vue处理get/post的http请求的实例

// 基于全局Vue对象使用http
Vue.http.get('/someUrl', [options]).then(successCallback, errorCallback);

// 在一个Vue实例内使用$http
this.$http.get('/someUrl', [options]).then(successCallback, errorCallback);

//不带参数的get请求
this.$http.get('/someUrl').then(function(res){
    console.log('请求成功处理');   
},function(res){
    console.log('请求失败处理');
});

//需要传递数据的get请求
this.$http.get('/someUrl',{param:jsonData}).then(function(res){
    console.log('请求成功处理');   
},function(res){
    console.log('请求失败处理');
});

//ES6的Lambda写法
this.$http.get('/someUrl', [options]).then((response) => {
	console.log('请求成功处理');
}, (response) => {
	console.log('请求失败处理');
});

// 基于全局Vue对象使用http
Vue.http.post('/someUrl', [body], [options]).then(successCallback, errorCallback);

// 在一个Vue实例内使用$http
this.$http.post('/someUrl', [body], [options]).then(successCallback, errorCallback);

this.$http.post('/try/ajax/demo_test_post.php',{name:"菜鸟教程",url:"http://www.runoob.com"},{emulateJSON:true}).then(function(res){
    	document.write(res.body);    
	},function(res){
     	console.log(res.status);
	});

get: {method: 'GET'},
save: {method: 'POST'},
query: {method: 'GET'},
update: {method: 'PUT'},
remove: {method: 'DELETE'},
delete: {method: 'DELETE'}

//全局访问
Vue.resource
//实例访问
this.$resource

//使用一个局部变量来接受this
var vm = this;
this.$resource('apiUrl').get().then((response) => {
	console.log("调用成功");
	})
	.catch(function(response) {
	console.log("调用失败");
	})
}

//使用一个局部变量来接受this
var vm = this;
this.$resource('apiUrl').save('apiUrl',Target).then((response) => {
	console.log("调用成功");
	})
	.catch(function(response) {
	console.log("调用失败");
	})
}

//Lambda函数写法
Vue.http.interceptors.push((request, next) => {
		// ...
		// 请求发送前的处理逻辑
		// ...
	next((response) => {
		// ...
		// 请求发送后的处理逻辑
		// ...
		// 根据请求的状态，response参数会返回给successCallback或errorCallback
		return response
	})
})
//普通写法
Vue.http.interceptors.push(function(request, next) {
	// ...
	// 请求发送前的处理逻辑
	// ...
	next(function(response) {
		// ...
		// 请求发送后的处理逻辑
		// ...
		// 根据请求的状态，response参数会返回给successCallback或errorCallback
		return response
	})
})
