        <img style="width: 200px;height: 200px;" src="https://login.weixin.qq.com/qrcode/{{qcode}}" alt="">

    </div>

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 = {}
    soup = BeautifulSoup(text,'html.parser')

5. 信息初始化：

6. 获取所有联系人

            </ul>

        </div>

7. 获取联系人列表

1、

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

contact_list.html

<body>

    <h1>联系人列表</h1>

    <ul>

        {% for user in user_list.MemberList %}

            <li>

                <img style="height: 50px;width: 50px;" src="/get_img?prev={{user.HeadImgUrl}}">

            </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=

    username = request.args.get('username') # @9c4df5e041eb06725a410a3d9d580877e229066895b3e91d44a7af8be37e0e5b

    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() * )

    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':

        },

        'Scene':

    }

    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() * )

    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':

        },

        'Scene':

    }

    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': ,

'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.\r\n....\r\n\r\nk1=v1&k2=v2

                request.post(

                    url='xx',

                    data=json.dumps({'k1':'v1,'k2':'v2'})

                )

                #数据：  POST /  http1.\r\n....\r\n\r\n{'k1':'v1,'k2':'v2'}

                request.post(

                    url='xx',

                    data=b'asdfasdf'

                )

                #数据：  POST /  http1.\r\n....\r\n\r\n'asdfasdf'

            json:

                request.post(

                    url='xx',

                    json={'k1':'v1,'k2':'v2'}

                )

                #数据：  POST /  http1.\r\nContent-type:application/json....\r\n\r\n{'k1':'v1,'k2':'v2'}

            问题：

                同时：POST请求发数据

                django：获取不到值？request.POST 

                发送数据格式：

                    方式一：

                        request.post(

                            url='xx',

                            data={'k1':'v1,'k2':'v2'}

                        )

                        #数据：  POST /  http1.\r\nContent-type:urlencode-form.......\r\n\r\nk1=v1&k2=v2

                        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.\r\nContent-type:application/json....\r\n\r\n{'k1':'v1,'k2':'v2'}

                        request.body

                            字节 = {'k1':'v1,'k2':'v2'}

                            字节转换字符串

                            反序列化字符串 -> 字典 

                        request.POST必然不可以获取到值。

                            - content-type: urlencode-form

                            - 数据格式：k1=v1&k2=v2
