ApiController行动未能从查询字符串数组解析 [英] ApiController Action Failing to parse array from querystring

问题描述

使用Visual Studio 2012.2，MVC4 Web应用程序。

Using Visual Studio 2012.2, MVC4 web application.

我已经要求来我ApiController像这样：

I have requests coming to my ApiController like so:

http://localhost/api/keys?ids[]=1&ids[]=2&ids[]=3

和我是IM pression下，下面的方法应该能够自动地从IDS检索值[]数组：

And I was under the impression that the following method should be able to automagically retrieve the values from the ids[] array:

public KeysModel Get(int[] ids){...}

然而，当像上面这样一个请求时，在IDS的值参数为null。

However, when a request like the one above comes in, the value of the "ids" parameter is null.

我已经考察了HttpContext.Current.Request.QueryString对IDS的价值观，我能得到他们的方式，但是这使得单元测试更难了。

I have inspected that HttpContext.Current.Request.QueryString has the values for ids, and I could get to them that way, but that makes unit testing harder.

我使用列表ID也尝试过，[FromUri]，[FromUri（NAME =IDS []），对象ID和字符串ID（有趣的注意......当IDS是一个字符串变量，在值它是（集合）

I have also tried using List ids, [FromUri], [FromUri(Name="ids[]")], object ids, and string ids (interesting note... when ids is a string variable, the value within it is "(Collection)"

推荐答案

原来

public KeysModel Get([FromUri]int[] ids){...}

毕竟他回答。

不知道我在做之前...

Dunno what I was doing before...
