iOS 알 리 페 이,위 챗,은 련 결제 통합 패키지 호출(하)

1.점점 더 많은 app 이 제3자 의 기능 을 추가 합 니 다.app 은 서로 다른 페이지 가 있 지만 똑 같은 결제 방식 을 호출 할 수 있 습 니 다.예 를 들 어 화면 은 다음 과 같 습 니 다.

이 두 페이지 는 모두 제3자 결제 결 제 를 사용 합 니 다.(위 챗,알 리 페 이,은 련)만약 에 모든 페이지 에서 제3자 결제 인터페이스 의 모든 코드 를 직접 호출 하면 적당 하지 않 습 니 다.게다가 하나의 app 은 두 개의 입구 가 아 닐 수도 있 습 니 다.그래서 포장 은 필요 합 니 다.
1.새 모델:----백 엔 드 결제 방식 의 목록 json 되 돌려 주기
