이 글은 주로 asp.net 구현 인터페이스 개발 방법에 대한 자세한 설명입니다.
WeChat 공개 계정에 대해 말하자면, 이 플랫폼을 사용하면 웹사이트나 시스템에 새로운 하이라이트를 추가할 수 있습니다. 공식 API 사용하기 전에 신중하게 문서를 작성하십시오.
.net을 사용하여 구현한 방법:
//WeChat 인터페이스 주소 페이지 코드:
weixin _wx = new weixin();
string postStr = "";
if (Request.HttpMethod.ToLower() == "post")
{
Stream s = System.Web.HttpContext.Current.Request.InputStream;
byte[] b = new byte[s.Length];
s.Read(b, 0, (int)s.Length);
postStr = Encoding.UTF8.GetString(b);
if (!string.IsNullOrEmpty(postStr)) //请求处理
{
_wx.Handle(postStr);
}
}
else
{
_wx.Auth();
}특정 처리 클래스
