1. 서문
저는 최근 위챗 개발을 유난히 싫어하는 사람입니다. 다른 사람이 작성한 일부 WeChat 개발 "프레임워크"를 다운로드했지만 구현이 너무 부풀려져서 역겨웠습니다.
제가 가장 싫어하는 것은 WeChat에서 반환한 xml 메시지를 엔터티 클래스로 조립하는 것입니다. 그래서 요즘은 경량화가 옹호되기 때문에 큰 문제를 피할 수 있는 방법이 없습니다. 엔터티 클래스의 수?
물론 패키징은 상대적으로 복잡합니다. 공식 API를 읽은 후 "프레임워크"를 보면 사람들이 혼란스러워지고 충분히 명확하지 않게 됩니다 .
2. 내 구현 아이디어
내 WeChat SDK(감히 프레임워크라고 부르지는 않음)에서 가장 중요한 것은 두 가지 목표를 달성하는 것입니다.
1 .Lightweight는 엔터티 클래스를 포기하고 Entity를 최대한 적게 선언하며 SDK의 크기를 줄이는 것을 의미합니다.
2. 간단하고 명확합니다. 즉, SDK 클래스 구분이 공식과 일치합니다. API를 한눈에 쉽게 알 수 있도록 하신 의도를 이해합니다.
사실 WeChat을 호출하는 작동 원리는 프레임워크 등을 고안할 필요가 전혀 없으며 자격을 갖춘 프로그래머라면 누구나 할 수 있다고 믿습니다.
우리 서버는 WeChat과 통신하기 위해 GET과 POST만 필요합니다. 이런 관점에서 보면 디자인이 상당히 사용자 친화적입니다. GET은 WeChat 서비스의 확인 및 확인에 연결하는 데 사용되며 POST는 WeChat 서버에서 메시지를 수신한 다음 응답을 조합하여 반환하는 데 사용됩니다.
3. 코드 업로드알았어, 더 이상 말도 안 되는 소리는 하지 마세요.
WeChat 서버 Post는 xml 메시지를 주고 json을 반환하므로 서로 전송해야 합니다. 이렇게 세 가지 유형의 형식이 있습니다. 이는 프레임워크에서 정의한 엔터티 클래스가 많아 프레임워크가 충분히 가볍지 않은 이유이기도 합니다.
첫 번째 목표를 달성하기 위해 .net Framework 4.0의 Dynamic 기능을 주로 사용했고, xml 문자열을 Dynamic Object로 자동 변환하는 DynamicXml.cs 클래스
와DynamicJson.cs를 사용했습니다. json 문자열을 동적 개체로 자동 변환하는 클래스입니다. 열심히 검색한 끝에 드디어 원하는 것을 찾았습니다.
1. 다음은 DynamicXml.cs 클래스이며, 파일 헤더에는 원저작자의 저작권 정보가 포함되어 있습니다.
