我使用角$ http拦截器来检查ajax请求是否返回401（未验证）。 如果响应是401，原始请求会排队，将显示一个登录表单，登录成功后会重试排队的请求。这已经与$ HTTP工作，并为角拦截的来源是：
define('common.service.security.interceptor', ['angular'], function() {
'use strict';
angular.module('common.service.security.interceptor', ['common.service.security.retryQueue'])
.factory('securityInterceptor', [
'$injector',
'$location',
'securityRetryQueue',
function($injector, $location, securityRetryQueue) {
return function(promise) {
var $http = $injector.get('$http');
// catch the erroneous requests
return promise.then(null, function(originalResponse){
if(originalResponse.status === 401){
promise = securityRetryQueue.pushRetryFn('Unauthorized', function retryRequest(){
return $injector.get('$http')(originalResponse.config);
});
}
return promise;
});
};
}
])
// register the interceptor to the angular http service. method)
.config(['$httpProvider', function($httpProvider) {
$httpProvider.responseInterceptors.push('securityInterceptor');
}]);});
我怎样才能让用这个角度$拦截HTTP请求的微风？
Breeze为文件“Breeze/Adapters/breeze.ajax.angular.js”中的角度$ http服务提供封装。所以，第一个想法是告诉微风使用它：
breeze.config.initializeAdapterInstance("ajax", "angular", true);
调试angular.js，这表明现在的微风实际上使用$ HTTP，但它不执行上述注册拦截器。在$ http内部，有一个阵列“reversedInterceptors”，它包含已注册的拦截器。我将这个数组记录到控制台。如果我使用$ http，这个数组的长度是1（与预期的一样），但是当用微风发出请求时，这个数组是空的。
问题是，我如何使用$ HTTP拦截器和微风请求？
这里是breeze.ajax.angular.js代码，使用setHttp方法适用于我使用HTTP拦截随着微风角阿贾克斯适配器由微风

宾果！ @almaplayer。 'setHttp' FTW。请参阅下面的答案。 – Ward
