卷曲不打印结果

Question

I've run manually the url from postman, and I've successfully connected and it printed it results.

But when I tried calling it from a method, no result is printing.

here's the curl code I used:

public function curlHandle($apiPath, $postArray)
{
    $CI = & get_instance();
    $conf = $CI->config->config;
    $curlHandle = curl_init($apiPath);
    curl_setopt($curlHandle, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curlHandle, CURLOPT_USERAGENT,"Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.57 Safari/537.36");
    curl_setopt($curlHandle, CURLOPT_TIMEOUT , 300);
    curl_setopt($curlHandle, CURLOPT_POST, 1);
    curl_setopt($curlHandle, CURLOPT_POSTFIELDS, $postArray);
    curl_setopt($curlHandle, CURLOPT_VERBOSE, 1);
    $fp = fopen('/var/www/html/logs/curl_log.txt', 'w');
    curl_setopt($curlHandle, CURLOPT_STDERR, $fp);
    $result = curl_exec($curlHandle);
    print_r(curl_error($curlHandle));
    if ($result === FALSE) {
        die(curl_error($curlHandle));
    } else {
         $data = json_decode($result, TRUE);
    }
    curl_close($curlHandle);
    return $data;

}

Here's the content of curl_log.txt

• Hostname localhost/codeignitertest was found in DNS cache

also note that curlHandle() is from another project and localhost/codeignitertest but both are running in my localhost

Answer 1

You've issued this option:

curl_setopt($curlHandle, CURLOPT_RETURNTRANSFER, true);

Which means that curl returns the output from the remote server instead of printing it.

You then capture that output into a variable:

$result = curl_exec($curlHandle);

Which you then encode and return to your caller:

return $data;

This code shouldn't print the results. It returns the results.
