规划驾车路线和途径点及判断车辆路线偏移

2020-02-24 18:48:34

参考地址规划驾车路线和途径点及判断车辆路线偏移

仅供参考，我还是推荐用矩形判断，嘿嘿。

star: 项目需求需要利用百度地图构建路线并支持设置途径点，以及可以实时监控车辆是否偏移路线；两种方案。

写了比较完整的注释了，替换ak可直接看效果，规划驾车路线和途径点及判断车辆路线偏移源码：

npm设置和取消代理的方法
有时候是设置了全局代理对npm并不生效，不如直接给npm设置代理，至少在mac电脑我是有这种感觉的。

node开发邮件系统总结
因为multipart这种形式比较复杂，因此要利用boundary分割符，将邮件体分割成不同段来进行解析，boundary分为父段和子段，父段一般出现0次或1次，出现在末尾，每个子段中也有content-type和boundary，需要在进行解析，如果遇到i,iii里面的情况可直接解析，如果遇到ii中的情况，再按ii中的步骤进行解析

email-templates + mjml 发送邮件
mjml 是一个很不错的响应式邮件html 内容标签库，email-templates 是一个灵活强大的邮件发送框架，两者集成起来我们可以设计灵活强大的邮件发送系统，以下是一个简单的集成使用，实际使用还有好多地方需要完善

响应式邮件的编写插件介绍mjml
以前做项目碰到发邮件的需求，邮件模板的编辑就是一件头疼的事。因为虽说邮件是支持 HTML 的，但是确是 HTML 子集程度的支持，所以存在必须通过 <table> 排版的恶心之处，还有很多兼容性的坑。本质上是各家邮件商的标准有差异吧。

nodejs队列实现amqplib,rabbitmq
其中StartConsumer 会在项目启动时启动，在整个生命周期中一直保持监听状态，在程序结束时mq的链接关闭。需要注意的是 noAck 这个参数，当为false是表示消息出队后不会自动删除，如果设置成true,则无论消息处理成功与否此消息会被删除。注意到在消息不成功是，调用了ch.nack(msg))，此方法是将消息重新入队。

RabbitMQ详解
当前市面上mq的产品很多，比如RabbitMQ、Kafka、ActiveMQ、ZeroMQ和阿里巴巴捐献给Apache的RocketMQ。甚至连redis这种NoSQL都支持MQ的功能。 ActiveMQ ActiveMQ是apache出品，最流行的，能力强劲的开源消息总线，并且它一个完全支持JMS规范的消息中间件。其丰富的API、多种集群构建模式使得它成为业界老牌消息中间件，在中小型企业中应用广泛。

nodejs用redis实现队列操作
其实nodejs实现队列的方式又很多中，也有很多开源的插件和队列数据库可以使用，但是呢，如果我们一个简单的项目，完全可以使用redis来实现队列，这样再不增加技术难度的同事，我们也就可以完美的实现一个队列
