Those parameters are specified in CURLOPT_POSTFIELDS option. Note that, when setting the URL, we just set the URL itself without the parameters, that’s for GET requests. POST requestsįor POST requests, we have to configure the cURL options in a slightly different way:ĬURLOPT_POSTFIELDS => stringifyParameters(), We will see that the output generated by the script, is the same of that which we would have received making a search in the above search box, in this page, entering php.
We can test this script, entering, for example, localhost/path/to/curl_get.php?url=&s=php in the browser.
Finally, when we have ended the cURL session handling, we must close it, curl_close() function. In this case, as we configured the CURLOPT_RETURNTRANSFER option, we can save the response value into a variable. If any error has occurred initializing and configuring the cURL session, we can proceed to execute it, just calling curl_exec() function, specifying for which session we are executing the request. When false is returned, we can get the information of the last error for the given cURL session with curl_error() function, as in lines 69 and 75. We should always check that the cURL functions don’t return any errors, checking the return values of the functions. 
If set to false, the response will be printed directly. This allows to save the HTTP response into a variable.
The CURLOPT_RETURNTRANSFER option to true. If we set to false, and the specified URL makes a redirection, we won’t reach the final URL. This is for following the 3XX HTTP redirections. The CURLOPT_FOLLOWLOCATION option to true. Note how is the parameter string constructed in stringifyParameters() function: the values should be encoded to URL encoding, with urlencode() function (lines 24 and 25). For GET requests, we just have to specify the URL with the parameter string, in key=value format, as you already know. In this case, we have configured it with the following options: Once we have created successfully the cURL session, we have to configure it, as we do with curl_setopt_array() function. If some error occurs, false will be returned, so we have to check it before continuing (line 43). First, we created a cURL session, with curl_init() function, as in line 41. curl_error($curl)) Ĭurl_close($curl) // Don't forget to close! stringifyParameters(),ĭie('An error occured: '. * The cURL request to the url false if an error occurs.ĬURLOPT_URL => $url. * Creates the cURL request for the given URL. Let’s see how we can use cURL to create GET requests: In /etc/php/apache2/php.ini file, we need to include the cURL extension, in order to use it: extension=php_curl.soĭon’t forget to restart Apache after doing any change.

Installationīelow, commands to install Apache, PHP and PHP cURL library are shown: sudo apt-get update I’m sure that it’s just my understanding which is holding me back from being able to make a request like this through Postman, though I have successfully done it before using XAMPP.īelow is the PHP request which I need to make, as well as a few of the different endpoints available to fetch data from.ĭoes anyone know if this is possible with Postman? I’ve tried using the “Import -> Paste Raw Text / Upload File” methods although it keeps saying the format is unrecognized.You may skip environment preparation and jump directly to the beginning of the example below. It seems pretty straight-forward with making requests to REST API based servers, although I need to make a very specific PHP cURL request to another server in order to obtain an MD5 encoded hash key to authorize my request. I’ve just downloaded Postman and learning to get started.
