解析和混合Steam API调用

Question

我正在使用Django环境,我想从Steam获取统计数据.但是,Steam的API非常愚蠢,因为它们有大约20个不同的URL,我想要的主要信息是:

• http://steamcommunity.com/id/STEAM_USERNAME/games?tab=all&xml=1
• http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key=KEY&steamids=STEAM_ID

我正在使用Python Requests库来GET处理来自Steam的数据.

import requests
import json
from xml.dom.minidom import parseString

STEAM_API_URL = 'http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002'
STEAM_API_KEY = 'XXXXX'
STEAM_USERNAME = 'niteshade'

# Make request to steamcommunity.com with the username to get the 64-bit Steam ID
username_r = requests.get('http://steamcommunity.com/id/{0}/games?tab=all&xml=1'.format(STEAM_USERNAME))
steamid = str(parseString(username_r.text.encode('utf-8')).getElementsByTagName('steamID64')[0].firstChild.wholeText)
totalgames = parseString(username_r.text.encode('utf-8')).getElementsByTagName('game').length

data = {
    'key': STEAM_API_KEY,
    'steamids': steamid,
}

user_r = requests.get(STEAM_API_URL, params=data)
#user_r.json['response']['players'][0].update({'totalgames'.encode('utf-8'): totalgames})

当我查询时,steamcommunity.com我得到这样的东西:

<gamesList>
    <steamID64>12345</steamID64>
    <steamID>aSteamID</steamID>
    <games>
        <game>

            <globalStatsLink>http://steamcommunity.com/stats/BindingOfIsaac/achievements/</globalStatsLink>
        </game>
        <game>

            <storeLink>http://steamcommunity.com/app/19680</storeLink>
        </game>
    </games>

从api.steampowered.com我得到这个:

{
    "response": {
        "players": [
            {
                "steamid": "12345",
                "communityvisibilitystate": 3,
                "profilestate": 1,
                "personaname": "aSteamID",
                "lastlogoff": 1351676021,
                "profileurl": "http:\/\/steamcommunity.com\/id\/aSteamID\/",
                "avatar": "http:\/\/media.steampowered.com\/steamcommunity\/public\/images\/avatars\/b2\/b261f66a17bfa6c95b24f8b4c6b58bb3776d57e4.jpg",
                "avatarmedium": "http:\/\/media.steampowered.com\/steamcommunity\/public\/images\/avatars\/b2\/b261f66a17bfa6c95b24f8b4c6b58bb3776d57e4_medium.jpg",
                "avatarfull": "http:\/\/media.steampowered.com\/steamcommunity\/public\/images\/avatars\/b2\/b261f66a17bfa6c95b24f8b4c6b58bb3776d57e4_full.jpg",
                "personastate": 4,
                "realname": "Real Name",
                "primaryclanid": "103582791429705688",
                "timecreated": 1250966723,
                "loccountrycode": "GB"
            }
        ]       
    }
}

基本上,为了能够获得任何东西api.steampowered.com,我需要一个Steam ID.为此,我打电话给steamcommunity.com网站,该网站返回带有Steam ID的XML文件,以及其他内容.我需要的信息如下(使用XML/JSON响应中的名称):

播放机

• Steamid
• Personaname
• 个人资料网址
• 朋友(我相信需要另一个API调用)
• Personastate
• 游戏总数
• Avatarfull

游戏

• 的AppID
• 名称
• 商标
• hoursLast2Weeks

对于游戏总数,我想我只是计算<game>返回的XML文件中的节点数steamcommunity.com.它起作用,因为我能够计算它们,但我似乎totalgames无法在JSON响应中添加一个字段api.steampowered.com.其次,并非所有<game>节点都有<hoursLast2Weeks>子节点,我只想要那些节点.第三,我想让玩家的朋友总数.我不是在开玩笑,我知道我必须使用另一个GET,但问题是将它添加到JSON中.

我的主要问题是尝试添加到JSON响应中,我已经查看了SO上的其他示例,试图遵循它们,但我不确定我在哪里出错了.任何帮助将不胜感激.

更改json数据非常简单:

jsondata = json.loads(json_input_string)
jsondata['newkey'] = new_value
json_output_string = json.dumps(jsondata)
