Am getting the below error when I try to download the a .pdf file from a url through my .exe file.
当我试图通过我的.exe文件从url下载.pdf文件时，我得到了下面的错误。
The server committed a protocol violation. Section=ResponseHeader Detail=CR must be followed by LF
服务器违反了协议。必须在后面加上LF。
but the same is getting downloaded when I try to debug the code from visual studio. I am totally lost, no clue of whats going on. Can somebody tell me what could be the problem
但是当我试图调试visual studio中的代码时，同样的情况也会被下载。我完全迷路了，一点线索也没有。谁能告诉我是什么问题吗
My App.config file
我的App.config文件
<?xml version="1.0"?>
<configuration>
<system.net>
<settings>
<httpWebRequest useUnsafeHeaderParsing="true" />
</settings>
</system.net>
</configuration>
useUnsafeHeaderParsing="true" is the obvious fix that everyone is stating on internet unfortunately it is not working
useunsafeheaderparser ="true"是显而易见的修正，每个人都在网上声明它不工作
Here is my webclient code
这是我的webclient代码
public class CookieAwareWebClient : WebClient {
private CookieContainer cc = new CookieContainer();
private string lastPage;
protected override WebRequest GetWebRequest(Uri address) {
if (address.Scheme == Uri.UriSchemeHttps) {
ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072 | SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls;
// allows for validation of SSL conversations
ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };
}
WebRequest R = base.GetWebRequest(address);
if (R is HttpWebRequest) {
HttpWebRequest wr = (HttpWebRequest)R;
wr.CookieContainer = cc;
if (lastPage != null) {
wr.Referer = lastPage;
}
}
lastPage = address.ToString();
return R;
}
}
Update : My .exe was able to download most of the url's except few. Consider I have 4 url's :A,B,C and D. My visual studio was able to download files from all 4 urls' but my .exe download's file from first 3 url's. For url, D it throws
更新:我的。exe能够下载url的大部分，除了少数。假设我有4个url:A、B、C和d。对于url，它会抛出。
The server committed a protocol violation. Section=ResponseHeader Detail=CR must be followed by LF
服务器违反了协议。必须在后面加上LF。
Update 2 : I was trying to trace D url using fiddler. When I ran the D url from browser to download the file, I got the below header and file was downloaded. Also note that D url is redirected to another url before downloading
更新2:我试图使用fiddler跟踪D url。当我从浏览器中运行D url下载文件时，我下载了下面的头文件。还要注意，D url在下载之前被重定向到另一个url
CONNECT www.loim.com:443 HTTP/1.1
Host: www.loim.com:443
Connection: keep-alive
User-Agent: Mozilla/5.0 (Windows NT 6.2; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36
When I tried to downlaod the file from D url using .exe I got the below header
当我试图用。exe从D url下拉文件时，我得到了下面的头文件
CONNECT www.loim.com:443 HTTP/1.1
Host: www.loim.com
Connection: Keep-Alive
For some reason the User-Agent is that the problem ?
由于某种原因，用户代理是问题所在吗?

The application configuration file needs to be in the same folder as the .exe. When you deploy CLImport.exe you should also deploy CLImport.exe.config to that folder.
应用程序配置文件需要与.exe位于同一个文件夹中。当你部署CLImport。你还应该部署CLImport.exe。配置文件夹。
