python作業高級FTP（第八周）

作業需求：

1. 用戶加密認證

2. 多用戶同時登陸

3. 每個用戶有自己的家目錄且只能訪問自己的家目錄

4. 對用戶進行磁盤配額、不同用戶配額可不同

5. 用戶可以登陸server后，可切換目錄

6. 查看當前目錄下文件

7. 上傳下載文件，保證文件一致性

8. 傳輸過程中現實進度條

9. 支持斷點續傳

思路分析：

上一個簡單服務器的升級版本，先一個版本鏈接：http://www.cnblogs.com/sean-yao/p/7772159.html，在原有代碼中，重構并實現9個需求，提升程序健壯性：

更新如下：

1. FTP數據存儲目錄，使用相對路徑，提升遷移性。

2. FTP在上傳下載的時候有粘包處理，其他命令如ls，pls等也做了粘包處理。

3.增加了ConnectionResetError，Exception，UnicodeDecodeError，socket.error等異常處理。

對于高級FTP需求：

1. 用hashlib加密用戶輸入的密碼讓Server保存Md5值，實現簡單認證加密。

2. 多用戶同時登陸使用socketserver模塊（上一版本已經實現），控制線程并發多用戶同時登陸和操作。

3. 創建用戶時候將密碼文件FTP目錄，相對路徑寫到密碼文件中，認證成功后可以調用相對路徑，然后使用OS模塊的os.chdir($dir)進行切換用戶家目錄操作。

4. 用random函數隨機一個512M-1024M之間的磁盤配額，(用戶剩余空間 = 限額 - 家目錄總文件大小)對比文件大小就可以進行磁盤配額的操作。

5. 用戶操作使用cd命令，可以切換到家目錄的任意目錄（前一版本已經實現）。

6.?通過ls查看家目錄下的二級目錄三級目錄等文件（前一版本已經實現）。

7.?上傳下載文件，保證文件一致性使用hashlib，讓服務端傳送客戶端進行校驗。

8.?傳輸過程中現實進度條上傳和下載的進度條都已經完成，使用progressbar模塊。

9. 斷點續傳，創建臨時文件，客戶端上傳時，服務器檢查臨時文件，有就發大小發給客戶端，客戶端seek到文件斷點處給服務器端發送數據。

代碼示例：

　　此次作業是以上一個版本代碼做的重構http://www.cnblogs.com/sean-yao/p/7772159.html，所以這里只放入新增加的部分包含ftp_client.py，ftp_server.py，total_size_class.py，auth.py

作者:yaobin
版本:高級Ftp示例版本 v0.2
開發環境: python3.6程序介紹:1. 用戶加密認證
2. 多用戶同時登陸
3. 每個用戶有自己的家目錄且只能訪問自己的家目錄
4. 對用戶進行磁盤配額、不同用戶配額可不同
5. 用戶可以登陸server后，可切換目錄
6. 查看當前目錄下文件
7. 上傳下載文件，保證文件一致性
8. 傳輸過程中現實進度條
9. 支持斷點續傳使用說明:
1.可以在Linux和Windows都可以運行
2.Linux調用了cd,mkdir,ls,rm,命令
3.Windows調用了cd,md,dir,del,命令
