How to integrate Alipay APP payment into PHP server
Let me share with you an example of PHP server integrating Alipay APP payment. It has a good reference value and I hope it will be helpful to everyone. Let’s take a look together
Alipay payment is divided into many scenarios. Here we only describe the integration of Alipay APP payment function. We encountered particularly big pitfalls during the process, so I will briefly describe the integration process and outline the problems encountered. And solution
Since the company's business is simple and only supports Alipay payment, there is no need to care about refunds, inquiries and other additional functions. Therefore, this article only describes how the server prepares the APP to pull payment orders when using the Alipay payment interface. The general process is as follows
1. Create application and configuration
First, you need to go to the Ant Financial development platform (open.alipay. com) to register the application, obtain the application ID, and configure the application. The configuration here mainly involves signing a contract, generating the application's RSA2 public and private keys, and obtaining the payment public key provided by Alipay. There are prompts in the background of this part of the official website, which is relatively simple.
2. Download the corresponding SDK
Here I am integrating the service in the PHP background, so I downloaded the PHP SDK, address: https:/ /docs.open.alipay.com/54/103419/
3. Prepare an accessible real domain name
4. Case
After the above three steps are completed, we can now configure our own business code
4.1. Organize APP payment Payment order information at the time
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 |

4.2. Asynchronous callback processing after successful Alipay payment
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 |

5. Problems Encountered
##5.1. Keep reporting error 40001=>isv.invalid- signature
In order to find out the reason, I regenerated the application's RSA2 public and private keys several times, but found that it had no effect. Finally, combined with online information, I discovered thatturned out to be the Alipay callback address notifyUrl cannot have '?' and add parameters after ?
##5.2, Alipay asynchronous notification It succeeded, but $_POST was emptyIt also took a while to find this. When I started doing it, I followed Alipay's suggestion and used HTTS to request it. But in this way, the application background keeps notifying that there is no parameter content. Finally, I remembered that because our application uses HTTS two-way authentication, the parameters of Alipay's server callback are empty. Finally, change the callback address to HTTP method, and verify that it passes
If you encounter problems, first check Alipay's document description and the error code explanation provided by Alipay. If it doesn't work, use Baidu or Google, plus you continue to After testing and verification, the problem will definitely be solved in the end
At this point, the payment function of Alipay APP has been completed, and other APP refund, statement and other functions have not been continued. However, according to the official website documents of Alipay and the SDK provided by Alipay , it is only a matter of time before it is integrated into your own application.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

In PHP, exception handling is achieved through the try, catch, finally, and throw keywords. 1) The try block surrounds the code that may throw exceptions; 2) The catch block handles exceptions; 3) Finally block ensures that the code is always executed; 4) throw is used to manually throw exceptions. These mechanisms help improve the robustness and maintainability of your code.

There are four main error types in PHP: 1.Notice: the slightest, will not interrupt the program, such as accessing undefined variables; 2. Warning: serious than Notice, will not terminate the program, such as containing no files; 3. FatalError: the most serious, will terminate the program, such as calling no function; 4. ParseError: syntax error, will prevent the program from being executed, such as forgetting to add the end tag.

In PHP, the difference between include, require, include_once, require_once is: 1) include generates a warning and continues to execute, 2) require generates a fatal error and stops execution, 3) include_once and require_once prevent repeated inclusions. The choice of these functions depends on the importance of the file and whether it is necessary to prevent duplicate inclusion. Rational use can improve the readability and maintainability of the code.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

HTTP request methods include GET, POST, PUT and DELETE, which are used to obtain, submit, update and delete resources respectively. 1. The GET method is used to obtain resources and is suitable for read operations. 2. The POST method is used to submit data and is often used to create new resources. 3. The PUT method is used to update resources and is suitable for complete updates. 4. The DELETE method is used to delete resources and is suitable for deletion operations.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7
