AngularJS 返回错误统一处理

var app = angular.module('myApp', []);
app.factory('HttpInterceptor', ['$q', HttpInterceptor]);
function HttpInterceptor($q) {
return {
request: function(config){
return config;
},
requestError: function(err){
return $q.reject(err);
},
response: function(res){
return res;
},
responseError: function(err){
if(-1 === err.status) {
// 远程服务器无响应
} else if(500 === err.status) {
// 处理各类自定义错误
} else if(501 === err.status) {
// ...
}else if(401==err.status){

}

return $q.reject(err);
}
}
}

// 添加对应的 Interceptors
app.config(['$httpProvider', function($httpProvider){
$httpProvider.interceptors.push(HttpInterceptor);
}]);
