HTTPS GET URL with URL Encoded Query Params

See more HTTP Examples

Creates a URL with URL encoded query params, and sends an HTTPS GET to the URL. Lua

local chilkat = require("chilkat")

local success = false

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

-- Create a URL with URL-encoded query params.
local sbUrl = chilkat.StringBuilder.new()
sbUrl:append("https://www.example.com/something?")

-- If we know a query param value does not have any special chars requiring URL encoding,
-- just add it.  In this case, there is no need to URL encode "123" because "123" url encoded is still just "123".
sbUrl:append("abc=123&xyz=")

local sbValue = chilkat.StringBuilder.new()
sbValue:append("this is a test")

sbUrl:append("msg=")
sbUrl:append(sbValue:get_encoded("url", "utf-8"))

-- sbUrl contains:  https://www.example.com/something?abc=123&xyz=msg=this%20is%20a%20test
print(sbUrl:get_as_string())

-- Send the GET request and get the response body, which is assumed to be text of some sort (HTML, XML, JSON, etc.)
-- (Chilkat automatically decompresses gzipped responses)
local http = chilkat.Http.new()
local responseBody = http:quick_get_str(sbUrl:get_as_string())
if not http.last_method_success then
    print(http.last_error_text)
    return
end

print("Response Body:")
print(responseBody)
