将JSON作为请求正文发送或将POST JSON发送到变量中

Question

I am trying to figure out, is there any way of sending raw json to php instead of POST parameter. If it is possible then which way is best i mean either request body or POST parameter.

Answer 1

Send an HTTP request which has a JSON string as its request body (here: using curl on the command line):

$ curl -d '{"foo":"bar"}' example.com/test.php

Read this request body in PHP:

$json = file_get_contents('php://input');

Decode it:

$data = json_decode($json, true);

PHP's $_POST superglobal is automatically populated as an array if the request body of a POST request contains URL encoded key-value pairs (eg foo=bar&baz=42 ). In the above example you're still using an HTTP POST request with "POST data". It just doesn't automatically end up in $_POST because PHP doesn't know how to decode JSON automagically.
