sets the TCP_NODELAY flag on the object

This function will try to set the TCP_NODELAY flag immediately if the socket is connected, otherwise will it set a flag and the TCP_NODELAY option will be set on the next connection. If an error occurs setting TCP_NODELAY on a connected socket, then this function will return a non-zero value, and errno will be set

set options with a hash, returns -1 if an exception was thrown, 0 for OK

options are:

protocols: a hash where each key is a protocol name and the value must be set to a integer giving a port number or a hash having the following keys:
port: giving the port number
ssl: giving a boolean true or false value
max_redirects: sets the max_redirects option
default_port: sets the default port number
proxy: sets the proxy URL
url: sets the default connection URL
default_path: sets the default path
timeout: sets the connection or response packet timeout value in milliseconds
http_version: either "1.0" or "1.1" to set the default HTTP version to use
connect_timeout: an integer giving the timeout value for new socket connections in milliseconds
Note
this function is unlocked and designed only to be called with the constructor

Parameters

opts the options to set for the object

xsink if an error occurs, the Qore-language exception information will be added here

Returns
-1 if an exception was thrown, 0 for OK

◆ setProxyURL()

DLLEXPORT int QoreHttpClientObject::setProxyURL	(	const char *	proxy,

Parameters

user	the username to set
pass	the password to set

Note: setURL() will overwrite any settings set here

The documentation for this class was generated from the following file:

/Users/david/src/qore/git/qore/include/qore/QoreHttpClientObject.h
