C# 针对web api方法的奇怪405错误

因此，我真的很难做到这一点，我已经在互联网上搜索并尝试了我能找到的所有可能的建议

我有一个web api c#项目和一个JS web项目。在本地运行时，一切正常。当我发布到Azure时，我可以通过REST控制台点击我的api方法，一切正常。问题是，当我的web应用程序尝试执行相同的调用时，每个方法（除了初始令牌调用）都返回405

我已经使用CORS设置和web.config进行了很多次升级，我不确定是否还需要什么。。。它变得非常混乱，但我将尝试将相关的部分粘贴到这里

my web.config system.webServer设置

<modules>
  <remove name="FormsAuthentication" />
  <remove name="WebDAVModule"/>
</modules>

<httpProtocol>
  <customHeaders>
    <add name="Access-Control-Allow-Origin" value="*" />
  </customHeaders>
</httpProtocol>

<handlers>
    <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
    <remove name="OPTIONSVerbHandler" />
    <remove name="TRACEVerbHandler" />
    <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>

以及一个示例api控制器

    [Authorize]
    [Route("getall")]
    [HttpGet]
    public IHttpActionResult GetAll()
    {
        return Ok(PersonRepository.Get());
    }

和JS

$http.get（$rootScope.serviceBase+'api/person/getall'）

因此，总结一下这里的情况：

• 在本地运行时，调用工作正常
• 发布到Azure后，我可以直接调用rest端点
• 发布到Azure时，my JS返回405个非描述性错误
• 相反，如果我从web.config中删除CORS头并在我的Register方法中使用enableCors，我甚至不能点击/token，相反，我到处都会收到CORS飞行前错误（尽管我仍然可以从rest控制台成功调用），这非常令人困惑

更新

我会记录下我在这里尝试的东西：

将

添加到webConfig中的customHeaders，无更改

修正！多亏了各种stackoverflow帖子的汇编（我喜欢这个网站），我重建了我的web.config
