end class HTTPHeaderSyntaxError < StandardError; end # :startdoc: # \Class \Net::HTTP provides a rich library that implements the client # in a client-server model that uses the \HTTP request-response protocol. # For information about \HTTP, see: # # - {Hypertext Transfer Protocol}[https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol]. # - {Technical overview}[https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol#Technical_overview]. # # == About the Examples # # :include: doc/net-http/examples.rdoc # # == Strategies # # - If you will make only a few GET requests, # consider using {OpenURI}[rdoc-ref:OpenURI]. # - If you will make only a few requests of all kinds, # consider using the various singleton convenience methods in this class. # Each of the following methods automatically starts and finishes # a {session}[rdoc-ref:Net::HTTP@Sessions] that sends a single request: # # # Return string response body. # Net::HTTP.get(hostname, path) # Net::HTTP.get(uri) # # # Write string response body to $stdout. # Net::HTTP.get_print(hostname, path) # Net::HTTP.get_print(uri) # # # Return response as Net::HTTPResponse object. # Net::HTTP.get_response(hostname, path) # Net::HTTP.get_response(uri) # data = '{"title": "foo", "body": "bar", "userId": 1}' # Net::HTTP.post(uri, data) # params = {title: 'foo', body: 'bar', userId: 1} # Net::HTTP.post_form(uri, params) # # - If performance is important, consider using sessions, which lower request overhead. # This {session}[rdoc-ref:Net::HTTP@Sessions] has multiple requests for # {HTTP methods}[https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol#Request_methods] # and {WebDAV methods}[https://en.wikipedia.org/wiki/WebDAV#Implementation]: # # Net::HTTP.start(hostname) do |http| # # Session started automatically before block execution. # http.get(path) # http.head(path) # body = 'Some text' # http.post(path, body) # Can also have a block. # http.put(path, body) # http.delete(path) # http.options(path) # http.trace(path) # http.patch(path, body) # Can also have a block. # http.copy(path) # http.lock(path, body) # http.mkcol(path, body) # http.move(path) # http.propfind(path, body) # http.proppatch(path, body) # http.unlock(path, body) # # Session finished automatically at block exit. # end # # The methods cited above are convenience methods that, via their few arguments, # allow minimal control over the requests. # For greater control, consider using {request objects}[rdoc-ref:Net::HTTPRequest]. # # == URIs # # On the internet, a URI # ({Universal Resource Identifier}[https://en.wikipedia.org/wiki/Uniform_Resource_Identifier]) # is a string that identifies a particular resource. # It consists of some or all of: scheme, hostname, path, query, and fragment; # see {URI syntax}[https://en.wikipedia.org/wiki/Uniform_Resource_Identifier#Syntax]. # # A Ruby {URI::Generic}[rdoc-ref:URI::Generic] object # represents an internet URI. # It provides, among others, methods # +scheme+, +hostname+, +path+, +query+, and +fragment+. # # === Schemes # # An internet \URI has # a {scheme}[https://en.wikipedia.org/wiki/List_of_URI_schemes]. # # The two schemes supported in \Net::HTTP are <tt>'https'</tt> and <tt>'http'</tt>: # # uri.scheme # => "https" # URI('http://example.com').scheme # => "http" # # === Hostnames # # A hostname identifies a server (host) to which requests may be sent: # # hostname = uri.hostname # => "jsonplaceholder.typicode.com" # Net::HTTP.start(hostname) do |http| # # Some HTTP stuff. # end # # === Paths # # A host-specific path identifies a resource on the host: # # _uri = uri.dup # _uri.path = '/todos/1' # hostname = _uri.hostname # path = _uri.path # Net::HTTP.get(hostname, path) # # === Queries # # A host-specific query adds name/value pairs to the URI: # # _uri = uri.dup # params = {userId: 1, completed: false} # _uri.query = URI.encode_www_form(params) # _uri # => #<URI::HTTPS https://jsonplaceholder.typicode.com?userId=1&completed=false> # Net::HTTP.get(_uri) # # === Fragments # # A {URI fragment}[https://en.wikipedia.org/wiki/URI_fragment] has no effect # in \Net::HTTP; # the same data is returned, regardless of whether a fragment is included. # # == Request Headers # # Request headers may be used to pass additional information to the host, # similar to arguments passed in a method call; # each header is a name/value pair. # # Each of the \Net::HTTP methods that sends a request to the host # has optional argument +headers+, # where the headers are expressed as a hash of field-name/value pairs: # # headers = {Accept: 'application/json', Connection: 'Keep-Alive'} # Net::HTTP.get(uri, headers) # # See lists of both standard request fields and common request fields at # {Request Fields}[https://en.wikipedia.org/wiki/List_of_HTTP_header_fields#Request_fields]. # A host may also accept other custom fields. # # == \HTTP Sessions # # A _session_ is a connection between a server (host) and a client that: # # - Is begun by instance method Net::HTTP#start. # - May contain any number of requests. # - Is ended by instance method Net::HTTP#finish. # # See example sessions at {Strategies}[rdoc-ref:Net::HTTP@Strategies]. # # === Session Using \Net::HTTP.start # # If you have many requests to make to a single host (and port), # consider using singleton method Net::HTTP.start with a block; # the method handles the session automatically by: # # - Calling #start before block execution. # - Executing the block. # - Calling #finish after block execution. # # In the block, you can use these instance methods, # each of which that sends a single request: # # - {HTTP methods}[https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol#Request_methods]: # # - #get, #request_get: GET. # - #head, #request_head: HEAD. # - #post, #request_post: POST. # - #delete: DELETE. # - #options: OPTIONS. # - #trace: TRACE. # - #patch: PATCH. # # - {WebDAV methods}[https://en.wikipedia.org/wiki/WebDAV#Implementation]: # # - #copy: COPY. # - #lock: LOCK. # - #mkcol: MKCOL. # - #move: MOVE. # - #propfind: PROPFIND. # - #proppatch: PROPPATCH. # - #unlock: UNLOCK. # # === Session Using \Net::HTTP.start and \Net::HTTP.finish # # You can manage a session manually using methods #start and #finish: # # http = Net::HTTP.new(hostname) # http.start # http.get('/todos/1') # http.get('/todos/2') # http.delete('/posts/1') # http.finish # Needed to free resources. # # === Single-Request Session # # Certain convenience methods automatically handle a session by: # # - Creating an \HTTP object # - Starting a session. # - Sending a single request. # - Finishing the session. # - Destroying the object. # # Such methods that send GET requests: # # - ::get: Returns the string response body. # - ::get_print: Writes the string response body to $stdout. # - ::get_response: Returns a Net::HTTPResponse object. # # Such methods that send POST requests: # # - ::post: Posts data to the host. # - ::post_form: Posts form data to the host. # # == \HTTP Requests and Responses # # Many of the methods above are convenience methods, # each of which sends a request and returns a string # without directly using \Net::HTTPRequest and \Net::HTTPResponse objects. # # You can, however, directly create a request object, send the request, # and retrieve the response object; see: # # - Net::HTTPRequest. # - Net::HTTPResponse. # # == Following Redirection # # Each returned response is an instance of a subclass of Net::HTTPResponse. # See the {response class hierarchy}[rdoc-ref:Net::HTTPResponse@Response+Subclasses]. # # In particular, class Net::HTTPRedirection is the parent # of all redirection classes. # This allows you to craft a case statement to handle redirections properly: # # def fetch(uri, limit = 10) # # You should choose a better exception. # raise ArgumentError, 'Too many HTTP redirects' if limit == 0 # # res = Net::HTTP.get_response(URI(uri)) # case res # when Net::HTTPSuccess # Any success class. # res # when Net::HTTPRedirection # Any redirection class. # location = res['Location'] # warn "Redirected to #{location}" # fetch(location, limit - 1) # else # Any other class. # res.value # end # end # # fetch(uri) # # == Basic Authentication # # Basic authentication is performed according to # {RFC2617}[http://www.ietf.org/rfc/rfc2617.txt]: # # req = Net::HTTP::Get.new(uri) # req.basic_auth('user', 'pass') # res = Net::HTTP.start(hostname) do |http| # http.request(req) # end # # == Streaming Response Bodies # # By default \Net::HTTP reads an entire response into memory. If you are # handling large files or wish to implement a progress bar you can instead # stream the body directly to an IO. # # Net::HTTP.start(hostname) do |http| # req = Net::HTTP::Get.new(uri) # http.request(req) do |res| # open('t.tmp', 'w') do |f| # res.read_body do |chunk| # f.write chunk # end # end # end # end # # == HTTPS # # HTTPS is enabled for an \HTTP connection by Net::HTTP#use_ssl=: # # Net::HTTP.start(hostname, :use_ssl => true) do |http| # req = Net::HTTP::Get.new(uri) # res = http.request(req) # end # # Or if you simply want to make a GET request, you may pass in a URI # object that has an \HTTPS URL. \Net::HTTP automatically turns on TLS # verification if the URI object has a 'https' URI scheme: # # uri # => #<URI::HTTPS https://jsonplaceholder.typicode.com/> # Net::HTTP.get(uri) # # == Proxy Server # # An \HTTP object can have # a {proxy server}[https://en.wikipedia.org/wiki/Proxy_server]. # # You can create an \HTTP object with a proxy server # using method Net::HTTP.new or method Net::HTTP.start. # # The proxy may be defined either by argument +p_addr+ # or by environment variable <tt>'http_proxy'</tt>. # # === Proxy Using Argument +p_addr+ as a \String # # When argument +p_addr+ is a string hostname, # the returned +http+ has the given host as its proxy: # # http = Net::HTTP.new(hostname, nil, 'proxy.example') # http.proxy? # => true # http.proxy_from_env? # => false # http.proxy_address # => "proxy.example" # # These use default values. # http.proxy_port # => 80 # http.proxy_user # => nil # http.proxy_pass # => nil # # The port, username, and password for the proxy may also be given: # # http = Net::HTTP.new(hostname, nil, 'proxy.example', 8000, 'pname', 'ppass') # # => #<Net::HTTP jsonplaceholder.typicode.com:80 open=false> # http.proxy? # => true # http.proxy_from_env? # => false # http.proxy_address # => "proxy.example" # http.proxy_port # => 8000 # http.proxy_user # => "pname" # http.proxy_pass # => "ppass" # # === Proxy Using '<tt>ENV['http_proxy']</tt>' # # When environment variable <tt>'http_proxy'</tt> # is set to a \URI string, # the returned +http+ will have the server at that URI as its proxy; # note that the \URI string must have a protocol # such as <tt>'http'</tt> or <tt>'https'</tt>: # # ENV['http_proxy'] = 'http://example.com' # http = Net::HTTP.new(hostname) # http.proxy? # => true # http.proxy_from_env? # => true # http.proxy_address # => "example.com" # # These use default values. # http.proxy_port # => 80 # http.proxy_user # => nil # http.proxy_pass # => nil # # The \URI string may include proxy username, password, and port number: # # ENV['http_proxy'] = 'http://pname:ppass@example.com:8000' # http = Net::HTTP.new(hostname) # http.proxy? # => true # http.proxy_from_env? # => true # http.proxy_address # => "example.com" # http.proxy_port # => 8000 # http.proxy_user # => "pname" # http.proxy_pass # => "ppass" # # === Filtering Proxies # # With method Net::HTTP.new (but not Net::HTTP.start), # you can use argument +p_no_proxy+ to filter proxies: # # - Reject a certain address: # # http = Net::HTTP.new('example.com', nil, 'proxy.example', 8000, 'pname', 'ppass', 'proxy.example') # http.proxy_address # => nil # # - Reject certain domains or subdomains: # # http = Net::HTTP.new('example.com', nil, 'my.proxy.example', 8000, 'pname', 'ppass', 'proxy.example') # http.proxy_address # => nil # # - Reject certain addresses and port combinations: # # http = Net::HTTP.new('example.com', nil, 'proxy.example', 8000, 'pname', 'ppass', 'proxy.example:1234') # http.proxy_address # => "proxy.example" # # http = Net::HTTP.new('example.com', nil, 'proxy.example', 8000, 'pname', 'ppass', 'proxy.example:8000') # http.proxy_address # => nil # # - Reject a list of the types above delimited using a comma: # # http = Net::HTTP.new('example.com', nil, 'proxy.example', 8000, 'pname', 'ppass', 'my.proxy,proxy.example:8000') # http.proxy_address # => nil # # http = Net::HTTP.new('example.com', nil, 'my.proxy', 8000, 'pname', 'ppass', 'my.proxy,proxy.example:8000') # http.proxy_address # => nil # # == Compression and Decompression # # \Net::HTTP does not compress the body of a request before sending. # # By default, \Net::HTTP adds header <tt>'Accept-Encoding'</tt> # to a new {request object}[rdoc-ref:Net::HTTPRequest]: # # Net::HTTP::Get.new(uri)['Accept-Encoding'] # # => "gzip;q=1.0,deflate;q=0.6,identity;q=0.3" # # This requests the server to zip-encode the response body if there is one; # the server is not required to do so. # # \Net::HTTP does not automatically decompress a response body # if the response has header <tt>'Content-Range'</tt>. # # Otherwise decompression (or not) depends on the value of header # {Content-Encoding}[https://en.wikipedia.org/wiki/List_of_HTTP_header_fields#content-encoding-response-header]: # # - <tt>'deflate'</tt>, <tt>'gzip'</tt>, or <tt>'x-gzip'</tt>: # decompresses the body and deletes the header. # - <tt>'none'</tt> or <tt>'identity'</tt>: # does not decompress the body, but deletes the header. # - Any other value: # leaves the body and header unchanged. # # == What's Here # # This is a categorized summary of methods and attributes. #
