安装OpenFire服务器略去
1.安装User Service插件：
在管理控制平台找到选项卡“插件”，里边有我们需要安装的一个User Service插件，如果安装过了会显示已经安装的哪些插件，没有安装，需要点击左侧菜单“有效的插件”，在列表里找到此插件进行安装，可能有点慢，稍等即可。如果在有效的插件列表没有发现很多的插件，那么你需要重新安装openfire服务器或者升级最新版本。
2：
在选项卡“服务器”找到“服务器设置”下有个菜单“User Service”，说明安装插件成功，但是还是需要进行设置才能通过端口进行访问，不然无法访问或者报错401未授权等。设置：Enabled - User service requests will be processed. 启用、勾选HTTP basic auth - User service REST authentication with Openfire admin account. 如果选择Secret key auth，那C#写着太麻烦，通过访问接口需要传Secret key的值，否则就是报错401。
还可以在系统属性里添加进行设置接口是否启用，需要设置2项值如下图：
3：然后就可以通过C#代码进行访问接口，获取所有的用户列表：
/// <summary> /// 获取所有openfire用户 /// </summary> /// <returns></returns> public ActionResult Index() {
//这个地方的地址和用户名密码我是从配置文件读取的，大家可以直接赋值。 string url = CachedConfigContext.Current.SettingConfig.OpenFireServer + "plugins/userService/users"; WebRequest req = WebRequest.Create(url); req.Method = "GET"; string username = CachedConfigContext.Current.SettingConfig.OpenFireUsername; string password = CachedConfigContext.Current.SettingConfig.OpenFirePassword; string usernamePassword = username + ":" + password; CredentialCache mycache = new CredentialCache(); mycache.Add(new Uri(url), "Basic", new NetworkCredential(username, password)); req.Credentials = mycache; req.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(new ASCIIEncoding().GetBytes(usernamePassword))); WebResponse result = null; try { result = req.GetResponse(); Stream ReceiveStream = result.GetResponseStream(); //read the stream into a string StreamReader sr = new StreamReader(ReceiveStream); string resultstring = sr.ReadToEnd(); if (!string.IsNullOrEmpty(resultstring)) { XmlDocument doc = new XmlDocument(); doc.LoadXml(resultstring); var xmlModel = XmlToObjList<OpenFireUser>(resultstring, "user"); this.ViewBag.existUsers = string.Join(",", xmlModel.Select(s => s.username)); return View(xmlModel); } } catch (Exception exp) { } finally { if (result != null) { result.Close(); } } return View(); } /// <summary> /// xml文件转化为实体类列表 /// </summary> /// <typeparam name="T">实体名称</typeparam> /// <param name="xml">您的xml文件</param> /// <param name="headtag">xml头文件</param> /// <returns>实体列表</returns> public List<T> XmlToObjList<T>(string xml, string headtag) where T : new() { List<T> list = new List<T>(); XmlDocument doc = new XmlDocument(); PropertyInfo[] propinfos = null; doc.LoadXml(xml); //XmlNodeList nodelist = doc.SelectNodes(headtag); XmlNodeList nodelist = doc.GetElementsByTagName(headtag); foreach (XmlNode node in nodelist) { T entity = new T(); //初始化propertyinfo if (propinfos == null) { Type objtype = entity.GetType(); propinfos = objtype.GetProperties(); } //填充entity类的属性 foreach (PropertyInfo propinfo in propinfos) { //实体类字段首字母变成小写的 string name = propinfo.Name.Substring(0, 1) + propinfo.Name.Substring(1, propinfo.Name.Length - 1); XmlNode cnode = node.SelectSingleNode(name); if (cnode != null) { string v = cnode.InnerText; if (v != null) propinfo.SetValue(entity, Convert.ChangeType(v, propinfo.PropertyType), null); } } list.Add(entity); } return list; }
最后会返回一个xml的文件，里边是所有用户的信息。
至于新增、删除的接口就不做案例里，你可以通过管理控制平台查找demo，里边有介绍如何访问接口，查看地址：http://192.168.3.66:9090/plugin-admin.jsp?plugin=userservice&showReadme=true&decorator=none
如下图点击图标就可以查看此插件的demo：
通过User Service添加用户：
[HttpPost] public JsonResult syncUser(string existUsers) { if (!string.IsNullOrEmpty(existUsers)) { var array = existUsers.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries); var Users = this.FoundationService.GetPersonMain(s => s.UnitID == this.CurrentManager.UnitID); foreach (var item in Users) { if (array.Contains(item.UserName.ToLower())) { continue; } var userXML = string.Format("<?xml version='1.0' encoding='UTF-8' standalone='yes'?> <user> <username>{0}</username> <password>{1}</password> <name>{2}</name> <email>{3}</email></user>", item.UserName, item.Password, item.PersonName, item.Email); //通过openFire user service添加用户 string url = CachedConfigContext.Current.SettingConfig.OpenFireServer + "plugins/userService/users"; WebRequest req = WebRequest.Create(url); req.Method = "POST"; string username = CachedConfigContext.Current.SettingConfig.OpenFireUsername; string password = CachedConfigContext.Current.SettingConfig.OpenFirePassword; string usernamePassword = username + ":" + password; CredentialCache mycache = new CredentialCache(); mycache.Add(new Uri(url), "Basic", new NetworkCredential(username, password)); req.Credentials = mycache; req.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(new ASCIIEncoding().GetBytes(usernamePassword))); req.ContentType = "application/xml"; byte[] byteArray = Encoding.UTF8.GetBytes(userXML); req.ContentLength = byteArray.Length; Stream dataStream = req.GetRequestStream(); dataStream.Write(byteArray, 0, byteArray.Length); dataStream.Close(); WebResponse result = null; try { result = req.GetResponse(); Stream ReceiveStream = result.GetResponseStream(); //read the stream into a string StreamReader sr = new StreamReader(ReceiveStream); string resultstring = sr.ReadToEnd(); } catch (Exception exp) { return Json(new { success = false, msg = "同步失败！" + exp.Message }); } finally { if (result != null) { result.Close(); } } } } return Json(new { success = true, msg = "同步成功！" }); }
