首先看獲取和更新的介面

定義服務端介面,你可以用任意介面都行,我這裡用webapi
獲取檔案列表
1 [HttpGet] 2 public HttpResponseMessage GetUpdaterList(string key) 3 { 4 HttpResult httpResult = new HttpResult(); 5 if (!CheckKey(key)) 6 { 7 httpResult.KeyValue = ""; 8 httpResult.Result = false; 9 httpResult.ErrorMessage = "無許可權訪問"; 10 } 11 else 12 { 13 //獲取printupdate目錄下update.exe的修改日期返回 14 string path = Path.Combine(HttpRuntime.AppDomainAppPath, "printupdate"); 15 StringBuilder strXml = new StringBuilder(); 16 strXml.AppendLine("<?xml version=\"1.0\" encoding=\"utf-8\" ?>"); 17 strXml.AppendLine("<files>"); 18 if (Directory.Exists(path)) 19 { 20 string[] fs = Directory.GetFiles(path, "*.*", SearchOption.AllDirectories); 21 var _p = path.ToLower().Trim().Length + 1; 22 foreach (var item in fs) 23 { 24 var dt = File.GetLastAccessTime(item); 25 strXml.AppendLine("<file time=\"" + dt.ToString("yyyy-MM-dd HH:mm:ss") + "\">" + item.Substring(_p) + "</file>"); 26 } 27 } 28 strXml.AppendLine("</files>"); 29 30 httpResult.KeyValue = strXml.ToString(); 31 httpResult.Result = true; 32 httpResult.ErrorMessage = ""; 33 } 34 return new HttpResponseMessage { Content = new StringContent(httpResult.ToJson(), Encoding.GetEncoding("UTF-8"), "application/json") }; 35 }
下載檔案,我這裡將檔案序列號為base64字串了,你可以直接返回檔案流也行
1 [HttpGet] 2 public HttpResponseMessage DownloadUpdaterFile(string key, string file) 3 { 4 HttpResult httpResult = new HttpResult(); 5 if (!CheckKey(key)) 6 { 7 httpResult.KeyValue = ""; 8 httpResult.Result = false; 9 httpResult.ErrorMessage = "無許可權訪問"; 10 } 11 else 12 { 13 string path = Path.Combine(HttpRuntime.AppDomainAppPath + "printupdate", file); 14 if (!File.Exists(path)) 15 { 16 httpResult.KeyValue = ""; 17 httpResult.Result = false; 18 httpResult.ErrorMessage = "檔案不存在"; 19 } 20 else 21 { 22 httpResult = ConvertToBase64Type(path); 23 } 24 } 25 return new HttpResponseMessage { Content = new StringContent(httpResult.ToJson(), Encoding.GetEncoding("UTF-8"), "application/json") }; 26 27 }
1 HttpResult ConvertToBase64Type(string fileName) 2 { 3 HttpResult httpResult = new HttpResult(); 4 var byts = File.ReadAllBytes(fileName); 5 httpResult.KeyValue = Convert.ToBase64String(byts); 6 return httpResult; 7 }
1 bool CheckKey(string key) 2 { 3 return key == Encryption.Encrypt(m_strkey); 4 }

需要注意的地方:
1、我這裡用到了json,那麼不能直接飲用json的dll檔案,會出現更新時候佔用的問題,可以使用fastjson的開原始碼,放進來解決,你可以直接使用xml格式的返回內容,這樣就不需要json了,這樣更方便
2、如果你的下載介面是返回的檔案流,那麼你更新程式裡面直接接收流儲存檔案就行了
3、Program.cs裡面,停止服務的功能,其實是可以通過傳遞引數的形式來停止,我這裡寫死了,你們根據自己需求修改
效果
你可以根據自己的需求,修改下介面效果,這是最簡單的示例介面而已。
