如何从角度js向web API发送二维数组 [英] How to send bi-dimensional array from angular js to web API

问题描述

我在桌面上运行了两个解决方案：一个是使用angularjs的Web解决方案，并调用另一个解决方案，这是一个基于MVC的Web API，都是用vb.net编写的。除了一件事之外，一切都很完美：当我尝试发送二维时，我得到以下错误：

I have two solutions running on my desktop: One is a web solution using angularjs and calling the other solution which is a web API based on MVC and both are written in vb.net. Everything is working perfectly except one thing: when I tried to send a bi-dimensional I got below error:

The request is invalid. The parameters dictionary contains an invalid entry for parameter 'myBiDimenArray' for method 'System.Web.Http.IHttpActionResult Calculate(System.String[,], Int32)' in 'CustomAPI.TestController'. The dictionary contains a value of type 'System.String[]', but the parameter requires a value of type 'System.String[,]'."

以下是我在角js中的代码：

Below is my code in angular js:

var myBiDimenArray = [
            [1, 6],
            [5, 2],
            [9, 10]
            ];

console.log(myBiDimenArray); // it logs the array correctly

return $http({
            method: "GET",
            url: urlBase + "Calculate",   
            params: {
                myBiDimenArray: myBiDimenArray,
                intSize: 1,
            },
            headers: {
                'Content-Type': 'application/json',
                'X-ApiKey': 'test' ,
                'Authorization': 'Basic 123456'
            }
        });

以下是我的代码Web APi：

Below is my code in Web APi:

<HttpGet>
    Public Function Calculate(<FromUri> ByVal myBiDimenArray(,) As String, <FromUri> ByVal intSize As Integer) As IHttpActionResult
  ....
 End Function

有什么建议？



我是新手，我已经在vb.net和JavaScript中搜索了如何创建Bi-Dimen数组，所以我在我的解决方案中实现了上述内容但是错误400被抛出甚至没有访问方法。





更新：



请请注意，这是我在webAPi配置文件中的路径：

Any suggestions?

I am new to this, I have searched for how to create Bi-Dimen Array in vb.net and in JavaScript so I implemented the above in my solutions but error 400 is thrown and method is even not accessed.


Update:

Please note that this is my route in webAPi config file:

config.Routes.MapHttpRoute( _
 name:="Test_Calculate", _
 routeTemplate:="api/{controller}/{action}/{myBiDimenArray}/{intSize}", _
 defaults:=New With {.controller = "Test", .action = "Calculate"} _
)

可能是配置问题吗？



我尝试过：



我已将网络APi方法更改为：

Could it be a configuration problem?

What I have tried:

I have changed the web APi method to this:

<HttpGet>
    Public Function Calculate(<FromUri> ByVal myBiDimenArray()() As String, <FromUri> ByVal intSize As Integer) As IHttpActionResult
  ....
 End Function

可以访问该方法，myBiDimenArray长度为3（这是正确的），但内部的每个数组都像String一样，例如：[1 ，6：：1个参数而不是数组中的2个参数;

The method could be accessed, myBiDimenArray length was 3 (which is correct), but each array inside was acting like a String, example: "[1,6]" : 1 parameter instead of being 2 params inside an array;

推荐答案

http（{
method：GET，
url：urlBase +Calculate，
params：{
myBiDimenArray：myBiDimenArray，
intSize：1，
}，
header：{
'内容-Type'：'application / json'，
'X-ApiKey'：'test'，
'授权'：'基本123456'
}
}）;

http({ method: "GET", url: urlBase + "Calculate", params: { myBiDimenArray: myBiDimenArray, intSize: 1, }, headers: { 'Content-Type': 'application/json', 'X-ApiKey': 'test' , 'Authorization': 'Basic 123456' } });

以下是我在Web APi中的代码：

Below is my code in Web APi:

<HttpGet>
    Public Function Calculate(<FromUri> ByVal myBiDimenArray(,) As String, <FromUri> ByVal intSize As Integer) As IHttpActionResult
  ....
 End Function
