1、安装
npm install vue-resource
2、使用
import VueResource from 'vue-resource';
Vue.use(VueResource);
this.$http.get("http://localhost/test.php").then(
function (res) {
// 处理成功的结果 alert(res.body);
},function (res) {
// 处理失败的结果
}
);
传递数据到后端
this.$http.post("http://localhost/test.php",{name:"zhangsan"},{emulateJSON:true}).then(
function (res) {
// 处理成功的结果
alert(res.body);
},function (res) {
// 处理失败的结果
}
);
有如下方法：
- get(url, [options])
- head(url, [options])
- delete(url, [options])
- jsonp(url, [options])
- post(url, [body], [options])
- put(url, [body], [options])
- patch(url, [body], [options])

resource可以在全局用：Vue.resource，也可以在组件中使用：this.$resource；方法的调用格式：
- resource(url, [params], [actions], [options])
默认调用方法如下所示：
get: {method:'GET'},
save: {method:'POST'},
query: {method:'GET'},
update: {method:'PUT'},
remove: {method:'DELETE'},
delete: {method:'DELETE'}
eg:
var resource =this.$resource('someItem{/id}');
1. resource.get({id:1}).then(response=> {
this.item=response.body;
});
2. resource.save({id:1}, {item:this.item}).then(response=> {
// success callback
}, response=> {
// error callback
});
3.
resource.delete({id:1}).then(response=> {
// success callback
}, response=> {
// error callback
});
还有其他。。，例子可以结合服务网关zuul来实现数据列表实现
mounted : function() {
this.$http.post(contextPath + "/service/getList.json",[]).then(function(response) {
console.log(response);
if (response.ok) {
var body = response.body;
if (body.status === 200) {
this.tableData = body.data;
}
}
}, function() {
console.log(response);
});
}
