app = Flask(__name__)
app.secret_key = '1231sdfasdf'

@app.route('/login')

    qcode = re.findall('uuid = "(.*)";',rep.text)[0]

if __name__ == '__main__': app.run()

<body>
    <div style=" 200px;margin: 0 auto;">
        <h1 style="text-align: center;">扫码登录</h1>
        <img style=" 200px;height: 200px;" src="https://login.weixin.qq.com/qrcode/{{qcode}}" alt="">
    </div>
</body>

2. 检查登录：扫码

1、登陆的时候需要长连接，一直保持opening的状态

2、因为第一次访问页面的时间仍然需要用到，不能用g（一次请求己结束），选择用session获取的方式

from bs4 import BeautifulSoup

def xml_parse(text):
    result = {}

                }
            })

3. 检查登录：确认登录
　　同上
4. 获取凭证：redirect_uri
　　同上

print(round(1.4))

5. 信息初始化：
- 联系人
- 公众号

6. 获取所有联系人

@app.route('/index')
def index():
    pass_ticket = session['ticket_dict']['pass_ticket']
    init_url = "https://wx.qq.com/cgi-bin/mmwebwx-bin/webwxinit?r=-979112921&lang=zh_CN&pass_ticket={0}".format(pass_ticket)

    rep = requests.post(

                'DeviceID':"e700290354098676",
                'Sid':session['ticket_dict']['wxsid'],
                'Skey':session['ticket_dict']['skey'],
                'Uin':session['ticket_dict']['wxuin'],

    rep.encoding = 'utf-8'

    init_user_dict = rep.json()
    print(init_user_dict)

    return render_template('index.html',init_user_dict=init_user_dict)

index.html

<body>
    <h1>欢迎使用Web微信:{{init_user_dict.User.NickName}}</h1>

    <h3>最近联系人</h3>
    <ul>
        {% for row in init_user_dict.ContactList %}
            <li>{{row.NickName}}</li>
        {% endfor %}
        <li><a href="#">查看所有联系人</a></li>
    </ul>

    <h3>最近公众号</h3>
    {% for item in init_user_dict.MPSubscribeMsgList %}
        <div>
            <h3>{{item.NickName}}</h3>
            <ul>
                {% for msg in item.MPArticleList %}
                <li><a href="{{msg.Url}}">{{msg.Title}}</a></li>
                {% endfor %}
            </ul>
        </div>
    {% endfor %}

</body>

7. 获取联系人列表

1、

@app.route('/contact/list')
def contack_list():
    """
    获取联系人列表
    :return:
    """
    # https://wx.qq.com/cgi-bin/mmwebwx-bin/webwxgetcontact?lang=zh_CN&pass_ticket=Q4pDjGjjdjOnFwfHS5I3XFzFc4ApHkTaKzlCOdh34uTVavWegV%252BUky37VviDufnO&r=1530064956758&seq=0&skey=@crypt_2ccf8ab9_fbbb31c98b1a1c12b4ec707678dd336e
    # GET
    ctime = int(time.time() * 1000)
    pass_ticket = session['ticket_dict']['pass_ticket']
    skey = session['ticket_dict']['skey']
    contact_url = "https://wx.qq.com/cgi-bin/mmwebwx-bin/webwxgetcontact?lang=zh_CN&pass_ticket={0}&r={1}&seq=0&skey={2}".format(pass_ticket,ctime,skey)

    res = requests.get(
        url=contact_url,
        cookies=session['ticket_cookies']
    )
    res.encoding = 'utf-8'
    user_list = res.json()

    return render_template('contact_list.html',user_list=user_list)

contact_list.html

<body>
    <h1>联系人列表</h1>
    <ul>
        {% for user in user_list.MemberList %}
            <li>
                <img style="height: 50px; 50px;" src="/get_img?prev={{user.HeadImgUrl}}">
                <span>用户名：{{user.NickName}} 唯一标识：{{user.UserName}}</span>
            </li>
        {% endfor %}

    </ul>
</body>

在获取用户图片

@app.route('/get_img')
def get_img():
    prev = request.args.get('prev') # /cgi-bin/mmwebwx-bin/webwxgeticon?seq=686005187
    username = request.args.get('username') # @9c4df5e041eb06725a410a3d9d580877e229066895b3e91d44a7af8be37e0e5b
    skey = request.args.get('skey') # @crypt_ac8812af_a5601beadce3211cdb4fd3663d08ab52

    head_img_url = "https://wx.qq.com{0}&username={1}&skey={2}".format(prev,username,skey)

    rep = requests.get(
        url=head_img_url,
        cookies=session['ticket_cookies']
    )

    return rep.content

8. 发送消息

@app.route('/send/msg',methods=['GET','POST'])
def send_msg():
    if request.method == "GET":
        return render_template('send_msg.html')

    ctime = int(time.time() * 1000)
    from_user = request.form.get('fromUser')
    to_user = request.form.get('toUser')
    content = request.form.get('content')

    data_dict = {
        'BaseRequest':{
                'DeviceID':"e700290354098676",
                'Sid':session['ticket_dict']['wxsid'],
                'Skey':session['ticket_dict']['skey'],
                'Uin':session['ticket_dict']['wxuin'],
        },
        'Msg':{
            'ClientMsgId':ctime,
            'Content':content,
            'FromUserName':from_user,
            'LocalID':ctime,
            'ToUserName':to_user,
            'Type':1
        },
        'Scene':0
    }

    msg_url = "https://wx.qq.com/cgi-bin/mmwebwx-bin/webwxsendmsg?lang=zh_CN&pass_ticket={0}".format(session['ticket_dict']['pass_ticket'])
    rep = requests.post(
        url=msg_url,
        data=bytes(json.dumps(data_dict,ensure_ascii=False),encoding='utf-8')
    )

    print(rep)

    return "发送成功"

send_msg.html

@app.route('/send/msg',methods=['GET','POST'])
def send_msg():
    if request.method == "GET":
        return render_template('send_msg.html')

    ctime = int(time.time() * 1000)
    from_user = request.form.get('fromUser')
    to_user = request.form.get('toUser')
    content = request.form.get('content')

    data_dict = {
        'BaseRequest':{
                'DeviceID':"e700290354098676",
                'Sid':session['ticket_dict']['wxsid'],
                'Skey':session['ticket_dict']['skey'],
                'Uin':session['ticket_dict']['wxuin'],
        },
        'Msg':{
            'ClientMsgId':ctime,
            'Content':content,
            'FromUserName':from_user,
            'LocalID':ctime,
            'ToUserName':to_user,
            'Type':1
        },
        'Scene':0
    }

    msg_url = "https://wx.qq.com/cgi-bin/mmwebwx-bin/webwxsendmsg?lang=zh_CN&pass_ticket={0}".format(session['ticket_dict']['pass_ticket'])
    rep = requests.post(
        url=msg_url,
        data=bytes(json.dumps(data_dict,ensure_ascii=False),encoding='utf-8')
    )

    print(rep)

    return "发送成功"

9、使用

　　使用发送信息的时候、需要先获取用户当前的UserName，在第一次获取index.html时

 print(init_user_dict)里去网页json解析出来即可使用，注意每次登录的username里的符号都会变化

'User': {
'Uin': 2589030507,
'UserName': '@586d71fe149ae1942bc5bca1f64edd87d385b449850bdc6796ade1a92c9d2933',

10、总结

发送data和json的区别

    关系发送消息：
            data:
                request.post(
                    url='xx',
                    data={'k1':'v1,'k2':'v2'}
                )
                #数据：  POST /  http1.1
....

k1=v1&k2=v2
                
                
                request.post(
                    url='xx',
                    data=json.dumps({'k1':'v1,'k2':'v2'})
                )
                #数据：  POST /  http1.1
....

{'k1':'v1,'k2':'v2'}
                
                request.post(
                    url='xx',
                    data=b'asdfasdf'
                )
                #数据：  POST /  http1.1
....

'asdfasdf'
            json:
                request.post(
                    url='xx',
                    json={'k1':'v1,'k2':'v2'}
                )
                #数据：  POST /  http1.1
Content-type:application/json....

{'k1':'v1,'k2':'v2'}
    
            问题：
                同时：POST请求发数据

                发送数据格式：
                    方式一：

                            url='xx',
                            data={'k1':'v1,'k2':'v2'}
                        )
                        #数据：  POST /  http1.1
Content-type:urlencode-form.......

                        request.POST必然可以获取到值。
                            - content-type: urlencode-form
                            - 数据格式：k1=v1&k2=v2
    
                    方式二：
                        request.post(
                            url='xx',
                            json={'k1':'v1,'k2':'v2'}
                        )
                        #数据：  POST /  http1.1
Content-type:application/json....

{'k1':'v1,'k2':'v2'}
                        request.body 
                            字节 = {'k1':'v1,'k2':'v2'}
