angularJS 利用 service 封装 POST 请求

angular.module('app',[]).service('postService',function($http){
    return {
        postRequset:function(url,obj,succCallBack,errorCallBack){
           return $http({
                method:'post',
                url:url,
                data:obj || {},
                headers:{'Content-Type':'application/x-www-form-urlencoded'},
                transformRequest:function(obj){
                    var str = [];
                    for(var p in obj ){
                        str.push(encodeURIComponent(p) + '=' + encodeURIComponent(obj[p]);
                    }
                    return str.join('&');
                }
            }) .success(function(data){
                    succCallBack && succCallBack(data);
            }).error(function(data){
                   errorCallBack && errorCallBack(data);
            })
        }
    }
})            

　　

以下为重点:
headers:{'Content-Type':'application/x-www-form-urlencoded'},
transformRequest:function(obj){
      var str = [];
      for(var p in obj ){
          str.push(encodeURIComponent(p) + '=' + encodeURIComponent(obj[p]);
      }
      return str.join('&');
}

调用方法如下:

postService.postRequest('url的地址','data数据',function(data){
    console.log(data);
})
