How to Post A Laravel Form With Curl From Cli?

3 minutes read

To post a Laravel form with curl from the command line interface (CLI), you can use the following command:

1
curl -X POST -d "data=value&another_data=another_value" http://your-laravel-app.com/form-endpoint


Replace data=value&another_data=another_value with the actual form data you want to post and http://your-laravel-app.com/form-endpoint with the endpoint where the form is submitted in your Laravel application. Make sure to use the -X POST option to specify the HTTP method as POST and -d to include the form data in the request.


What is the difference between CURLOPT_HTTPHEADER and CURLOPT_POSTFIELDS?

  • CURLOPT_HTTPHEADER is used to specify an array of custom headers to be sent with the HTTP request, such as authentication credentials, content type, or encoding information.
  • CURLOPT_POSTFIELDS is used to specify the data to be sent in the body of a POST request. It should be formatted as a string in the format expected by the server, such as URL-encoded data or JSON.


In summary, CURLOPT_HTTPHEADER is used to set custom headers, while CURLOPT_POSTFIELDS is used to set the data to be sent in the request body.


What is a curl_setopt function in PHP?

The curl_setopt function is a function in PHP that is used to set options for a cURL transfer. cURL is a library that allows you to connect and communicate with different servers using various protocols like HTTP, FTP, etc.


The curl_setopt function can be used to set various options for a cURL transfer, such as the URL to connect to, the request method (GET, POST, etc), headers to send, timeout values, and more. The function takes two parameters - the cURL handle and the option to set along with its value.


Here is an example of how you can use the curl_setopt function to set options for a cURL transfer:

// Initialize a new cURL handle
$ch = curl_init();

// Set the URL to connect to
curl_setopt($ch, CURLOPT_URL, 'http://example.com/api');

// Set the request method to POST
curl_setopt($ch, CURLOPT_POST, true);

// Set the data to send in the body of the request
curl_setopt($ch, CURLOPT_POSTFIELDS, 'param1=value1&param2=value2');

// Execute the cURL transfer
$response = curl_exec($ch);

// Close the cURL handle
curl_close($ch);


In this example, we are setting the URL to connect to, the request method to POST, and the data to send in the body of the request using the curl_setopt function.


How to process a JSON response in cURL?

To process a JSON response in cURL, you can use the following steps:

  1. Make a cURL request to the API endpoint that returns a JSON response. For example:
1
curl https://api.example.com/endpoint


  1. Save the JSON response to a file by using the -o option:
1
curl https://api.example.com/endpoint -o response.json


  1. Use a JSON parser tool like jq to process the JSON response. For example, to extract a specific field from the JSON response:
1
jq '.field_name' response.json


  1. You can also use grep or sed to further process the JSON response:
1
grep 'search_term' response.json


These are some ways you can process a JSON response in cURL. You can customize your approach based on your specific requirements and the structure of the JSON response.
