如果构建一个httpserver用于文件下载

[zwallow51]

编译过了，但是不知道如何添加被能被下载的指定文件

[188080501]

目前不能自动搜索和匹配文件，需要手动根据传入的数据匹配对应的文件，然后调用replyFile接口返回

你好， 感谢你的回信。传入的数据匹配方式是否有例程可以参考一下。 张伟 ***@***.*** 13801276625 电子名片新出VIP模板啦，快来体验>> 扫一扫, 快速添加名片到手机

可以参考下这个

void onRequestAccepted(const QPointer< JQHttpServer::Session > &session)
{
    if ( session->requestMethod() != "GET" )
    {
        session->replyText( "unsupport request method", 404 );
        return;
    }

    auto relativeFilePath = session->requestUrlPath();
    if ( relativeFilePath.isEmpty() )
    {
        session->replyText( "path is empty", 404 );
        return;
    }

    if ( relativeFilePath.isEmpty() ||
         relativeFilePath.startsWith( "." ) ||
         !relativeFilePath.startsWith( "/" ) ||
         relativeFilePath.contains( ".." ) ||
         relativeFilePath.contains( "\\" ) ||
         ( relativeFilePath.size() > 1000 ) )
    {
        session->replyText( "path error", 404 );
        return;
    }

    QFileInfo fileIfno( QString( "%1%2" ).arg( webPath_, relativeFilePath ) );

    if ( !fileIfno.exists() )
    {
        session->replyText( "file not exists", 404 );
        return;
    }

    if ( fileIfno.suffix().toLower() == "html" )
    {
        QFile file( fileIfno.filePath() );
        file.open( QIODevice::ReadOnly );

        const auto data = file.readAll();

        session->replyBytes( data, "text/html;charset=UTF-8" );
    }
    else if ( QSet< QString >( { "png", "jpg", "jpeg", "ico", "bmp" } ).contains( fileIfno.suffix().toLower() ) )
    {
        session->replyImage( fileIfno.filePath() );
    }
    else
    {
        session->replyFile( fileIfno.filePath() );
    }
}
