我有C++服务器与boost.asio和php客户端写。当我发送少量数据时,我得到了所有的数据,但是当我发送长串时,我大部分都是松散的。发送和接收的数据是不一样的大小
这里是我从我的服务器发送数据的部分,它说我已经送出了65536个字节
void handle_write(const boost::system::error_code& /*error*/,
size_t size/*bytes_transferred*/) {
cout <<size<<endl;
}
void handler_read(const boost::system::error_code&, std::size_t size) {
istream is(&buffer);
string myString;
getline(is, myString);
Manager myManager(myString);
string response = myManager.getResponse();
boost::asio::async_write(socket_,
boost::asio::buffer(response),
boost::bind(&tcp_connection::handle_write, shared_from_this(),
boost::asio::placeholders::error,
boost::asio::placeholders::bytes_transferred));
}
在这里,我使字符串我将派出
string getMap(string name, string pass) {
if (name == "admin" && pass == "123") {
string response = "";
ConvertTypes types;
response = types.intToString(MAP_HEIGHT) + " ";
response += types.intToString(MAP_WIDTH) + "\r\n";
for (int i=0; i<MAP_HEIGHT;i++) {
for (int j=0;j<MAP_WIDTH;j++) {
response += types.intToString(
worldMap[i][j].getHeight()) + " ";
response += types.intToString(
worldMap[i][j].getIsTown()) + " ";
response += string (1, worldMap[i][j].getTetrain())
+"\r\n";
}
}
return response;
} else {
return "";
}
}
在PHP端我读取发送的数据,stream_get_meta_data说我只收到8183字节的数据。
print_r($this->socket->getStatus());
for ($i=0; $i<$MAP_HEIGHT;$i++) {
for ($j=0; $j<$MAP_WIDTH;$j++) {
$this->response = $this->socket->readLine();
$this->response = explode(' ', $this->response);
echo "<p>";
echo "$i $j <br>";
print_r($this->response);
echo '<br>';
print_r($keyArray);
$map[$i][$j] = array_combine($keyArray, $this->response);
$this->response = $this->socket->readLine();
} }
}
我不知道PHP,但是不能保证网络数据包将全部在一个块中传递,如果您稍等一会然后再次尝试读取,是否还有更多信息可用? – forsvarir 2011-03-17 15:45:03
