小贝子编程

可能的控制器或至少执行两次功能



所以我会遇到此错误："获取http：//localhost：8000/blogs/undefined net :: err_empty_response angular.js：12587。

当我转到我的主要博客页面以及转到博客类别页面时，它会发生。查看我得到的网络选项卡： 1. blog-home.html 200 xhr angular.js 12587 4.6kb 21ms 2.所有200 xhr angular.js 12587 3.0kb 57ms 3.未定义的待处理XHR Angular.JS 12587 3.0KB 57ms 0kb

我去博客类别页面时相同。最终他们失败并踢上述错误。

因此，在此之前，我已经在堆栈上阅读并尝试了：没有运气。也许我错过了一些东西或输入了问题。我完全傻眼了，我觉得这显然超出了我的技能水平。所以这是一堆代码...server.js 

var express = require('express');
var favicon = require('serve-favicon');
var bodyParser = require('body-parser');
var Mailgun = require('mailgun-js');
var path = require('path');
require('colors');
var app = express();
app.use(favicon(path.join(__dirname, 'client/assets/images', '*****')))
app.use(bodyParser.urlencoded({extended:true}));
app.use(bodyParser.json({extended:true}))
app.use(express.static(path.join(__dirname, 'client')));
app.use(express.static("./bower_components"));
//app.all('/*', function(req, res, next) {			    
//    res.sendFile('index.html', { root: 'client'});
//});
require('./server/config/mongoose.js');
var routes = require('./server/config/routes.js');
routes(app);
var api_key = '*********';
var domain = '*********';
var mailgun = require('mailgun-js')({apiKey: api_key, domain: domain});
 
var data = {
  from: '********',
  to: '********',
  subject: 'Hello',
  text: 'Testing some Mailgun awesomness!'
};
 
mailgun.messages().send(data, function (error, body) {
  console.log(body);
});
app.listen(8000, function () {
  console.log("I'm listening...".blue);
})

blogviewController(函数在哪里。再次，我评论了getOneBlog，并且没有发生错误。所以是什么触发了这场火，在单击按钮之前？(

Bridgeman.controller('blogViewController', function($scope, blogFactory, $location, $routeParams){
  console.log("in the blog VIEW controller");
  $scope.blogs = [];
  $scope.one = [];
  blogFactory.getAllBlogs(function(output){
    $scope.blogs = output;
    console.log(output);
  })
  blogFactory.getOneBlog($routeParams.id, function(output){
    $scope.one = output;
    console.log(output);
  })
});

blogfactory(这里没有问题(

Bridgeman.factory('blogFactory', function($http){
  var factory = {};
  factory.submitNewBlog = function(input, callback){
    $http.post('/blogs/new', input).then(function(output){
      console.log("we just added a new blog");
      callback(output.data);
    });
  }
  //factory.submitNewComment = function(input, callback){
  //  $http.post('/comments/new', input).then(function(output){
  //    console.log("we just added a new comment");
  //    callback(output.data);
  //  });
  //}
  factory.getAllBlogs = function(callback){
    $http.get('/blogs/all').then(function(output){
      console.log("we just got all blogs");
      callback(output.data);
    });
  }
  factory.getOneBlog = function(blogID, callback){          //factory.getOneBlog = function(blogID, callback)
    $http.get('/blogs/' + blogID).then(function (output){          //$http.get('blogs/' + blogID).then(function (output){
      console.log(output.data);                             //callback(output.data);
      console.log("we just got one blog");
      callback(output.data);
    });
  }
  return factory;
});

路由(这里有几种不同的样式仅将不同格式绑定以解决此问题(

var users = require('./../controllers/users.js');
var blogs = require('./../controllers/blogs.js');
module.exports = function(app){
	
	app.post('/reg', function(req, res){
	users.reg(req, res);
	});
	app.post('/login', function(req, res){
	users.login(req, res);
	});
	
	app.get('/blogs/all', function(req, res) {
        blogs.getAllBlogs(req, res);
    });
    app.get('/blogs/:id', blogs.getOneBlog); 			//app.get('/blogs/:id', blogs.getOneBlog)       
    
    app.post('/blogs/new', function(req, res) {
        blogs.addBlog(req, res);
    });

		  if(!error)
		    res.send("Your message has been sent");

blogs.js服务器端控制器(这里没有问题...我知道(

var Blog = mongoose.model('Blog');
module.exports = (function() {
    return {

            res.json(b);
          }
        });
      },
      getOneBlog: function(req, res) {
        console.log('Rich band aid');
        if (req.params.id !== 'undefined') {
        console.log('there was an id', req.params.id); 
        Blog.findOne({_id: req.params.id}).exec(function(err, b) {        //({_id: req.params.id}, function(err,b){})

            res.redirect('/blogs/all');
          }
        })
      }
    }
})();

和猫鼬DB(这里没有问题...我知道(

var mongoose = require('mongoose');
// Create the message schema
var BlogSchema = new mongoose.Schema({
	category: {type: String, required: true, minlength: 3, enum:['Security', 'Business', 'SEO', 'AWS', 'Tech in Sports']},
	title: {type: String, required: true, minlength: 3},
	snippet: {type: String, required: true, minlength: 3},
    content: {type: String, required: true, minlength: 3},
    _user: {type: mongoose.Schema.Types.ObjectId, ref: 'User'}    
}, {timestamps: true});
mongoose.model('Blog', BlogSchema);

任何帮助将不胜感激。谢谢

ps ...，是的，当您尝试刷新页面时，我知道Frame-SRC和FONT-SRC的CPS错误。超级烦人。

能够与朋友弄清楚。解决问题是通过将2个函数包装到" if"语句中解决的问题。它可能不是适当的解决方案，但可以很好地工作。

Bridgeman.controller('blogViewController', function($scope, blogFactory, $location, $routeParams){
  console.log("in the blog VIEW controller");
  $scope.blogs = [];
  $scope.one = [];
  if ($routeParams.id) {
    blogFactory.getOneBlog($routeParams.id, function(output) {
    $scope.one = output;
    console.log(output);
    });
  } else {
    blogFactory.getAllBlogs(function(output) {
    $scope.blogs = output;
    console.log(output);
    });
  }  
});
