浅谈angular.js跨域post解决方案

$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", "*"); //允许所有域名访问
response.setHeader("Access-Control-Allow-Origin", "http://www.123.com"); //允许www.123.com访问

response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Methods","POST");
response.setHeader("Access-Control-Allow-Headers","x-requested-with,content-type");

$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").success(function(data){ ... });
// The name of the callback should be the string JSON_CALLBACK.

$http.jsonp("http://localhost/sitesettings/getBadgeInfo.pt");
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"htmlcode">

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端支持跨域请求
public String execute(){
 response.setHeader("Access-Control-Allow-Origin", "*"); //允许哪些url可以跨域请求到本域
 response.setHeader("Access-Control-Allow-Methods","POST"); //允许的请求方法，一般是GET,POST,PUT,DELETE,OPTIONS
 response.setHeader("Access-Control-Allow-Headers","x-requested-with,content-type"); //允许哪些请求头可以跨域
 
 SiteHandlerAction SiteHandler = (SiteHandlerAction) BeansFactory.getBean(SiteHandlerAction.class);
 List list = SiteHandler.getAllIndustryCategory(); //所有的分类集合
 JSONArray jsonArray = JSONArray.fromObject(list); //将list转为json
 String json = jsonArray.toString(); //转为json字符串
 try {
 PrintWriter write = response.getWriter();
 write.print(json);
 write.close();
 } catch (IOException e) {
 e.printStackTrace();
 }
 return NONE;
}
