Upgrade Guide

Upgrading from v6 to v7

CFHttp HTTP Client

This client now returns more accurate status codes for 502 Bad Gateway and 408 Request Timeout responses.

If you were previously checking specifically for 504 status codes for bad hosts, you need to now either check for 502 status codes or use a more general method, like isServerError or isError.

If you were previously checking specifically for 504 status codes or isServerError for timed out requests, you need to now either check for 408 status codes, isClientError, or the more general isError.

Upgrading from v5 to v6

• The default Content-Type header has been removed. You must set this manually or use a format helper, such as asJson.

• Dropped support for Adobe 2016.

Upgrading from v4 to v5

HyperHttpClientInterface now requires a debug method.

/**
 * Return a struct of information showing how the client will execute the HyperRequest.
 * This will be used by a developer to debug any differences between the generated
 * request values and the expected request values.
 *
 * @req     The HyperRequest to debug.
 *
 * @returns A struct of information detailing how the client would execute the HyperRequest.
 */
public struct function debug( required HyperRequest req );

Upgrading from v3 to v4

Previously, query params were stored as a struct. Some APIs expect multiple values for the same query param name to be passed as separate arguments. Hyper now stores the query params as an array and provides new methods for interacting with query params:

• getQueryParamByName
• getAllQueryParamsByName
• withQueryParams
• appendQueryParam
• appendQueryParams
• hasQueryParam

The following methods still exist, but now interact with arrays of query param structs instead of a simple struct.

• getQueryParams
• setQueryParams

The following methods have been deprecated:

Deprecated Method	Replacement Method
getQueryParam	getQueryParamByName
