I am sending data using the HTTP POST verb . But I am not receiving the data server side, despite the client reporting status-code 200. I can see the connection, and that the data was successfully sent, however, on the server, the data isn't found, with the log showing only the number of bytes.
How can I log the raw POST data that was sent to the server?
FYI, here the client is an embedded device with very limited capability, so this is a problem. I can not check print_r or echo.
You can see the content of any data sent with the post verb (not for production) with:
print_r($_POST);
If you want to see data from the verbs get, post, cookie:
print_r($_REQUEST);
If you need to log, since the client is very limited - try outputting the post data to a file:
file_put_contents("post.log", print_r($_POST, true));
file_put_contents("gpc.log", print_r($_REQUEST, true));
Write post data to a file:
file_put_contents('/tmp/postdata.txt', var_export($_POST, true));
To get the raw post from php you must use file_get_contents("php://input").
This will allow you to capture the raw body of the request, instead of form-data only ($_POST).
That said, you can use
file_put_contents("post.log", file_get_contents("php://input"));
This will allow you to log POST requests with Json data, and other stuff in its body.
