我在Angularjs和MongoDB中創建新的m我需要從MongoDB發送HTTP請求以用於自動完成角度材質,當我發送到git hub API時它完美地工作,但對於我的數據庫, '不能讀取屬性 '' 的未定義' 我控制器長度客戶端Angularjs http獲取請求返回'長度'錯誤
/*jslint latedef:false*/
(function() {
'use strict';
angular
.module('clientApp')
.controller('CarnetCtrl', function($http){
this.querySearch = function(query){
//for this link work "https://api.github.com/search/users"
return$http.get("http://localhost:3000/carnet/export_countries/", {
params: {
q: query
}
}).then(function(response){
return response.data.items;
});
};
});
})();
我控制我的MongoDB
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var Q = require('q'); // We can now use promises!
//Create Schema
var CarnetExportCountriesSchema = new Schema({
CarnetExportCountriesSchema.statics.getCarnetExportCountries = function(Country_Name_EN) {
var deferred = Q.defer();
this.findOne({Country_Name_EN: Country_Name_EN}, function(error, CarnetExportCountries){
if (error) {
deferred.reject(new Error(error));
}
else {
deferred.resolve(manufacturers);
}
});
return deferred.promise;
}
CarnetExportCountriesSchema);
module.exports = CarnetExportCountriesSchema;
和index.js服務器端:
//Add Middleware necessary for REST API's
app.use(bodyParser.urlencoded({extended: true}));
app.use(bodyParser.json());
app.use(bodyParser.json({type:'application/vnd.api+json'}));
app.use(methodOverride('X-HTTP-Method-Override'));
//CROS Support
app.use(function(req,res,next){
res.header('Access-Control-Allow-Origin','*');
res.header('Access-Control-Allow-Methods','GET,PUT,POST,DELETE');
res.header('Access-Control-Allow-Headers','Content-Type');
res.header('("Content-Length", ""+json.length());');
next();
});
我app.js
.config(function (
$routeProvider,
RestangularProvider
) {
RestangularProvider.setBaseUrl('http://localhost:3000');
$routeProvider
.when('/main', {
templateUrl: 'views/main.html',
controller: 'MainCtrl',
controllerAs: 'main'
})
我的錯誤:

請幫我在這件事上我搜索和閱讀1周左右,但解決不了這個問題
您如何期待任何人在此混亂中找到它?你需要把你的代碼燒寫成一個簡潔的例子來重現問題。 –
對不起我的混亂我試圖減少一部分代碼 –
