Chilkat.OAuth1

Generate OAuth 1.0 signatures, authorization headers, and signed request URLs.

Chilkat.OAuth1 builds the signed OAuth 1.0 authentication data needed for APIs that still require OAuth 1.0 request signing. It can generate the signature base string, HMAC key, signature, URL-encoded signature, normalized signed parameter string, Authorization header, and generated URL containing OAuth query parameters. It supports consumer credentials, access tokens, nonce and timestamp generation, extra signed parameters, optional realm handling, HMAC-SHA1, HMAC-SHA256, RSA-SHA1, and RSA-SHA256 signing.

OAuth 1.0 signing

Generate the OAuth 1.0 signature and related authentication values from the HTTP method, request URL, credentials, token, nonce, and timestamp.

Authorization header

Produce the value to send in the HTTP Authorization header when OAuth parameters should be supplied as a header.

Signed URL output

Generate a URL that includes the OAuth 1.0 query parameters when the API expects authentication data in the request URL.

Extra signed parameters

Add or remove request-specific name/value parameters that must be included in the normalized parameter string and signature calculation.

HMAC or RSA signatures

Sign with HMAC-SHA1, HMAC-SHA256, RSA-SHA1, or RSA-SHA256, with RSA private keys supplied by SetRsaKey.

Debuggable signing details

Inspect the exact BaseString, HmacKey, QueryString, Signature, and EncodedSignature used to build the OAuth request.

Common pattern: Set OauthMethod and OauthUrl, provide the consumer key and secret, set any token and token secret, generate or assign Nonce and Timestamp, add request parameters with AddParam, then call Generate. Use AuthorizationHeader when sending OAuth data in an HTTP header, or GeneratedUrl when the signed OAuth parameters should be placed in the URL.
URL guidance: Set OauthUrl to the base request URL without query parameters. Add query parameters separately with AddParam so they are included correctly in the OAuth 1.0 signature calculation.

Object Creation

local chilkat = require("chilkat")

local oauth1 = chilkat.OAuth1.new()
local oauth1 = chilkat.OAuth1.new()

Creates the object (chilkat.OAuth1() does the same). Lua's garbage collector frees it when it is no longer referenced; oauth1:dispose() frees it at once, and in Lua 5.4 and later local oauth1 <close> = chilkat.OAuth1.new() frees it when the block ends. Calling a method of a disposed object raises an error.

Errors

A method that fails returns nil followed by the error text, as io.open does: local body, err = oauth1:method(...), where err is the object's last_error_text. Wrap the call in assert() to raise an error with that text instead. Methods that answer a question return true or false, numbers are returned as they are (check last_method_success where the description says a value means failure), and property reads and writes never fail for Chilkat reasons.

Misuse raises a Lua error: a wrong argument type or a missing argument (bad argument #1 to ...), an unknown property name, a write to a read-only property, an out-of-range integer, or an object of the wrong class.

Names are Chilkat's in snake_case: QuickGetStr is quick_get_str, LastErrorText is last_error_text. Properties are fields (oauth1.verbose_logging = true) and methods use the colon (oauth1:method(...)). Strings are UTF-8; binary data is a Lua string of bytes. Indexes are 0-based, as in every Chilkat API. Unlocking: call chilkat.unlock_bundle("...") once at startup.

Properties

AuthorizationHeader
-- strVal is a string (read-only)
local strVal = oauth1.authorization_header
Introduced in version 9.5.0.53

The authorization header. This is what would be included in the Authorization HTTP request header if it is going to be used as the means for providing the OAuth1 authorization information.

top
BaseString
-- strVal is a string (read-only)
local strVal = oauth1.base_string
Introduced in version 9.5.0.53

This is the exact string that was signed. For example, if the signature method is HMAC-SHA1, the BaseString is the exact string that passed to the HMAC-SHA1. An application does not set the BaseString property. The BaseString is exposed as a property to allow for debugging and to see the exact string that is signed.

top
ConsumerKey
-- strVal is a string
local strVal = oauth1.consumer_key
oauth1.consumer_key = strVal
Introduced in version 9.5.0.53

The consumer key.

top
ConsumerSecret
-- strVal is a string
local strVal = oauth1.consumer_secret
oauth1.consumer_secret = strVal
Introduced in version 9.5.0.53

The consumer secret.

top
DebugLogFilePath
-- strVal is a string
local strVal = oauth1.debug_log_file_path
oauth1.debug_log_file_path = strVal

If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.

Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.

Possible causes of hangs include:

  • A timeout property set to 0, indicating an infinite timeout.
  • A hang occurring within an event callback in the application code.
  • An internal bug in the Chilkat code causing the hang.

More Information and Examples
top
EncodedSignature
-- strVal is a string (read-only)
local strVal = oauth1.encoded_signature

top
HmacKey
-- strVal is a string (read-only)
local strVal = oauth1.hmac_key
Introduced in version 9.5.0.53

The exact HMAC key used to sign the BaseString. An application does not directly set the HmacKey. The HmacKey property is read-only and is provided for debugging to see the exact HMAC key used to sign the BaseString. The HMAC key is composed from the consumer secret (if it exists) and the token secret (if it exists).

top
LastErrorHtml
-- strVal is a string (read-only)
local strVal = oauth1.last_error_html

Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

top
LastErrorText
-- strVal is a string (read-only)
local strVal = oauth1.last_error_text

Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

top
LastErrorXml
-- strVal is a string (read-only)
local strVal = oauth1.last_error_xml

Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

top
LastMethodSuccess
-- boolVal is a boolean
local boolVal = oauth1.last_method_success
oauth1.last_method_success = boolVal

Indicates the success or failure of the most recent method call: true means success, false means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages. Note: This property does not apply to methods that return integer values or to boolean-returning methods where the boolean does not indicate success or failure.

top

Note: The OAuthUrl should not include query parameters. For example, do not set the OAuthUrl equal to

https://rest.sandbox.netsuite.com/app/site/hosting/restlet.nl?script=165&deploy=1
Instead, set OAuthUrl equal to
https://rest.sandbox.netsuite.com/app/site/hosting/restlet.nl

This is a catch-all property to be used for uncommon needs. This property defaults to the empty string and should typically remain empty.

Can be set to a list of the following comma separated keywords:

  • INCLUDE_REALM - Introduced in v9.5.0.85. Include the Realm in the signature calculation and outputs.

top
VerboseLogging
-- boolVal is a boolean
local boolVal = oauth1.verbose_logging
oauth1.verbose_logging = boolVal

If set to true, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is false. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

top
Version
