访问标题数据和处理错误codeS里角的http请求 [英] Accessing header data and treating the error codes in Angular http requests

问题描述

这是我如何处理我的角路由。我有一对夫妇，所有关于每条路线所需的数据存储文件和我遍历这样的数据。 html的请求装载模板和.action的AJAX请求。

我需要做的就是把所有的所在服务器不成功（300，400，500等）的案件。我GOOGLE了所有我想找到相关的一些信息吧，但似乎没有足够的相关或清除。究竟如何做我访问请求的报头数据？

  Application.config（['$ routeProvider'，'$ interpolateProvider'，'$ httpProvider'，    功能（$ routeProvider，$ interpolateProvider，$ httpProvider）
    {        $ interpolateProvider.startSymbol（'＆LT;％'）;
        $ interpolateProvider.endSymbol（'％GT;'）;        对于（VAR I = 0; I＆LT; applicationRoutes.length;我++）{            如果（applicationRoutes [I] .hasInitialData）
            {
                $ routeProvider.when（'/'+ applicationRoutes [I]。路径+的.html'，{                    templateUrl：applicationRoutes [I]。路径+的.html'，
                    控制器：applicationRoutes [I] .controller +'为'+ applicationRoutes [I] .controllerAlias​​，
                    解析：{
                        initData：'初始化'，'$路线'，函数（初始化，$路线）
                        {
                            //console.log($route.current.$$route）;
                            返回Initialize.serverData（'/'+ $ route.current $$ route.pathBase）;
                        }]
                    }，
                    pathBase：applicationRoutes [I]。路径                }）否则（'/ 404'）。
            }
            其他
            {
                $ routeProvider.when（'/'+ applicationRoutes [I]。路径+的.html'，{                    templateUrl：applicationRoutes [I]。路径+的.html'，
                    控制器：applicationRoutes [I] .controller +'为'+ applicationRoutes [I] .controllerAlias​​，
                    pathBase：applicationRoutes [I]。路径                }）否则（'/ 404'）。            }        }        $ httpProvider.defaults.headers.common [X-要求，以] ='XMLHtt prequest';    }]）;
 

解决方案

我看不到你的服务器调用，但假设你已经推出了一个服务来调用端点与$ HTTP记住，你可以使用故障处理程序作为第二个参数承诺的那么

  $ HTTP（REQ）。然后（函数（）{...}，函数（）{...}）;
 

这意味着你可以做到这一点。

  $ HTTP（REQ）。然后（功能（someData）{/ *这是成功的* /}函数（原因）{/ *的原因持有它faild的原因， reason.data等* /}）;
 

This is how I handle my routing in Angular. I have a couple of files where all the needed data about each route is stored and I iterate over the data like this. .html requests are for loading templates and .action for AJAX requests.

What I need to do is treat all the cases where the server doesn't succeed (300, 400, 500 etc). I googled all I thought relevant found some info about it but nothing seems relevant or clear enough. How exactly do I access the header data of a request?

Application.config(['$routeProvider', '$interpolateProvider', '$httpProvider',

    function($routeProvider, $interpolateProvider, $httpProvider) 
    {

        $interpolateProvider.startSymbol('<%');
        $interpolateProvider.endSymbol('%>');

        for (var i=0; i < applicationRoutes.length; i++) {

            if (applicationRoutes[i].hasInitialData)
            {
                $routeProvider.when('/' + applicationRoutes[i].path + '.html', {

                    templateUrl: applicationRoutes[i].path + '.html',
                    controller: applicationRoutes[i].controller + ' as ' + applicationRoutes[i].controllerAlias,
                    resolve: {
                        initData : ['Initialize', '$route', function(Initialize, $route)
                        {
                            //console.log($route.current.$$route);
                            return Initialize.serverData('/' + $route.current.$$route.pathBase);
                        }]
                    },
                    pathBase: applicationRoutes[i].path

                }).otherwise('/404');
            }
            else
            {
                $routeProvider.when('/' + applicationRoutes[i].path + '.html', {

                    templateUrl: applicationRoutes[i].path + '.html',
                    controller: applicationRoutes[i].controller + ' as ' + applicationRoutes[i].controllerAlias,
                    pathBase: applicationRoutes[i].path

                }).otherwise('/404');

            }

        }

        $httpProvider.defaults.headers.common["X-Requested-With"] = 'XMLHttpRequest';

    }

]);

解决方案

I cant see your server calls, but assuming you have rolled up a Service to call the endpoints with $http remember you can use a fail handler as the second parameter of the promise so

$http(req).then(function(){...}, function(){...});

meaning you can do this

    $http(req).then(function(someData){/*This is the success*/},function(reason){/*the reason holds the reason it faild, reason.data etc */});
