angularjs $http调用接口的方式

angularjs $http调用接口的方式：

$http.get("/merchantmall/merchant.json")
    .success(function(data, status, headers, config) {
        console.log(arguments);
    })
    .error(function(data, status, headers, config) {
        console.log(arguments);
    })

$http({method:"GET", url: "/merchantmall/merchant.json"})
    .success(function(data, status, headers, config) {
        console.log(arguments);
    })
    .error(function(data, status, headers, config) {
        console.log(arguments);
    })

var promise = $http({method: 'GET', url: '/api/users.json'});
promise.then(function(resp) {
    console.log(resp);
}, function(resp) {
    console.log(resp);
});

var promise = $http({
    method: 'GET',
    url: '/api/users.json'
});
promise.success(function(data, status, headers, config) {
    console.log(arguments);
});
promise.error(function(data, status, headers, config) {
    console.log(arguments);
});
