WeChat AppletWeChat DevelopmentWeChat cash red envelope interface implements sample code sharing for red envelope issuance
WeChat cash red envelope interface implements red envelope issuance:
1: Process: [
Process: WeChat users access the red envelope activity page--"The backend determines whether it is accessed by WeChat
[No: Prompt to use WeChat to open the connection, Yes: Prompt the user whether to authorize permission, obtain their user information [openID and other information]]--》
Enter the red envelope activity page--- 》The user clicks to receive the red envelope [Judge whether the red envelope has been received] Yes: [Prompt that the red envelope has been received] No
--》The back-end program calls the interface to issue the red envelope
--》WeChat user in Receive a red envelope in WeChat
--》Open the red envelope
--》The amount of the red envelope will be added to the wallet change
--》Complete the distribution of the red envelope.
】
2: To implement the WeChat cash red envelope interface to issue red envelopes, the following conditions must first be met:
1. The WeChat public account used to issue red envelopes must be of service type
2. After logging in to the official website of the WeChat official platform, on the public platform backend management page - Developer Center page,
click the "Modify Configuration" button and fill in the server address (URL), Token and EncodingAESKey ,
where URL is the interface URL used by developers to receive WeChat messages and events. Token can be filled in arbitrarily by the developer, and
is used to generate a signature (the Token will be compared with the Token contained in the interface URL to verify security).
EncodingAESKey is manually filled in by the developer or randomly generated, and will be used as the message body encryption and decryption key.
3. Obtain access_token: Official accounts can use AppID and AppSecret to call this interface to obtain access_token.
[AppID and AppSecret can be obtained from the official website of WeChat public platform - Developer Center page (you need to have become a developer, and the account has no abnormal status). 】
4. The WeChat public account must open a "webpage authorization interface" for users to obtain basic user information [especially openID, which is used when sending red envelopes]
5. The "WeChat payment" of the WeChat public account "Merchant number" in " To activate WeChat payment [the amount of red envelopes will be deducted from the payment account], open the "cash red envelope" interface [call this interface to issue red envelopes].
6. Log in to “Merchant Account” [the merchant account assigned by WeChat official account. There are instructions in Chapter 5] In "API Security", download the PHP version of the certificate [.pem format]
If the above description is not clear, please check the WeChat Developer Documentation which has detailed flash sales.
Part of the code is as follows [please see the attachment for the rest]:

微信文件多久过期Nov 21, 2022 pm 02:12 PM微信文件的过期时间需要根据情况来判断：1、如果发送的文件没有打开过，则在72小时以后微信系统会自动清理掉，即过了三天文件就会过期；2、如果已经查看了微信文件，但是并没有下载（当然已经下载的文件也是一样的），那么文件是可以保留180天的，在这180天以内随时都可以去下载。
微信拉黑和删除有什么区别Oct 18, 2022 am 11:29 AM区别：1、拉黑后对话框从主页消失，但是聊天记录还在；删除后聊天记录全部消失不见了。2、拉黑后还能发给他，但是收不到他的消息；删除后不能发信息了。3、拉黑后双方都不可见彼此的朋友圈；删除对方以后，你看不到对方的朋友圈了，对方是否能看到你的，取决于设置（允许陌生人查看十张照片）与否，如果设置则可以看到朋友圈。
支持微信付款的购物平台有哪些Nov 02, 2022 pm 02:44 PM支持微信付款的购物平台有：1、京东，是中国的综合网络零售商；2、唯品会，是一家在线销售品牌折扣商品的互联网公司；3、拼多多，是社交新电商领导者，更懂消费者的购物平台；4、京喜，是京东旗下生活消费商城；5、蘑菇街，一个电子商务网站；6、聚美优品，是一家以销售化妆品为主的时尚购物网站；7、微店，是一个云推广电子商务平台；8、考拉海购，是一个跨境海淘业务为主的会员电商平台。
微信怎么查看ip地址May 31, 2023 am 09:16 AM微信查看ip地址的方法：1、登录电脑版微信，右键点击屏幕下方的任务栏，点击“任务管理器”；2、弹出任务管理器时，点击左下角的“详细信息”；3、任务管理器进入“性能”选项，点击“打开资源监视器”；4、选择“网络”，勾选微信进程“Wechat.exe”；5、点击下面的“TCP连接”即可监视微信网络IP相关情况，发送消息得到回复就会显示他人的IP地址。
微信可以绑别人的银行卡号么Mar 14, 2023 pm 04:53 PM可以。未经过实名认证的微信号，可以绑定他人的银行卡，但在绑定过程中需要提供银行卡的开户人姓名、开户行地址、开户时预留的联系方式及银行卡支付密码；已通过实名认证的微信号，无法绑定他人银行卡，只能添加使用自己身份证办理的银行卡。
一个身份证只能绑定一个微信吗Mar 02, 2023 pm 01:50 PM不是，一个身份证能绑定5个微信。按照微信当前规定，一个身份证可以实名认证5个微信号；如果已经实名认证了5个微信账号，但是还想要继续实名，就要把已经实名认证的一些不用的微信号清除以后，才可以再实名认证新的微信号。
财付通是微信还是支付宝Oct 18, 2022 pm 02:35 PM财付通是微信，是腾讯公司旗下的第三方支付平台，其核心业务是协助在互联网上进行交易的双方完成支付和收款，其使用方式是：1、进行账户注册及登录；2、进行账户充值；3、根据需求设置快捷支付；4、通过打开微信支付或QQ钱包查询交易账单。
电脑微信打字为什么打一个少一个Mar 28, 2023 pm 03:43 PM电脑微信打字打一个少一个是因为开启了改写状态，其解决办法：1、打开电脑微信；2、在微信聊天窗口输入对话文字内容；3、找到并按下键盘上的Insert键即可正常输入文字内容。
