PHP + Guzzle, Sending Authorization Key in Header

Question

I'm new to Guzzle and I'm attempting to generate the following REST call:

https://product-search.api.cj.com/v2/product-search?website-id=1594990&keywords=%2Bsony+-camera

GET /v2/product-search?website-id=1594990&keywords=%2Bsony+-camera HTTP/1.1

I am using the following PHP code:

$client = new Client('https://linksearch.api.cj.com', array(
    'id' => $website_id,
    'keywords' => 'sony',
));
$request = $client->get("v2/link-search?website-id={id}&keywords={keywords}");
$request->addHeader('Authorization', $dev_key);
$response = $request->send();

The issue here is that with the addHeader() statement I get the response "Bad Request" and without addHeader() I am getting "Unauthorized". It would seem that I am not properly sending my authentication information. Does anyone know what I'm doing wrong here?

Answer 1

The actual issues here were:

1) The header 'authorization' may be case sensitive and may need to be lowercase.

2) A 400 error will be thrown if any of the request parameters are incorrect, even your website-id. A 400 error means "The request was invalid for reasons other than authentication."

Answer 2

I think you're creating the $request incorrectly. Try this:

$client = new Client();
$request = new Request('POST', 'http://someuri/path/here');

Then send the request using $client:

$response = $client->send($request);
