applepay

ApplePay在中国上线后，就有许多线上app前后脚加入了对其的接入支持，个人比较喜欢的ENJOY也抢在首批接入了ApplePay应用内支付。本文将分享作者的接入经验。 ApplePay是苹果公司推出的一种线上/线下的便捷支付方式，根据TouchId来验证支付卡持卡人身份，ApplePay并不参与资金流动，最终还是让银行完成扣款处理，目前据Apple介绍只配备在iphone6以上和新款的ipad Air2和ipad mini3上，中国地区最低系统要求为IOS9.2，对于一种新支付体验，这门槛的确有点高了。苹果开发文档对ApplePay工作方式的介绍. 线下支付使用NFC POST机只需要与银联联系签约租用即可，我们来介绍线上支付的流程和app应用内接入的方法。 目前的接入方式有两种，一是使用第三方提供商的SDK接入，另一种是让PassKit Framework直接与银联的接口对接，当然网络上还有一些自己使用PassKit PaymentRequest自己生成订单组织信息，直接与Apple对接的Demo，因为我们不可能每家银行跑去签约，大陆的银行也不会给我们开放特许，因此这种方式仅仅能用于测试ApplePay的功能和API尝鲜，并不适用于生产中。 ApplePay官网 上有列出中国目前支持并提供SDK的第三方提供商 使用第三方SDK接入的优点是开发成本比较低

I'm starting an Apple Pay integration project and have been able to wire up a transaction on the device, and use Stripe to authorize the payment. The part I'm actually struggling with is the proper way for the device to test whether Apple Pay is supported? Thus, for older Iphone models I would choose to hide the Apple Pay features, even if they have ios8 or ios9 installed. I can probably check for the device model, and ignore Apply Pay for < Iphone5S. However this gets complicated if I also need to start testing IPad versions, etc. I was wondering if there is a single method somehow to test if

I would be really helpful if anyone provides a solution to know, how do we add the credit/debit card details to Wallet from our App . I have the credit/debit card details for the user and when user tap on Apple Pay option in my App, the Add Card screen in Apple Wallet need to be opened with card data pre-populated. How do we achieve the same. Thanks in advance The good news is that this can be done. What you are looking for is In-App Provisioning of Payment Cards . This is done using the PKAddPaymentPassViewController , which requires the com.apple.developer.payment-pass-provisioning

1. 格式化输出：利用format "{1} {0} {1}".format("hello", "world") # 设置指定位置 'world hello world' 或 %s,%d % str1,int1 * format的四种玩法（python推荐使用format做格式化输出） ```python # 第一种 按位置占位 跟%s原理一致 str1 = 'my name is {}, my age is {}'.format(18,'age') print(str1) # 第二种 按索引占位 str1 = 'my name is {1}, my age is {0}'.format('egon',18) print(str1) # 第三种 指名道姓占位（关键字传参） str1 = 'my name is {name}, my age is {age}'.format(name='egon',age=18) print(str1) #第四种 format简写,两个变量进行拼接时用 name='egon' age=18 str1 = f'my name is {name}, my age is {age}' print(str1) ``` 2. 形参 实参 位置参数 关键字参数 默认参数 形参： def func(arg1,arg2) arg1,arg2即为形参 实参
