我正在尝试使用 AngularJS 将 http 发布到数据库中。我的代码没有显示任何错误，但我的数据库没有更新，我不知道为什么。这是我的代码:
//主题服务.js
(function() {
'use strict';
angular.module('topic').factory('topicService', topicServiceFunction);
topicServiceFunction.$inject = [ '$http', '$q' ];
function topicServiceFunction($http, $q) {
var topicService = {
getTopics : getTopics
}
return topicService;
function getTopics(obj) {
console.log('-->topicServiceFunction');
console.log(obj.name);
var deferred = $q.defer();
return $http.post('http://localhost:8080/restapp/api/topic',
JSON.stringify(obj)).then(function(response) {
if (typeof response.data === 'object') {
return response.data;
} else {
return deferred.reject(response.data);
}
}, function(response) {
return deferred.reject(response.data);
});
}
}
}())
//topic-controller.js
(function() {
'use strict';
angular.module('topic').controller('topicController',
topicControllerFunction);
topicControllerFunction.$inject = [ '$scope', 'topicService' ];
function topicControllerFunction($scope, topicService) {
$scope.getTopics = getTopics;
function getTopics(topicId,name,description,categId,userId) {
console.log('-->topictrlFunction');
$scope.topics = [];
var obj={
id:$scope.topicId,
name:$scope.name,
description:$scope.description,
id_category:$scope.categId,
user_id:$scope.userId
}
var promise = topicService.getTopics(obj);
promise.then(function(data) {
if (data != undefined && data != null) {
$scope.topics = data;
} else {
$scope.topics = undefined;
}
}, function(error) {
console.log('error=' + error);
$scope.topics = undefined;
})
topicService.getTopics(obj);
$scope.topics = topicService.getTopics(obj);
}
}
}())
//topic.html
<!DOCTYPE html>

最佳答案
在您的服务中，您使用 $q 但返回 $http promise ，这会适得其反，只需返回延迟 promise :
function getTopics(obj) {
console.log('-->topicServiceFunction');
console.log(obj.name);
var deferred = $q.defer();
var data = JSON.stringify(obj)
$http.post('http://localhost:8080/restapp/api/topic', data)
.then(function(response) {
if (typeof response.data === 'object') {
deferred.resolve(response.data);
} else {
deferred.reject(response.data);
}
})
.catch(function(response) {
return deferred.reject(response.data);
});
return deferred.promise;
}
如果它仍然不起作用，你应该尝试发送 urlencoded 数据而不是 json :
为此只需在您的请求中添加此 header :headers : {'Content-Type':'application/x-www-form-urlencoded; charset=UTF-8'}
并使用 $httpParamSerializerJQLike 服务对数据进行编码。 (将其注入(inject)您的服务中)
function getTopics(obj) {
console.log('-->topicServiceFunction');
console.log(obj.name);
var deferred = $q.defer();
var data = $httpParamSerializerJQLike(obj);
var config = {
headers : {'Content-Type':'application/x-www-form-urlencoded; charset=UTF-8'}
};
$http.post('http://localhost:8080/restapp/api/topic', data, config)
.then(function(response) {
if (typeof response.data === 'object') {
deferred.resolve(response.data);
} else {
deferred.reject(response.data);
}
})
.catch(function(response) {
return deferred.reject(response.data);
});
return deferred.promise;
}
