我在我的C ++项目中使用winsocket代码的一个简单片段,试图从共享主机上的文件中提取数据(host-ed.me)。我的winsocket代码如下:
void write(string file, string text) {
ofstream os;
os.open(file, ofstream::app);
text += "\n";
os.write(text.c_str(), text.size());
os.close();
}
bool request() {
WSADATA wsa;
SOCKET s;
struct sockaddr_in server;
char server_reply[4096];
int recv_size;
// initialize winsockets
if (WSAStartup(MAKEWORD(2,2), &wsa) != 0) {
write("log.txt", "winsockets initialization - error!");
return false;
}
// open a socket
if ((s = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP)) == INVALID_SOCKET) {
write("log.txt", "socket opening - error!");
return false;
}
// connect to server
server.sin_addr.s_addr = inet_addr("46.105.118.169");
server.sin_family = AF_INET;
server.sin_port = htons( 80 );
if (connect(s , (struct sockaddr *)&server , sizeof(server)) < 0) {
write("log.txt", "server connection - error!");
return false;
}
// send data
string request;
request += "GET /index.php HTTP/1.1\r\n";
request += "Host: machines.host-ed.me\r\n";
request += "Connection: close\r\n";
request += "\r\n";
if (send(s, request.c_str(), request.size(), 0) < 0) {
write("log.txt", "data send - error!");
return false;
}
// receive reply
if ((recv_size = recv(s, server_reply, 4096, 0)) == SOCKET_ERROR) {
write("log.txt", "data receive - error!");
return false;
}
server_reply[recv_size] = '\0';
write("log.txt", string(server_reply)); // gives strange characters
// close socket
closesocket(s);
WSACleanup();
return true;
}
我的意思是奇怪的人物,看看这个回复:
HTTP/1.1 200 OK
Date: Tue, 09 Jan 2018 15:02:01 GMT
Server: Apache
Connection: close
Transfer-Encoding: chunked
Content-Type: text/html
9
hello PHP
0
我指的是内容前后的 9 和 0 。我在服务器中的PHP代码如下所示:
<?php echo "hello PHP"; ?>
我不知道它是否是服务器问题,但如果将文本更改为&#34; hello2 PHP&#34;,则返回我的winsock代码,如下所示:
a
hello2 PHP
我无能为力
答案 0 :(得分:1)
您所看到的是HTTP 1.1 chunked transfer encoding,正如标题中服务器指定的那样
