webclient 401 转换为 c#

我在使用网络客户端时遇到一些问题。

当我尝试时：

var client = new WebClient();
client.Credentials = new NetworkCredential("intranet.homolog", "S3br@32011", "na-sebrae");
var html = client.DownloadData("http://www.intranet.sebrae.com.br/noticias/todas-as-notícias/rss.aspx?estado=");

我收到错误（401）。

该 url 返回 xml feed，当我在浏览器中访问它时，我可以正常登录。

该用户和密码是真实的。

有人有一些想法可以让我使用网络客户端访问它吗？

I'm have some problems to use webclient.

When I try it:

var client = new WebClient();
client.Credentials = new NetworkCredential("intranet.homolog", "S3br@32011", "na-sebrae");
var html = client.DownloadData("http://www.intranet.sebrae.com.br/noticias/todas-as-notícias/rss.aspx?estado=");

I get an error (401).

This url returns xml feed, and, when I access it into browser, I login normally.

This user, and password are real.

Somebody have some ideia to I access it with the webclient?

我的猜测是：您误用了 NetworkCredential 构造函数。

正确的语法是

public NetworkCredential(
    string userName,
    string password,
    string domain
)

首先是用户名，然后是密码，然后是域 - 您的语法全错了。

请尝试以下操作：

var client = new WebClient();
client.Credentials = new NetworkCredential("na-sebrae", 
                                           "S3br@32011",  "intranet.homolog");
var html = client.DownloadData("http://www.intranet.sebrae.com.br" +
                               "/noticias/todas-as-notícias/rss.aspx?estado=");

Here's my guess: you're misusing the NetworkCredential constructor

The correct syntax is

public NetworkCredential(
    string userName,
    string password,
    string domain
)

First username, then password, then domain - you got yours all wrong.

Try the following:

var client = new WebClient();
client.Credentials = new NetworkCredential("na-sebrae", 
                                           "S3br@32011",  "intranet.homolog");
var html = client.DownloadData("http://www.intranet.sebrae.com.br" +
                               "/noticias/todas-as-notícias/rss.aspx?estado=");

我也遇到同样的错误。相同的链接在浏览器中效果更好，但为 WebClient 提供 401 异常。

    string url = "http://www.intranet.sebrae.com.br/noticias/todas-as-notícias/rss.aspx?estado=";
    var webClient = new WebClient();

    webClient.Credentials = CredentialCache.DefaultCredentials;

    byte[] html = webClient.DownloadData(fileAbsoluteUri);

I too get same error. The same link work better in browser but but giving 401 exception for WebClient.

    string url = "http://www.intranet.sebrae.com.br/noticias/todas-as-notícias/rss.aspx?estado=";
    var webClient = new WebClient();

    webClient.Credentials = CredentialCache.DefaultCredentials;

    byte[] html = webClient.DownloadData(fileAbsoluteUri);
