AngularJs中$http发送post或者get请求,SpringMVC后台接收不到参数值的解决办法

1.问题原因

默认情况下，jQuery传输数据使用Content-Type: x-www-form-urlencodedand和类似于"name=zhangsan&age=18"的序列，然而AngularJS，传输数据使用Content-Type: application/json和{ "name": "zhangsan","age": "18" }这样的json序列。

2.解决办法

A.服务端进行修改，在Controller接收参数的方法中，对象前加 @RequestBody (注：要用对象的方式来接参数)
B.客户端修改

$http.post(url,{},{params:{"name": "zhangsan","age": "18"}}).success(function(data){

    });
    
$http.get(url,"age": "18"}}).success(function(data){

    });

C.修改Angular的$httpProvider的默认处理： http://victorblog.com/2012/12/20/make-angularjs-http-service-behave-like-jquery-ajax/ （适用于post,推荐）

var starter = angular.module('module',['ionic','ui.router']).run(function(){});
    
starter.config(['$httpProvider',function($httpProvider) {
    
    $httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded;charset=utf-8';

    var param = function(obj) {
        var query = '',name,value,fullSubName,subName,subValue,innerObj,i;

        for(name in obj) {
            value = obj[name];

            if(value instanceof Array) {
                for(i=0; i<value.length; ++i) {
                    subValue = value[i];
                    fullSubName = name + '[' + i + ']';
                    innerObj = {};
                    innerObj[fullSubName] = subValue;
                    query += param(innerObj) + '&';
                }
            }else if(value instanceof Object) {
                for(subName in value) {
                    subValue = value[subName];
                    fullSubName = name + '[' + subName + ']';
                    innerObj = {};
                    innerObj[fullSubName] = subValue;
                    query += param(innerObj) + '&';
                }
            }else if(value !== undefined && value !== null)
                query += encodeURIComponent(name) + '=' + encodeURIComponent(value) + '&';
            }

        return query.length ? query.substr(0,query.length - 1) : query;
    };

    $httpProvider.defaults.transformRequest = [function(data) {
        return angular.isObject(data) && String(data) !== '[object File]' ? param(data) : data;
    }];
}]);
