angularjs - angularjs中的多个查询字符串参数

Question

我正在努力传递和读取路由中的多个查询字符串参数。

$routeProvider.when("/joboffers:keywords:location", {
    controller: "jobOffersController",
    templateUrl: "/App/Views/JobOffer/All.html"
});

这是搜索页面:

$scope.searchJobOffer = function () {
    var vm = $scope.jobOfferSearchViewModel;
    var path = "/joboffers?keywords=" +( vm.keywords || "") + "&location=" + (vm.location || "");
    $location.path(path);
}

这是JobOffersController:

'use strict';
app.controller('jobOffersController', ['$scope', '$routeParams', 'jobOfferService', function ($scope, $routeParams, jobOfferService) {
    $scope.jobOffers = [];

    function init() {
        var keywords = $routeParams.keywords;
        var location = $routeParams.location;
    }

    init();
}]);

读取$ routeParams根本不起作用。如果我将“developer”作为关键字，将“New York”作为位置，则$ routeParam对象将如下所示:

{keywords: "?keywords=developer&location=New Yor", location: "k"}

有人可以告诉我我做错了什么吗？提前致谢。

P.S.
这可能是由于路由配置错误导致的吗？
当我通过 searchJobOffer函数导航时，它会将URL编码为: http://localhost:49380/#/joboffers%3Fkeywords=developer&location=london，如果我尝试使用此URL http://localhost:49380/#/joboffers?keywords=developer&location=london，则路由系统会将我引导至默认路由(＃/home)

$ routeProvider与查询字符串不匹配，仅与路由匹配。另外，您将完整的url设置为$ location.path()，而$ location.path()仅采用url的path部分。要设置包括查询字符串在内的整个URL，您需要使用$location.url()。

以下是一些选择:

1.改用漂亮的网址

$routeProvider.when("/joboffers/:location/:keywords", {
  controller: "jobOffersController",
  templateUrl: "/App/Views/JobOffer/All.html"
});

$scope.searchJobOffer = function () {
  var vm = $scope.jobOfferSearchViewModel;
  var path = "/joboffers/" + (vm.location || "") + "/" + ( vm.keywords || "");
  $location.path(path);
};

app.controller('jobOffersController', ['$scope', '$routeParams', 'jobOfferService', function ($scope, $routeParams, jobOfferService) {
  $scope.jobOffers = [];

  function init() {
    var keywords = $routeParams.keywords;
    var location = $routeParams.location;
  }

  init();
}]);

2.仅在工作上进行匹配才能提供路径，并从$ location.search()中提取参数

(请注意，使用 $location.url()而不是 $location.path())

$routeProvider.when("/joboffers", {
  controller: "jobOffersController",
  templateUrl: "/App/Views/JobOffer/All.html"
});

$scope.searchJobOffer = function () {
  var vm = $scope.jobOfferSearchViewModel;
  var url = "/joboffers?keywords=" +( vm.keywords || "") + "&location=" + (vm.location || "");
  $location.url(url);
};

app.controller('jobOffersController', ['$scope', '$location', 'jobOfferService', function ($scope, $location, jobOfferService) {
  $scope.jobOffers = [];

  function init() {
    var search = $location.search();
    var keywords = search.keywords;
    var location = search.location;
  }

  init();
}]);

3.如果您需要匹配路由和查询字符串，请尝试使用更强大的功能，例如 angular-ui-router

$stateProvider.state("JobOffers", {
  url: '/joboffers?keywords&location',
  controller: "jobOffersController",
  templateUrl: "/App/Views/JobOffer/All.html"
});

$scope.searchJobOffer = function () {
  var vm = $scope.jobOfferSearchViewModel;
  var url = "/joboffers?keywords=" +( vm.keywords || "") + "&location=" + (vm.location || "");
  $location.url(url);
};

app.controller('jobOffersController', ['$scope', '$stateParams', 'jobOfferService', function ($scope, $stateParams, jobOfferService) {
  $scope.jobOffers = [];

  function init() {
    var keywords = $stateParams.keywords;
    var location = $stateParams.location;
  }

  init();
}]);
