请求失败，HTTP 状态码 401：未经授权

基于这个问题中的问题，我发现自己处于同样的情况，我有一个报表生成器Web 服务，它在服务器上，我无法从客户端访问它。

为了允许我访问，我遵循了这些说明，但徒劳无功，我的连接代码是这样的：

连接字符串：

 private int _commandTimeout = 600;
        private Uri _reportServerUrl = new Uri("http://<Servidor>:80/ReportServer");
        private string _connectionString = ConfigurationManager.ConnectionStrings["DefaultConnection"].ConnectionString;
        private ReportViewer _reportViewer = new ReportViewer();

访问功能：

 public string CargaInforme(int reportId)
    {
        string nomInforme = "";

        using (SqlConnection sqlConn = new SqlConnection(_connectionString))
        {
            DataSet reportAccessInfo = SP_RPT_GET_REPORT_INFO(sqlConn, reportId);
            if (reportAccessInfo != null && reportAccessInfo.Tables.Count > 0 && reportAccessInfo.Tables[0].Rows.Count > 0)
            {
                Uri _reportServerUrl = new Uri(GetReportServer());

                this._reportViewer.ProcessingMode = ProcessingMode.Remote;
                this._reportViewer.SizeToReportContent = true;
                this._reportViewer.ZoomMode = ZoomMode.FullPage;

                DataRow row = reportAccessInfo.Tables[0].Rows[0];
                ServerReport serverReport = this._reportViewer.ServerReport;
                serverReport.ReportServerUrl = _reportServerUrl;                    

                serverReport.ReportPath = (row["reportPath"].ToString().StartsWith("/") ? "" : "/") + row["reportPath"].ToString();                   
                string uriString = row["reportServerPath"].ToString().Trim();
                Uri uri = (Uri)null;
                int num = 0;
                ref Uri local = ref uri;
                if (Uri.TryCreate(uriString, (UriKind)num, out local))
                {
                    serverReport.ReportServerUrl = uri;
                }
                  //Aqui me produce el 401                  
                ReportParameterInfoCollection parameters = this._reportViewer.ServerReport.GetParameters(); 

                if (parameters.Count == 0)
                    this._reportViewer.ServerReport.Refresh();                           

                ViewBag.ReportViewer = this._reportViewer;

                nomInforme = row["reportDesc"].ToString();
            }
        }

        return nomInforme;

    }

为什么某些客户端会出现此错误，我该如何解决？

服务器和客户端在同一个域中。这个问题也无法为我提供解决方案，因为它已经过时了

    添加类ReportServerCredentials并定义如下：

    public class ReportServerCredentials : IReportServerCredentials
    {
        private string _userName;
        private string _password;
        private string _domain;

        public ReportServerCredentials(string userName, string password, string domain)
        {
            _userName = userName;
            _password = password;
            _domain = domain;
        }

        public WindowsIdentity ImpersonationUser
        {
            get
            {
                // Use default identity.
                return null;
            }
        }

        public ICredentials NetworkCredentials
        {
            get
            {
                // Use default identity.
                return new NetworkCredential(_userName, _password, _domain);
            }
        }

        public bool GetFormsCredentials(out Cookie authCookie, out string user, out string password, out string authority)
        {
            // Do not use forms credentials to authenticate.
            authCookie = null;
            user = password = authority = null;
            return false;
        }

    并在函数中调用它：

    serverReport.ReportServerCredentials = new ReportServerCredentials(_user, _password, "");

  2. 根据 Mozilla，这401意味着：

    HTTP 401 错误代码表示请求尚未执行，因为它缺少 所请求资源的有效身份验证凭据。

    因此，您必须将凭据发送到服务器， WWW-Authenticate以便它允许您使用服务或禁用您在 IIS 中配置的身份验证并将其更改为匿名。
