PHP CURL从CURL for Linux返回不同的结果

Question

I'm trying to work out why a call to a web service isn't returning the results I need.

Using CURL for Linux with

curl -i -H "Accept: application/json" "https://www.thisapi.com/stuff/?status=something" > myfile.txt

I get the correct results, an object starting: {"object_count": 4, ...

Using PHP with libcurl and

$curl = curl_init();
$hdr[] = 'Content-type: application/json';
$hdr[] = 'Accept: application/json';

curl_setopt($curl, CURLOPT_HTTPHEADER, $hdr);

$url = 'https://www.thisapi.com/stuff/?status=something';
curl_setopt($curl, CURLOPT_URL, $url);

//return the data
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

$results = curl_exec($curl);

Ignores the URL variable "status" and I get {"object_count": 8 ...

Can anyone help me to work out in which ways these two requests are not equivalent and therefore why they are not returning the same results?

Answer 1

In the second case you have an additional header you are sending - Content-type: application/json. Perhaps this is causing the API endpoint to respond differently, ignoring the parameter in the URL, as it is expecting something in JSON format.
