不包括“期望：100-继续”来自HttpWebRequest POST的标头 [英] Excluding the "Expect: 100-Continue" header from HttpWebRequest POSTs

问题描述

我正在使用HttpWebRequest发布到不知道如何处理Expect 100标头的服务器。 显然这不是一个罕见的问题。 菲尔·哈克几年前在博客上发表了一篇博文，其中包括一个简单的解决方案：

http://haacked.com/archive/2004/05/15/http-web-request-expect-100-continue.aspx

建议的解决方案是设置System.Net.ServicePoint.Expect100Continue。 但ServicePoint似乎是WinRT API收缩的不幸受害者，所以我无法访问它。 是否有替代解决方法？

嗨Robert，

我将研究如何防止在没有ServicePoint或ServicePointManager的情况下发送Expect：100-continue标头并返回给您。

I'm using HttpWebRequest to post to a server which doesn't know how to deal with the Expect 100 header.  Apparently this isn't an uncommon problem.  Phil Haack blogged about it several years ago, including a simple solution: http://haacked.com/archive/2004/05/15/http-web-request-expect-100-continue.aspx

The solution proposed there is to set System.Net.ServicePoint.Expect100Continue.  But ServicePoint seems to have been an unfortunate victim of the WinRT API shrinkage so I can't access it.  Is there an alternative workaround?

Hi Robert,

I'll look into how to prevent sending the Expect: 100-continue header without ServicePoint or ServicePointManager and get back to you.
