mark一下：

初次使用angularjs在使用$http传递参数的时候，发现后台无论如何都获取不到参数，百度了一下，发现因为angularjs发送post请求时参数列表类型是 Payload,而后台想要接收参数的话,参数列表的类型需为 Formdata形成的kv模式的参数，所以需要对$http进行配置，发现两种配置模式，mark一下：

A：修改配置文件：

app.config(function ($httpProvider) {
            $httpProvider.defaults.headers.post[@H_301_14@'Content-Type'] = @H_301_14@'application/x-www-form-urlencoded;charset=utf-8';
            var param = function (obj) {
                var query = @H_301_14@'',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 + @H_301_14@'[' + i + @H_301_14@']';
                            innerObj = {};
                            innerObj[fullSubName] = subValue;
                            query += param(innerObj) + @H_301_14@'&';
                        }
                    }
                    else if (value instanceof Object) {
                        for (subName in value) {
                            subValue = value[subName];
                            fullSubName = name + @H_301_14@'[' + subName + @H_301_14@']';
                            innerObj = {};
                            innerObj[fullSubName] = subValue;
                            query += param(innerObj) + @H_301_14@'&';
                        }
                    }
                    else if (value !== undefined && value !== null)
                        query += encodeURIComponent(name) + @H_301_14@'=' + encodeURIComponent(value) + @H_301_14@'&';
                }
                return query.length ? query.substr(0,query.length - 1) : query;
            };
            // Override $http service's default transformRequest
            $httpProvider.defaults.transformRequest = [function (data) {
                return angular.isObject(data) && String(data) !== @H_301_14@'[object File]' ? param(data) : data;
            }];
        });

此时调用的时候data里就可以写KV模式的参数了：

$http({
     method  : @H_301_14@'POST',url     : @H_301_14@'/',data    : {@H_301_14@'username': $scope.username,@H_301_14@"password": $scope.password},})

B：传递参数修改：
这种感觉比较简答，mark下：

$http({
     method  : @H_301_14@'POST',url     : @H_301_14@'/',data    : $.param({@H_301_14@'username': $scope.username,@H_301_14@"password": $scope.password}),headers: {@H_301_14@'Content-Type': @H_301_14@'application/x-www-form-urlencoded; charset=UTF-8'}
})
