PHP Using cURL and GET request with a header
According to PHP documentation for CURLOPT_HEADER
:
TRUE to include the header in the output.
Your $response
will probably look like this:
HTTP/1.1 200 OK
Some: headers
More: header lines
{
"real": "json content"
}
This is because you added the CURLOPT_HEADER
option.
You don't need to set any options to let the curl request send your headers. As long as you set the CURLOPT_HTTPHEADER
option, the headers will be sent.
If you really want to receive the response headers too, check existing questions like "Can PHP cURL retrieve response headers AND body in a single request?"

There are slimier questions in the past like below.
How do I send a GET request with a header from PHP?
But I don't know why my code is not working. I want to get "status code 200 OK and image data in binary" by using cURL and GET request with a header.
I may make mistake on debugging too. I would appreciate your any help. Thanks in advance!
API refrence: https://devdocs.line.me/en/#get-content
$url = "https://api.line.me/v2/bot/message/". $message_id. "/content"; $curl = curl_init("$url"); error_log(var_export($curl)); curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); // 証明書の検証を行わない curl_setopt($curl, CURLOPT_HTTPHEADER, array( 'Authorization: Bearer ' . $accessToken, )); $response = curl_exec($curl); $header_size = curl_getinfo($curl, CURLINFO_HEADER_SIZE); $header = substr($response, 0, $header_size); $image_binary = substr($response, $header_size); curl_close($curl); error_log(print_r("xxx...",true)); error_log(var_export($response)); error_log(print_r("aaa...",true)); error_log(print_r($response,true)); error_log(print_r("bbb...",true)); error_log(print_r($header,true)); error_log(print_r("ccc...",true)); error_log(print_r($image_binary,true));
Then.. I get this...

TKasai over 7 yearsIve deleted "CURLOPT_HEADER" but still can't get a Json.

SOFe over 7 yearsDump your
$response
to see if you have got what you expected, and usejson_last_error_msg
to see the exact error. -
TKasai over 7 yearsIve tried "error_log(print_r("error is : ".json_last_error(),true));". The result is "5." Does this mean, JSON_ERROR_UTF8??
-
SOFe over 7 yearsPrint your
$response
, then you will see what is wrong with the JSON... -
