Detailed Description

Some changes have been made to the library to fit it better into Stellarium. The main differences are:

The settings are no longer specified using QSettings, but with configuration structs (HttpListenerSettings, StaticFileControllerSettings, etc)
The template engine supports translating strings at runtime through tags in pseudo-PHP style instead of just different files per language (ITemplateTranslationProvider, Template::translate)
The Content-Type detection of the StaticFileController has been extended to use QMimeDatabase, if required.

◆ HttpConnectionHandlerSettings

struct HttpConnectionHandlerSettings

Contains all settings for the connection handler

Data Fields
int	readTimeout
	Defines the maximum time to wait for a complete HTTP request in msec. More...

int	maxRequestSize
	Maximum size of a request in bytes. More...

int	maxMultipartSize
	Maximum size of a multipart request in bytes. More...

Field Documentation

◆ maxMultipartSize

int HttpConnectionHandlerSettings::maxMultipartSize

Default 1048576 (1MB)

◆ maxRequestSize

int HttpConnectionHandlerSettings::maxRequestSize

Default 16384.

◆ readTimeout

int HttpConnectionHandlerSettings::readTimeout

Default 10000.

◆ HttpConnectionHandler

class HttpConnectionHandler

The connection handler accepts incoming connections and dispatches incoming requests to to a request mapper. Since HTTP clients can send multiple requests before waiting for the response, the incoming requests are queued and processed one after the other.

Example for the required configuration settings:

readTimeout=60000
maxRequestSize=16000
maxMultiPartSize=1000000

The readTimeout value defines the maximum time to wait for a complete HTTP request.

See also: HttpRequest for description of config settings maxRequestSize and maxMultiPartSize.

Data Fields

	The minimal number of threads kept in the pool at all times. More...

int	maxThreads
	The maximal number of threads. More...

int	cleanupInterval
	The time after which inactive threads are stopped in msec. More...

Field Documentation

◆ cleanupInterval

int HttpConnectionHandlerPoolSettings::cleanupInterval

Default 1000.

◆ maxThreads

int HttpConnectionHandlerPoolSettings::maxThreads

If a new connection arrives when this amount of threads is already busy, the new connection will be dropped. Default 100.

◆ minThreads

int HttpConnectionHandlerPoolSettings::minThreads

Default 1.

◆ sslCertFile

QString HttpConnectionHandlerPoolSettings::sslCertFile

Default empty.

◆ sslKeyFile

QString HttpConnectionHandlerPoolSettings::sslKeyFile

Default empty.

◆ HttpConnectionHandlerPool

class HttpConnectionHandlerPool

Pool of http connection handlers. The size of the pool grows and shrinks on demand.

Example for the required configuration settings:

minThreads=4
maxThreads=100
cleanupInterval=60000
readTimeout=60000
;sslKeyFile=ssl/my.key
;sslCertFile=ssl/my.cert
maxRequestSize=16000
maxMultiPartSize=1000000

After server start, the size of the thread pool is always 0. Threads are started on demand when requests come in. The cleanup timer reduces the number of idle threads slowly by closing one thread in each interval. But the configured minimum number of threads are kept running.

For SSL support, you need an OpenSSL certificate file and a key file. Both can be created with the command

    openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout my.key -out my.cert

Visit http://slproweb.com/products/Win32OpenSSL.html to download the Light version of OpenSSL for Windows.

Please note that a listener with SSL settings can only handle HTTPS protocol. To support both HTTP and HTTPS simultaneously, you need to start two listeners on different ports - one with SLL and one without SSL.

◆ HttpListener

class HttpListener

Listens for incoming TCP connections and and passes all incoming HTTP requests to your implementation of HttpRequestHandler, which processes the request and generates the response (usually a HTML document).

Example for the required settings in the config file:

;host=192.168.0.100
port=8080
minThreads=1
maxThreads=10

◆ HttpRequestHandler

class HttpRequestHandler

The request handler generates a response for each HTTP request. Web Applications usually have one central request handler that maps incoming requests to several controllers (servlets) based on the requested path.

You need to override the service() method or you will always get an HTTP error 501.

Warning: Be aware that the main request handler instance must be created on the heap and that it is used by multiple threads simultaneously.

See also: StaticFileController which delivers static local files.

class HttpResponse

This object represents a HTTP response, used to return something to the web client.

  response.setStatus(200,"OK"); // optional, because this is the default
  response.writeBody("Hello");

Example how to return an error:

  response.setStatus(500,"server error");
  response.write("The request cannot be processed because the servers is broken",true);

In case of large responses (e.g. file downloads), a Content-Length header should be set before calling write(). Web Browsers use that information to display a progress bar.

This might be useful to cancel the generation of large or slow responses.

◆ redirect()

void HttpResponse::redirect ( const QByteArray & url )

Cannot be combined with write().

Parameters

url	Destination URL

◆ setCookie()

void HttpResponse::setCookie ( const HttpCookie & cookie )

You must call this method before the first write().

◆ setHeader() [1/2]

name	name of the header
value	value of the header

◆ setStatus()

void HttpResponse::write	(	QByteArray	data,
		bool	lastPart = `false`

Chunked mode is automatically selected if there is no Content-Length header and also no Connection:close header.

Parameters

data	Data bytes of the body
lastPart	Indicates that this is the last chunk of data and flushes the output buffer.

Field Documentation

◆ cacheSize

◆ cacheTime

int StaticFileControllerSettings::cacheTime

Default 60000.

◆ encoding

QString StaticFileControllerSettings::encoding

Default UTF-8

◆ maxAge

int StaticFileControllerSettings::maxAge

Default 60.

◆ maxCachedFileSize

int StaticFileControllerSettings::maxCachedFileSize

Default 65536 (64KB)

◆ path

QString StaticFileControllerSettings::path

Default empty (= current working directory).

◆ StaticFileController

class StaticFileController

Delivers static files. It is usually called by the applications main request handler when the caller requests a path that is mapped to static files.

The following settings are required in the config file:

path=../docroot
encoding=UTF-8
maxAge=60000
cacheTime=60000
cacheSize=1000000
maxCachedFileSize=65536

The path is relative to the directory of the config file. In case of windows, if the settings are in the registry, the path is relative to the current working directory.

The encoding is sent to the web browser in case of text and html files.

The cache improves performance of small files when loaded from a network drive. Large files are not cached. Files are cached as long as possible, when cacheTime=0. The maxAge value (in msec!) controls the remote browsers cache.

Do not instantiate this class in each request, because this would make the file cache useless. Better create one instance during start-up and call it when the application received a related HTTP request.
