Question

我正在尝试将XML发布到REST服务。这是我正在使用的代码：

我在调用服务时遇到以下错误。

远程服务器返回错误：（401）未经授权。

我也尝试过直接设置NetworkCredentials，即

NetworkCredential nc = new NetworkCredential(username, password);
serviceRequest.Credentials = nc;

感谢您的帮助。

Uri address = new Uri("https://localhost:30000/restservice/");

// Create the web request  
HttpWebRequest request = WebRequest.Create(address) as HttpWebRequest;

// Set type to POST  
request.Method = "POST";
request.ContentType = "application/json";

string data = @"<Sample XML Here>";

// Create a byte array of the data we want to send  
byte[] byteData = UTF8Encoding.UTF8.GetBytes(data);

// Set the content length in the request headers  
request.ContentLength = byteData.Length;

// Write data  
using (Stream postStream = request.GetRequestStream())
{
    postStream.Write(byteData, 0, byteData.Length);
}

string usernamePassword = username + ":" + password;

CredentialCache mycache = new CredentialCache();

mycache.Add(address, "Basic", new NetworkCredential(username, password));
request.Credentials = mycache;

// Get response  
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
    // Get the response stream  
    StreamReader reader = new StreamReader(response.GetResponseStream());

    // Console application output  
    Response.Write(reader.ReadToEnd());
}

Answer 1

要尝试的事情：

更改内容类型，因为您没有向其发布json
不将数据编码为期望的xml，而不是二进制流

希望这有帮助。

Answer 2

使用Fiddler并查看从服务器返回的WWW-Authenticate标头。这将告诉您服务器支持哪种身份验证方案。

Answer 3

尝试在此请求中设置凭据

request.Credentials = new NetworkCredential(username, password);

将XML发布到REST时发生HTTP 401错误
