因此,当我将文件发送到 MVC 控制器时,此 Kendo UI Upload 运行良好,但我必须更改它并将文件直接发送到 API 控制器,但它失败了。
这是剑道上传的初始化代码:
$("#files").kendoUpload({
async: {
saveUrl: "@WebApiHelper.GetUrl("Notification/UploadFile")",
removeUrl: "remove",
autoUpload: true
},
success: function(),
error: function()
}
在 Chrome 控制台上,它显示Load Canceled
在网络选项卡中请求的状态文本中:
请求的结果如下图所示:

请注意,状态码是 200,因为我在方法中返回了它。所以它到达API方法......
[HttpPost][HttpOptions]
public HttpResponseMessage UploadFile(HttpPostedFileBase files)
...但files
参数是 aways null
。
这是 API webconfig 文件中与 CORS 相关的属性:
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="*" />
<add name="allow-access-from domain" value="*" />
<add name="Access-Control-Allow-Headers" value="origin, accept, content-type" />
<add name="Access-Control-Allow-Methods" value="GET, POST, PUT, DELETE, OPTIONS" />
<add name="Access-Control-Allow-Credentials" value="true" />
</customHeaders>
</httpProtocol>
有什么想法吗 ?任何帮助将不胜感激!
