userManager（实训）

路由只是相当于将那些请求区分然后把他跟要传的参数什么的匹配一下，列好，非常清晰，但是很明显，没有具体的方法实现代码。Router关注的是要发送的请求，就是Alamofire.request()括号里面的，但是真的要发送请求，然后把再对返回的数据进行解析什么的还是要用userManager。还是先贴代码！！

其实看了前面写的Alamofire发网络请求的那一章，应该就没什么不明白的了，也应该能看明白Router跟userManager的关系了。其实这里就是把前面说的用Alamofire发送的网络挪过来了，然后发送的请求，以及发送请求的方式，都用Router封装好了。这样的话，等到我们在登录注册界面编写的时候，就不用再写用Alamofire发送各种手机号什么的参数，或者再解析JSON数据了，直接调用userManager里的相应的方法就行了。
