做单本小说网站怎么样外贸产品销量排名

一、找到生成二维码链接地址

• 下面是微博APP扫码登录，其他授权APP扫码后期更新！
• 通过F12或者抓包软件Fiddler找到第一个链接地址

loginurl = 'https://login.sina.com.cn/sso/qrcode/image?entry=weibo&size=180&callback=STK_{}'
texturl = session.get(loginurl.format((time.time() * 1000), headers=headers)).text
print(texturl)
#输出texturl = window.STK_16149…… && STK_1614992087527.347({"retcode":20000000,"msg":"succ","data":{"qrid":"2MjNgQt……","image":"\……"}});

• 小编发现image就是二维码图片，qrid就是需要下一步的参数
• 通过筛选和转码获取image、qrid的两个参数进一步访问运行

session = requests.session()
loginurl = 'https://login.sina.com.cn/sso/qrcode/image?entry=weibo&size=180&callback=STK_{}'
texturl = session.get(loginurl.format((time.time() * 1000), headers=headers)).text
#通过筛选获得主要参数
xx = re.search("window.STK_\d+.\d+ && STK_\d+.\d+\(?", texturl)
x = json.loads(texturl.strip().lstrip(xx.group()).rstrip(");"))
qrid = x['data']['qrid']
image = x['data']['image']

• 直接访问打开image二维码图片扫码操作

imageurl = session.get('https:' + image, headers=headers).content
t = showpng(imageurl)
t.start()

二、找到确认二维码链接地址

• 二维码图片链接我们已经找到，接下来进行扫码后的确认链接

qridurl = 'https://login.sina.com.cn/sso/qrcode/check?entry=weibo&qrid={}&callback=STK_{}'

• 发现需要两个变量参数

qrid和callback

• qrid上面我们已经获取，callback就是时间戳

while 1:dateurl = session.get(qridurl.format(qrid,(time.time() * 1000), headers=headers)).text#输出dateurl = window.STK_1614995146615.8608 && STK_1614995146615.8608({"retcode":50114001,"msg":"\u672a\u4f7f\u7528","data":null});xx = re.search("window.STK_\d+.\d+ && STK_\d+.\d+\(?", dateurl)x = json.loads(dateurl.strip().lstrip(xx.group()).rstrip(");"))retcode = x['retcode']if '50114001' in str(retcode):print('二维码未失效，请扫码！')elif '50114002' in str(retcode):print('已扫码，请确认！')elif '50114004' in str(retcode):print('二维码已失效，请重新运行！')elif '20000000' in str(retcode):print('已确认，登录成功！')breakelse:print('其他情况',retcode)time.sleep(5)

• 通过分析retcode的值

50114001：二维码未扫描状态
50114002：二维码已扫描未确认状态
20000000：二维码已确认状态
50114004：二维码已失效

• 登录成功了，可以并没有获取需要的真正cookie值

三、继续寻找相关链接地址获取登录信息

• 二维码确认以后获取了新的参数alt

window.STK_161498904169123 && STK_161498904169123({“retcode”:20000000,“msg”:“succ”,“data”:{“alt”:“ALT-NjE0Njc……”}});

• 通过抓包软件找到下一个链接就是

alturl = 'https://login.sina.com.cn/sso/login.php?entry=weibo&returntype=TEXT&crossdomain=1&cdult=3&domain=weibo.com&alt=ALT-NjE0Njc4MTM……&savestate=30&callback=STK_161498904169125'

name	value
entry	weibo
returntype	TEXT
crossdomain	1
cdult	3
domain	weibo.com
alt	ALT-NjE0Njc4M……
savestate	30
callback	STK_161498904169125

• 将alt带入该链接并进行访问获取新的数据

alt = x['data']['alt']
alturl = 'https://login.sina.com.cn/sso/login.php?entry=weibo&returntype=TEXT&crossdomain=1&cdult=3&domain=weibo.com&alt={}&savestate=30&callback=STK_{}'.format(alt,int(time.time() * 100000))
crossDomainUrlList = session.get(alturl,headers=headers).text
print(crossDomainUrlList)
#输出crossDomainUrlList = STK_161500519933534({"retcode":"0","uid":"61……","nick":"\u7528……","crossDomainUrlList":["https:\/\/……"]});

• 通过访问获取了有用的四个网址

1.https://passport.9797……
2.https://passport.krco……
3.https://passport.weib……
4.https://passport.weibo.com/wbsso……

• 再将上面四个网址逐一访问既可得到想要的最终cookie值

alturl = 'https://login.sina.com.cn/sso/login.php?entry=weibo&returntype=TEXT&crossdomain=1&cdult=3&domain=weibo.com&alt={}&savestate=30&callback=STK_{}'.format(alt,int(time.time() * 100000))
crossDomainUrl = session.get(alturl,headers=headers).text
pp = re.search("STK_\d+\(?", crossDomainUrl)
p = json.loads(crossDomainUrl.strip().lstrip(pp.group()).rstrip(");"))
crossDomainUrlList = p['crossDomainUrlList']
session.get(crossDomainUrlList[0], headers=headers)
session.get(crossDomainUrlList[1]+'&action=login', headers=headers)
session.get(crossDomainUrlList[2], headers=headers)
#session.get(crossDomainUrlList[3], headers=headers)
print(session.cookies)

• 读取第二网址的时候老是报错，最后通过对比小编发现网址后面既然还需要多加“&action=login”最后成功访问读取，获得了最全的cookie

四、最后保存cookies值并进行验证是否有效或登录状态

• 保存cookie和验证cookie就不详细介绍，直接出完整代码可以看懂
