# 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
- mysocket.c 设计介绍
设计socket抽象层，分别需要实现socket的创建、连接、发送数据、接收数据和关闭等操作
```c
#include "my_socket.h"
#include <sockets.h>
#include <def.h>
int SocketCreate(void){
return socket(AF_INET,SOCK_STREAM,0);
}
int SocketConnect(int sock, const char *addr, int port){
unsigned int iRemoteAddr = 0;
struct sockaddr_in stRemoteAddr = {0}; //对端，即目标地址信息
stRemoteAddr.sin_len = htons(sizeof(AF_INET));
stRemoteAddr.sin_family = AF_INET;
stRemoteAddr.sin_port = htons(port);
inet_pton(AF_INET, addr, &iRemoteAddr);
stRemoteAddr.sin_addr.s_addr=iRemoteAddr;
return connect(sock,(void *)&stRemoteAddr,sizeof(stRemoteAddr)) == 0 ? 1 : 0;
}
int SocketSend(int sock, void *data, int len){
return send(sock,data,len,0);
}
int SocketRecv(int sock, void *data, int len){
return recv(sock,data,len,0);
}
void SocketClose(int sock){
close(sock);
}
```
- 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
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "my_socket.h"
#include "ftp_client.h"

if(ret != 150)
{
SocketClose(m_socket_data);
return 0;
}
//开始下载,读取完数据后，服务器会自动关闭连接
for(i=0; i<len; i+=ret)
{
ret = SocketRecv(m_socket_data, ((char *)buf) + i, len);
printf("download %d/%d.\r\n", i + ret, len);
if(ret < 0)
{

break;
}
}
//下载完成

fwrite(buf,len,1,fp);
fclose(fp);
SocketClose(m_socket_data);
ret = FtpRecvRespond(m_recv_buffer, 1024);
return (ret==226);
}
int FtpFileSize(char *name)
{

int FtpLogin(char *addr, int port, char *username, char *password)
{

return 0;
}
return 1;
}
void FtpQuit(void)
{
FtpSendCommand("QUIT\r\n");
SocketClose(m_socket_cmd);
}
void FtpInitCmd(void)
{
m_socket_cmd = SocketCreate();
}
void FtpInitData(void){
m_socket_data= SocketCreate();
}
```
## 3. 测试程序说明
- test_ftpclient.c用于测试下载10个文件
```c
/* test for ftp client */
#include "test_ftpclient.h"
#include "ftp_client/ftp_client.h"
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <transform.h>
void TestFtpClient(int argc, char* argv[])
{
FtpInitCmd();
int ret = FtpLogin("192.168.80.31", 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;
}
PRIV_SHELL_CMD_FUNCTION(TestFtpClient, a ftpClient test sample, PRIV_SHELL_CMD_MAIN_ATTR);
```
## 4. 运行结果（##需结合运行测试截图按步骤说明##）
1. 设置ip
2. 运行TestFtpClient，开始下载文件
