为此,我正在使用带有 QT4 的 C++。当我尝试发送大型 html 文件(在本例中为 8kb)时,发送和接收的过程运行良好。但是收到的文件在 html 文件的每个字符之间都有空格。这里是一个例子,文件是这样发送的:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN" "http://www.w3.org/TR/REC-html40/strict.dtd">
<html><head><meta name="qrichtext" content="1" /><style type="text/css">
p, li { white-space: pre-wrap; }
</style></head><body style=" font-family:'MS Shell Dlg 2'; font-size:8.25pt; font-weight:400; font-style:normal;">
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">a</p></body></html>
它已收到,如下所示:

我用于发送和接收的代码:
发送代码:qDebug() << "已连接。发送文件到服务器"; QString text = ui->QuestHtmlText->toPlainText();
if(text.length() < 1024)
{
QByteArray block;
QDataStream out(&block, QIODevice::WriteOnly);
out << quint16(0) << QUESTION_HTML;
out << text;
out.device()->seek(0);
out << quint16(block.size() - sizeof(quint16));
qDebug() << "Block size: " << block.size();
socket.write(block);
return;
}
for(int i = 0; i < text.length(); i+=1024)
{
QByteArray block;
QDataStream out(&block, QIODevice::WriteOnly);
out << quint16(0) << QUESTION_HTML;
if((text.length() - i) > 1024)
out << text.mid(i, i+1024);
else
out << text.right(1024 - i);
out.device()->seek(0);
out << quint16(block.size() - sizeof(quint16));
qDebug() << "Block size: " << block.size();
socket.write(block);
}
接收代码:
qDebug() << "Writing File";
QDataStream in(this);
QString temp = "Teste.html", text;
QFile myFile(".//Questions//" + temp);
myFile.open(QIODevice::WriteOnly);
QDataStream out(&myFile);
while(!in.atEnd())
{
in >> text;
out << text;
}
