开发微信支付的一点心得
由于使用了别人封装的微信公众平台SDK http://www.cnblogs.com/x3d/p/3740454.html ,所以省去了完整理解开发手册的时间。
微信支付,即便交了保证金,你还是处理测试阶段,不能正式发布。必须到你通过程序测试提交订单、发货通知等数据到微信的系统中,才能申请发布。
然后,因为在微信中是通过JS方式调用API,必须在微信后台设置支付授权目录,而且要到二级三级目录下去,这对于使用MVC框架来说,是个小问题。
使用MVC,在开发环境,url往往是native url格式,不能保证一定是带有路径/的形式
所以,比较可靠的方式,是创建实体的子文件夹,这样的化,在系统整体url方面,需要进行一些改造。
另外,最后一步,js调用时,对于 https://github.com/dodgepudding/wechat-php-sdk 这里提供的js库,在调用时,必须确保在页面加载完后触发,即WeixinJSBridgeReady的状态,因为这时才能与微信浏览器提供jsbridge进行通讯。

具体可看微擎中的相关代码。

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

Troubleshooting and solutions to the company's security software that causes some applications to not function properly. Many companies will deploy security software in order to ensure internal network security. ...

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

Golang is better than Python in terms of performance and scalability. 1) Golang's compilation-type characteristics and efficient concurrency model make it perform well in high concurrency scenarios. 2) Python, as an interpreted language, executes slowly, but can optimize performance through tools such as Cython.

Python is easier to learn and use, while C is more powerful but complex. 1. Python syntax is concise and suitable for beginners. Dynamic typing and automatic memory management make it easy to use, but may cause runtime errors. 2.C provides low-level control and advanced features, suitable for high-performance applications, but has a high learning threshold and requires manual memory and type safety management.

Python is better than C in development efficiency, but C is higher in execution performance. 1. Python's concise syntax and rich libraries improve development efficiency. 2.C's compilation-type characteristics and hardware control improve execution performance. When making a choice, you need to weigh the development speed and execution efficiency based on project needs.
