// 参数1为服务器与该客户端之间的缓存区对象，参数2为客户端发送的信息 54 | 55 | - 首先连接上user数据库，chatdb->my_database_connect("user"); 56 | 57 | - 判断注册用户是否已经存在，chatdb->my_database_user_exist(val["user"].asString())) 58 | 59 | - 若已经存在，回复客户端注册失败； 60 | 61 | - 若不存在，执行以下函数，将注册用户的用户名和密码，加入到user数据库中；然后回复客户端注册成功。 62 | 63 | ```c++ 64 | chatdb->my_database_user_password(val["user"].asString(), val["password"].asString()); 65 | ``` 66 | 67 | - 关闭user数据库，chatdb->my_database_disconnect(); 68 | 69 | ### 1.6 实现用户登录功能 70 | 71 | - 首先连接上user数据库，最后再断开连接，同上，接下来涉及到访问user数据库，均需要这两步，不再赘述； 72 | 73 | - 判断登录用户是否已经存在于user数据库中： 74 | 75 | - 若不存在，回复客户端该登录用户不存在； 76 | 77 | - 若存在，判断用户登录密码是否正确: 78 | 79 | ```c++ 80 | chatdb->my_database_password_correct(val["user"].asString(), 81 | val["password"].asString() 82 | ``` 83 | 84 | - 若不正确，回复客户端，输入登录失败，密码不正确，将登录函数结束掉return 85 | 86 | - 若正确： 87 | 88 | - 向在线用户链表中加入该登录用户，chatlist->online_user->push_back(u); 89 | 90 | - 获取该登录用户好友friend_list和群聊列表group_list并且返回给客户端，便于qt客户端开发时，显示登录用户的好友和群聊列表，以实现接下来的好友上线提醒、聊天等功能； 91 | 92 | ``` 93 | chatdb->my_database_get_friend_group(val["user"].asString(), friend_list, group_list) 94 | ``` 95 | 96 | - 登录成功后，向该登录用户的所有在线好友，发送自己上线的提醒：遍历friend_list，与 chatlist->online_user的一一匹配，若某好友在线，则向其bev/客户端发送自己上线的提醒 97 | 98 | ### 1.7 实现添加好友功能 99 | 100 | - 首先判断用户user——小明将要添加的好友friend小华——是否存在于用户数据库中 101 | 102 | - 若不存在，回复用户小明，你要添加的好友小华不存在，添加好友操作结束return 103 | 104 | - 若存在，再判断两人是否已经是好友关系 105 | 106 | ```c++ 107 | chatdb->my_database_is_friend(val["user"].asString(), val["friend"].asString()) 108 | ``` 109 | 110 | - 若已经是好友关系，回复用户小明，你与添加的好友小华已经是好友关系，添加好友操作结束return 111 | 112 | - 若还不是好友关系： 113 | 114 | - 修改双方的用户表的friend好友字符串，互相添加为好友（注意，此处未考虑好友验证通过的功能，后期优化再实现）； 115 | 116 | ```c++ 117 | chatdb->my_database_add_new_friend(val["user"].asString(), val["friend"].asString()); 118 | chatdb->my_database_add_new_friend(val["friend"].asString(), val["user"].asString()); 119 | ``` 120 | 121 | - 回复执行添加好友的用户小明，添加好友成功 122 | - 遍历在线用户链表，判断添加的好友小华是否在线，若在线，回复小华，小明已将你添加为好友。 123 | 124 | ### 1.8 实现创建群聊功能 125 | 126 | * 首先连接上`chatgroup`数据库，使用结束再断开连接，接下来涉及到访问`chatgroup`数据库，均需要这两步，不再赘述； 127 | 128 | * 判断群是否已存在`chatdb->my_database_group_exist(val["group"].asString())` 129 | 130 | * 若已经存在，回复客户端用户，该群已存在 131 | 132 | * 若不存在， 133 | 134 | * 在`chatgroup`中创建该群聊，初始化群聊名，群主，群成员信息 135 | 136 | ```c++ 137 | chatdb->my_database_add_new_group(val["group"].asString(), val["user"].asString()) 138 | ``` 139 | 140 | * 在`user`中，将新建群聊加入到创建该群聊用户的群聊字符串中 141 | 142 | ```c++ 143 | chatdb->my_database_user_add_group(val["user"].asString(), val["group"].asString()); 144 | ``` 145 | 146 | * 将新建群聊加入到群信息链表中 147 | 148 | ```C++ 149 | chatlist->info_add_new_group(val["group"].asString(), val["user"].asString()); 150 | ``` 151 | 152 | * 回复客户端用户，群聊创建成功 153 | 154 | ### 1.9 添加群聊 `server_add_group` 155 | 156 | * 首先判断该群聊是否存在于`chatgroup`数据库中 157 | 158 | * 如果不存在，回复客户端用户，你要添加的群聊不存在，`return`； 159 | 160 | * 如果存在，判断该用户是否已经在该群聊中，此时使用群聊信息链表，访问速度相比于数据库更快 161 | 162 | ```C++ 163 | chatlist->info_user_in_group(val["group"].asString(), val["user"].asString()) 164 | ``` 165 | 166 | * 如果该用户已经存在于该群聊中，回复客户端用户，你已经存在于该群聊中，`return`； 167 | 168 | * 若不在该群聊中 169 | 170 | * 在`user`中，将该群聊加入到该用户的群聊字符串中； 171 | 172 | 在`chatgroup`中，将该用户加入到该群聊的群成员字符串中； 173 | 174 | * 修改群聊信息链表，将该用户加入到该群聊节点的群成员链表中； 175 | 176 | ```c++ 177 | chatlist->info_group_add_user(val["group"].asString(), val["user"].asString()); 178 | ``` 179 | 180 | * 回复客户端用户，添加群聊成功 181 | 182 | ### 1.10 私聊 `server_private_chat` 183 | 184 | * 首先判断好友是否在线————遍历在线用户链表，获得其缓存区对象`to_bev` 185 | 186 | ```c++ 187 | struct bufferevent* to_bev = chatlist->info_get_friend_bev(val["user_to"].asString()); 188 | ``` 189 | 190 | * 如果`NULL == to_bev`,说明好友不在线，回复发送方，return 191 | * 如果好友在线，将发送方用户缓存区对象bev中的内容val转换为字符串s，再转发给好友的缓存区对象to_bev，再回复发送方，私聊发送成功。 192 | 193 | ### 1.11 群聊 `server_group_chat` 194 | 195 | * 首先遍历群聊信息链表找到该群聊 196 | * 遍历该群聊的群成员链表 197 | * 遍历在线用户链表，找到每个群成员（包括发送方自己）的缓存区对象`to_bev`,若不为空，转发发送方的bev，最后回复发送方，群聊发送成功 198 | 199 | ### 1.12 获取群聊成员 `server_get_group_member` 200 | 201 | * 遍历群聊信息链表，获取某群聊的群聊成员字符串member，将其返回给调用该函数的客户端 202 | 203 | ```c++ 204 | string member = chatlist->info_get_group_member(val["group"].asString()); 205 | ``` 206 | 207 | ### 1.13 用户下线 `server_user_offline` 208 | 209 | * 首先从用户在线链表`online_user`中删除该用户 210 | * 获取该用户好友friend_list 211 | * 向在线好友，发送该用户的下线提醒 212 | 213 | ### 1.14 发送文件 server_send_file 214 | 215 | * 首先判断对方是否在线 216 | 217 | * 若不在线，回复发送方，接收方不在线，return； 218 | 219 | * 若在线： 220 | 221 | * 启动新线程，创建文件服务器，处理该文件传输任务（不影响聊天等功能）,引用方式获得发送方客户端和接收方客户端相对于文件服务器的fd 222 | 223 | ```c++ 224 | thread send_file_thread(send_file_handler, val["length"].asInt(), port, &from_fd, &to_fd);
