angularjs学习笔记(一)

错误原因：http请求头错误

解决方法如下：

app.config(function($httpProvider) {
    $httpProvider.defaults.headers.put['Content-Type'] = 'application/x-www-form-urlencoded';
    $httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';
 
    // Override $http service's default transformRequest
    $httpProvider.defaults.transformRequest = [function(data) {
        /**
         * The workhorse; converts an object to x-www-form-urlencoded serialization.
         * @param {Object} obj
         * @return {String}
         */
        var param = function(obj) {
            var query = '';
            var 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;
        };
 
        return angular.isObject(data) && String(data) !== '[object File]'
                ? param(data)
                : data;
    }];
});
