from weixin . lib . wxcrypt import WXBizDataCrypt

api = WXAPPAPI ( appid = APP_ID ,
                  app_secret = APP_SECRET )
session_info = api . exchange_code_for_session_key ( code = code )

# 获取session_info 后

session_key = session_info . get ( 'session_key' )
crypt = WXBizDataCrypt ( WXAPP_APPID , session_key )

# encrypted_data 包括敏感数据在内的完整用户信息的加密数据
# iv 加密算法的初始向量
# 这两个参数需要js获取
user_info = crypt . decrypt ( encrypted_data , iv )

Using an access token

After obtaining the access token, you can use the token to obtain user information, etc.:

Examples of using WeChat open platform:

 from weixin . client import WeixinAPI

scope = ( "snsapi_login" , )
api = WeixinAPI ( appid = APP_ID ,
                app_secret = APP_SECRET ,
                redirect_uri = REDIRECT_URI )
authorize_url = api . get_authorize_url ( scope = scope )

access_token = api . exchange_code_for_access_token ( code = code )

api = WeixinAPI ( access_token = access_token )

user = api . user ( openid = "openid" )

Examples of using WeChat public platform:

 from weixin . client import WeixinMpAPI

scope = ( "snsapi_base" , )
api = WeixinMpAPI ( appid = APP_ID ,
                  app_secret = APP_SECRET ,
                  redirect_uri = REDIRECT_URI )
authorize_url = api . get_authorize_url ( scope = scope )

access_token = api . exchange_code_for_access_token ( code = code )

api = WeixinMpAPI ( access_token = access_token )

user = api . user ( openid = "openid" )

WeChat payment usage example:

 from weixin . pay import WeixinPay

wxpay = WeixinPay ( appid = 'appid' ,
                  mch_id = 'mchid' ,
                  notify_url = 'url' ,
                  partner_key = 'key' )
                  create_pay_info = {}

# 统一下单
wxpay . unifiedorder ( ** create_pay_info )
# 查询订单
wxapp . order_query ( out_trade_no = 'out_trade_no' )

# 企业付款
wxepay = WeixinEnterprisePay ( appid = 'appid' ,
                             mch_id = 'mchid' ,
                             mch_key = 'mch_key' ,
                             mch_cert = 'mch_cert' ,
                             partner_key = 'key' )

wxepay . transfers ( partner_trade_no ,
                 openid ,
                 amount ,
                 desc = u'结算' )

# 企业付款查询
wxepay_query = WeixinEnterprisePayQuery ( appid = 'appid' ,
                                        mch_id = 'mchid' ,
                                        mch_key = 'mch_key' ,
                                        mch_cert = 'mch_cert' ,
                                        partner_key = 'key' )
wxepay_query . gettransferinfo ( partner_trade_no )
