Exemplos

O código de exemplo a seguir mostra um método para obter e definir o cabeçalho HTTP de Autorização em um objeto HttpRequestMessage usando as propriedades e métodos na classe HttpCredentialsHeaderValue.

using System;
using Windows.Web.Http;
using Windows.Web.Http.Headers;

        public void DemonstrateHeaderRequestAuthorization() {
            var request = new HttpRequestMessage();

            // Set the header with a strong type.
            string username = "user";
            string password = "password";
            var buffer = Windows.Security.Cryptography.CryptographicBuffer.ConvertStringToBinary (username + ":" + password, Windows.Security.Cryptography.BinaryStringEncoding.Utf16LE);
            string base64token = Windows.Security.Cryptography.CryptographicBuffer.EncodeToBase64String(buffer);
            request.Headers.Authorization = new HttpCredentialsHeaderValue("Basic", base64token);


            // Get the strong type out
            System.Diagnostics.Debug.WriteLine("One of the Authorization values: {0}={1}", 
                request.Headers.Authorization.Scheme,
                request.Headers.Authorization.Token);

            // The ToString() is useful for diagnostics, too.
            System.Diagnostics.Debug.WriteLine("The Authorization ToString() results: {0}", request.Headers.Authorization.ToString());
        }

O código de exemplo a seguir mostra um método para obter e definir o cabeçalho HTTP Proxy-Authorization em um objeto HttpRequestMessage usando as propriedades e métodos na classe HttpCredentialsHeaderValue.

using System;
using Windows.Web.Http;
using Windows.Web.Http.Headers;

        public void DemonstrateHeaderRequestProxyAuthorization() {
            var request = new HttpRequestMessage();

            // Set the header with a strong type.
            string username = "user";
            string password = "password";
            var buffer = Windows.Security.Cryptography.CryptographicBuffer.ConvertStringToBinary(username + ":" + password, Windows.Security.Cryptography.BinaryStringEncoding.Utf16LE);
            string base64token = Windows.Security.Cryptography.CryptographicBuffer.EncodeToBase64String(buffer);
            request.Headers.ProxyAuthorization = new HttpCredentialsHeaderValue("Basic", base64token);


            // Get the strong type out
            System.Diagnostics.Debug.WriteLine("One of the ProxyAuthorixation values: {0}={1}",
                request.Headers.ProxyAuthorization.Scheme,
                request.Headers.ProxyAuthorization.Token);

            // The ToString() is useful for diagnostics, too.
            System.Diagnostics.Debug.WriteLine("The ProxyAuthorization ToString() results: {0}", request.Headers.ProxyAuthorization.ToString());
        }

Comentários

A classe HttpCredentialsHeaderValue representa o cabeçalho HTTP autorização ou autorização de proxy em uma solicitação HTTP.

A propriedade Authorization no HttpRequestHeaderCollection retorna um objeto HttpCredentialsHeaderValue que representa o cabeçalho HTTP authorization . A propriedade ProxyAuthorization no HttpRequestHeaderCollection retorna um objeto HttpCredentialsHeaderValue que representa o cabeçalho HTTP Proxy-Authorization .
