この記事で共有した内容は、WeChat のカスタム共有機能の実装コードに関するもので、困っている方はぜひ参考にしてください。情報系のプロジェクトを開発しましたが、営業部門がWeChatを推進する際、共有リンクがWebリンクに直接共有シンボルを加えたもので不格好で不規則だったので、WeChatのカスタマイズ共有機能を勉強しました
事前準備:
1. 認定パブリック アカウント appId、appSecret
2. WeChat 情報を取得するためのさまざまなリンク (このセクションで WeChat カスタム共有 API を探します。アドレス: https://mp.weixin.qq.com/wiki?t=resource/res_main&id) =mp1421141115)
# 获取access_token请求地址
getAccessTokenUrl: https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=%s&secret=%s
#获取accessToken
getAccessTokenOAuthUrl: https://api.weixin.qq.com/sns/oauth2/access_token?appid=%s&secret=%s&code=%s&grant_type=authorization_code
# 获取用户基本信息请求地址
getUserInfoUrl: https://api.weixin.qq.com/sns/userinfo?access_token=%s&openid=%s&lang=zh_CN
#获取code
getCodeUrl: https://open.weixin.qq.com/connect/oauth2/authorize?appid=%s&redirect_uri=%s&response_type=%s&scope=%s&state=%s#wechat_redirect
#获取ticket
