Question

我使用的是Django环境，我想从Steam获取统计信息。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：

我使用Python Requests库来GET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steamcommunity.com时，我得到了类似的内容：

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

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

从api.steampowered.com我得到了这个：

{
    "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，为了能够从api.steampowered.com获得任何内容，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文件等。我需要的信息如下（使用XML / JSON响应中的名称）：

播放器

Steamid
Personaname
ProfileURL
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
标志
hoursLast2Weeks

对于游戏总数，我认为我只需计算<game>返回的XML文件中steamcommunity.com个节点的数量。它起作用，因为我能够计算它们，但我似乎无法在totalgames的JSON响应中添加api.steampowered.com字段。其次，并非所有<game>个节点都有<hoursLast2Weeks>个子节点，我只想要那些节点。第三，我想让玩家的朋友一共得到。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，试图关注它们，但我不确定我在哪里出错了。任何帮助将不胜感激。

Answer 1

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)

Answer 2

满足totalgames响应中每个元素的添加players：

import json
response = '{"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"}]}}'
data = json.loads(response)
for player in data["response"]["players"]:
    # add code to get game count by player here                  
    # set to zero for this example
    totalgames = 0
    player["totalgames"] = totalgames

print json.dumps(data, sort_keys=True, indent=4)

解析和混合Steam API调用

播放器

游戏
