Results for: "String# "

Returns a new closure wrapper for the name function.

• ctype is the return type of the function

• argtype is an Array of arguments, passed to the callback function

• call_type is the abi of the closure

• block is passed to the callback

See Fiddle::Closure

Writes s to the buffer. When the buffer is full or sync is true the buffer is flushed to the underlying socket.

Writes s in the non-blocking manner.

If there is buffered data, it is flushed first. This may block.

write_nonblock returns number of bytes written to the SSL connection.

When no data can be written without blocking it raises OpenSSL::SSL::SSLError extended by IO::WaitReadable or IO::WaitWritable.

IO::WaitReadable means SSL needs to read internally so write_nonblock should be called again after the underlying IO is readable.

IO::WaitWritable means SSL needs to write internally so write_nonblock should be called again after underlying IO is writable.

So OpenSSL::Buffering#write_nonblock needs two rescue clause as follows.

# emulates blocking write.
begin
  result = ssl.write_nonblock(str)
rescue IO::WaitReadable
  IO.select([io])
  retry
rescue IO::WaitWritable
  IO.select(nil, [io])
  retry
end

Note that one reason that write_nonblock reads from the underlying IO is when the peer requests a new TLS/SSL handshake. See the openssl FAQ for more details. www.openssl.org/support/faq.html

By specifying a keyword argument exception to false, you can indicate that write_nonblock should not raise an IO::Wait*able exception, but return the symbol :wait_writable or :wait_readable instead.

A wrapper class to use a StringIO object as the body and switch to a TempFile when the passed threshold is passed. Initialize the data from the query.

Handles multipart forms (in particular, forms that involve file uploads). Reads query parameters in the @params field, and cookies into @cookies.

Sets the value for field 'Range'; see Range request header:

With argument length:

req = Net::HTTP::Get.new(uri)
req.set_range(100)      # => 100
req['Range']            # => "bytes=0-99"

With arguments offset and length:

req.set_range(100, 100) # => 100...200
req['Range']            # => "bytes=100-199"

With argument range:

req.set_range(100..199) # => 100..199
req['Range']            # => "bytes=100-199"

Net::HTTPHeader#range= is an alias for Net::HTTPHeader#set_range.

Returns the value of field 'Content-Length' as an integer, or nil if there is no such field; see Content-Length request header:

res = Net::HTTP.get_response(hostname, '/nosuch/1')
res.content_length # => 2
res = Net::HTTP.get_response(hostname, '/todos/1')
res.content_length # => nil

Sets the value of field 'Content-Length' to the given numeric; see Content-Length response header:

_uri = uri.dup
hostname = _uri.hostname           # => "jsonplaceholder.typicode.com"
_uri.path = '/posts'               # => "/posts"
req = Net::HTTP::Post.new(_uri)    # => #<Net::HTTP::Post POST>
req.body = '{"title": "foo","body": "bar","userId": 1}'
req.content_length = req.body.size # => 42
req.content_type = 'application/json'
res = Net::HTTP.start(hostname) do |http|
  http.request(req)
end # => #<Net::HTTPCreated 201 Created readbody=true>

Returns a Range object representing the value of field 'Content-Range', or nil if no such field exists; see Content-Range response header:

res = Net::HTTP.get_response(hostname, '/todos/1')
res['Content-Range'] # => nil
res['Content-Range'] = 'bytes 0-499/1000'
res['Content-Range'] # => "bytes 0-499/1000"
res.content_range    # => 0..499

Returns the leading (‘type’) part of the media type from the value of field 'Content-Type', or nil if no such field exists; see Content-Type response header:

res = Net::HTTP.get_response(hostname, '/todos/1')
res['content-type'] # => "application/json; charset=utf-8"
res.main_type       # => "application"

returns a Time that represents the Last-Modified field.
