angularjs简单实现$http.post，CORS跨域及$http.post传参方式模拟jQuery.post

1.开启angularjs的CORS支持

.config(function($httpProvider) { // CORS post跨域配置
    $httpProvider.defaults.useXDomain = true;  
    $httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded;charset=utf-8';
    var param = function(obj) {  // 修改angularjs $http.post的默认传参方式
        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;
    }];

    delete $httpProvider.defaults.headers.common['X-Requested-With']; 
})

2.开启服务器端CORS支持

header('Access-Control-Allow-Origin: *');

仅仅需要这两段代码即可！
