$http({url:'',method:''}).success().error()
简洁写法：
$http.get()
$http.post()
...
注意事项：
①要求返回的数据格式是json格式
②在发起post请求时，如果需要传参
$http.post('url',data),需要设置请求头：
$http.defaults.headers.post = {'Content-Type':'application/x-www-form-urlencoded'};
全局设置请求头：
app.run(function($http){
$http.defaults.headers.post = {'Content-Type':'application/x- www-form-urlencoded'};})
例子：
点击按钮，发起get请求，服务器接收数据返回给客户端，将返回的结果显示出来
发送：name='zhangsan'
返回：json格式字符串
