Craft 3 version: There won't be a Craft 3 port of this plugin, as the Craft Fetch plugin, available for Craft 3, provides a similar list of features.

HTTP Request plugin for Craft CMS

Create and send HTTP requests from templates and retrieve the response, in JSON or plain text.

Installation

1. Copy the "httpreq" directory into "craft/plugins".
2. Open the control panel and go to "Settings > Plugins".
3. Install the "HTTP Request" plugin.

Usage

Once the plugin has been installed, you may access it through the "craft.httpReq" variable in the templates. Here is an overview of the available methods:

get

Sends a GET request to the specified endpoint.

Parameters:

• url: Complete URL to which you want to send the request
• params: Hash containing the parameters names and values
• fromCache: Boolean to specify if the response should be fetch from cache. True by default.
• additionalOptions: Optional array containing options to further modify the request. Currently only supports the addition of custom headers.

Example:

craft.httpReq.get('http://domain.com/api/test', { "lang" : "fr" }, false)

This code will try to make a GET request to http://domain.com/api/test?lang=fr without trying to get the response from cache.

{
	"statusCode": 200,
	"body": (parsed JSON object),
	"erro": "Contains the error message, if any"
}

In order to insert custom headers in the request, use the additional options array. Example:

craft.httpReq.get('http://domain.com/api/test', { "lang" : "fr" }, false, {
    headers: {
        "X-Custom-Header": "foo"
    }
})

post

Sends a POST request to the specified endpoint. POST requests are never fetched from cache.

Parameters:

• url: Complete URL to which you want to send the request
• params: Hash containing the parameters names and values
• files: A hash containing file input names and their corresponding handles.
• additionalOptions: Optional array containing options to further modify the request. Currently only supports the addition of custom headers.

Example:

craft.httpReq.post('http://domain.com/api/test', { "fname" : "John", "lname" : "Doe" }, { "cv": (UploadFile) })

This code will try to make a POST request to http://domain.com/api/test with the following parameters encoded using multipart/form-data: fname, lname, cv. The value for the CV parameter is the content of the file.

Return value:

{
	"statusCode": 200,
	"body": (parsed JSON object),
	"erro": "Contains the error message, if any"
}

setCacheTtl

To be called before a request is being done. It can be used to specify the number of seconds during which the cache should be active.

Parameters:

• ttl: Integer. Number of seconds during which the elements put in cache will stay valid

Example:

craft.httpReq.setCacheTtl(60)

This will define a cache validity time of 1 minute for all further requests.

getParams

Helper method to safely retrieve a list of parameters (GET or POST) from the current Craft request.

Parameters:

• paramNames: Array containing names of parameters to retrieve

Example:

craft.httpReq.getParams(['fname','lname'])

Return value:

{ "fname": "John", "lname": "Doe" }

getFiles

Helper method to retrieve a list of uploaded files from the current Craft request.

Parameters:

• paramNames: Array containing the names of the file inputs

Example:

craft.httpReq.getFiles(['cv'])

Return value:

{ "cv": (UploadFile) }

Cache

We use Craft's caching system to store the responses. The TTL is of 1 hour per default, but this value can be changed using the setCacheTtl method.

Session handling

As this plugin was mainly created with the idea to query REST API, the session handling is not really at its best. We create a single CookieJar in memory that remains during the whole Craft request.
