Analysis of the technical principles of the "PH verification" framework in the Java class library

The "PH verification" framework in the Java library is a tool to verify the ID number of mainland China.The framework depends on the verification of ID coding rules stipulated by China's national standard "Citizenship Number" (GBT 2260-2007). In terms of technical principles, the framework mainly uses regular expressions and school test algorithms to verify the effectiveness of the ID number. First, the framework uses a regular expression to verify the input ID number in the basic format.These regular expressions are used to match the different parts of the ID number, such as regional code, birth date, order code and verification code.By matching these parts, you can determine whether the basic format of the ID number meets the requirements. Next, the framework uses the school test algorithm to check each one of the ID number.The verification algorithm mainly depends on the last verification code of the ID number.The verification algorithm will multiply the first 17 digits of the ID number with the fixed weight value and add a sum of the multiplication.Then, the sum of this sum is divided by 11 remaining, and the remaining number is corresponding to a fixed verification code.If the check code of the calculated is equal to the last school code of the ID number, it means that the ID number is valid, otherwise it is invalid. The following is a simple Java code example, which demonstrates how to use the "PH verification" framework to verify the ID number: import com.example.phvalidator.PHValidator; public class Main { public static void main(String[] args) { // The ID number to be verified String idNumber = "110101199001011234"; // Use the static method of the PHVALIDATOR class Validate to verify the ID number boolean isValid = PHValidator.validate(idNumber); if (isValid) { System.out.println ("Valid ID number"); } else { System.out.println ("Identity Card Number Invas"); } } } In the above example, by calling the value method of the PHVALIDATOR class, and passing into the verified ID number to get a Boolean value to represent the validity of the ID number. In short, the "PH verification" framework is a Java class library based on regular expression and verification algorithms, which are used to verify the ID number of mainland China.By using this framework, the validity of the ID number can be easily verified.
