    后面半小时就是在聊天，可以忽略

    • GET 用于获取数据，比如刷微博，用params
    • POST 用于提交数据，比如登录微博，用data

    微博登入

    打开微博客户端：https://m.weibo.cn/，右击打开”检查“（有的浏览器叫”审查元素“）

    点上图的小图标，可以切换网页版和手机版，手机版相对好爬一点

    点击Preserve log，保留登入信息，接着输入账号密码登入

    关注左侧login，这里面就是我们要爬取的信息

    获取登入网址

    URL_login = "https://passport.weibo.cn/sso/login"

    获取头文件

    一般 referer（请求来源页面）、origin（谁发起的请求）、host（主机名及端口号） 字段也常被用于反爬虫，当我们的爬虫无法正常获取数据时，我们可以将请求头里的这些字段照搬进去试试。

    image 
    headers = {
        'Referer': "https://passport.weibo.cn/signin/login?entry=mweibo&res=wel&wm=3349&r=https://m.weibo.cn/compose/",
        'User-Agent': "Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.131 Mobile Safari/537.36"
        }

    获取登入参数

    params = {
        'username': '******',
        'password': '*******',
        'savestate': '1',
        'r': 'https://m.weibo.cn/compose/',
        'ec': '0',
        'pagerefer': 'https://m.weibo.cn/login?backURL=https%3A%2F%2Fm.weibo.cn%2Fcompose%2F',
        'entry': 'mweibo',
        'wentry': '',
        'loginfrom': '',
        'client_id': '',
        'code': '',
        'qq': '',
        'mainpageflag': '1',
        'hff': '',
        'hfp': ''
        }

    登入微博

    import requests

# 登入微博网址
Request_URL = "https://passport.weibo.cn/sso/login"

# 登入头文件
Request_Headers = {
        'Referer': "https://passport.weibo.cn/signin/login?entry=mweibo&res=wel&wm=3349&r=https://m.weibo.cn/compose/",
        'User-Agent': "Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.131 Mobile Safari/537.36"
        }

# 登入参数
Form_Data = {
        'username': '*****',
        'password': '*****',
        'savestate': '1',
        'r': 'https://m.weibo.cn/compose/',
        'ec': '0',
        'pagerefer': 'https://m.weibo.cn/login?backURL=https%3A%2F%2Fm.weibo.cn%2Fcompose%2F',
        'entry': 'mweibo',
        'wentry': '',
        'loginfrom': '',
        'client_id': '',
        'code': '',
        'qq': '',
        'mainpageflag': '1',
        'hff': '',
        'hfp': ''
        }

res = requests.post(Request_URL, data=Form_Data, headers=Request_Headers)
print(res)

    保留登入状态

    #  使用session保存登入状态
session = requests.Session()
session.headers.update(headers)
res = session.post(URL_login, data=params)

    发微博

    先手动发一条微博，然后看看是哪个网址在响应

    可以在Form Data 中看到发送的详情

    我们可以构造一个评论参数，content是微博的内容，然后我们去找找 st 在哪

    Content_Data = {
  'content': '本条微博由 Python 发送',
  'st': st
}

    st

    鼠标右键点击 显示网页源代码，然后 ctrl + f 搜索请求里的 st 值，我们可以用各种之前学过的方法，把这个数据匹配出来

    或者我们再找找网页，看看有没有这个参数。我们发现，config 里面有这个参数呢~

    Request_Config = session.get('https://m.weibo.cn/api/config')
Config = Request_Config.json()
st = Config['data']['st']

    完整代码

    import requests

# 登入微博网址
RequestURL = "https://passport.weibo.cn/sso/login"

# 登入头文件
RequestHeaders = {
        'Referer': "https://passport.weibo.cn/signin/login?entry=mweibo&res=wel&wm=3349&r=https://m.weibo.cn/compose/",
        'User-Agent': "Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.131 Mobile Safari/537.36"
        }

# 登入参数
FormData = {
        'username': '********',
        'password': '*****',
        'savestate': '1',
        'r': 'https://m.weibo.cn/compose/',

        'wentry': '',
        'loginfrom': '',
        'client_id': '',
        'code': '',
        'qq': '',
        'mainpageflag': '1',
        'hff': '',
        'hfp': ''
        }


LoginSession = requests.Session()
LoginSession.headers.update(RequestHeaders)
Res = LoginSession.post(RequestURL, data=FormData)

# 评论网址
RequestComment = "https://m.weibo.cn/api/statuses/update"

# 获取st值
RequestConfig = LoginSession.get('https://m.weibo.cn/api/config')
Config = RequestConfig.json()
st = Config['data']['st']

# 构造微博参数
DataCompose = {
  'content': '本条微博由 Python 发送',
  'st': st
}

# 发表微博
ResCompose = LoginSession.post('https://m.weibo.cn/api/statuses/update', data=DataCompose)
print(ResCompose.status_code)

    可以加上函数，重写一下这个代码

    import requests

    微博点赞

    获取微博列表

    以扇贝网微博为例（https://m.weibo.cn/u/2139359753）

    def GetList(LoginSession):

            }
    WeiBoListReq = LoginSession.get(URL, params=DataList)
    WeiBoListData = WeiBoListReq.json()
    WeiBoList = WeiBoListData['data']['cards']
    return WeiBoList

    点赞

    def SendHeart(LoginSession,ID):
    st = GetST(LoginSession)
    DataHeart = {

            'attitude': 'heart',

            }

    if ResHeart.status_code == 200:
        print("点赞成功")
    else:
        print("点赞失败")    
    return ResHeart

    批量点赞

    for i in WeiBoList:
    # card_type=9的时候，是一个正常的微博
    if i['card_type'] == 9:
        SendHeart(LoginSession,i['mblog']['id'])

    也可以写成一个函数

    def SendHeartAll(LoginSession):
    WeiBoList = GetList(LoginSession)
    for i in WeiBoList:
        # card_type=9的时候，是一个正常的微博
        if i['card_type'] == 9:
