百度地图经纬度转换到腾讯地图/Google 对应的经纬度_PHP
实现目的:将百度地图经纬度 转换到 腾讯地图/Google 对应的经纬度.
方法1:使用代码进行转换
存在的问题:转换之后误差大,基本不可用
public static void Convert_BD09_To_GCJ02(double lat, double lng) { double x_pi = Math. PI * 3000.0 / 180.0; double x = lng - 0.0065, y = lat - 0.006; double z = Math. sqrt(x * x + y * y) - 0.00002 * Math.sin(y * x_pi); double theta = Math.atan2(y, x) - 0.000003 * Math.cos(x * x_pi); lng = z * Math. cos(theta ); lat = z * Math. sin(theta ); System. out.println(lng); System. out.println(lat); }
方法2:
该网站提供转换服务,坐标较为准确,可用,后台调用没有仔细研究

方法3:
使用腾讯地图,详见1.html
腾讯地图老版的地址:http://api.map.soso.com/doc_v2/example.html?sample-convertor-library#12map
最新的地址:http://lbs.qq.com/javascript_v2/doc/convertor.html
直接调用的地址,points=经纬度,传入百度的即可:
http://apic.map.qq.com/translate/?type=3&points=114.041993,22.667204&output=jsonp&pf=jsapi&cb=qq.maps.__svcbi1x9al56.cbi1x9al9l0

总结:
由于腾讯的经纬度和google经纬度是同一个坐标系,百度经纬度为自己的体系,目前网上搜索到的算法代码,都不是十分精确,所以建议使用地图开发方提供的Api进行转换.

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,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
