Overview
It is useful to re-use a HTTPClient instance for multiple requests, to re-use HTTP 1.1 persistent connections.
To do that, you sometimes want to store an HTTPClient instance in a global/ class variable location, so it can be accessed and re-used.
This mix-in makes it easy to create class-level access to one or more HTTPClient instances. The HTTPClient instances are lazily initialized on first use (to, for instance, avoid interfering with WebMock/VCR), and are initialized in a thread-safe manner. Note that a HTTPClient, once initialized, is safe for use in multiple threads.
Note that you ‘extend` HTTPClient::IncludeClient, not `include.
require 'httpclient/include_client'
class Widget
extend HTTPClient::IncludeClient
include_http_client
# and/or, specify more stuff
include_http_client('http://myproxy:8080', :method_name => :my_client) do |client|
# any init you want
client.set_cookie_store nil
client.
end
end
That creates two HTTPClient instances available at the class level. The first will be available from Widget.http_client (default method name for ‘include_http_client`), with default initialization.
The second will be available at Widget.my_client, with the init arguments provided, further initialized by the block provided.
In addition to a class-level method, for convenience instance-level methods are also provided. Widget.http_client is identical to Widget.new.http_client

#get_content(uri, *args, &block) ⇒ Object
Retrieves a web resource.
- uri
-
a String or an URI object which represents an URL of web resource.
- query
-
a Hash or an Array of query part of URL. e.g. { “a” => “b” } => ‘host/part?a=b’. Give an array to pass multiple value like
- [“a”, “b”], [“a”, “c”]
-
> ‘host/part?a=b&a=c’.
- header
-
a Hash or an Array of extra headers. e.g. { ‘Accept’ => ‘text/html’ } or [[‘Accept’, ‘image/jpeg’], [‘Accept’, ‘image/png’]].
- &block
-
Give a block to get chunked message-body of response like get_content(uri) { |chunked_body| … }. Size of each chunk may not be the same.
get_content follows HTTP redirect status (see HTTP::Status.redirect?) internally and try to retrieve content from redirected URL. See redirect_uri_callback= how HTTP redirection is handled.
If you need to get full HTTP response including HTTP status and headers, use get method. get returns HTTP::Message as a response and you need to follow HTTP redirect by yourself if you need.

#no_proxy ⇒ Object
Returns NO_PROXY setting String if given.
467 468 469 |
# File 'lib/httpclient.rb', line 467 def no_proxy @no_proxy end |
#no_proxy=(no_proxy) ⇒ Object
Sets NO_PROXY setting String. no_proxy must be a comma separated String. Each entry must be ‘host’ or ‘host:port’ such as; HTTPClient#no_proxy = ‘example.com,example.co.jp:443’
‘localhost’ is treated as a no_proxy site regardless of explicitly listed. HTTPClient checks given URI objects before accessing it. ‘host’ is tail string match. No IP-addr conversion.
You can use environment variable ‘no_proxy’ or ‘NO_PROXY’ for it.
Calling this method resets all existing sessions.

683 684 685 |

#post_content(uri, *args, &block) ⇒ Object
Posts a content.
- uri
-
a String or an URI object which represents an URL of web resource.
- body
-
a Hash or an Array of body part. e.g.
{ "a" => "b" } => 'a=b'
Give an array to pass multiple value like
[["a", "b"], ["a", "c"]] => 'a=b&a=c'
When you pass a File as a value, it will be posted as a multipart/form-data. e.g.
{ 'upload' => file }
You can also send custom multipart by passing an array of hashes. Each part must have a :content attribute which can be a file, all other keys will become headers.
[{ 'Content-Type' => 'text/plain', :content => "some text" }, { 'Content-Type' => 'video/mp4', :content => File.new('video.mp4') }] => <Two parts with custom Content-Type header>
- header
-
a Hash or an Array of extra headers. e.g.
{ 'Accept' => 'text/html' }
or
[['Accept', 'image/jpeg'], ['Accept', 'image/png']].
- &block
-
Give a block to get chunked message-body of response like
post_content(uri) { |chunked_body| ... }.
Size of each chunk may not be the same.
post_content follows HTTP redirect status (see HTTP::Status.redirect?) internally and try to post the content to redirected URL. See redirect_uri_callback= how HTTP redirection is handled. Bear in mind that you should not depend on post_content because it sends the same POST method to the new location which is prohibited in HTTP spec.
If you need to get full HTTP response including HTTP status and headers, use post method.

#proxy ⇒ Object
Returns URI object of HTTP proxy if exists.
432 433 434 |
# File 'lib/httpclient.rb', line 432 def proxy @proxy end |
#proxy=(proxy) ⇒ Object
Sets HTTP proxy used for HTTP connection. Given proxy can be an URI, a String or nil. You can set user/password for proxy authentication like HTTPClient#proxy = ‘user:passwd@myproxy:8080’
You can use environment variable ‘http_proxy’ or ‘HTTP_PROXY’ for it. You need to use ‘cgi_http_proxy’ or ‘CGI_HTTP_PROXY’ instead if you run HTTPClient from CGI environment from security reason. (HTTPClient checks ‘REQUEST_METHOD’ environment variable whether it’s CGI or not)
Calling this method resets all existing sessions.

Sets callback proc when HTTP redirect status is returned for get_content and post_content. default_redirect_uri_callback is used by default.
If you need strict implementation which does not allow relative URI redirection, set strict_redirect_uri_callback instead.

- &block
-
Give a block to get chunked message-body of response like get(uri) { |chunked_body| … }. Size of each chunk may not be the same.
You can also pass a String as a body. HTTPClient just sends a String as a HTTP request message body.
When you pass an IO as a body, HTTPClient sends it as a HTTP request with chunked encoding (Transfer-Encoding: chunked in HTTP header) if IO does not respond to :read. Bear in mind that some server application does not support chunked request. At least cgi.rb does not support it.

#request_async(method, uri, query = nil, body = nil, header = {}) ⇒ Object
Sends a request in async style. request method creates new Thread for HTTP connection and returns a HTTPClient::Connection instance immediately.
Arguments definition is the same as request.

#reset(uri) ⇒ Object
Resets internal session for the given URL. Keep-alive connection for the site (host-port pair) is disconnected if exists.

# File 'lib/httpclient.rb', line 852 def reset(uri) uri = urify(uri) @session_manager.reset(uri) end |
#reset_all ⇒ Object
Resets all of internal sessions. Keep-alive connections are disconnected.

#save_cookie_store ⇒ Object
Try to save Cookies to the file specified in set_cookie_store. Unexpected error will be raised if you don’t call set_cookie_store first. (interface mismatch between WebAgent::CookieManager implementation)

#set_auth(domain, user, passwd) ⇒ Object
Sets credential for Web server authentication.
- domain
-
a String or an URI to specify where HTTPClient should use this
credential. If you set uri to nil, HTTPClient uses this credential
wherever a server requires it.
- user
-
username String.
- passwd
-
password String.
You can set multiple credentials for each uri.
clnt.set_auth('http://www.example.com/foo/', 'foo_user', 'passwd')
clnt.set_auth('http://www.example.com/bar/', 'bar_user', 'passwd')
Calling this method resets all existing sessions.

#set_cookie_store(filename) ⇒ Object
Sets the filename where non-volatile Cookies be saved by calling save_cookie_store. This method tries to load and managing Cookies from the specified file.
Calling this method resets all existing sessions.

#set_proxy_auth(user, passwd) ⇒ Object
Sets credential for Proxy authentication.
- user
-
username String.
- passwd
-
password String.
Calling this method resets all existing sessions.

#strict_redirect_uri_callback(uri, res) ⇒ Object
A method for redirect uri callback. How to use:
clnt.redirect_uri_callback = clnt.method(:strict_redirect_uri_callback)
This callback does not allow relative redirect such as
Location: ../foo/
in HTTP header. (raises BadResponseError instead)

Sends TRACE request to the specified URL. See request for arguments.
