c# HttpClient身份验证不工作(AXIS Cam cgi API)

本文关键字：Cam cgi API AXIS HttpClient 身份验证 工作 | 更新日期: 2023-09-27 18:11:26

我尝试了很多不同的方法来验证，但没有一个工作，要么程序崩溃，要么我没有得到响应:

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);
                }
            }
        }
    }

这里是一些请求头和响应，当我尝试链接(http://192.168.68.127/axis-cgi/param.cgi)在我的web浏览器有和没有密码的用户名:

您可以这样做:

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，相机方面存在CRLF问题，因此app.config或web中的参数useUnsafeHeaderParsing。配置可能有用:

<system.net>
    <settings>
      <httpWebRequest useUnsafeHeaderParsing="true" />
    </settings>
</system.net>
