想自己写个客户端，模拟浏览器向服务器(如lighttpd等)上传数据。用HTTPrequest抓了包，以下为发送的数据内容：

引用

POST /upload.php HTTP/1.0

Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/vnd.ms-excel, application/msword, application/vnd.ms-powerpoint, */*

Accept-Language: en-us

Accept-Encoding: gzip, deflate

User-Agent: Mozilla/4.0

Content-Length: 180

Host: 192.168.1.180

Content-Type: application/x-www-form-urlencoded

-----------------------------7d93a924b05a2

Content-Disposition: form-data; name="upload_file"; filename="C:\tmp\hello.txt"

Content-Type: text/plain

在实现时，代码大致如下：

#include

#include

#include

#include

#include

// post a big file

#define Req "POST /upload.php HTTP/1.0\r\n"\

"Accept:image/gif, image/x-xbitmap, image/jpeg, image/pjepg, application/vnd.ms-excel, application/msword, applicationvnd.ms-powerpoint, */*\r\n"\

"Accept-Language:en-us\r\n"\

"Accept-Encoding:gzip, deflate\r\n"\

"User-Agent:Mozilla/4.0\r\n"\

"Host:192.168.1.180\r\n"\

"Content-Type:application/x-www-urlencoded\r\n"\

"-----------------------------7d91a515b05a2\r\n"\

"Content-Disposition:form-data;name=\"upload_file\";filename=\"tmp.gz\"\r\n"\

"Content-Type:application/x-gzip\r\n"

#define DST_IP "192.168.1.180"

#define ReqLen sizeof(Req)

int main()

{

struct sockaddr_in srv;

int sock, nbytes;

char sndbuf[1024] = {0};

char recbuf[1024] = {0};

if((sock = socket(AF_INET, SOCK_STREAM, 0)) == -1)

{

fprintf(stderr, "socket() error!\n");

exit(1);

}

srv.sin_family = AF_INET;

srv.sin_addr.s_addr = inet_addr(DST_IP);

srv.sin_port = htons(80);

if((connect(sock, (struct sockaddr *)&srv, sizeof(struct sockaddr))) == -1)

{

printf("connect() error!\n");

exit(1);

}

strncpy(sndbuf, Req, ReqLen);

if(write(sock, sndbuf, ReqLen) == -1)

{

fprintf(stderr, "write() error!\n");

exit(1);

}

// get response

int bytes;

while(1)

{

nbytes = read(sock, recbuf, 1023);

if(nbytes < 0)

break;

recbuf[nbytes] = '\0';

printf(recbuf);

}

close(sock);

return 0;

}

先怀疑对HTTP请求的数据封装的格式不对，每次运行client，总会提示400-bad request!这样的错误～～

原本的目标是向lighttpd服务器上传数据(文件较大，一般不小于1G)，然后在服务器自己写个cgi来接受/处理数据。现在对上传这部分很头大，看了好久http协议了～～

不知道有没有更好的方法～～ 请路过的各位大侠多多指教～～ 谢过～～
