微信支付小吐槽

AI助手支持GPT4.0

The applet calls the payment API to have a variable name with a keyword, which is not very good. In Java, the attribute name cannot be package, so it is embarrassing for me to transfer MD5 to the front end, because I convert the Java object into an XML string, and then MD5 signs, package cannot be used as the attribute name.... Make complaints.. No wonder there is no Java SDK
