新日程
这两天主板烧了,所以也没啥过多进度,也就把文件服务器模块设计并解决了,项目各个模块处理完之后顺便把流程图画了。 在做文件服务器模块的时候我发现好多功能和数据库服务器相交了,搞得我有点乱,而且协议改来改去,有些文件也是多模块共用,搞得我都晕了,所以我决定接下来重构。
新甘特图已经备好:
上期日报
来我们看看有多少人坚持下来了:
1号 | 日报7 |
---|---|
8号 | 日报6 |
稍微有点尴尬。。。 应该是忙着赶进度,我这速度是有点飘,所以上天就让我主板烧了躺床上去歇着了吧。
我的进度
预期计划
文件服务器模块解决。
实际情况
解决了。
FTP服务器流程图
FTP操作图
简单放一些零件基类代码,这个后期也要封装成动态库,不面向用户。
代码语言:javascript复制//FileBase.h

#include<stdio.h> // printf
#include<stdlib.h> // exit
#include<string.h> // bzero

class FileBase
{
public:
void addFile(char* file_name, int client_socket_fd); //上传文件
int CreateDir(const char* sPathName); //新增目录
void delFile(char* filename); //删除文件
void delDir(char* filename); //删除目录
// void serchDir();查找目录 这个是属于数据库的事情,应该放在包里直接传过来。然后包做一个对内包,不用跟客户端对接的内部协议
void serchlist(char* basePath, char* ret);//查找列表
void serchmode(char* filename);//查找权限
void modDir(const char* old_path, const char* new_path); //修改目录
// void modMode(const char* path, mode_t mode); //权限留在数据库,我才不管
void downFile(char* file_name, int new_server_socket_fd);//下载文件
int connect_to_client();
};
可以看出来其实很多功能当时我是比较纠结放在哪个服务器实现的。

具体调用就那么用咯。
重构·整体流程
图太长了,截不下来,我就左右分了。
下一工作日任务
重构,将可以封装在动态库里的封装在动态库里,将不能封装在动态库里的,改好之后封装到动态库。 那么,第一步,前置服务器的封装,理想情况是只放出场景类来,GoGoGo!!!
