angularjs有本身封裝的ajax服務(wù)$http，因?yàn)橛脩T了jQuery的ajax，所以，自己封裝了一下angularjs的$http，代碼如下

app.factory('dataFactory', function ($http, $q){   var factory = {};   factory.getlist = function(endpoint, method, headers, params) {     var defer = $q.defer();     if (method == 'GET') {       $http({         url: endpoint,         method: "GET",         headers: headers,         params: params,       }).success(function (data) {         defer.resolve(data);       }).       error(function (data, status, headers, config) {         // defer.resolve(data);         defer.reject(data);       });     } else {       $http({         url: endpoint,         method: method,         headers: headers,         data: params,       }).success(function (data) {         defer.resolve(data);       }).       error(function (data, status, headers, config) {         // defer.resolve(data);         defer.reject(data);       });     }     return defer.promise;     };     return factory; }); 

在controller中引入dataFactory和$http即可使用更方便的調(diào)用ajax,一般情況下headers為

headers = {'Content-Type': 'application/json'};

params為一個(gè)json字符串

然后調(diào)用

dataFactory.getlist("/api/checkDuplicate", 'GET', headers, params).then(function(data) { //success函數(shù) },function(data){ //error函數(shù) }) 

但是其中又一次在項(xiàng)目中，后臺(tái)框架使用的是Struts框架，在一個(gè)Python中使用的很好的dataFactory，在這里的后臺(tái)取不到數(shù)，最后發(fā)現(xiàn)是應(yīng)為header設(shè)置不對(duì)，而且params的格式也不正確，可以把header修改為

 headers = {'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8'}；

上面dataFactory中else添加轉(zhuǎn)換params代碼：

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;         };       $http({         url: endpoint,         method: method,         headers: headers,         data: param(params),       }).success(function (data) {         defer.resolve(data);       }).       error(function (data, status, headers, config) {         // defer.resolve(data);         defer.reject(data);       });
