然后想到这个Accept-Encoding,百度后知道,这个是用来设置从网站中接收的返回数据是否进行gzip压缩.这也就解释了为何返回的数据是大面积的粗体方块乱码,因为是压缩过的数据,也就不可能进行正常解码. http://blog.csdn.net/zhangxinrun/article/details/5711307这是一篇介绍gzip,deflate具体含义的博文 防止链接失效我直接摘...
在用httpclient做网页提取的过程中,通过抓包工具发现了 头部中会有 Accept-Encoding: gzip, deflate字段 如果头部有了该字段,则服务器会将内容reponse的内容进行压缩用gzip或者deflate算法,然后reponse给用户。目前我看到的仅仅有gzip算法被用到,然后返回给用户的数据也是压缩后的数据,这样往往可以减轻服务器的负担,同时也...

对于响应内容的压缩,一般Web服务器(比如IIS)都提供了内置支持,只需在请求头中包含 Accept-Encoding: gzip, deflate ,客户端浏览器与HttpClient都提供了内置的解压支持。HttpClient中启用这个压缩的代码如下: var httpClient = new HttpClient(new HttpClientHandler { AutomaticDecompression = System.Net.DecompressionMethods...

在用httpclient做网页提取的过程中,通过抓包工具发现了 头部中会有 Accept-Encoding: gzip, deflate字段,本文不介绍该字段具体是干什么的,只是告诉你在请求的时候,如果头部有了该字段,则服务器会将内容reponse的内容进行压缩用gzip或者deflate算法,然后reponse给用户。目前我看到的仅仅有gzip算法被用到,然后返回给用户的...
This is a breaking change compared to netcoreapp1.1. In netcoreapp1.1, HttpClient automatically sends header "Accept-Encoding": "gzip, deflate" in the request, and automatically decompress 'gzip/deflate' content from the response. Howeve...
