+# 初赛一级赛题3：基于矽璓已实现的Lwip，在ARM上实现FTP协议的Client功能
+
+## 1. 简介
+本项目是基于矽璓已实现的Lwip，在ARM上实现FTP协议的Client功能
+test_ftpclient.h声明了下载10个文件的测试函数
+test_ftpclient.c实现了下载10个文件的测试函数
+ftp_client文件夹定义了ftp_client的相关类库其中my_socket.h,my_socket.c定义了socket抽象层，并基于
+Lwip实现了该抽象层，ftp_client.h,ftp_client.c实现了ftp登录，获取文件大小，下载文件等功能
+
+## 2. 数据结构设计说明
+- ftp_client.c 的设计
+分别定义了发送命令和接收数据的socket和相应的缓冲区并且实现了登录、发送命令、接收响应数据、查找文件大小、进入被动模式、下载文件、关闭ftp客户端等操作
+```c
+static int  m_socket_cmd; // 发送命令的socket文件描述符
+static int  m_socket_data; // 接收ftp服务器文件的socket文件描述符
+static char m_send_buffer[1024]; // 发送缓冲区
+static char m_recv_buffer[1024];  // 接收缓冲区
+```
+## 3. 测试程序说明
+- test_ftpclient.c用于测试下载10个文件
+连接电脑上的ftp服务器下载10个4KB文件,通过终端日志打印确定文件是否下载成功，以及追踪通信流程和下载进度
+```c
+void TestFtpClient(int argc, char* argv[])
+{
+    FtpInitCmd();
+    int ret = FtpLogin("192.168.0.248", 21, "anonymous", "anonymous");
+    int size;
+    char *buf;
+    for(int i = 1;i <= 10;i++){
+        char fileName[20] = "/file"; 
+        char temp[5] = "";
+        sprintf(temp,"%d",i);
+        strcat(fileName,temp);
+        size = FtpFileSize(fileName);
+        buf = malloc(size);
+        FtpInitData();  // data socket 每次下载都要重新创建，下载完都要关闭
+        ret = FtpDownload(fileName, buf, size);
+        free(buf);
+    }
+    FtpQuit();
+    return;
+}
+```
+
+## 4. 运行结果（##需结合运行测试截图按步骤说明##）
+1. 配置开启BSP_USING_LWIP、USER_TEST_FTPCLIENT
