Angular JS $ http请求到webservice

Question

我想做一个AngularJS $ http请求函数，它将从服务器端调用此方法（使用JAX-RS Jersey），此方法为参数使用JSON并返回JSON作为结果，

@Path("/login") 
@POST 
@Consumes(value = MediaType.APPLICATION_JSON) 
@Produces(value = MediaType.APPLICATION_JSON) 
public Response login(User user) { 
    UserDao ud = new UserDao(); 
    User dariDB = ud.login(user.getUsername(), user.getPassword()); 
    dariDB.setPassword(""); 
    return Response.ok(dariDB) 
      .header("Access-Control-Allow-Origin", "*") 
      .header("Access-Control-Allow-Headers", "origin, content-type, accept, authorization") 
      .header("Access-Control-Allow-Credentials", "true") 
      .header("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS, HEAD") 
      .header("Access-Control-Max-Age", "1209600") 
      .build(); 
} 

你能帮助我在AngularJS假设Web服务的URL给了个例子，$http请求功能是“http://localhost:8084/iec3/rest/user/login”？

您可以对服务器的请求，像下面的代码片段：

$http({ 
     method: 'POST', 
     url: 'http://localhost:8084/iec3/rest/user/login' 
     data: user 
    }) 

控制器A完整的例子如下：

$scope.login = function() { 
    $http({ 
     method: 'POST', 
     url: 'http://localhost:8084/iec3/rest/user/login' 
     data: user 
    }).then(function(response) { 
     console.log(response); 
    }, function(error) { 
     console.log(error); 
    }); 
};
