HTTP Methods - GET and DELETE

Demonstrate a method for sending HTTP requests that don't have a request body, such as for GET or DELETE requests. Ruby

require 'chilkat'

success = false

# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

http = Chilkat::CkHttp.new()

# Specifiy a session log file so we can see the exact request/response
http.put_SessionLogFilename("c:/aaworkarea/sessionLog.txt")

# Perhaps add a custom header or two..
http.SetRequestHeader("x-exz-date","20201012T235046Z")
http.SetRequestHeader("x-exz-id","1234")

# Send a GET request to https://www.example.com/someting?param1=123&param2=abc
url = "https://www.example.com/someting?param1=123&param2=abc"
resp = Chilkat::CkHttpResponse.new()
success = http.HttpNoBody("GET",url,resp)
if (success == false)
    print http.lastErrorText() + "\n";
    exit
end

# The GET request that is sent looks like this.
# The Accept and Accept-Encoding headers are automatically added by default.

# 	GET /someting?param1=123&param2=abc HTTP/1.1
# 	Host: www.example.com
# 	Accept: */*
# 	Accept-Encoding: gzip
# 	x-exz-date: 20201012T235046Z
# 	x-exz-id: 1234

# Get the response status
statusCode = resp.get_StatusCode()
print "Response status: " + statusCode.to_s() + "\n";

# Get the response body
print resp.bodyStr() + "\n";

# -------------------------------------------------------------
# Let's say we want to send a DELETE request, and we only want to accept an application/json response,
# and we don't want gzipped responses...

# First remove the previously specified custom headers.
http.ClearHeaders()

# Indicate we only accept application/json non-gzipped responses.
http.put_Accept("application/json")
http.put_AllowGzip(false)

# Send a DELETE request to https://www.example.com/deleteSomething
url = "https://www.example.com/deleteSomething"
success = http.HttpNoBody("DELETE",url,resp)
if (success == false)
    print http.lastErrorText() + "\n";
    exit
end

# The DELETE request that is sent looks like this.
# The empty Accept-Encoding header value means we only want non-compressed responses.

# 	DELETE /deleteSomething HTTP/1.1
# 	Host: www.example.com
# 	Accept: application/json
# 	Accept-Encoding: 

# Get the response status
statusCode = resp.get_StatusCode()
print "Response status: " + statusCode.to_s() + "\n";

# Get the response body
print resp.bodyStr() + "\n";
