Object
This class represents multiple request/response transactions with an HTTP server. This is the primary API for Patron.
Maximum number of times to follow redirects. Set to 0 to disable and -1 to follow all redirects. Defaults to 5.
Set the buffer size for this request. This option will only be set if buffer_size is non-nil
Create a new Session object.

Sends a WebDAV COPY request to the specified url.
# File lib/patron/session.rb, line 181 181: def copy(url, dest, headers = {}) 182: headers['Destination'] = dest 183: request(:copy, url, headers) 184: end
As # but sends an HTTP DELETE request.
# File lib/patron/session.rb, line 141 141: def delete(url, headers = {}) 142: request(:delete, url, headers) 143: end
Enable debug output to stderr or to specified file.

URL escapes the provided string.

Retrieve the contents of the specified url optionally sending the specified headers. If the base_url varaible is set then it is prepended to the url parameter. Any custom headers are merged with the contents of the headers instance variable. The results are returned in a Response object. Notice: this method doesn’t accept any data argument: if you need to send data with a get request, please, use the # method.
# File lib/patron/session.rb, line 125 125: def get(url, headers = {}) 126: request(:get, url, headers) 127: end
Retrieve the contents of the specified url as with #, but the content at the URL is downloaded directly into the specified file.
# File lib/patron/session.rb, line 131 131: def get_file(url, filename, headers = {}) 132: request(:get, url, headers, :file => filename) 133: end
Peform the actual HTTP request by calling libcurl. Each filed in the request object will be used to set the appropriate option on the libcurl library. After the request completes, a Response object will be created and returned.
In the event of an error in the libcurl library, a Ruby exception will be created and raised. The exception will return the libcurl error code and error message.
static VALUE session_handle_request(VALUE self, VALUE request)
As # but sends an HTTP HEAD request.
# File lib/patron/session.rb, line 136 136: def head(url, headers = {}) 137: request(:head, url, headers) 138: end
Interrupt any currently executing request. This will cause the current request to error and raise an exception.
static VALUE session_interrupt(VALUE self)

static VALUE set_debug_file(VALUE self, VALUE file)
Unescapes the provided string.
static VALUE session_unescape(VALUE self, VALUE value)
