还没有引用.服务器提交协议冲突 Section=ResponseStatusLine 的解决办法
　　最近写程序抓取数据，发现对有的网站用HttpWebrequest抓取网页的时候会报错，捕获异常提示："服务器提交了协议冲突 Section=ResponseStatusLine ”,改用WebClient也是同样问题，后来知道，WebClient是对HttpWebrequest进一步进行了封装。最后终于找到问题根源：The
violation.
Section=ResponseHeader
LF 微软没有容忍不符合RFC
822中的httpHeader必须以CRLF结束的规定的服务器响应。通过修改配置文件解决：在app.config(WinForm)或web.config(Web)文件里修改。WinForm下的app.config默认不存在，手动在Debug文件夹所在的同级目录下新建一个XML配置文件，内容为：& xml version="1.0" encoding="utf-8"
&&configuration&&system.net&
&settings&
&httpWebRequest
useUnsafeHeaderParsing= "true "
&/settings&
&/system.net&&/configuration&编译以后会在Debug下面自动创建一个 程序nfig 的配置文件查看: 4815|回复: 2

我的代码：string url = &http://192.168.0.184/cgi-bin/wagent?webipcinfo+list&;
& && && && &HttpHelper httpHelper = new HttpHelper();
& && && && &HttpItem item=new HttpItem ();
& && && && &item.URL=
& && && && &item.ResultType = ResultType.S
& && && && &HttpResult r = httpHelper.GetHtml(item);

它提示：服务器提交了协议冲突. Section=ResponseHeader Detail=标头名称无效
PerkySu() 11:08:13
ContentType = &text/html&这个参数没有设置
PerkySu() 11:09:05
要返回什么样的数据要写成什么样的头信息的。
PerkySu() 11:09:09
/thread-.html
小小程序员() 11:10:13
设置了也不行
小小程序员() 11:10:57
还是提示：服务器提交了协议冲突. Section=ResponseHeader Detail=标头名称无效
PerkySu() 11:12:52
myRequest.ContentType = &application/x-www-form-urlencoded&;
PerkySu() 11:13:04
item.ContentType = &application/x-www-form-urlencoded&

[code=csharp]服务器提交了协议冲突.Section=ResponseHeader Detail=CR 后面必须是LF.
微软没有容忍不符合RFC 822中的httpHeader必须以CRLF结束的规定的服务器响应所导致.
解决方案分别是在web.config配置
& & &system.net&
& & &settings&
& & &httpWebRequest useUnsafeHeaderParsing=”true” /&
& & &/settings&
& & &/system.net&
PerkySu() 11:14:13
我建议你去看看Httphelper原理再写，要不然你的问题让我很头疼。
PerkySu() 11:14:20
问的很另类

在Config中配置下，可以了

[code=csharp]服务器提交了协议冲突. Section=ResponseHeader Detail=CR 后面必须是 LF&&
The server committed a protocol violation. Section=ResponseHeader Detail=CR must be followed by LF&&
主体意思是微软没有容忍不符合RFC 822中的httpHeader必须以CRLF结束的规定的服务器响应。&&
解决方案是在app.config或web.config文件里加入
&configuration&
& & &system.net&
& && &&&&settings&
& && && && &&httpWebRequest useUnsafeHeaderParsing=&true& /&
& && &&&&/settings&
& & &/system.net&
&/configuration&&?xml version=&1.0& encoding=&utf-8& ?&
&configuration&
& & &system.net&
& && &&&&settings&
& && && && &&httpWebRequest useUnsafeHeaderParsing=&true& /&
& && &&&&/settings&
& & &/system.net&
&/configuration&
允许系统容忍（tolerant）只以CR或LF结尾的hearder信息&&[/code]

We started with Q&A. Technical documentation is next, and we need your help.
Whether you're a beginner or an experienced developer, you can contribute.
I am trying to use a WebClient / HttpWebRequest to download some data from a server. I use the following code to do so:
WebClient client = new WebClient();
client.Credentials = new NetworkCredential("admin", "password");
Stream datastream = client.OpenRead("/cgi-bin/CF_logs.html");
StreamReader reader = new StreamReader(datastream);
The server is my page is in my router's configuration. It works fine from a browser, but when downloaded using my code it throws a WebException with the message
The server committed a protocol violation. Section=ResponseHeader Detail=CR must be followed by LF, In WinForms?.
I have found a solution one would use if they were using ASP.net, adding the following to web.config:
&configuration&
&system.net&
&settings&
&httpWebRequest useUnsafeHeaderParsing="true" /&
&/settings&
&/system.net&
&/configuration&
However, I am making a WinForms app so this won't work for me. What alternatives are there to fix this problem?

First, adding an app.config file is just as easy as adding any other file,
Then you just have to add that code snippet above to that new app.config.
Another way of setting that property via code, avoiding the need for an app.config is shown
