/Lost-MSth/Arcaea-server/blob/master/latest%20version/server/character.py#L114）

/coffee/12/compose/aggregate应该是批量请求的接口

`每个call中的endpoint都应该是一条'/coffee/12'+call[i]['endpoint']的请求
官方那边是一条URL塞超过6个子请求就直接封号，所以id应该不会>5
然后是返回

{
"success": true,
"value": [
{"id": 0, "value": {response0}},
{"id": 1, "value": {response1}},
{"id": 2, "value": {response2}},
{...}
]
}

语文不好，可能表述不是很清楚(

4.0客户端如何绕过（或删除）SSL使客户端连接localhost

请问如何使4.0客户端如何绕过（或删除）SSL使客户端连接localhost

我在ida中找了很久也试过了很多方法没没能绕过ssl去修改api

实在是没办法了，问了很多人都对这个一无所知QAQ

关于api接口

/users、/songs、/user/me、/user/<userid>/best使用get方法不可用

A question about using the API

Hello, I'm using the API in the Arcara-server. I want you use the songs and the users to get the song list and best 30. However, I always receive 400 error. Do you have some suggestions or some examples for using these APIs? Thanks very much!

站点添加ssl后无法登录后台

这次更新后出现了如题的情况

复现方法：
1.把服务器通过Nginx反代出去
2.给反代域名添加ssl
3.通过https://<反代域名>/web访问后台
4.尝试登录
5.点击登录后，登录页面会刷新，并没有进入后台页面
6.关闭ssl，通过http://<反代域名>/web访问后台并登录，可以正常进入后台页面
（我不是很会描述这个原谅我1551）

服务端版本迭代后登录提示未知错误

更新操作为压缩包内文件覆盖到目录，在网页端上传旧数据库。客户端也更新了新的版本。
提示未知错误，但重新输入账号密码仍可正常登录（估计是 token 获取不到）

注册接口返回308

Arcaea-server/latest version/main.py

Line 217 in d0be49f

@app.route(add_url_prefix('/user/'), methods=['POST']) # 注册接口

RT，版本3.9.1c，注册时客户端请求的是'/user'（没有斜杠）

谱面下载添加一次性 token 验证和日限额

为了防止被恶意刷下载流量，希望下载链接能添加一次性 token 验证和日限额。

Missing some songs from database

Single: pupa

World songs: 'redandblue3', 'ignotus3', 'singularity3', 'dropdead3', 'arcahv'

Note: those byd songs are April Fools charts. Without them they will never been shown.

求解

使用Nginx反向代理到内网，结果发现只要POST的请求就400，很多操作做不了（？？）

配置：

    proxy_set_header Host 127.0.0.1;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header REMOTE-HOST $remote_addr;
#    error_page   405 =200 @405;    
#    proxy_method POST;    
    add_header X-Cache $upstream_cache_status;
    proxy_redirect http:// $scheme://;
    #Set Nginx Cache    
        add_header Cache-Control no-cache;
    expires 12h;

Cannot connect the client to localhost

I couldn't get the game to connect to the client, got an EOF during handshake on CONNECT method.

更新服务器版本后无法使用旧版数据库

问题如题
这样一来每次更新都要重新注册账号，PTT重置，包括角色数值，技能在内的都要重新做调整。

Some BYD downloads don't work

Using 47f05cd server with v4.0.255 client.

Songs like Bookmaker, Dement, Fairytale, Goodtek, Infinity Heaven and more.

So I put 3.aff for each song to their song ID folder properly. When downloading the song from client, I saw network requests for both base.ogg, 0.aff, 1.aff, 2.aff, and 3.aff. But after that only PST, PRS, FTR are available but not BYD. Checking the dl container folder also show only the base ogg and 0-2 aff, not showing the BYD aff file.

关于Arcaea3.6.0客户端的问题

Arcaea更新到3.6.0之后
通过Charles请求时，发现会卡在一个Method为CONNECT的方法上
貌似这个Method的CONNECT的连接无法建立时，他下面的POST包也不发了
还有办法让arc连接到本地服务器吗

How to use this? Is this mod script?

Want to know

无法添加歌曲

arcaea version:3.5.5(ios)

然后这曲子并没有出现在游戏里，请问还需要动什么地方？
