仅 Chrome 中的无效 HTTP 状态代码 405

Question

我有一个将客户保存到数据库的 WCF 服务，在 Internet Explorer 中按预期工作，但在 [=31] 中不 =]（出于这个原因，我将省略 HTML/Json，因为它让我认为这是一个网络配置问题，但如果有人愿意，我可以 post）。

在 Chrome 中我得到错误：

无法加载资源：服务器响应状态为 405（方法不允许） Subscriber.htm:1 XMLHttpRequest 无法加载 http://example.com/MyService.svc/SaveCustomer。无效的 HTTP 状态代码 405

我的网络配置：

      </customHeaders>
    </httpProtocol>

所以我阅读了几篇文章并添加了相关部分，删除了 WebDav，但似乎没有什么不同。

好吧，我本来打算删除这个帖子的，但我想以后可能会有人遇到这个问题，以免他们头疼。

在我的网络配置中，我删除了（否则你会得到一个错误）

<httpProtocol>
  <customHeaders>
    <!-- Enable Cross Domain AJAX calls -->
    <add name="Access-Control-Allow-Origin" value="*" />
    <add name="Access-Control-Allow-Headers" value="Content-Type, Authorization, Accept, X-Requested-With" />
    <add name="Access-Control-Allow-Methods" value="OPTIONS, TRACE, GET, HEAD, POST, PUT" />
  </customHeaders>
</httpProtocol>

在我的 WCF Web 服务中，我添加了一个新的 Global.asax 并添加了

Sub Application_BeginRequest(sender As Object, e As EventArgs)
    HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*")
    If HttpContext.Current.Request.HttpMethod = "OPTIONS" Then
        HttpContext.Current.Response.AddHeader("Cache-Control", "no-cache")
        HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET, POST")
        HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "Content-Type, Accept")
        HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "1728000")
        HttpContext.Current.Response.End()
    End If
End Sub

希望对您有所帮助

Answer 2

计算机的答案适用于我的 ASP.NET MVC 5 站点，而其他解决方案则失败了。

这是他在 C# 中的 Global.asax 函数。

protected void Application_BeginRequest(object sender, EventArgs e)
{
    HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
    if (HttpContext.Current.Request.HttpMethod != "OPTIONS") return;
    HttpContext.Current.Response.AddHeader("Cache-Control", "no-cache");
    HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET, POST");
    HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "Content-Type, Accept");
    HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "1728000");
    HttpContext.Current.Response.End();
}
