Curl not returning values

Recommended Posts

I am trying to get to a site with the following code:

	        $syms ="T,IBM";
        $closeDict = array();    
        $url = "https://api.iextrading.com/1.0/stock/market/batch?types=quote&filter=symbol,latestPrice,&symbols="+$syms;
           $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);    
    
           $jresult = curl_exec($ch);
           $info = curl_getinfo($ch);
        echo(print_r($info));
        echo("alertjresult is ".$jresult);
	

and several things are or are not happening. 

1) the url doesn't get put into the header

2) There is no response Notice the alerts at the end.

I seem to recall reading that there is an option to set when accessing a https site.  However there is no password or other sign in function.  If you cut and paste the url into a browser it operates just fine.

What I have I overlooked??

[code}]

Array ( => http://0/ [content_type] => [http_code] => 0 [header_size] => 0 [request_size] => 0 [filetime] => -1 [ssl_verify_result] => 0 [redirect_count] => 0 [total_time] => 1.594 [namelookup_time] => 0 [connect_time] => 0 [pretransfer_time] => 0 [size_upload] => 0 [size_download] => 0 [speed_download] => 0 [speed_upload] => 0 [download_content_length] => -1 [upload_content_length] => -1 [starttransfer_time] => 0 [redirect_time] => 0 [redirect_url] => [primary_ip] => [certinfo] => Array ( ) [primary_port] => 0 [local_ip] => [local_port] => 0 ) 1alertjresult is alertresult is

the url doesn't get put into the header

What does that mean?

The first element in the array says http://0/, so your URL is "0".  That's because you're using the plus sign on the line where you define the URL, and the plus sign is for addition.  You use a dot to concatenate strings.

OK, My error moving from Javascript to PHP. Fixed that and now get but still nothing back

			 		Array ( [url] => https://api.iextrading.com/1.0/stock/market/batch?types=quote&filter=symbol,latestPrice,&symbols=T,IBM [content_type] => [http_code] => 0 [header_size] => 0 [request_size] => 0 [filetime] => -1 [ssl_verify_result] => 20 [redirect_count] => 0 [total_time] => 0.156 [namelookup_time] => 0.047 [connect_time] => 0.11 [pretransfer_time] => 0 [size_upload] => 0 [size_download] => 0 [speed_download] => 0 [speed_upload] => 0 [download_content_length] => -1 [upload_content_length] => -1 [starttransfer_time] => 0 [redirect_time] => 0 [redirect_url] => [primary_ip] => 35.224.167.123 [certinfo] => Array ( ) [primary_port] => 443 [local_ip] => 10.0.0.167 [local_port] => 53785 ) 1alertjresult is alertresult is	

putting the url  into a browser gives the answer result as
 
{"T":{"quote":{"symbol":"T","latestPrice":32.97}},"IBM":{"quote":{"symbol":"IBM","latestPrice":145.23}}}
Now what is missing??

Just to close the loop and in case others are looking for the same solution.

I put in the line "echo 'Curl error: '.curl_error($ch);" and found that the error was SSL

Then since putting the url in the browser didn't ask for any user name and password I added the following line to the curl options

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

The false parameter says something to the effect 'don't care about verifying' and allows it to do its thing.

and it works!!

Thanks for getting me on the right path.
