CSV file upload in Php using curl - php

Question

I am using Php as a frontend and Java as a backend. I have created an Post API for uploading file and using curl for api request.
I have hit my Api using Postman at that time it works fine but i am facing prodblem when i request api using Curl i don't eble to get what i am doing wrong.
Here is the curl requested data :-
$data2 = array(
'file' =>
'#' . $data1->file->tmp_name
. ';filename=' . $data1->file->name
. ';type=' . $data1->file->type
);
This is how i am sending curl request:-
$ch = curl_init();
curl_setopt($ch, CURLOPT_TIMEOUT, 120);
curl_setopt($ch,CURLOPT_URL,$this->url);
curl_setopt($ch, CURLOPT_HEADER, 1); //parveen
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1); //parveen
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS,$data2);
$headers = array(
'Content-Type:'.$this->service->contentType,
'Launcher:'.$this->serverName,
'domain:'.$this->service->domain,
);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$this->responseBody=curl_exec($ch);

the way you're trying to upload the file hasn't been supported since the PHP5 days, and even in 5.5+ you'd need CURLOPT_SAFE_UPLOAD to upload with #. use CURLFile when uploading files, like
$data2 = array(
'file' => new CURLFile($data1->file->name,$data1->file->type,$data1->file->tmp_name)
);
also, don't use CURLOPT_CUSTOMREQUEST for POST requests, just use CURLOPT_POST. (this is also true for GET requests and CURLOPT_HTTPGET )
also, check the return value of curl_setopt, if there was a problem setting your option, it returns bool(false), in which case you should use curl_error() to extract the error message. use something like
function ecurl_setopt($ch,int $option,$value){
if(!curl_setopt($ch,$option,$value)){
throw new \RuntimeException('curl_setopt failed! '.curl_error($ch));
}
}
and protip, whenever you're debugging curl code, use CURLOPT_VERBOSE, it prints lots of useful debugging info
