$ resource.query返回拆分字符串(字符数组)而不是字符串 [英] $resource.query return split strings (array of char) instead of a string

问题描述

我正在使用像下面这样的有角度的$ resource.

I am using a angular $resource like the one below.

angular.module('app')
.factory('data', function ($resource) {

    var Con = $resource('/api/data', {}, {
        update : {method : 'PUT'}
    });

    return {     

        getData : function (user_id, callback) {

             return Con.query({user_id : user_id}, function (data) {
                 cb(data); // (breakpoint) HERE data is not good
             }, function (err) {
                 cb(err);
             }).$promise;
         }

   }; 
});

这是在数据上设置断点时得到的:

This is what I get when a put a breakpoint on data :

[
    ['w','e','l','c','o','m','e'],
    ['h','e','l','l','o']
] 

但是，服务器发送:

['welcome','hello']

有人知道为什么字符串会被分割吗?

anyone know why the strings get split?

谢谢

推荐答案

您已经遇到了angular的$ resource的一个有趣的错误，该错误无法处理原始的字符串数组；作为解决方法，您可以执行以下三种操作之一:

You've run into a fun bug with angular's $resource where it cannot handle a raw array of strings; as a workaround, you can do one of three things:

• 改为使用$ http服务
• 通过服务器发送对象包装的响应，例如:{ "stuff" : [ "your", "strings" ] }
• 将响应数据强制转换为上述客户端格式； $ resource例如:methodName: {method:'GET', url: "/some/location/returning/array", transformResponse: function (data) {return {list: angular.fromJson(data)} }}，然后以data.list
的身份访问

• use the $http service instead
• send an object-wrapped response via the server eg: { "stuff" : [ "your", "strings" ] }
• force the response data into the above format client-side; $resource eg: methodName: {method:'GET', url: "/some/location/returning/array", transformResponse: function (data) {return {list: angular.fromJson(data)} }} and then access it as data.list
