I'm trying different ways but with no luck.

First of all the code:
Qt Code: 
  1. class InternetJob: public QObject
  2. {
  3. 	Q_OBJECT
  4.  
  5. 	public:
  6. 		InternetJob(const QString &u);
  7. 		QByteArray getData(){return data;}
  8. 		int getStatusCode(){return statusCode;}
  9. 		QString getLocation(){return location;}
  10. 		bool isRequestAborted(){return httpRequestAborted;}
  11. 		bool isRedirecting(){return needRedirect;}
  12. 		void download();
  13.  
  14. 	private slots:
  15. 		void httpRequestFinished(int requestId, bool error);
  16. 		void readResponseHeader(const QHttpResponseHeader &responseHeader);
  17.  
  18. 	signals:
  19. 		void requestFinished();
  20.  
  21. 	private:
  22. 		QHttp *http;
  23. 		QUrl url;
  24. 		bool httpRequestAborted;
  25. 		int httpGetId;
  26. 		QByteArray data;
  27. 		int statusCode;
  28. 		QString location;
  29. };
  30.  
  31. InternetJob::InternetJob(const QString &u)
  32. 	: url(u)
  33. {
  34. 	http = new QHttp;
  35. 	connect(http, SIGNAL(responseHeaderReceived(const QHttpResponseHeader &)), this, SLOT(readResponseHeader(const QHttpResponseHeader &)));
  36. 	connect(http, SIGNAL(requestFinished(int, bool)), this, SLOT(httpRequestFinished(int, bool)));
  37.  
  38. 	download();
  39. }
  40.  
  41. void InternetJob::download()
  42. {
  43. 	QString query;
  44. 	for(int i = 0; i < url.queryItems().size(); ) {
  45. 		query += url.queryItems().at(i).first + "=" + url.queryItems().at(i).second;
  46. 		if(++i < url.queryItems().size())
  47. 			query += "&";
  48. 	}
  49.  
  51. 	if(url.queryItems().size() > 0)
  52. 		header.setRequest("GET", url.path() + "?" + QUrl::toPercentEncoding(query,"&="));
  53. 	else
  54. 		header.setRequest("GET", url.path());
  55. 	header.setValue("Host", url.host());
  56.  
  57. 	httpRequestAborted = false;
  58. 	http->setHost(url.host());
  59. 	httpGetId = http->request(header);
  60. 	qDebug() << "job id = " << httpGetId;
  61. }
  62.  
  63. void InternetJob::readResponseHeader(const QHttpResponseHeader &responseHeader)
  64. {
  65. 	statusCode = responseHeader.statusCode();
  66. 	QRegExp rx("\?$");
  67.  
  68. 	switch(statusCode) {
  69. 		case 200:
  70. 		case 301:
  71. 		case 303:
  72. 		case 307:
  73. 			break;
  74.  
  75. 		case 302:
  76. 			location = responseHeader.value("Location");
  77. 			// Remove trailing "?"
  78. 			location.remove(rx.indexIn(location), 1);
  79. 			httpRequestAborted = true;
  80. 			http->abort();
  81. 			break;
  82.  
  83. 		default:
  84. 			qDebug() << QString(trUtf8("Download failed: %1.").arg(responseHeader.reasonPhrase()));
  85. 			httpRequestAborted = true;
  86. 			http->abort();
  87. 	}
  88. }
  89.  
  90. void InternetJob::httpRequestFinished(int requestId, bool error)
  91. {
  92. 	if (requestId != httpGetId)
  93. 		return;
  94. 	qDebug() << "job finished = " << requestId;
  95. 	if (httpRequestAborted) {
  96. 		qDebug() << "Request Aborted. Status Code: " << statusCode;
  97. 		if(statusCode == 302) {
  98. 			url.setUrl(location);
  99. 			download();
  100. 			return;
  101. 		}
  102. 		else {
  103. 			emit requestFinished();
  104. 			return;
  105. 		}
  106. 	}
  107.  
  108. 	if(error)
  109. 		qDebug() << QString(trUtf8("Download failed: %1.").arg(http->errorString()));
  110. 	else
  111. 		data = http->readAll();
  112. 	emit requestFinished();
  113. }

The code above works well until the http status code is 200; if the status code is 302 it starts a new http->request(...) but after it neither responseHeaderReceived nor httpRequestFinished signals are emitted.

Where is my mistake?

Thanks
