我正在使用http拦截器。当我发出Restangular GET请求时,我确实看到了所有的值。这是我的请求拦截器的代码。
request: function (config) {
// see link below to see value of config
console.log('config', config);
// below returns full url except query string
console.log('location', $location.absUrl());
// $rootScope.cacheData is $cacheFactory
console.log('$rootScope', $rootScope.cacheData);
// only returns {id: "http", size: 3}
console.log('cache info', $rootScope.cacheData.info());
// below returns undefined
console.log('cache get', $rootScope.cacheData.get('http'));
// other codes removed since it's not related
// ........
// ........
// Return the config or wrap it in a promise if blank.
return config || $q.when(config);
},

不幸的是,准备手动捕获的参数不是100%保证它将与缓存的匹配。我注意到cacheFactory检查所请求的确切字符串。因此,如果我们的GET请求的查询参数是age = 12& name = scott然后在我们的http拦截器上,我们通过将名称放在第一位然后将年龄(name = scott& age = 12),cacheFactory赢得&#来另外准备它39;找不到。
所以我试图寻找一个角度服务或工厂,它将返回与我们提出的请求相等的完整URL。我尝试了$ location但它没有提供完整的GET请求。

我刚决定解析配置并从头开始构建它。它工作得很好:))
if ( config.method == 'GET' && (config.url.indexOf('v1/repeters') != -1) ) {
// Prepare the full path
var cachedUrlsLocalStorage;
var absolutePath = '';
_(config.params).keys().sort().each( function(key, index) {
var value = config.params[key];
absolutePath = absolutePath + key + '=' + value + (index < _(config.params).keys().value().length - 1 ? '&' : '');
});
cachedUrlsLocalStorage = JSON.parse(window.localStorage.getItem('cachedUrls'));
if (cachedUrlsLocalStorage) {
var exists = _.findIndex(cachedUrlsLocalStorage, function(cachedData) {
return cachedData.url == config.url + '?' + absolutePath;
});
if (!exists) {
cachedUrlsLocalStorage.push({url : config.url + '?' + absolutePath, timeExecuted : moment(), expiryTime : moment().add(10, 'minutes')});
window.localStorage.setItem('cachedUrls', JSON.stringify( cachedUrlsLocalStorage ));
}
} else {
cachedUrlsLocalStorage = [];
cachedUrlsLocalStorage.push({url : config.url + '?' + absolutePath, timeExecuted : moment(), expiryTime : moment().add(10, 'minutes')});
window.localStorage.setItem('cachedUrls', JSON.stringify( cachedUrlsLocalStorage ));
}
}
