http post sending json data by python to server

[erfan shaigani]

hi , in the python requests POST tutorial in the site , there is this piece of code ,

url = 'https://ipaddress of my server .../myphp.php'
myjson = {'somekey': 'somevalue'}

x = requests.post(url, json = myjson)
 

it sends the json data to a php file in a server that i have access to

how can I access json data in myphp.php file in the server ???

thanks

I'm not sure how Python is sending the data, but your PHP code will depend on the format of the data.

Assuming that Python is sending a JSON string, you can read the string using file_get_contents('php://input') and transform it into an array or object using json_decode().

<?php
$input = file_get_contents('php://input');
$data = json_decode($input, true);

// Print out the structure for testing
var_dump($data);

?>

From PHP's end, you would use the $_FILES array as in this tutorial: https://www.w3schools.com/php/php_file_upload.asp

I'm not familiar with Python's libraries, but if you can't find a library to upload files you're going to have to manually build the body of a file upload HTTP request which is not that easy. An easier alternative is to send a POST request where one variable contains the file contents and another variable contains the name of the file.

Whichever way you do it, you should do some validation on the PHP end to prevent people from using this as a gateway to hack into your server. If they manage to upload a PHP file or another kind of executable file then they can do anything.
