Detailed Description

interface for HTTP request

Member Function Documentation

send()

attribute void _HTTPRequest::send

(

)

send the response to the request

Here is the caller graph for this function:

throttle()

attribute DOMString body attribute unsigned long _HTTPRequest::throttle	(	unsigned long long	done,
		unsigned long long	total
	)

reply body. It is undefined by default

• if reply is 0, this can be set to a file path to serve. If not set, usual URL resolving of httpout is done
• if reply is not 0, this can be set to a string containing the body. To deliver a binary file or a large file, use the read function

callback function used to throttle the download, can be used even if the request is handled by gpac. It is undefined by default

Parameters

done	amount of bytes already sent in request
total	total amount of bytes in request

Returns

a delay for next send in milliseconds

read()

attribute signed long _HTTPRequest::read

(

ArrayBuffer

buffer

)

callback function used to get data (GET requests). It is undefined by default

Parameters

buffer

array buffer to fill (shared array, do NOT keep)

Returns

the number of bytes read, negative value means no data available yet, 0 means end of file

write()

attribute unsigned long _HTTPRequest::write

(

ArrayBuffer

buffer

)

callback function used to receive data (PUT/POST requests). It is undefined by default

Parameters

buffer

array buffer received. If null, end of stream is reached

Returns

the number of bytes written (informative only)

close()

attribute void _HTTPRequest::close

(

unsigned long

error

)

callback function used to monitor end of session. It is undefined by default

Parameters

error

GPAC error code for the session

Field Documentation

reply

attribute unsigned long _HTTPRequest::reply

HTTP reply code to use. If 0, the request is handled by GPAC as usual. Otherwise, the request is handled by your script if the reply does not indicate an error

method

attribute readonly DOMString _HTTPRequest::method

HTTP method of the request

url

attribute readonly DOMString _HTTPRequest::url

HTTP URL of the request

auth_code

attribute readonly unsigned long _HTTPRequest::auth_code

Authentication reply code - requests are pre-identified using GPAC credentials: a value of 401 indicates no identification, 200 indicates identification OK, 403 indicates failure

headers_in

attribute readonly Array _HTTPRequest::headers_in

HTTP headers of the request, array of _HTTPHeader objects

headers_out

attribute Array _HTTPRequest::headers_out

HTTP headers to set on the response, array of _HTTPHeader objects (initialized as empty)
