某丰利用flask在线获取AppRedirctUrl

通过上篇文章知道，二维码登录需要App的微信开发ID和bundleID，某丰的的id为wx222f0c1247113f97, bundleID为com.sf-express.waybillcn
前面参照上一篇文章某朴超市利用flask在线获取refreshToken
主要的点在于某丰的header[‘sytToken’]通过header内value进行了多次md5
很多值都能写死

def get_sytToken(t,b):
    p0=b+"&080R3MAC57J2{A19!$3:WO{I<1N$31BI"
    tmp=md5(deviceId + t + clientVersion + "2NBF+BE4{@P:@X${Q9BAE>{PAK!D:N*^CN" + languageCode + md5(p0) + jsbundle + "&2NBF+BE4{@P:@X${Q9BAE>{PAK!D:N*^")
    sytToken = md5(tmp+"&"+"0HQ%H91K&AA{DH$*XV>XR)VKL:QFE{&%")
    return sytToken

某丰的 login_url为https://ccsp-egmas.sf-express.com/cx-app-member/member/app/weixin/getAccessTokenByCode

jsondata = {
      code": code
  }

主要是header[‘sytToken’]为get_sytToken(timeInterval, json.dumps(jsondata)),timeInterval为字符串13位时间戳
Post请求之后取得mobile和userId
再进行Post请求https://ccsp-egmas.sf-express.com/cx-app-member/member/app/user/universalSign

{
    "needReqTime": "1",
    "memNo": "00000000000000000000000000000000",
    "mobile": mobile,
    "userId": userId,
    "extra": "",
    "name": "mcs-mimp-web.sf-express.com"
}

将结果返回给前端，前端提取sign构建URL

const sign = encodeURIComponent(sign);
const bizCode = encodeURIComponent('{"path":"/up-member/newPoints","linkCode":"","supportShare":"YES","subCategoryCode":"1","from":"","categoryCode":"1"}');
const url = `https://mcs-mimp-web.sf-express.com/mcs-mimp/share/app/activityRedirect?sign=${sign}&source=SFAPP&bizCode=${bizCode}`;

url就是我们需要的
