$ resource非常棒,提供了处理Web服务的非常方便的方法。 如果必须在不同的URL上执行GET和POST,该怎么办?
例如,GET网址为http://localhost/pleaseGethere/:id
和POST网址为http://localhost/pleasePosthere
,没有任何参数

使用[actions]的'url'属性覆盖默认网址。
$resource(url, [paramDefaults], [actions], options);
例如:
$resource('http://localhost/pleaseGethere/:id',{},{
getMethod:{
method:'GET',
isArray:true
}
postMethod:{
url:'http://localhost/pleasePosthere',
method:'POST',
isArray:false
}
}
Angular $资源的使用:http://docs.angularjs.org/api/ngResource/service/$resource

您应该能够将URL公开为参数。我能够做到这一点:
$provide.factory('twitterResource', [
'$resource',
function($resource) {
return $resource(
'https://:url/:action',
{
url: 'search.twitter.com',
action: 'search.json',
q: '#ThingsYouSayToYourBestFriend',
callback: 'JSON_CALLBACK'
},
{
get: {
method: 'JSONP'
}
}
);
}
]);
然后,您可以覆盖GET
来电时的网址。
我在真正的简短测试中发现的一个警告是,如果我在URL字符串中包含http://
,它就不起作用了。我没有收到错误消息。它什么也没做。

如果将带有param名称的哈希添加到$ resource调用中:
$resource('localhost/pleaseGethere/:id', {id: '@id'});
然后在调用函数时将:id映射到 id param(这将调用 GET localhost / pleaseGethere / 123 ):
Resource.get({id: 123});
对于POST,您只是不指定 id 参数:
Resource.post({}, {name: "Joe"});
将调用正确的URL,在这种情况下, POST localhost / pleaseGethere (尾部斜杠被ngResource剥离)。

除了Iris Wong的回答,我想举例说明有多种方法和行动的多个参数:
angular
.module('thingApp')
.factory('ThingResource', ['$resource', '$state', returnThing]);
资源:
function returnThing($resource, $state) {
var mainUrl = '/api/stuffs/:stuffId/thing'
var params = {stuffId: '@_id', thingMongoId: '@_id', thingNumber: '@_id'}
return $resource(mainUrl, params, {
'save': {
url: '/api/stuffs/:stuffId/thing/:thingMongoId',
method: 'POST',
interceptor: {
responseError: function(e) {
console.warn('Problem making request to backend: ', e)
$state.go('oops')
}
}
},
'get': {
url: '/api/stuffs/:stuffId/thing/:thingMongoId',
method: 'GET',
interceptor: {
responseError: function(e) {
console.warn('Problem making request to backend: ', e)
$state.go('oops')
}
}
},
'assignThing':{
method: 'POST',
url: '/api/stuffs/:stuffId/thing/assign/:thingNumber'
}
});
}
这提供了3种不同的方法:
// POST to http://currnt_base_url/api/stuffs/:stuffId/thing/:thingMongoId
ThingResource.save({
stuffId:'56c3d1c47fe68be29e0f7652',
thingMongoId: '56c3d1c47fe6agwbe29e0f11111'})
// GET to current http://currnt_base_url/api/stuffs/:stuffId/thing/:thingMongoId
ThingResource.get({
stuffId:'56c3d1c47fe68be29e0f7652',
thingMongoId: '56c3d1c47fe6agwbe29e0f11111'})
// POST to http://currnt_base_url/api/stuffs/:stuffId/thing/assign/:thingNumber
ThingResource.assignThing({
stuffId:'56c3d1c47fe68be29e0f7652',
thingNumber: '999998'})
答案 4 :(得分:1)
按照这种方式:
(function () {
'use strict';
angular
.module("app")
.factory("SomeFactory", SomeFactory);
function SomeFactory($resource) {
var provider = "http://stackoverflow.com/:action/:id";
var params = {"id":"@id"};
var actions = {
"create": {"method": "POST", "params": {"action": "CreateAwesomePost"}},
"read": {"method": "POST", "params": {"action": "ReadSomethingInteresting"}},
"update": {"method": "POST", "params": {"action": "UpdateSomePost"}},
"delete": {"method": "GET", "params": {"action": "DeleteJustForFun"}}
};
return $resource(provider, params, actions);
}
})();
我希望它有所帮助!享受!
