Content-Length标头已删除 [英] Content-Length header is removed

问题描述

似乎我们在Azure中已经托管了一段时间的asp.net mvc(完整框架)已更改为Chuncked模式.

It seems the asp.net mvc (full framework) we've been hosting for a while in Azure is changed to Chuncked mode.

我们的WPF客户端应用程序依赖于要从服务器发送的content-length标头，但是该标头在最后几天会自动从响应中删除.

Our WPF client app depends on the content-length header to be send from the server, but the last days this header is automaticly removed from the response.

公共异步任务< ActionResult>索引(字符串appName，字符串ID，字符串curVersion){
AppFileInfo info = this.GetAppFile(appName，id，curVersion);
如果(info == null)返回新的HttpNotFoundResult(未找到应用程序");

this.Response.Buffer = false;
this.Response.BufferOutput = false;
this.Response.Headers ["Content-Encoding"] ="identity";
this.Response.Headers ["Transfer-Encoding"] ="identity";

版本v = Version.Parse(info.Version);
StorageHelper store = new StorageHelper();
FileStreamResult result = await store.GetFileStreamResult("versions"，new string [] {appName，v.Major.ToString()}，info.Name)为FileStreamResult;

this.Response.Headers.Add("Content-Length"，result.FileStream.Length.ToString());

返回结果；
}

public async Task<ActionResult> Index(string appName, string id, string curVersion) {
AppFileInfo info = this.GetAppFile(appName, id, curVersion);
if (info == null) return new HttpNotFoundResult("Application Not Found");

this.Response.Buffer = false;
this.Response.BufferOutput = false;
this.Response.Headers["Content-Encoding"] = "identity";
this.Response.Headers["Transfer-Encoding"] = "identity";

Version v = Version.Parse(info.Version);
StorageHelper store = new StorageHelper();
FileStreamResult result = await store.GetFileStreamResult("versions", new string[] { appName, v.Major.ToString() }, info.Name) as FileStreamResult;

this.Response.Headers.Add("Content-Length", result.FileStream.Length.ToString());

return result;
}

如果我在开发箱上本地运行此代码，则可以按预期工作，当发布为天蓝色时，不会发送content-length标头.

If I run this code locally on my dev-box it works as expected, when published to azure, the content-length header is not send.
