本文介绍了如何使用angularJS拦截器拦截只有特定的HTTP请求?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我知道如何截获所有请求,但我只是想从我的资源截获的请求。
有谁知道如何做到这一点?
services.config(['$ httpProvider',函数($ httpProvider){
$ httpProvider.interceptors.push('myHttpInterceptor');
}]);services.factory(userPurchased功能($资源){
返回$资源(/ API /用户/购买/:动作/:项,
{},
{
名单:{方法:GET,则params:{行动:'名单'},IsArray的:假},
保存:{方法:把',则params:{项目:@item'}},
删除:{方法:删除,则params:{项目:@item'}},
}
);
});services.factory('myHttpInterceptor',函数($ Q $ rootScope){
// $ rootScope.showSpinner = FALSE;
返回{ 回应:功能(响应){
$ rootScope.showSpinner = FALSE;
//做事情成功
的console.log(成功);
的console.log('状态',response.status);
//返回响应;
返回响应|| $ q.when(响应);
}, responseError:功能(响应){
//做一些错误
$ rootScope.showSpinner = TRUE;
的console.log(失败);
的console.log('状态',response.status)
//返回响应;
返回$ q.reject(响应);
}
};
});
解决方案
如果您想截取从特定的资源只能请求,您可以使用<$可选拦截
属性C $ C> $请求的行动。角的文档(用法>动作)
的JavaScript
angular.module('应用',['ngResource'])。
工厂('resourceInterceptor',函数(){
返回{
回应:功能(响应){
的console.log('响应拦截:',响应);
}
}
})。
工厂('resourceService',['$资源','resourceInterceptor',函数($资源,resourceInterceptor){
返回$资源(:名称,
{},
{
名单:{方法:GET,IsArray的:假的,拦截器:resourceInterceptor}
}
);
}])。
运行(['resourceService','$ HTTP',函数(resourceService,$ HTTP){
resourceService.list({名称:'list.json'}); //&LT; =截获
$ http.get('list.json'); //&LT; =不拦截
}]);

I know how to intercept ALL requests, but I only want to intercept requests from my resources.
Does anyone know how to do this?
services.config(['$httpProvider',function($httpProvider) {
$httpProvider.interceptors.push('myHttpInterceptor');
}]);
services.factory("userPurchased", function ($resource) {
return $resource("/api/user/purchases/:action/:item",
{},
{
'list': {method: 'GET', params: {action: 'list'}, isArray: false},
'save': {method: 'PUT', params: {item: '@item'}},
'remove': {method: 'DELETE', params: {item: '@item'}},
}
);
});
services.factory('myHttpInterceptor', function($q,$rootScope) {
// $rootScope.showSpinner = false;
return {
response: function(response) {
$rootScope.showSpinner = false;
// do something on success
console.log('success');
console.log('status', response.status);
//return response;
return response || $q.when(response);
},
responseError: function(response) {
// do something on error
$rootScope.showSpinner = true;
console.log('failure');
console.log('status', response.status)
//return response;
return $q.reject(response);
}
};
});
解决方案
If you want to intercept only requests from specific resources, you can use optional interceptor
property of $request
action. Angular's documentation see here (Usage>actions)
JavaScript
angular.module('app', ['ngResource']).
factory('resourceInterceptor', function() {
return {
response: function(response) {
console.log('response intercepted: ', response);
}
}
}).
factory('resourceService', ['$resource', 'resourceInterceptor', function($resource, resourceInterceptor) {
return $resource(":name",
{},
{
'list': {method: 'GET', isArray: false, interceptor: resourceInterceptor}
}
);
}]).
run(['resourceService', '$http', function(resourceService, $http) {
resourceService.list({name: 'list.json'}); // <= intercepted
$http.get('list.json'); // <= not intercepted
}]);
