如何从WCF服务获取数据？ [英] How to get a data from the WCF service?

问题描述

例如，



i有一个WCF服务：

http://team.abc.net/site/DSP/培训/ _bin / LinkData.svc



来自这项服务我必须得到数据。我使用了以下代码，但它的抛出错误为未授权。



我也不知道如何通过uri对象传递用户名和密码，我试过uri建设者班也。但同样的问题。



请做必要的事情。



我尝试了什么：



1st我在解决方案中将服务引用添加为'TrainingLinkService'。

For Example,

i have a WCF service as:
http://team.abc.net/site/DSP/Training/_bin/LinkData.svc

from this service i have to get the data. i used the following code, but its throwing error as 'unauthorized'.

Also im not sure how to pass the username and password with the uri object, i tried with uri builder class also. but same problem.

Please do the needful.

What I have tried:

1st i added the service reference in solution as 'TrainingLinkService'.

var uri = new Uri("http://team.abc.net/site/DSP/Training/_bin/LinkData.svc");
TrainingLinkService.TrainingProgramReviewDataContext client = new TrainingLinkService.TrainingProgramReviewDataContext(uri);
var temp = from item in container.Documentation
            select item;

推荐答案

以下是解决方案：它是Atom格式，所以我有点困惑解析它。

Here is the solution: it was in Atom format, so i was bit confused to parse it.

static List<DocumentationEntity> ParseAtom(string url, string username, string password)
        {
            try
            {
                var _xDocument = new XDocument();
                var _Request = WebRequest.Create(url) as HttpWebRequest;
                    _Request.Method = "GET";
                    _Request.Credentials = new NetworkCredential(username, password);
                    
                using (HttpWebResponse response = _Request.GetResponse() as HttpWebResponse)
                {
                    using (Stream stream = response.GetResponseStream())
                    {
                        _xDocument = XDocument.Load(stream);
                    }
                }

                var entries = from root in _xDocument.Root.Elements().Where(i => i.Name.LocalName == "entry")
                              from entry in root.Elements().Where(i => i.Name.LocalName == "properties")
                              select new DocumentationEntity
                              {
                                  ContentTypeID = entry.Elements().First(i => i.Name.LocalName == "ContentTypeID").Value,

                                  ScriptCompleted = entry.Elements().First(i => i.Name.LocalName == "ScriptCompleted").Value,
                                  Id = entry.Elements().First(i => i.Name.LocalName == "Id").Value,

                                  Modified = entry.Elements().First(i => i.Name.LocalName == "Modified").Value,
                                  ModifiedById = entry.Elements().First(i => i.Name.LocalName == "ModifiedById").Value,
                                  CopySource = entry.Elements().First(i => i.Name.LocalName == "CopySource").Value,
                                  ApprovalStatus = entry.Elements().First(i => i.Name.LocalName == "ApprovalStatus").Value,
                                  Path = entry.Elements().First(i => i.Name.LocalName == "Path").Value,

                                  Owshiddenversion = entry.Elements().First(i => i.Name.LocalName == "Owshiddenversion").Value,
                                  Version = entry.Elements().First(i => i.Name.LocalName == "Version").Value
                              };
                return entries.ToList();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
                throw ex;
            }
        }
