Returns serialized iseq binary format data as a String object. A corresponding iseq object is created by RubyVM::InstructionSequence.load_from_binary() method.
String extra_data will be saved with binary data. You can access this data with RubyVM::InstructionSequence.load_from_binary_extra_data(binary).
Note that the translated binary data is not portable. You can not move this binary data to another machine. You can not use the binary data which is created by another version/another architecture of Ruby.
Takes source, which can be a string of Ruby code, or an open File object. that contains Ruby source code. It parses and compiles using prism.
Optionally takes file, path, and line which describe the file path, real path and first line number of the ruby code in source which are metadata attached to the returned iseq.
file is used for ‘__FILE__` and exception backtrace. path is used for require_relative base. It is recommended these should be the same full path.
options, which can be true, false or a Hash, is used to modify the default behavior of the Ruby iseq compiler.
For details regarding valid compile options see ::compile_option=.
RubyVM::InstructionSequence.compile_prism("a = 1 + 2") #=> <RubyVM::InstructionSequence:<compiled>@<compiled>> path = "test.rb" RubyVM::InstructionSequence.compile_prism(File.read(path), path, File.expand_path(path)) #=> <RubyVM::InstructionSequence:<compiled>@test.rb:1> file = File.open("test.rb") RubyVM::InstructionSequence.compile_prism(file) #=> <RubyVM::InstructionSequence:<compiled>@<compiled>:1> path = File.expand_path("test.rb") RubyVM::InstructionSequence.compile_prism(File.read(path), path, path) #=> <RubyVM::InstructionSequence:<compiled>@/absolute/path/to/test.rb:1>
Take a location from the prism parser and set the necessary instance variables.
Posts data to a host; returns a Net::HTTPResponse object.
Argument url must be a URI; argument data must be a hash:
_uri = uri.dup _uri.path = '/posts' data = {title: 'foo', body: 'bar', userId: 1} res = Net::HTTP.post_form(_uri, data) # => #<Net::HTTPCreated 201 Created readbody=true> puts res.body
Output:
{
"title": "foo",
"body": "bar",
"userId": "1",
"id": 101
}
Sets the write timeout, in seconds, for self to integer sec; the initial value is 60.
Argument sec must be a non-negative numeric value:
_uri = uri.dup _uri.path = '/posts' body = 'bar' * 200000 data = <<EOF {"title": "foo", "body": "#{body}", "userId": "1"} EOF headers = {'content-type': 'application/json'} http = Net::HTTP.new(hostname) http.write_timeout # => 60 http.post(_uri.path, data, headers) # => #<Net::HTTPCreated 201 Created readbody=true> http.write_timeout = 0 http.post(_uri.path, data, headers) # Raises Net::WriteTimeout.
Sets the continue timeout value, which is the number of seconds to wait for an expected 100 Continue response. If the HTTP object does not receive a response in this many seconds it sends the request body.
Sends a GET request to the server; forms the response into a Net::HTTPResponse object.
The request is based on the Net::HTTP::Get object created from string path and initial headers hash initheader.
With no block given, returns the response object:
http = Net::HTTP.new(hostname) http.request_get('/todos') # => #<Net::HTTPOK 200 OK readbody=true>
With a block given, calls the block with the response object and returns the response object:
http.request_get('/todos') do |res| p res end # => #<Net::HTTPOK 200 OK readbody=true>
Output:
#<Net::HTTPOK 200 OK readbody=false>
Sends a HEAD request to the server; returns an instance of a subclass of Net::HTTPResponse.
The request is based on the Net::HTTP::Head object created from string path and initial headers hash initheader.
http = Net::HTTP.new(hostname) http.head('/todos/1') # => #<Net::HTTPOK 200 OK readbody=true>
Sends an HTTP request to the server; returns an instance of a subclass of Net::HTTPResponse.
The request is based on the Net::HTTPRequest object created from string path, string data, and initial headers hash header. That object is an instance of the subclass of Net::HTTPRequest, that corresponds to the given uppercase string name, which must be an HTTP request method or a WebDAV request method.
Examples:
http = Net::HTTP.new(hostname) http.send_request('GET', '/todos/1') # => #<Net::HTTPOK 200 OK readbody=true> http.send_request('POST', '/todos', 'xyzzy') # => #<Net::HTTPCreated 201 Created readbody=true>
Posts data to a host; returns a Net::HTTPResponse object.
Argument url must be a URI; argument data must be a hash:
_uri = uri.dup _uri.path = '/posts' data = {title: 'foo', body: 'bar', userId: 1} res = Net::HTTP.post_form(_uri, data) # => #<Net::HTTPCreated 201 Created readbody=true> puts res.body
Output:
{
"title": "foo",
"body": "bar",
"userId": "1",
"id": 101
