如下闡述一下AngularJS中使用$http實現跨域請求數據。javascript
AngularJS XMLHttpRequest:$http用於讀取遠程server的數據
html
$http.post(url, data, [config]).success(function(){ ... }); $http.get(url, [config]).success(function(){ ... }); $http.get(url, [config]).success(function(){ ... });
response.setHeader("Access-Control-Allow-Origin", "*"); //贊成所有域名訪問 response.setHeader("Access-Control-Allow-Origin", "http://www.123.com"); //贊成www.123.com訪問2. AngularJS端使用$http.get()
response.setHeader("Access-Control-Allow-Origin", "*"); response.setHeader("Access-Control-Allow-Methods","POST"); response.setHeader("Access-Control-Allow-Headers","x-requested-with,content-type");2. AngularJS端使用$http.post(),同一時候設置請求頭信息
$http.post('http://localhost/ajax/getAllIndustryCategoty.pt',{languageColumn:'name_eu'},{'Content-Type':'application/x-www-form-urlencoded'}).success(function(data){ $scope.industries = data; });
$http.jsonp("http://localhost/sitesettings/getBadgeInfo.pt?jsonp=JSON_CALLBACK&siteid=137bd406").success(function(data){ ... }); // The name of the callback should be the string JSON_CALLBACK.方法二【返回值。需要使用相應callback方法接收,但怎樣置於$scope??

前端
$http.jsonp("http://localhost/sitesettings/getBadgeInfo.pt?jsonp=badgeabc&siteid=137bd406"); function badgeabc(data){ ... }
public String execute() throws Exception { String result = FAIL; response.setHeader("", ""); SiteHandlerAction siteHandlerAction = (SiteHandlerAction)BeansFactory.getBean(SiteHandlerAction.class); BadgeHandlerAction badgeHandlerAction = (BadgeHandlerAction)BeansFactory.getBean(BadgeHandlerAction.class); if("".equals(siteid) || siteid == null || StringUtils.isBlank("jsonp")){ result = FAIL; }else{ Site site = siteHandlerAction.find(siteid); UserBadgeStatus userBadgeStatus = badgeHandlerAction.getUserBadgeStatus(site.getId()); if(userBadgeStatus != null){ result = "{\"t\":"+userBadgeStatus.getStyle()+",\"l\":"+userBadgeStatus.getSuspend_location()+",\"s\":"+site.getId()+"}"; JSONObject jsonObj = JSONObject.fromObject(result); String json = jsonObj.toString(); result = jsonp + "(" + json + ")"; } } PrintWriter write = response.getWriter(); write.print(result); write.flush(); write.close(); return NONE; }
function getAdustryController($scope,$http){ $http.get('http://localhost/ajax/getAllIndustryCategoty.pt?languageColumn=name_eu').success(function(data){ $scope.industries = data; }); }
function getAdustryController($scope,$http){ $http.post('http://localhost/ajax/getAllIndustryCategoty.pt',{languageColumn:'name_eu'},{'Content-Type':'application/x-www-form-urlencoded'}).success(function(data){ $scope.industries = data; }); }
// java端支持跨域請求 public String execute(){ response.setHeader("Access-Control-Allow-Origin", "*"); //贊成哪些url可以跨域請求到本域 response.setHeader("Access-Control-Allow-Methods","POST"); //贊成的請求方法,一般是GET,POST,PUT,DELETE,OPTIONS response.setHeader("Access-Control-Allow-Headers","x-requested-with,content-type"); //贊成哪些請求頭可以跨域 SiteHandlerAction SiteHandler = (SiteHandlerAction) BeansFactory.getBean(SiteHandlerAction.class); List<IndustryCategory> list = SiteHandler.getAllIndustryCategory(); //所有的分類集合 JSONArray jsonArray = JSONArray.fromObject(list); //將list轉爲json String json = jsonArray.toString(); //轉爲json字符串 try { PrintWriter write = response.getWriter(); write.print(json); write.close(); } catch (IOException e) { e.printStackTrace(); } return NONE; }
<table ng-controller="getAdustryController"> <tr ng-repeat='industry in industries'> <td>{{ industry.id }}</td> <td>{{ industry.name_ch }}</td> <td>{{ industry.name_eu }}</td> <td>{{ industry.name_jp }}</td> </tr> </table>
