It depends how you are sending data to the route. This is a POST route, so it will expect the body data to standard form format (application/x-www-form-urlencoded) by default.

这取决于您如何将数据发送到路由。这是一个POST路径，因此默认情况下，它将期望body数据到标准表单格式(应用程序/x-www-form-urlencode)。

If you are sending JSON to this route, then you need to set the Content-type header to application/json. i.e. the curl would look like:

如果将JSON发送到此路由，则需要将Content-type头设置为application/ JSON。即旋度是这样的

curl -X POST -H "Content-Type: application/json" \
  -d '{"email": "a@example.com"}' http://localhost/

Also, you should validate that the array key you are looking for is there:

此外，您应该验证所查找的数组键是否存在:

$parsedBody = $request->getParsedBody()
$email = $parsedBody['email'] ?? false;

Please, try this way:

请试试这个方法:

$app-> post('/yourFunctionName', function() use ($app) {
  $parameters = json_decode($app->request()->getBody(), TRUE);
  $email = $parameters['email'];
  var_dump($email);
});

I hope this helps you!
