具有C＃中的用户身份验证的cURL

Question

我想在c＃中执行以下cURL请求：

curl -u admin:geoserver -v -XPOST -H 'Content-type: text/xml' \
   -d '<workspace><name>acme</name></workspace>' \
   http://localhost:8080/geoserver/rest/workspaces

我尝试使用WebRequest：

string url = "http://localhost:8080/geoserver/rest/workspaces";
WebRequest request = WebRequest.Create(url);

request.ContentType = "Content-type: text/xml";
request.Method = "POST";
request.Credentials = new NetworkCredential("admin", "geoserver");

byte[] buffer = Encoding.GetEncoding("UTF-8").GetBytes("<workspace><name>my_workspace</name></workspace>");
Stream reqstr = request.GetRequestStream();
reqstr.Write(buffer, 0, buffer.Length);
reqstr.Close();

WebResponse response = request.GetResponse();
...

但出现错误：（400）错误的请求。

如果我更改了请求凭据并在标题中添加了身份验证：

string url = "http://localhost:8080/geoserver/rest/workspaces";
WebRequest request = WebRequest.Create(url);

request.ContentType = "Content-type: text/xml";
request.Method = "POST";
string authInfo = "admin:geoserver";
request.Headers["Authorization"] = "Basic " + authInfo;

byte[] buffer = Encoding.GetEncoding("UTF-8").GetBytes("<workspace><name>my_workspace</name></workspace>");
Stream reqstr = request.GetRequestStream();
reqstr.Write(buffer, 0, buffer.Length);
reqstr.Close();

WebResponse response = request.GetResponse();
...

然后我得到：（401）未经授权。

我的问题是：我应该使用另一个C＃类，例如WebClient还是HttpWebRequest，还是必须对.NET使用curl绑定？

将感谢所有评论或指导。

Answer 1

HTTP Basic身份验证要求将“ Basic”之后的所有内容都进行Base64编码，因此请尝试

request.Headers["Authorization"] = "Basic " + 
    Convert.ToBase64String(Encoding.ASCII.GetBytes(authInfo));

Answer 2

我的问题的解决方案是更改ContentType属性。如果我将ContentType更改为

request.ContentType = "text/xml";

该请求在两种情况下均有效，如果我在上一个示例中也将authInfo转换为Base64String，如建议的[[Anton Gogolev。

Answer 3

使用：

request.ContentType = "application/xml";

request.Credentials = new NetworkCredential(GEOSERVER_USER, GEOSERVER_PASSWD);

也可以。第二套验证信息。

Answer 4

或者，如果您想使用HttpClient：

 var authValue = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(Encoding.UTF8.GetBytes("admin:geoserver")));
        try
        {
            var client = new HttpClient()
            {
                DefaultRequestHeaders = { Authorization = authValue }
            };

            string url = "http://{BASE_URL}";
            client.BaseAddress = new Uri(url);

            var content = new StringContent("<workspace><name>TestTestTest</name></workspace>",
                 Encoding.UTF8, "text/xml");
            var response = await client.PostAsync($"/{PATH_TO_API}/", content);
            response.EnsureSuccessStatusCode();
            var stringResponse = await response.Content.ReadAsStringAsync();
        }
        catch (HttpRequestException ex)
        {
            Console.WriteLine(ex.Message);
        }
