Request methods (get, post, put, delete, head, options) all take a common set of options. These are:
body
:
Body of the request. If passed a Hash, will try to normalize it first, by default passing it to ActiveSupport::to_params. Any other kind of object will get used as-is.
http_proxyaddr
:
Address of proxy server to use.
http_proxyport
:
Port of proxy server to use.
limit
:
Maximum number of redirects to follow. Takes precedences over
:no_follow
.
query
:
Query string, or a Hash representing it. Normalized according to the same
rules as :body
. If you specify this on a POST, you must use a
Hash. See also #default_params.
timeout
:
Timeout for opening connection and reading data.
There are also another set of options with names corresponding to various class methods. The methods in question are those that let you set a class-wide default, and the options override the defaults on a request-by-request basis. Those options are:
:base_uri
: see #base_uri.
:basic_auth
: see #basic_auth. Only one of
:basic_auth
and :digest_auth
can be used at a
time; if you try using both, you'll get an ArgumentError.
:debug_output
: see #debug_output.
:digest_auth
: see #digest_auth. Only one of
:basic_auth
and :digest_auth
can be used at a
time; if you try using both, you'll get an ArgumentError.
:format
: see #format.
:headers
: see #headers. Must be a Hash.
:maintain_method_across_redirects
: see #maintain_method_across_redirects.
:no_follow
: see #no_follow.
:parser
: see #parser.
:pem
: see #pem.
:query_string_normalizer
: see #query_string_normalizer
:ssl_ca_file
: see #ssl_ca_file.
Allows setting a base uri to be used for each request. Will normalize uri to include http, etc.
class Foo include HTTParty base_uri 'twitter.com' end
# File lib/httparty.rb, line 84 def base_uri(uri=nil) return default_options[:base_uri] unless uri default_options[:base_uri] = HTTParty.normalize_base_uri(uri) end
Allows setting basic authentication username and password.
class Foo include HTTParty basic_auth 'username', 'password' end
# File lib/httparty.rb, line 95 def basic_auth(u, p) default_options[:basic_auth] = {:username => u, :password => p} end
Set an output stream for debugging, defaults to $stderr. The output stream is passed on to Net::HTTP#set_debug_output.
class Foo include HTTParty debug_output $stderr end
# File lib/httparty.rb, line 163 def debug_output(stream = $stderr) default_options[:debug_output] = stream end
Allows setting default parameters to be appended to each request. Great for api keys and such.
class Foo include HTTParty default_params :api_key => 'secret', :another => 'foo' end
# File lib/httparty.rb, line 138 def default_params(h={}) raise ArgumentError, 'Default params must be a hash' unless h.is_a?(Hash) default_options[:default_params] ||= {} default_options[:default_params].merge!(h) end
Allows setting a default timeout for all HTTP calls Timeout is specified in seconds.
class Foo include HTTParty default_timeout 10 end
# File lib/httparty.rb, line 151 def default_timeout(t) raise ArgumentError, 'Timeout must be an integer or float' unless t && (t.is_a?(Integer) || t.is_a?(Float)) default_options[:timeout] = t end
Perform a DELETE request to a path
# File lib/httparty.rb, line 368 def delete(path, options={}) perform_request Net::HTTP::Delete, path, options end
Allows setting digest authentication username and password.
class Foo include HTTParty digest_auth 'username', 'password' end
# File lib/httparty.rb, line 105 def digest_auth(u, p) default_options[:digest_auth] = {:username => u, :password => p} end
Do not send rails style query strings. Specically, don't use bracket notation when sending an array
For a query:
get '/', :query => {:selected_ids => [1,2,3]}
The default query string looks like this:
/?selected_ids[]=1&selected_ids[]=2&selected_ids[]=3
Call `#disable_rails_query_string_format` to transform the query string into:
/?selected_ids=1&selected_ids=2&selected_ids=3
@example
class Foo include HTTParty disable_rails_query_string_format end
# File lib/httparty.rb, line 127 def disable_rails_query_string_format query_string_normalizer Request::NON_RAILS_QUERY_STRING_NORMALIZER end
Proceed to the location header when an HTTP response dictates a redirect. Redirects are always followed by default.
@example
class Foo include HTTParty base_uri 'http://google.com' follow_redirects true end
# File lib/httparty.rb, line 193 def follow_redirects(value = true) default_options[:follow_redirects] = value end
Allows setting the format with which to parse. Must be one of the allowed formats ie: json, xml
class Foo include HTTParty format :json end
# File lib/httparty.rb, line 204 def format(f = nil) if f.nil? default_options[:format] else parser(Parser) if parser.nil? default_options[:format] = f validate_format end end
Allows making a get request to a url.
class Foo include HTTParty end # Simple get with full url Foo.get('http://foo.com/resource.json') # Simple get with full url and query parameters # ie: http://foo.com/resource.json?limit=10 Foo.get('http://foo.com/resource.json', :query => {:limit => 10})
# File lib/httparty.rb, line 342 def get(path, options={}) perform_request Net::HTTP::Get, path, options end
Perform a HEAD request to a path
# File lib/httparty.rb, line 373 def head(path, options={}) perform_request Net::HTTP::Head, path, options end
Allows setting HTTP headers to be used for each request.
class Foo include HTTParty headers 'Accept' => 'text/html' end
# File lib/httparty.rb, line 173 def headers(h={}) raise ArgumentError, 'Headers must be a hash' unless h.is_a?(Hash) default_options[:headers] ||= {} default_options[:headers].merge!(h) end
Allows setting http proxy information to be used
class Foo include HTTParty http_proxy 'http://foo.com', 80 end
# File lib/httparty.rb, line 72 def http_proxy(addr=nil, port = nil) default_options[:http_proxyaddr] = addr default_options[:http_proxyport] = port end
Declare that you wish to maintain the chosen HTTP method across redirects. The default behavior is to follow redirects via the GET method. If you wish to maintain the original method, you can set this option to true.
@example
class Foo include HTTParty base_uri 'http://google.com' maintain_method_across_redirects true end
# File lib/httparty.rb, line 248 def maintain_method_across_redirects(value = true) default_options[:maintain_method_across_redirects] = value end
Declare whether or not to follow redirects. When true, an {HTTParty::RedirectionTooDeep} error will raise upon encountering a redirect. You can then gain access to the response object via HTTParty::ResponseError#response.
@see HTTParty::ResponseError#response
@example
class Foo include HTTParty base_uri 'http://google.com' no_follow true end begin Foo.get('/') rescue HTTParty::RedirectionTooDeep => e puts e.response.body end
# File lib/httparty.rb, line 233 def no_follow(value = false) default_options[:no_follow] = value end
Perform an OPTIONS request to a path
# File lib/httparty.rb, line 378 def options(path, options={}) perform_request Net::HTTP::Options, path, options end
Allows setting a custom parser for the response.
class Foo include HTTParty parser Proc.new {|data| ...} end
# File lib/httparty.rb, line 321 def parser(custom_parser = nil) if custom_parser.nil? default_options[:parser] else default_options[:parser] = custom_parser validate_format end end
Allows setting a PEM file to be used
class Foo include HTTParty pem File.read('/home/user/my.pem'), "optional password" end
# File lib/httparty.rb, line 258 def pem(pem_contents, password=nil) default_options[:pem] = pem_contents default_options[:pem_password] = password end
Allows making a post request to a url.
class Foo include HTTParty end # Simple post with full url and setting the body Foo.post('http://foo.com/resources', :body => {:bar => 'baz'}) # Simple post with full url using :query option, # which gets set as form data on the request. Foo.post('http://foo.com/resources', :query => {:bar => 'baz'})
# File lib/httparty.rb, line 358 def post(path, options={}) perform_request Net::HTTP::Post, path, options end
Perform a PUT request to a path
# File lib/httparty.rb, line 363 def put(path, options={}) perform_request Net::HTTP::Put, path, options end
Override the way query strings are normalized. Helpful for overriding the default rails normalization of Array queries.
For a query:
get '/', :query => {:selected_ids => [1,2,3]}
The default query string normalizer returns:
/?selected_ids[]=1&selected_ids[]=2&selected_ids[]=3
Let's change it to this:
/?selected_ids=1&selected_ids=2&selected_ids=3
Pass a Proc to the query normalizer which accepts the yielded query.
@example Modifying Array query strings
class ServiceWrapper include HTTParty query_string_normalizer proc { |query| query.map do |key, value| value.map {|v| "#{key}=#{v}"} end.join('&') } end
@param [Proc] normalizer custom query string normalizer. @yield [Hash, String] query string @yieldreturn [Array] an array that will later be joined with '&'
# File lib/httparty.rb, line 291 def query_string_normalizer(normalizer) default_options[:query_string_normalizer] = normalizer end
Allows setting an OpenSSL certificate authority file
class Foo include HTTParty ssl_ca_file '/etc/ssl/certs/ca-certificates.crt' end
# File lib/httparty.rb, line 301 def ssl_ca_file(path) default_options[:ssl_ca_file] = path end
Allows setting an OpenSSL certificate authority path (directory)
class Foo include HTTParty ssl_ca_path '/etc/ssl/certs/' end
# File lib/httparty.rb, line 311 def ssl_ca_path(path) default_options[:ssl_ca_path] = path end
