Server-side Channel Development Rules

The MSDK server will send an HTTP (S) POST request to the game's plugin server according to the request:

I. Exchange protocol between the MSDK server and the plugin server

• Interface protocol: HTTP/HTTPS
• Request method: POST
• Request PATH: the address configured in 'Open Platform Channel Creation' according to different channels
• Request parameters: Each request's Query Parameter carries three parameters: channelid, gameid and os. For the parameters in the request body, please see the specific interface, where
  • channelid is the third-party channel's channel ID defined by the MSDK platform
  • gameid is the game's game ID defined by the MSDK platform
  • os is the request source platform defined by the MSDK platform: 1-Android, 2-iOS, 3-Web, 4-Linux, 5-Windows
• Parameter verification rules: If the game needs to verify the legitimacy of the request parameters, this can be processed by the following rules
  • Parameter verification field sig, which is a 32-bit MD5 lowercase string
  • sig filling rules: md5(PATH + "?" + QueryParameter + PostBody + SigKey), where SigKey is the app_key of Open Platform Channel Configuration in the Feiying system

Example:

POST /auth/login/?channelid=101&gameid=10&os=1&sig=4db5bdf075e280757ef4b0d93ad3aacb HTTP/1.1    
Host: openplatformtest.com    
Content-Type: application/json    
Content-Length: 278    

{    
    "appid": "xxxxx",    
    "channel_info": {    
        "access_token": "EAAGBC9HZB9l4BAEWkk4T3b4d2gZCTrQVFmmtPZA6SoH4VCPO0XKkce47LUaOMMdzuo6q7JWM2RDLjyT1nehQWTTLcwyjyvKxy2AeNzPRTkI9dpBz78s5KOYf8omVMfMzrykdKcnQSYuRJ0zaCyaHJ1ZCeOg5HBnc8XnHwYk5EUp9htCFXw7RbTBVNU0rGxAkurqnnMLZC92N5gTbYF4NOUMZBd2iJDa7dmE6RNOb3gPAZDZD"    
    }    
}

II. sig Calculation Process

Take the login interface as an example:

• PATH: /auth/login/ (the management console configuration)
• QueryParameter: channelid=101&gameid=10&os=1
• PostBody: {"channel_info": {"access_token":"fbtoken"}}
• SigKey: xxxxx (the management console configuration)

sig = md5(/auth/login/?channelid=101&gameid=10&os=1{"channel_info": {"access_token":"fbtoken"}}xxxxx) = 111019093c60a14e8ec57c21dbe7243c
