【Python之路】特别篇--微信Web网页版通信的全过程分析

　　文章所使用Python版本为py3.5

1.微信服务器返回一个会话ID

微信Web版本不使用用户名和密码直接登录，而是采用二维码登录，所以服务器需要首先分配一个唯一的会话ID，用来标识当前的一次登录。

通过查看网络请求我们找到了这个 二维码图片代表的随机字符串，（IcelandB9Entig==），

2.通过会话ID获得二维码

然后找到该随机字符串的来源请求

请求方式为 GET形式 ， 具体连接为：

https://login.wx.qq.com/jslogin?
appid=wx782c26e4c19acffb
&redirect_uri=https%3A%2F%2Fwx.qq.com%2Fcgi-bin%2Fmmwebwx-bin%2Fwebwxnewloginpage
&fun=new&lang=zh_CN
&_=1492591577859

我们只需要改变最后一个变量 _值即可获得新的字符串序列: (这个值是当前距离林威治标准时间的毫秒）可以自行构造!

通过分割,我们就可以获得随机字符串,自己在前端页面上构造一个二维码出来.

前端二维码页面

3.轮询手机端是否已经扫描二维码并确认在Web端登录

当我们还没进行扫码登录时,发现微信web网页会自动向服务器 轮询手机端是否已经扫码并且确认登录!!

每一分钟发送一次，如果没有登录，请求会返回

window.code=408;

扫码后为

window.code=201;

确认登陆后为:

window.code=200;
window.redirect_uri="https://wx2.qq.com/cgi-bin/mmwebwx-bin/webwxnewloginpage?ticket=A_ToQqd_AFXpsrLMH6RNgi3W@qrticket_0&uuid=we6XJEZYDg==&lang=zh_CN&scan=1492592531";

需要获得其中的跳转url，对rensponse进行分割后取得。

redirect_url = re.split('=', http_res_code.text, 2)[-1].strip().replace('"', '').replace(';', '')

4.访问登录地址，获得uin和sid

在接下来的连接中,我们发现服务器发给了我们skey,sid,pass_ticket 的重要信息, 分析发现该请求的发送地址为: GET方式,

https://wx2.qq.com/cgi-bin/mmwebwx-bin/webwxnewloginpage?ticket=A_ToQqd_AFXpsrLMH6RNgi3W@qrticket_0&uuid=we6XJEZYDg==&lang=zh_CN&scan=1492592531
&fun=new&version=v2

发现,该请求地址为 跳转url + &fun=new&version=v2 构造而成!

直接GET发送请求,我们就拿到返回信息,发现是 xml 格式的数据!

构造一个方法方便获取我们的连接信息

def auth_analysis(self,str_xml):
    '''
    xml中取出数据,返回字典
    :param http_res_ticket:
    :return:
    '''
    from xml.etree import ElementTree as ET
    root = ET.XML(str_xml)
    ret = {}
    for child in root:
        ret[child.tag] = child.text
    return ret

我们还需要获得该请求下的cookies参数,直接通过requests模块的  requests.cookies.get_dict()

# 获取xml 登录信息
user_ticket_url  = redirect_url+ '&fun=new&version=v2'
user_xml_ticket = requests.get(user_ticket_url)

TICKET_COOKIR = user_xml_ticket.cookies.get_dict()
ALL_COOKIE_DICT.update(TICKET_COOKIR)       #记录cookies

# 获取xml中信息
user_ticket_dic = self.auth_analysis(user_xml_ticket.text)
USER_RESULT_DICT.update(user_ticket_dic)      #记录xml中的具体信息

5.初使化微信信息

# 初始化Url :
USER_INIT_URL = 'https://wx2.qq.com/cgi-bin/mmwebwx-bin/webwxinit?pass_ticket={0}&skey={1}&r={2}'

pass_ticket,skey为上一步骤获得的xml信息树中,r为时间戳

# 初始化准备
user_init_payload = {
    'BaseRequest': {
        'DeviceID': 'e' + repr(random.random())[2:17],
        'Sid': USER_RESULT_DICT['wxsid'],
        'Skey': USER_RESULT_DICT['skey'],
        'Uin': int(USER_RESULT_DICT['wxuin']),
    }
}
# 初始化url
user_init_url = USER_INIT_URL.format(USER_RESULT_DICT['pass_ticket'],USER_RESULT_DICT['skey'],int(time.time()))

# payload 转换成bytes
data = (json.dumps(user_init_payload)).encode()

request = urllib.request.Request(url=user_init_url, data=data)
request.add_header(
    'ContentType', 'application/json; charset=UTF-8')

response = urllib.request.urlopen(request)
data = response.read()
# 获得初始化用户数据..
obj = json.loads(data.decode('utf-8'))
INIT_RESULT_DICT.update(obj)
View Code

这一步的发送请求,使用了urllib.requests来发送,注意格式转换!

此时我们已经获得了服务端返回的部分数据.如果需要进一步获取全部信息,......如下

6.获得所有的好友列表

该请求返回了全部的用户信息.

https://wx2.qq.com/cgi-bin/mmwebwx-bin/webwxgetcontact?
pass_ticket=YK57xcgn4qT0n0qoGtxvtLvsV6XXzTDka7Z9DOFAIcGDK0wtZ6GrNpGdHGIHKiiu
&r=1492592546748
&seq=0
&skey=@crypt_8226323c_fd634988b8e43769cb3b7b9fc99ca549

构造请求并发送:

class ContactHandler(tornado.web.RequestHandler):
    def get(self, *args, **kwargs):
        try:
            user_list_url = "https://wx2.qq.com/cgi-bin/mmwebwx-bin/webwxgetcontact?pass_ticket={0}&r={1}&seq=0&skey={2}"
            user_list_url = user_list_url.format(USER_RESULT_DICT['pass_ticket'],USER_RESULT_DICT['skey'],int(time.time()))

            conn = requests.get(url = user_list_url , data={} , cookies=ALL_COOKIE_DICT , headers={'contentType':'application/json; charset=UTF-8','Referer':'https://wx.qq.com/?&lang=zh_CN'})
            # print(conn.encoding)  # ISO-8859-1
            conn.encoding = 'utf-8'
            USER_LIST_DICT.update(json.loads(conn.text))
            # print(USER_LIST_DICT)

            self.render('contact_list.html', user_list_dict=USER_LIST_DICT, user=CURRENT_USER)
        except Exception:
            self.redirect('/login')
获得所有信息的handler

7.保持与服务器的信息同步

与服务器保持同步需要在客户端做轮询，该轮询的URL如下：

https://webpush.wx2.qq.com/cgi-bin/mmwebwx-bin/synccheck?
r=1492594498787
&skey=%40crypt_8226323c_fd634988b8e43769cb3b7b9fc99ca549
&sid=mM%2BFZGbHxGcO3x93
&uin=976834800
&deviceid=e738560216565557
&synckey=1_661566297%7C2_661566394%7C3_661565574%7C11_661566180%7C13_661374753%7C201_1492594315%7C203_1492582669%7C1000_1492594202%7C1001_1492563271
&_=1492592515065

skey,sid,uin,与上面步骤的值相对应此处的synkey是上步步骤获得的同步键值，但需要按一定的规则组合成以下的字符串：

1_124125|2_452346345|3_65476547|1000_5643635 

sync_data_list = []
for item in INIT_RESULT_DICT['SyncKey']['List']:
    temp = "%s_%s" % (item['Key'], item['Val'])
    sync_data_list.append(temp)
sync_data_str = "|".join(sync_data_list)
合成synckey

| 被URL编码成%7C，通过对上面的地址发送请求:，

res_sync = requests.get(synccheck_url,params=payloads,cookies = ALL_COOKIE_DICT)

会返回如下的字符串：

window.synccheck={retcode:"0",selector:"0"}

当有人发送信息给你时, :

window.synccheck={retcode:"0",selector:"2"}

8.获得别人发来的消息

我们通过该URL地址获取发送给我们的消息:

https://wx2.qq.com/cgi-bin/mmwebwx-bin/webwxsync?
sid=XQvf1MmZ7W8O2BU2
&skey=@crypt_75efaa00_3afa77c01d45461eef7eac88da37f70d
&pass_ticket=YArFw%252BDpJHCpRtKCTTabpe2ytETBDmYsp%252BB7ywe%252BtplmzxQZ6ohX7d14sJgjgk6T

制造相应的payload 发送GET请求,获得返回response数据

if 'selector:"2"' in res_sync.text:

    fetch_msg_url = 'https://wx2.qq.com/cgi-bin/mmwebwx-bin/webwxsync?sid={0}&skey={1}&pass_ticket={2}'
    fetch_msg_url = fetch_msg_url.format(USER_RESULT_DICT['wxsid'],USER_RESULT_DICT['skey'],USER_RESULT_DICT['pass_ticket'])

    payloads = {
        'BaseRequest': {
            'DeviceID': 'e' + repr(random.random())[2:17],
            'Sid': USER_RESULT_DICT['wxsid'],
            'Skey': USER_RESULT_DICT['skey'],
            'Uin': int(USER_RESULT_DICT['wxuin']),
        },
        'SyncKey' : INIT_RESULT_DICT['SyncKey'],
        'rr' : int(time.time())
    }

    # payload 转换成bytes
    data = (json.dumps(payloads)).encode()

    request = urllib.request.Request(url=fetch_msg_url, data=data)
    request.add_header(
        'ContentType', 'application/json; charset=UTF-8')

    response = urllib.request.urlopen(request)
    data = response.read()

    # 获得初始化用户数据..
    res_fetch_msg_dict = json.loads(data.decode('utf-8'))
    INIT_RESULT_DICT['SyncKey'] = res_fetch_msg_dict['SyncKey']

    for item in res_fetch_msg_dict['AddMsgList']:
        print(item['FromUserName'], "---->", item['ToUserName'], ":::::", item['Content'])
View Code

9.向用户发送消息

用户主动发送消息，通过以下的URL地址：

https://wx2.qq.com/cgi-bin/mmwebwx-bin/webwxsendmsg
?pass_ticket=mRfzOKMZdUAfqrZVaT7VZeroYNX6SgTtO7WzDwDXmiZvwWC0iWlln2fBuGa8oeld

上面的pass_ticket参数不再解释了，访问该URL采用POST方式，payload如以下的格式：

message = self.get_argument('message')         # 需要发送的信息
to_username = self.get_argument('username')    # 接收人的id  好友列表中获取
print(message,to_username) 
#
send_url = 'https://wx2.qq.com/cgi-bin/mmwebwx-bin/webwxsendmsg?pass_ticket={0}'
send_url = send_url.format(USER_RESULT_DICT['pass_ticket'])
time_str = str(int(time.time()))
payloads = {
    'BaseRequest': {
        'DeviceID': 'e' + repr(random.random())[2:17],
        'Sid': USER_RESULT_DICT['wxsid'],
        'Skey': USER_RESULT_DICT['skey'],
        'Uin': int(USER_RESULT_DICT['wxuin']),
    },
    'Msg': {
        'ClientMsgId': time_str,
        'Content': message,
        'FromUserName': CURRENT_USER['UserName'],     # 自己的用户信息,在微信初始化时获得!
        'LocalID': time_str,
        'ToUserName': to_username,
        'Type': 1,
    },
    'Scene': 0,
}

# payload 转换成bytes
data = (json.dumps(payloads)).encode()
request = urllib.request.Request(url=send_url, data=data)
request.add_header(
    'ContentType', 'application/json; charset=UTF-8')

response = urllib.request.urlopen(request)
data = response.read()

# 获得初始化用户数据..
res_fetch_msg_dict = json.loads(data.decode('utf-8'))

print(res_fetch_msg_dict)
View Code

　　BaseRequest都是授权相关的值，与上面的步骤中的值对应，Msg是对消息的描述，包括了发送人与接收人，消息内容，消息的类型(1为文本)，ClientMsgId和LocalID由本地生成。rr可用当前的时间。在返回JSON结果中BaseResponse描述了发送情况，Ret为0表示发送成功。

注意:

该流程在py3环境下,使用了Tornado框架 和 requests 包 和 urllib.requests 包

urllib.requests 包 具体用法参考如下示例:

# payload 转换成bytes
data = (json.dumps(payload)).encode()

request = urllib.request.Request(url=user_init_url, data=data)
request.add_header(
    'ContentType', 'application/json; charset=UTF-8')

response = urllib.request.urlopen(request)
# 获得数据
data = response.read()
obj = json.loads(data.decode('utf-8'))
# 保存数据
INIT_RESULT_DICT.update(obj)
