我尝试了很多不同的方法来进行身份验证，但没有一个起作用，要么程序崩溃，要么我没有得到任何响应：
async void GetRequest(string url)
{
//Test 1
/*var credentials = new NetworkCredential("root", "root");
var handler = new HttpClientHandler { Credentials = credentials };*/
//Test 2
/*var credCache = new CredentialCache();
credCache.Add(new Uri(url), "Digest", new NetworkCredential("root", "root"));
var handler = new HttpClientHandler { Credentials = credCache };*/
using (HttpClient client = new HttpClient(/*handler*/))
{
//Test 3
/*var encoding = new ASCIIEncoding();
var authHeader = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(encoding.GetBytes(string.Format("{0}:{1}", "root", "root"))));
client.DefaultRequestHeaders.Authorization = authHeader;*/
//Test 4 & 5
/*var headerVal = Convert.ToBase64String(Encoding.ASCII.GetBytes("root:root"));
var headerVal = Convert.ToBase64String(Encoding.UTF8.GetBytes("root:root"));
var header = new AuthenticationHeaderValue("Basic", headerVal);
client.DefaultRequestHeaders.Authorization = header;*/
using (HttpResponseMessage response = await client.GetAsync(url))
{
using (HttpContent content = response.Content)
{
string mycontent = await content.ReadAsStringAsync();
Debug.WriteLine(mycontent);
}
}
}
}
当我在网络浏览器中尝试使用或不使用密码用户名的链接（http://192.168.68.127/axis-cgi/param.cgi）时，以下是一些请求标头和响应：

您可以执行以下操作：
var uri = new UriBuilder("http://192.168.68.127")
{
Path = "axis-cgi/param.cgi",
Query = "action=list"
};
var request = (HttpWebRequest)WebRequest.Create(uri.Uri);
request.Credentials = new NetworkCredential("root", "root");
using (var response = await request.GetResponseAsync())
{
}
我必须提到，对于我拥有的一些相机和一些请求，相机端存在 CRLF 问题，因此 app.config 或 web.config 中的参数
useUnsafeHeaderParsing<system.net>
<settings>
<httpWebRequest useUnsafeHeaderParsing="true" />
</settings>
</system.net>
