Detailed Description

class for HTTP connections; returns Qore::HTTPClient objects

Supports the following options:

"assume_encoding": assumes the given encoding if the server does not send a charset value
"connect_timeout": connection timeout to use in milliseconds (default: 45 seconds)
"error_passthru": if True then HTTP status codes indicating errors will not cause an HTTP-CLIENT-RECEIVE-ERROR exception to be raised, rather such responses will be passed through to the caller like any other response
"http_version": HTTP version to use ("1.0" or "1.1", defaults to "1.1")
"max_redirects": maximum redirects to support
"pre_encoded_urls": If True then all URI paths in URLs are assumed to be already percent encoded; if this flag is set and any unencoded characters are sent in a URL with a new request, an exception is raised
"proxy": proxy URL to use
"redirect_passthru": if True then redirect responses will be passed to the caller instead of processed
"ssl_cert_path": a path to an X.509 client certificate file in PEM format
"ssl_key_path": a path to a private key file in PEM format for the X.509 client certificate
"ssl_key_password": the password to the private key given with "ssl_key_path"
"ssl_verify_cert": if True then the server's certificate will only be accepted if it's verified
"timeout": transfer timeout to use in milliseconds (default: 45 seconds)

See also: HTTPClient::constructor(hash<auto> opts) for more information on the above options

Member Function Documentation

◆ constructor()

ConnectionProvider::HttpConnection::constructor	(	string	name,
		string	desc,
		string	url,
		hash< auto >	attributes = `{}`,
		hash< auto >	options = `{}`
	)

Creates the HttpConnection object.

Parameters

name	the name of the connection
desc	connection description
url	connection URL (potentially with password info)
attributes	various attributes. See below
options	connection options

See AbstractConnection::constructor() for attributes and options reference.

Exceptions

CONNECTION-OPTION-ERROR missing or invalid connection option

◆ getDataProvider()

DataProvider::AbstractDataProvider ConnectionProvider::HttpConnection::getDataProvider ( )

Returns an HttpDataProvider object for this connection.

Returns: an HttpDataProvider object for this connection

See also: hasDataProvider()

◆ getImpl()

Qore::HTTPClient ConnectionProvider::HttpConnection::getImpl	(	bool	connect = `True`,
		*hash< auto >	rtopts
	)

privatevirtual

returns an Qore::HTTPClient object

Parameters

connect	if True then a connection is made by calling Qore::HTTPClient::connect() before returning the object
rtopts	this connection type does not accept any runtime option, so this parameter is ignored

Implements ConnectionProvider::AbstractConnection.
