当我访问我的页面时，一次get请求被激发4次，而应该被激发2次。看看下面的图片：
这是我的代码：
index.html：
<!DOCTYPE html>
<html ng-app="cryptlib">
<head>
<link href="css/style.css" rel="stylesheet" type="text/css">
<meta content="text/html;charset=UTF-8" http-equiv="content-type" />

<body ng-controller="firstPageController">
<div ng-view>
</div>
</body>

<div class="maincontent">

<div id="bottom">

<input type="text" ng-model="myModelObj">

</div>
controller.js
angular.module('cryptlib_controllers')
.controller('firstPageController', ['$scope','$http','$location','$sce','$rootScope','$upload', function($scope, $http, $location, $sce, $rootScope, $upload) {
$http({
url: 'lib/actions.php',
method: 'GET',
params: {get_books: 1}
}).success(function(data) {
$scope.books = data;
});
$http({
url: 'lib/actions.php',
method: 'GET',
params: {get_dirs: 1}
});
console.log($scope.books);
$scope.onFileSelect = function($files) {
//Vi har valt en eller flea filer
//$files är en array innehållande de valda filerna att ladda upp. Dess namn, storlek och typ
for(var i = 0; i < $files.length; i++)
{
var file = $files[i];
$scope.upload = $upload.upload({
url: 'lib/actions.php',
data: {myObj: $scope.myModelObj},
file: file
}).progress(function(evt) {
console.log('percent: ' + parseInt(100.0 * evt.loaded / evt.total));
}).success(function(data, status, headers, config) {
console.log(data);
});
}
};
$scope.items = ['Programmering', 'Elektronik'];
$scope.change = function() {
alert($scope.selectedItem);
}
}]).controller('bookController', ['$scope','$http','$location','$sce','$rootScope','$upload', function($scope, $http, $location, $sce, $rootScope, $upload) {
}]);
为什么访问该页面时会触发4次get请求？它应该只被发射2次？谁能解释？
最佳答案
因为您两次定义了firstPageController。首先在body标签中，然后在路线中。
关于javascript - 加载页面时出现多个获取请求，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/29167266/
