Mongodb 和 Postgresql 的数据库设置

Question

将所有文件从 python 2.7 转换为最新版本后，我在运行游戏时遇到了问题。 我收到数据库连接错误。 我有一个文件 Frontend.py 有以下代码：

BIND_PORT = 7071
BIND_ADDRESS = "0.0.0.0"

MONGODB_HOST = "10.0.0.1"
MONGODB_PORT = 27017

DB_USERNAME = "tdta"
DB_PASSWORD = "foobar42"
DB_HOST = "10.0.0.1"
DB_DATABASE = "tdta"

NEW_USER_RATING = 1500

BACKEND_SERVERS = (
( "127.0.0.1", 32073, "th_frontend", "e5e6af02519f110093d76dcc1f55b25d" ),
( "127.0.0.1", 32073, "th_frontend", "e5e6af02519f110093d76dcc1f55b25d" ),
( "127.0.0.1", 32073, "th_frontend", "e5e6af02519f110093d76dcc1f55b25d" ),
)

我有另一个文件 ServerConfig.py 用于后端，代码如下：

SERVER_PORT = 32073
SERVER_FPS = 60.0   # should read back from a config file, but this will do for now
SERVER_FRAME_QUOTA = 2.0/SERVER_FPS

PING_FREQUENCY = 3.0  # once per second if nothing else
LATENCY_BUFFER_LENGTH = 10  # how many latency samples will be stored and averaged to get an average latency measurement
NONACTIVITY_GRACE_PERIOD = 300.0  # if users do absolutely nothing for this amount of seconds the match will be terminated
NONACTIVITY_WARNING_PERIOD = 240.0  # if users do absolutely nothing for this amount of seconds a warning will be sent

VISUALIZE = False
ALLOW_DEBUG = True
ALLOW_DEBUG_COMMANDS = True

MATCH_UNIT_CAP = 400

MONGODB_HOST = "10.0.0.1"
MONGODB_PORT = 27017

FRONTEND_HOST = "127.0.0.1"
FRONTEND_PORT = 7070
FRONTEND_USERNAME = "th_frontend"
FRONTEND_PASSWORD = "e5e6af02519f110093d76dcc1f55b25d"

我知道这个文件需要根据我的 postgresql 和 mongodb 数据库凭据进行配置。

谁能告诉我 th_frontend", "e5e6af02519f110093d76dcc1f55b25d" 是什么？是 postgresql 用户名和密码吗

我确定这适用于 mongodb 连接：

MONGODB_HOST = "10.0.0.1"
MONGODB_PORT = 27017

DB_USERNAME = "tdta"
DB_PASSWORD = "foobar42"
DB_HOST = "10.0.0.1"
DB_DATABASE = "tdta"

但是，当我尝试登录时，使用此凭据显示没有数据库“tdta”，尽管我确信 mongo show dbs 显示了 tdta。

我很困惑

BIND_PORT = 7071
BIND_ADDRESS = "0.0.0.0"

现在尝试从 Unity3D 连接时收到此错误消息。 我仍然无法弄清楚这是什么，因为 mongodb 和 postgresql 具有不同的登录凭据

FRONTEND_USERNAME = "th_frontend"

FRONTEND_PASSWORD = "e5e6af02519f110093d76dcc1f55b25d"

尝试使用 Unity3d 登录时出现错误：

现在尝试从 Unity3D 连接时收到此错误消息。

在snakecharmerb 的帮助下，我得以修复。 我更改了用户名和密码，现在可以登录到 postgresql 数据库。

现在我收到新错误：

我该怎么办？ 我的id是user1，密码是user

Answer 1

错误信息

类型错误：必须在散列之前对 Unicode 对象进行编码

告诉你你需要在散列之前对密码进行编码，所以行

user = authenticate(db, request_dict["username"], md5(request_dict["password"]).hexdigest())

应该

user = authenticate(db, request_dict["username"], md5(request_dict["password"].encode('ascii')).hexdigest())

（如果密码可能包含非 ASCII 字符，您可能希望使用 UTF-8 作为编码）
