Question

我收到的格式是：

$(document).ready(function(){
    var off = $(".navbar-static-top").height() + 80; 
    var off2 = $("footer").height() + 30;
    $(".awrap > div:nth-child(1)").attr('data-offset-top', off.toString(); );
    $(".awrap > div:nth-child(1)").attr('data-offset-bottom', off2.toString(); );           
    $(function() {
        var $affixElement = $('div[data-spy="affix"]');
            $affixElement.width($affixElement.parent().width());
    });
});

主要问题似乎是无论我尝试什么，我都会收到错误＆＃34; [{"item1": "value1","item2": "value2"},{"item1": "value2","item2": "value4"}]＆＃34; 搜索互联网只需要将数组包装在顶级变量中（即数组不能位于根级别）。不幸的是，我无法改变接收数据的内容和方式。

以下是我尝试注释的所有代码：

我的测试ajax用于模拟第三方将发送给我的内容：

＆＃34; test.html＆＃34;：

的负责人

Type System.Collections.Generic.IDictionary'2 Is Not supported for deserialization of an array.

＆＃34; test.html＆＃34;

        //theData = '{"item1": "value1","item2": "value2"}'; //I can make a single array element work, but that is not what I will receive

        $.ajax({

                alert(msg);

        });
    }

Test.aspx.vb in the complete：

<input type="submit" value="test Post" onClick="testPost();" /><br>

＆＃34; Test_Request＆＃34;类：

Imports System.Collections.Generic
Imports System.Web.Script.Serialization

Partial Class test2
    Inherits System.Web.UI.Page

    '    Public Shared Function test_array(ByVal item1 As String, ByVal item2 As String) As String ' works if I am passing a single array element
    '    Public Shared Function test_array(ByVal theobj As Object) As String ' "Type System.Collections.Generic.IDictionary`2 Is Not supported for deserialization of an array."

    Public Shared Function test_array(ByVal d As List(Of Test_Request)) As String

        Return "test"

    End Function

End Class

如果我没有包含任何所需数据，请告诉我。我已经在圈子里进行了几天，在决定发布之前，我试图在这个测试模拟中重新创建我失败的所有尝试。希望有一些我忽略的东西。

在我看来，您正在尝试反序列化一组字典对象。我会做如下的事情。

在服务器端：

<HttpPost>
<Route("test")>
Public Function test(data As YourArray) As String

    Return "done"
End Function
-----------

Public Class YourArray
    Inherits List(Of YourDictionaryObject )
End Class

Public Class YourDictionaryObject 
    Inherits Dictionary(Of String, String)
End Class

我刚刚测试过，我可以确认以下内容确实有效：

function doTest() {
    var theData = [];
    theData.push({
        item1: "value1",
        item2: "value2"
    });
    theData.push({
        item1: "value3",
        item2: "value4"
    });

    $.ajax({
        type: "POST",
        contentType: "application/json",
        url: "somewhere/test",
        data: JSON.stringify(theData),
        dataType: "json",
        success: function(msg) {
            alert(msg);
        }
    });


}

我查了一下，Request Payload看起来像这样：

[{"item1":"value1","item2":"value2"},{"item1":"value3","item2":"value4"}]

这在服务器端反序列化为YourArray。顺便说一下，我使用的是Asp.net Web Api（不是WCF，序列化/反序列化字典可能很棘手）。

你的poco错了。 Item1和Item2需要是字符串数组

Public Class RootObject
       Public Property item1() As String
       Public Property item2() As String
End Class

无法接收由第三方发布给我的JSON数组
