我正在挂火狐的发送和WSARecv。发送应删除gzip标头（=＆gt; Accept-Encoding：none），WSARecv挂钩应编辑数据。
目前，WSARecv函数不会更改任何数据，只会将其打印出来以用于调试日志。许多网站都可以使用，但有时图片无法加载或页面没有加载。
我可以在bing.com的WSARecv函数答案中找到以下服务器响应（错误400错误请求）：

我的问题是：我的HTTP标头出了什么问题？为什么有些页面会出现400错误。它是Accept-Encoding：none？
感谢阅读：）
答案 0 :(得分：2)
“none”不是“Accept-Encoding”标头的可接受值。并非所有服务器都会查看该标头，但那些服务器通常会在使用之前对其进行验证。要使服务器发送未压缩的数据，请完全省略标题，或将其设置为“identity”。
