An instance of the `Net::HTTP' class represents a connection to an HTTP server. The HTTP protocol is described in RFC 2616. The `Net::HTTP' class supports `HTTP/1.0' and `HTTP/1.1'. `Net::HTTP' is a sub-class of `IO::Socket::INET'. You can mix the methods described below with reading and writing from the socket directly. This is not necessary a good idea, unless you know what you are doing. The following methods are provided (in addition to those of `IO::Socket::INET'): $s = Net::HTTP->new( %options ) The `Net::HTTP' constructor method takes the same options as `IO::Socket::INET''s as well as these: Host: Initial host attribute value KeepAlive: Initial keep_alive attribute value SendTE: Initial send_te attribute_value HTTPVersion: Initial http_version attribute value PeerHTTPVersion: Initial peer_http_version attribute value MaxLineLength: Initial max_line_length attribute value MaxHeaderLines: Initial max_header_lines attribute value The `Host' option is also the default for `IO::Socket::INET''s `PeerAddr'. The `PeerPort' defaults to 80 if not provided. The `Listen' option provided by `IO::Socket::INET''s constructor method is not allowed. If unable to connect to the given HTTP server then the constructor returns `undef' and $@ contains the reason. After a successful connect, a `Net:HTTP' object is returned. $s->host Get/set the default value of the `Host' header to send. The $host must not be set to an empty string (or `undef') for HTTP/1.1. $s->keep_alive Get/set the *keep-alive* value. If this value is TRUE then the request will be sent with headers indicating that the server should try to keep the connection open so that multiple requests can be sent. The actual headers set will depend on the value of the `http_version' and `peer_http_version' attributes. $s->send_te Get/set the a value indicating if the request will be sent with a "TE" header to indicate the transfer encodings that the server can choose to use. The list of encodings announced as accepted by this client depends on availability of the following modules: `Compress::Raw::Zlib' for *deflate*, and `IO::Compress::Gunzip' for *gzip*. $s->http_version Get/set the HTTP version number that this client should announce. This value can only be set to "1.0" or "1.1". The default is "1.1". $s->peer_http_version Get/set the protocol version number of our peer. This value will initially be "1.0", but will be updated by a successful read_response_headers() method call. $s->max_line_length Get/set a limit on the length of response line and response header lines. The default is 8192. A value of 0 means no limit. $s->max_header_length Get/set a limit on the number of header lines that a response can have. The default is 128. A value of 0 means no limit. $s->format_request($method, $uri, %headers, [$content]) Format a request message and return it as a string. If the headers do not include a `Host' header, then a header is inserted with the value of the `host' attribute. Headers like `Connection' and `Keep-Alive' might also be added depending on the status of the `keep_alive' attribute. If $content is given (and it is non-empty), then a `Content-Length' header is automatically added unless it was already present. $s->write_request($method, $uri, %headers, [$content]) Format and send a request message. Arguments are the same as for format_request(). Returns true if successful. $s->format_chunk( $data ) Returns the string to be written for the given chunk of data. $s->write_chunk($data) Will write a new chunk of request entity body data. This method should only be used if the `Transfer-Encoding' header with a value of `chunked' was sent in the request. Note, writing zero-length data is a no-op. Use the write_chunk_eof() method to signal end of entity body data. Returns true if successful. $s->format_chunk_eof( %trailers ) Returns the string to be written for signaling EOF when a `Transfer-Encoding' of `chunked' is used. $s->write_chunk_eof( %trailers ) Will write eof marker for chunked data and optional trailers. Note that trailers should not really be used unless is was signaled with a `Trailer' header. Returns true if successful. ($code, $mess, %headers) = $s->read_response_headers( %opts ) Read response headers from server and return it. The $code is the 3 digit HTTP status code (see HTTP::Status) and $mess is the textual message that came with it. Headers are then returned as key/value pairs. Since key letter casing is not normalized and the same key can even occur multiple times, assigning these values directly to a hash is not wise. Only the $code is returned if this method is called in scalar context. As a side effect this method updates the 'peer_http_version' attribute. Options might be passed in as key/value pairs. There are currently only two options supported; `laxed' and `junk_out'. The `laxed' option will make read_response_headers() more forgiving towards servers that have not learned how to speak HTTP properly. The `laxed' option is a boolean flag, and is enabled by passing in a TRUE value. The `junk_out' option can be used to capture bad header lines when `laxed' is enabled. The value should be an array reference. Bad header lines will be pushed onto the array. The `laxed' option must be specified in order to communicate with pre-HTTP/1.0 servers that don't describe the response outcome or the data they send back with a header block. For these servers peer_http_version is set to "0.9" and this method returns (200, "Assumed OK"). The method will raise an exception (die) if the server does not speak proper HTTP or if the `max_line_length' or `max_header_length' limits are reached. If the `laxed' option is turned on and `max_line_length' and `max_header_length' checks are turned off, then no exception will be raised and this method will always return a response code. $n = $s->read_entity_body($buf, $size); Reads chunks of the entity body content. Basically the same interface as for read() and sysread(), but the buffer offset argument is not supported yet. This method should only be called after a successful read_response_headers() call. The return value will be `undef' on read errors, 0 on EOF, -1 if no data could be returned this time, otherwise the number of bytes assigned to $buf. The $buf is set to "" when the return value is -1. You normally want to retry this call if this function returns either -1 or `undef' with `$!' as EINTR or EAGAIN (see Errno). EINTR can happen if the application catches signals and EAGAIN can happen if you made the socket non-blocking. This method will raise exceptions (die) if the server does not speak proper HTTP. This can only happen when reading chunked data. %headers = $s->get_trailers After read_entity_body() has returned 0 to indicate end of the entity body, you might call this method to pick up any trailers. $s->_rbuf Get/set the read buffer content. The read_response_headers() and read_entity_body() methods use an internal buffer which they will look for data before they actually sysread more from the socket itself. If they read too much, the remaining data will be left in this buffer. $s->_rbuf_length Returns the number of bytes in the read buffer. This should always be the same as: length($s->_rbuf) but might be more efficient. SUBCLASSING The read_response_headers() and read_entity_body() will invoke the sysread() method when they need more data. Subclasses might want to override this method to control how reading takes place. The object itself is a glob. Subclasses should avoid using hash key names prefixed with `http_' and `io_'.

An instance of the C class represents a connection to an HTTP server. The HTTP protocol is described in RFC 2616. The C class supports C and C. C is a sub-class of C. You can mix the methods described below with reading and writing from the socket directly. This is not necessary a good idea, unless you know what you are doing. The following methods are provided (in addition to those of C): =over =item $s = Net::HTTP->new( %options ) The C constructor method takes the same options as C's as well as these: Host: Initial host attribute value KeepAlive: Initial keep_alive attribute value SendTE: Initial send_te attribute_value HTTPVersion: Initial http_version attribute value PeerHTTPVersion: Initial peer_http_version attribute value MaxLineLength: Initial max_line_length attribute value MaxHeaderLines: Initial max_header_lines attribute value The C option is also the default for C's C. The C defaults to 80 if not provided. The C option provided by C's constructor method is not allowed. If unable to connect to the given HTTP server then the constructor returns C and $@ contains the reason. After a successful connect, a C object is returned. =item $s->host Get/set the default value of the C header to send. The $host must not be set to an empty string (or C) for HTTP/1.1. =item $s->keep_alive Get/set the I value. If this value is TRUE then the request will be sent with headers indicating that the server should try to keep the connection open so that multiple requests can be sent. The actual headers set will depend on the value of the C and C attributes. =item $s->send_te Get/set the a value indicating if the request will be sent with a "TE" header to indicate the transfer encodings that the server can choose to use. The list of encodings announced as accepted by this client depends on availability of the following modules: C for I, and C for I. =item $s->http_version Get/set the HTTP version number that this client should announce. This value can only be set to "1.0" or "1.1". The default is "1.1". =item $s->peer_http_version Get/set the protocol version number of our peer. This value will initially be "1.0", but will be updated by a successful read_response_headers() method call. =item $s->max_line_length Get/set a limit on the length of response line and response header lines. The default is 8192. A value of 0 means no limit. =item $s->max_header_length Get/set a limit on the number of header lines that a response can have. The default is 128. A value of 0 means no limit. =item $s->format_request($method, $uri, %headers, [$content]) Format a request message and return it as a string. If the headers do not include a C header, then a header is inserted with the value of the C attribute. Headers like C and C might also be added depending on the status of the C attribute. If $content is given (and it is non-empty), then a C header is automatically added unless it was already present. =item $s->write_request($method, $uri, %headers, [$content]) Format and send a request message. Arguments are the same as for format_request(). Returns true if successful. =item $s->format_chunk( $data ) Returns the string to be written for the given chunk of data. =item $s->write_chunk($data) Will write a new chunk of request entity body data. This method should only be used if the C header with a value of C was sent in the request. Note, writing zero-length data is a no-op. Use the write_chunk_eof() method to signal end of entity body data. Returns true if successful. =item $s->format_chunk_eof( %trailers ) Returns the string to be written for signaling EOF when a C of C is used. =item $s->write_chunk_eof( %trailers ) Will write eof marker for chunked data and optional trailers. Note that trailers should not really be used unless is was signaled with a C header. Returns true if successful. =item ($code, $mess, %headers) = $s->read_response_headers( %opts ) Read response headers from server and return it. The $code is the 3 digit HTTP status code (see L) and $mess is the textual message that came with it. Headers are then returned as key/value pairs. Since key letter casing is not normalized and the same key can even occur multiple times, assigning these values directly to a hash is not wise. Only the $code is returned if this method is called in scalar context. As a side effect this method updates the 'peer_http_version' attribute. Options might be passed in as key/value pairs. There are currently only two options supported; C and C. The C option will make read_response_headers() more forgiving towards servers that have not learned how to speak HTTP properly. The C option is a boolean flag, and is enabled by passing in a TRUE value. The C option can be used to capture bad header lines when C is enabled. The value should be an array reference. Bad header lines will be pushed onto the array. The C option must be specified in order to communicate with pre-HTTP/1.0 servers that don't describe the response outcome or the data they send back with a header block. For these servers peer_http_version is set to "0.9" and this method returns (200, "Assumed OK"). The method will raise an exception (die) if the server does not speak proper HTTP or if the C or C limits are reached. If the C option is turned on and C and C checks are turned off, then no exception will be raised and this method will always return a response code. =item $n = $s->read_entity_body($buf, $size); Reads chunks of the entity body content. Basically the same interface as for read() and sysread(), but the buffer offset argument is not supported yet. This method should only be called after a successful read_response_headers() call. The return value will be C on read errors, 0 on EOF, -1 if no data could be returned this time, otherwise the number of bytes assigned to $buf. The $buf is set to "" when the return value is -1. You normally want to retry this call if this function returns either -1 or C with C<$!> as EINTR or EAGAIN (see L). EINTR can happen if the application catches signals and EAGAIN can happen if you made the socket non-blocking. This method will raise exceptions (die) if the server does not speak proper HTTP. This can only happen when reading chunked data. =item %headers = $s->get_trailers After read_entity_body() has returned 0 to indicate end of the entity body, you might call this method to pick up any trailers. =item $s->_rbuf Get/set the read buffer content. The read_response_headers() and read_entity_body() methods use an internal buffer which they will look for data before they actually sysread more from the socket itself. If they read too much, the remaining data will be left in this buffer. =item $s->_rbuf_length Returns the number of bytes in the read buffer. This should always be the same as: length($s->_rbuf) but might be more efficient. =back =head1 SUBCLASSING The read_response_headers() and read_entity_body() will invoke the sysread() method when they need more data. Subclasses might want to override this method to control how reading takes place. The object itself is a glob. Subclasses should avoid using hash key names prefixed with C and C. =head1 SEE ALSO L, L, L =head1 COPYRIGHT Copyright 2001-2003 Gisle Aas.

The interface is the same as the interface for C, but the constructor method take additional parameters as accepted by L. The C object isa C too, which make it inherit additional methods from that base class. For historical reasons this module also supports using C (from the Crypt-SSLeay distribution) as its SSL driver and base class. This base is automatically selected if available and C isn't. You might also force which implementation to use by setting $Net::HTTPS::SSL_SOCKET_CLASS before loading this module. If not set this variable is initialized from the C environment variable. =head1 ENVIRONMENT You might set the C environment variable to the name of the base SSL implementation (and Net::HTTPS base class) to use. The default is C. Currently the only other supported value is C. =head1 SEE ALSO L, L Net-HTTP-6.06/lib/Net/HTTP/Methods.pm000644 000765 000024 00000036327 12117205277 017251 0ustar00gislestaff000000 000000 package Net::HTTP::Methods; require 5.005; # 4-arg substr use strict; use vars qw($VERSION); $VERSION = "6.06"; my $CRLF = "\015\012"; # "\r\n" is not portable *_bytes = defined(&utf8::downgrade) ?

This make it possible to multiplex multiple Net::HTTP::NB using select without risk blocking. If read_response_headers() did not see enough data to complete the headers an empty list is returned. If read_entity_body() did not see new entity data in its read the value -1 is returned. =head1 SEE ALSO L =head1 COPYRIGHT Copyright 2001 Gisle Aas.
