【问题描述】:
我正在向 .NET 应用程序发送 AJAX 帖子,但尽管为 Content-Type 和 X-Requested-With 添加了正确的内容标头,但我仍然收到 IsAjaxRequest 返回 false。
配置设置正确的标头和序列化,然后底部的控制器处理 POST。
// Configure httpProvider
validationApp.config(['$httpProvider', function($httpProvider) {
// .NET AJAX FIX
$httpProvider.defaults.headers.common["X-Requested-With"] = 'XMLHttpRequest';
// Use x-www-form-urlencoded Content-Type
$httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded;charset=utf-8';
/**
* The workhorse; converts an object to x-www-form-urlencoded serialization.
* @param {Object} obj
* @return {String}
*/
var param = function(obj) {
var query = '', name, value, fullSubName, subName, subValue, innerObj, i;
for(name in obj) {
value = obj[name];
if(value instanceof Array) {
for(i=0; i<value.length; ++i) {
subValue = value[i];
fullSubName = name + '[' + i + ']';
innerObj = {};
innerObj[fullSubName] = subValue;
query += param(innerObj) + '&';
}
}
else if(value instanceof Object) {
for(subName in value) {
subValue = value[subName];
fullSubName = name + '[' + subName + ']';
innerObj = {};
innerObj[fullSubName] = subValue;
query += param(innerObj) + '&';
}
}
else if(value !== undefined && value !== null)
query += encodeURIComponent(name) + '=' + encodeURIComponent(value) + '&';
}
return query.length ? query.substr(0, query.length - 1) : query;
};
// Override $http service's default transformRequest
$httpProvider.defaults.transformRequest = [function(data) {
return angular.isObject(data) && String(data) !== '[object File]' ? param(data) : data;
}];
}]);
// POST
validationApp.controller('validationController', function($scope, $http) {
$scope.user = {};
$scope.update = function(user) {
if ($scope.uForm.$valid) {
$http.post('//ASPNET/EndPoint', $scope.user)
.success(function(response) {
})
.error(function(response) {
});
}
};
});
如您所见,请求标头已按应有的方式读取。并添加了以下内容。
内容类型:application/x-www-form-urlencoded;charset=UTF-8 X-Requested-With: XMLHttpRequest
据我所知,表单数据应该显示出来,但响应始终是 POST isAjaxRequest 为假。并且没有数据成功 POST。我在这里做错了什么?
