Question

我尝试使用Restangular从后端检索JSON对象。

1）这很好用，但我不知道如何处理错误，因为没有回调/保证功能：

meals = restAngular.all('meal').getList({date: selectedDate}).$object;

以下承诺不起作用：

restAngular.all('meal').getList({date: selectedDate}).then(function(newMeals){
    console.log(newMeals);
    meals = newMeals;
});

我在我的＆＃34; newMeals＆＃34;中得到了一个Restangular对象。对象而不是我的Json对象。类似的东西：

addRestangularMethod: function (){var g=arguments,h=a?u:this;
all: function () { [native code] }
allUrl: function () { [native code] }
clone: function () { [native code] }
customDELETE: function () { [native code] }
etc..

如何使用承诺并能够处理潜在错误来获取我的JSON＆＃34;餐食＆＃34;

2）补充问题：自Angularjs 1.2及其更好的新$资源实施以来，Restangular仍然是一个不错的选择吗？

非常感谢

Answer 1

您可以这样做：

restAngular.all('meal').getList({date: selectedDate}).then(function(newMeals){
    console.log(newMeals);
    meals = newMeals;
}, function(response) {
    console.log("Error with status code", response.status);
});

获取简单回复对象

// using .plain() method
restAngular.all('meal').getList({date: selectedDate}).then(function(newMeals) {
    console.log(newMeals); // prints restangular object, ie, your response object with additional methods like get, post, put, remove, clone and many others

    // To get plain response
    meals = newMeals.plain();
    console.log(meals); // prints plain response object
})
.catch(function(response) {
    console.log("Error with status code", response.status);
});

，否则

// you can configure this globally in restangular config by adding below line of code // so that you will get plain response data by default restAngular.setPlainByDefault(true); // and now restAngular.all('meal').getList({date: selectedDate}).then(function(newMeals) { console.log(newMeals); // prints plain object since setPlainByDefault is set to true in restangular config meals = newMeals; }) .catch(function(response) { console.log("Error with status code", response.status); });
