| 一直都用Jsonp的方式來解決angularjs跨域問題,查詢讀取信息還可以。如果是遇到比如登陸,需要post用戶信息的,這個時候必須要用到post方式。 研究了幾天,今天終于測試成功: 感謝谷歌搜索給予很大支持,馬上奉上方法吧。 我的server端用的是php作為接口,在post數(shù)據(jù)的接口處加上下面代碼: header('Access-Control-Allow-Origin: *'); header('Access-Control-Allow-Headers: X-Requested-With'); 然后在angularjs處$http要按照下面方式寫: $http({ url:'http://www./index.php?app=api&ac=user&ts=login', method:"POST", headers: { 'Content-Type': 'application/x-www-form-urlencoded' }, data: { 'email': 'root@qq.com','password': '123456' } }); 按照以上方式處理測試成功。 AngularJS實現(xiàn)跨域請求跨域,前端開發(fā)中經(jīng)常遇到的問題,AngularJS實現(xiàn)跨域方式類似于Ajax,使用CORS機制。 下面闡述一下AngularJS中使用$http實現(xiàn)跨域請求數(shù)據(jù)。 AngularJS XMLHttpRequest:$http用于讀取遠程服務(wù)器的數(shù)據(jù) $http.post(url, data, [config]).success(function(){ ... });
$http.get(url, [config]).success(function(){ ... });
$http.get(url, [config]).success(function(){ ... });一、$http.jsonp【實現(xiàn)跨域】1. 指定callback和回調(diào)函數(shù)名,函數(shù)名為JSON_CALLBACK時,會調(diào)用success回調(diào)函數(shù),JSON_CALLBACK必須全為大寫。2. 指定其它回調(diào)函數(shù),但必須是定義在window下的全局函數(shù)。url中必須加上callback。 二、$http.get【實現(xiàn)跨域】1. 在服務(wù)器端設(shè)置允許在其他域名下訪問response.setHeader("Access-Control-Allow-Origin", "*"); //允許所有域名訪問
response.setHeader("Access-Control-Allow-Origin", "http://www."); //允許www.訪問2. AngularJS端使用$http.get()三、$http.post【實現(xiàn)跨域】1. 在服務(wù)器端設(shè)置允許在其他域名下訪問,及響應(yīng)類型、響應(yīng)頭設(shè)置response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Methods","POST");
response.setHeader("Access-Control-Allow-Headers","x-requested-with,content-type");2. AngularJS端使用$http.post(),同時設(shè)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){
		$scope.industries = data;
	});四、實現(xiàn)方式跨域方式一【JSONP】:方法一:$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,需要使用對應(yīng)callback方法接收,但如何置于$scope???】:$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;
}跨域方式二【$http.get()】:function getAdustryController($scope,$http){
	$http.get('http://localhost/ajax/getAllIndustryCategoty.pt?languageColumn=name_eu').success(function(data){
		$scope.industries = data;
	});
}跨域方式三【$http.post()】: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", "*"); //允許哪些url可以跨域請求到本域
	response.setHeader("Access-Control-Allow-Methods","POST"); //允許的請求方法,一般是GET,POST,PUT,DELETE,OPTIONS
	response.setHeader("Access-Control-Allow-Headers","x-requested-with,content-type"); //允許哪些請求頭可以跨域
	
	SiteHandlerAction SiteHandler = (SiteHandlerAction) BeansFactory.getBean(SiteHandlerAction.class);
