각 POST 요청에 대해 개발자는 메시지에 응답하기 위해 응답 패키지(Get)에 특정 XML 구조를 반환합니다(이제 응답 텍스트, 사진, 그래픽, 음성, 비디오, 음악 지원). 사진 등 멀티미디어 메시지에 답장을 보내실 때에는 미리 위챗 서버에 멀티미디어 파일을 업로드해주셔야 인증된 서비스 계정만 지원됩니다.
오늘은 다음 세 가지에 대해 이야기하겠습니다.
1. 답글 팔로우
2. 자동 답글
3. 키워드 답글
1, 답글 팔로우, 자동 기본 답글
소위 팔로우 답글은 공식 계정을 찾았을 때 팔로우 버튼을 클릭한 후 WeChat이 사용자에게 반환하는 정보입니다.
자동 기본 회신은 특별한 처리가 없는 경우 어떤 메시지를 보내든 기본적으로 시스템에서 회신하는 메시지입니다.
WeChat에서 정보를 주고받는 것은 모두 XML 형식이며, 이는 개발 문서에 구체적으로 설명되어 있습니다. 이제 WeChat 정보의 처리 및 응답을 구현하는 방법에 대해 이야기하겠습니다.
1. 먼저 미리 설정된 답변 정보를 데이터베이스 테이블
CREATE TABLE [dbo].[w_reply](
[reply_id] [int] IDENTITY(1,1) NOT NULL,
[reply_text] [varchar](max) NULL,
[reply_type] [varchar](50) NULL,
[article_id] [int] NULL,
[wechat_id] [int] NULL,
[reply_fangshi] [int] NULL,
CONSTRAINT [PK_w_reply] PRIMARY KEY CLUSTERED
(
[reply_id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GOwechatapi.aspx 페이지에 저장하고 다음 정보를 처리합니다.
2. WeChat에서 보낸 정보를 받습니다
