我有问题从我的WCF服务（4.0）服务的jQuery DataTables.Net ajax POST调用获取有效的json。我尝试过很多组合，无法获得aoData的值。json WCF服务从jQuery DataTables ajax调用获取错误的请求400？
[Apols这么多的代码...想我应该贴最好的一切我能想到的！]
这是呼叫，从IE F12调试：
Key Value
Request POST /CustomerService.svc/json/GetCustomerDataTable HTTP/1.1

"{ jsonAOData : [{"name":"sEcho","value":1},{"name":"iColumns","value":7},{"name":"sColumns","value":""},{"name":"iDisplayStart","value":0},{"name":"iDisplayLength","value":10},{"name":"mDataProp_0","value":"CustomerNumber"},{"name":"mDataProp_1","value":"FirstName"},{"name":"mDataProp_2","value":"FamilyName"},{"name":"mDataProp_3","value":"MobileNumber"},{"name":"mDataProp_4","value":"CustomerIdNumber"},{"name":"mDataProp_5","value":"CustomerIdType"},{"name":"mDataProp_6","value":"DateOfBirth"},{"name":"sSearch","value":""},{"name":"bRegex","value":false},{"name":"sSearch_0","value":""},{"name":"bRegex_0","value":false},{"name":"bSearchable_0","value":true},{"name":"sSearch_1","value":""},{"name":"bRegex_1","value":false},{"name":"bSearchable_1","value":true},{"name":"sSearch_2","value":""},{"name":"bRegex_2","value":false},{"name":"bSearchable_2","value":true},{"name":"sSearch_3","value":""},{"name":"bRegex_3","value":false},{"name":"bSearchable_3","value":true},{"name":"sSearch_4","value":""},{"name":"bRegex_4","value":false},{"name":"bSearchable_4","value":true},{"name":"sSearch_5","value":""},{"name":"bRegex_5","value":false},{"name":"bSearchable_5","value":false},{"name":"sSearch_6","value":""},{"name":"bRegex_6","value":false},{"name":"bSearchable_6","value":false},{"name":"iSortCol_0","value":0},{"name":"sSortDir_0","value":"asc"},{"name":"iSortingCols","value":1},{"name":"bSortable_0","value":true},{"name":"bSortable_1","value":true},{"name":"bSortable_2","value":true},{"name":"bSortable_3","value":true},{"name":"bSortable_4","value":true},{"name":"bSortable_5","value":false},{"name":"bSortable_6","value":false}]}"
这是给错误：
There was an error deserializing the object of type System.String. The token 'null' was expected but found 'name'.
我试过各种方式建立data: '"{ jsonAOData : ' + jsonAOData + '}"',，但还没有找到任何有效的组合。
我看过很多关于SO的东西，但还没有找到解决方案。
注：
如果我派：
data: '{ "jsonAOData" : "' + 'BOBBLE' + '"}',
然后我回去错误：
There was an error deserializing the object of type System.String. End element 'root' from namespace '' expected. Found element 'jsonAOData' from namespace ''.
TBH：我不知道这是什么意思！这是一个字符串，不是XML，所以它为什么要寻找“根” - 除此之外，我想要jsonAOData，不是吗？
注意
如果我打电话给我的MVC3控制器相同的呼叫（只是一个不同的URI），那么它将按预期工作，我让我的jsonAOData字符串正确穿过？
