Strategies

  • If you will make only a few GET requests, consider using 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 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)
    data = '{"title": "foo", "body": "bar", "userId": 1}'
    Net::HTTP.put(uri, data)
    
  • If performance is important, consider using sessions, which lower request overhead. This session has multiple requests for HTTP methods and WebDAV methods:

    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.

URIs

On the internet, a URI (Universal 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.

A Ruby 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.

The two schemes supported in Net::HTTP are 'https' and 'http':

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 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. 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.

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:

    • #get, #request_get: GET.

    • #head, #request_head: HEAD.

    • #post, #request_post: POST.

    • #delete: DELETE.

    • #options: OPTIONS.

    • #trace: TRACE.

    • #patch: PATCH.

  • WebDAV methods:

    • #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.

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:

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.

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 'http_proxy'.

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 ‘ENV['http_proxy']

When environment variable 'http_proxy' 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 'http' or 'https':

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 'Accept-Encoding' to a new request object:

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 'Content-Range'.

Otherwise decompression (or not) depends on the value of header Content-Encoding:

  • 'deflate', 'gzip', or 'x-gzip': decompresses the body and deletes the header.

  • 'none' or 'identity': does not decompress the body, but deletes the header.

  • Any other value: leaves the body and header unchanged.

:call-seq:

Net::HTTP.get(hostname, path, port = 80) -> body
Net::HTTP:get(uri, headers = {}, port = uri.port) -> body

Sends a GET request and returns the HTTP response body as a string.

With string arguments hostname and path:

hostname = 'jsonplaceholder.typicode.com'
path = '/todos/1'
puts Net::HTTP.get(hostname, path)

Output:

{
  "userId": 1,
  "id": 1,

  "completed": false
}

With URI object uri and optional hash argument headers:

uri = URI('https://jsonplaceholder.typicode.com/todos/1')
headers = {'Content-type' => 'application/json; charset=UTF-8'}

  • Has the default port number, Net::HTTP.default_port (80).

  • Has no proxy.

Example:

http = Net::HTTP.new(hostname)
# => #<Net::HTTP jsonplaceholder.typicode.com:80 open=false>
http.address # => "jsonplaceholder.typicode.com"
http.port    # => 80
http.proxy?  # => false

.start(address, *arg, &block) ⇒ Object

:call-seq:

HTTP.start(address, port = nil, p_addr = :ENV, p_port = nil, p_user = nil, p_pass = nil, opts) -> http
HTTP.start(address, port = nil, p_addr = :ENV, p_port = nil, p_user = nil, p_pass = nil, opts) {|http| ... } -> object

Creates a new Net::HTTP object, http, via Net::HTTP.new:

  • For arguments address and port, see Net::HTTP.new.

  • For proxy-defining arguments p_addr through p_pass, see Proxy Server.

  • For argument opts, see below.

With no block given:

  • Calls http.start with no block (see #start), which opens a TCP connection and HTTP session.

  • Returns http.

  • The caller should call #finish to close the session:

    http = Net::HTTP.start(hostname)
    http.started? # => true
    http.finish
    http.started? # => false
    

With a block given:

  • Calls http.start with the block (see #start), which:

    • Opens a TCP connection and HTTP session.

    • Calls the block, which may make any number of requests to the host.

    • Closes the HTTP session and TCP connection on block exit.

    • Returns the block’s value object.

  • Returns object.

Example:

hostname = 'jsonplaceholder.typicode.com'
Net::HTTP.start(hostname) do |http|
  puts http.get('/todos/1').body
  puts http.get('/todos/2').body
end

Output:

{
  "userId": 1,
  "id": 1,
  "title": "delectus aut autem",
  "completed": false
}
{
  "userId": 1,
  "id": 2,
  "title": "quis ut nam facilis et officia qui",
  "completed": false
}

If the last argument given is a hash, it is the opts hash, where each key is a method or accessor to be called, and its value is the value to be set.

The keys may include:

  • #ca_file

  • #ca_path

  • #cert

#startObject

Starts an HTTP session.

Without a block, returns self:

http = Net::HTTP.new(hostname)
# => #<Net::HTTP jsonplaceholder.typicode.com:80 open=false>
http.start
# => #<Net::HTTP jsonplaceholder.typicode.com:80 open=true>
http.started? # => true
http.finish

With a block, calls the block with self, finishes the session when the block exits, and returns the block’s value:

http.start do |http|
  http
end
# => #<Net::HTTP jsonplaceholder.typicode.com:80 open=false>
http.started? # => false

Raises:

  • (IOError)

#trace(path, initheader = nil) ⇒ Object

Sends a TRACE request to the server; returns an instance of a subclass of Net::HTTPResponse.

The request is based on the Net::HTTP::Trace object created from string path and initial headers hash initheader.

http = Net::HTTP.new(hostname)
http.trace('/todos/1')

end

#unlock(path, body, initheader = nil) ⇒ Object

Sends an UNLOCK request to the server; returns an instance of a subclass of Net::HTTPResponse.

The request is based on the Net::HTTP::Unlock object created from string path, string body, and initial headers hash initheader.

data = '{"userId": 1, "id": 1, "title": "delectus aut autem", "completed": false}'
http = Net::HTTP.new(hostname)
http.unlock('/todos/1', data)
