c# - "The requested resource does not support HTTP method ' PUT' ASP.Net Web API

Question

我的 jQuery Put 请求不起作用，当我在 Debug模式下运行我的代码时，put 函数没有被调用，从 FireBug 中我可以看到这个错误:

The requested resource does not support HTTP method 'PUT'

这是我的 jQuery 代码和 API Controller :

<script>
$(document).ready(function() {
    $('#success').hide();

    function onSelect(e) {
        $("#Type").prop("checked", false);

        var name = $("#TreeView").data("kendoTreeView").dataItem(e.node).Name;
        var accountId =$("#TreeView").data("kendoTreeView").dataItem(e.node).AccountId;

        $("#AccountID").val(accountId).prop("disabled",true);

        $("#Name").val(name).prop("disabled",true);

        var type = $("#TreeView").data("kendoTreeView").dataItem(e.node).Nature;

Answer 1

删除

[AcceptVerbs("POST", "Get")]

并改变

[System.Web.Http.HttpPost]

到

[System.Web.Http.HttpPut]

HttpPost 是 AcceptVerbs("POST") 的简写。没有你在哪里告诉 Controller 接受 PUT。我不认为你可以让一个 Controller 方法接受多个动词，即使你可以我觉得更清晰的实现是有两个同名的方法，一个用 HttpGet 修饰，一个用 HttpPut 修饰。
