Qt通过Http上传文件（路过）

web端：

 

<?php
 $c = $GLOBALS['HTTP_RAW_POST_DATA'];
 $n = $_GET["filename"];
 $fp = fopen($n,'w+');
 fwrite($fp, $c, strlen($c));
 fclose($fp);
?>

 

QT端：

.h文件:

private:
  QNetworkAccessManager *_uploadManager;
  QNetworkReply *_reply;
  char* m_buf;
private slots:
  void replyFinished( QNetworkReply* );
  void upLoadError(QNetworkReply::NetworkError errorCode);
  void OnUploadProgress( qint64 bytesSent, qint64 bytesTotal );

.cpp文件:

_uploadManager = new QNetworkAccessManager(this);
  connect(_uploadManager,SIGNAL(finished(QNetworkReply*)),SLOT(replyFinished(QNetworkReply*)));
  m_buf = NULL;

  QFile file("d:/a.jpg");
  file.open(QIODevice::ReadOnly);
  int file_len = file.size();
  QDataStream in(&file);
  m_buf = new char[file_len];
  in.readRawData( m_buf, file_len);
  file.close();

  QNetworkRequest request(QUrl(tr(http://localhost/up.php?act=up&filename=a.jpg)));
  request.setHeader(QNetworkRequest::ContentTypeHeader, "application/octet-stream");
  QByteArray arr = QByteArray(m_buf, file_len);
  _reply = _uploadManager->post(request , arr);
  connect(_reply, SIGNAL(error(QNetworkReply::NetworkError)), this, SLOT(upLoadError(QNetworkReply::NetworkError)));
  connect(_reply, SIGNAL(uploadProgress ( qint64 ,qint64 )), this, SLOT( OnUploadProgress(qint64 ,qint64 )));
