【微信企业号考勤】用什么方法来判断员工在常驻办公室签到签退
新手一枚,在此请教各位前辈一个问题。
最近在做微信企业号的考勤签到签退功能,现在服务器后台已经可以接收到微信用户发送过来的地理位置(经纬度),我的需求是用户只允许在常驻办公室区域(假设办公室很大,几百个平方,在这区域内都可签到签退,区域外则不允许)的地理位置进行签到签退。
获取到用户返回的经纬度后用什么办法判断其是否允许签到签退??
如果采用在数据库存储员工的办公地点地理位置信息然后与其返回的经纬度进行比较的方法判断,可这办公地点很大,地理位置信息如何存储?判断又如何判断?
------解决思路----------------------
首先!目前的地图定位误差也不算太准,好在是在公司,不管是wifi,gps定位还算准确,一般误差在100米之内,姑且最好达到50米。
1:
数据库中存储公司人员半年办公地点所处中心位置经纬度。且以改点为圆心,存储改点到所允许最大办公距离之间的距离,也就是半径了。每次用户签到或则签退,假如A,B两点,A点经度,纬度分别为λA和ΦA,B点的经度、纬度分别为λB和ΦB,d为距离。
利用如下方法:
d=111.12cos{1/[sinΦAsinΦB十 cosΦAcosΦBcos(λB-λA)]}
计算之间距离与数据库中对应用户所允许的距离(半径)比较。在半径发范围内,则允许签到签退。
2:和1类似。问题转化为,已知一个点坐标,求以该点位圆心,半径为r,圆上的所有点的坐标。
2.1:
选取工作人员经常办公地点中心存入数据库,计算改点距离最大允许范围的所有经纬度,存入数据库(不建议,也不科学,数据量大了吃不消。)。
2.2:
。求得是矩形的四个点存入数据库。用户在签到签退的时候比较数据库中的值。
希望这篇文章帮得到你http://digdeeply.org/archives/06152067.html
建议2.2方法。
误差肯定是有的。
给点分吧
------解决思路----------------------
范围小就定个中心点,判断半径呗.
不过有时候不准,不好解决啊
想问的是除了经纬度能搞到网络状态么?
或者提交时候的ip是公司外网/内网ip就可以签到之类

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

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

The reasons why PHP is the preferred technology stack for many websites include its ease of use, strong community support, and widespread use. 1) Easy to learn and use, suitable for beginners. 2) Have a huge developer community and rich resources. 3) Widely used in WordPress, Drupal and other platforms. 4) Integrate tightly with web servers to simplify development deployment.

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.
