HTTPRequest Post value return response_code 400

Question

I try to follow godot documentation and implement function _ make_ post_ request. But result only shows null with response code returned 400. Anyone please help me.

My godot script:

func _make_post_request(url, data_to_send, use_ssl):
    var query = JSON.print(data_to_send)
    var headers = ["Content-Type: application/json"]
    $HTTPRequest.request(url, headers, use_ssl, HTTPClient.METHOD_POST, query)

func _on_Button_pressed():
   _make_post_request("http://localhost/buymall/site/test","hello world",true)

php script:

public function actionTest(){
$day = array(
        "monday"=>"1",
        "tuesday"=>"2",
        "wednesday"=>"3",
        "thursday"=>"4",
        "friday"=>"5",
        "saturday"=>"6",
        "sunday"=>"7",
    );

    echo json_encode($day);     
}

my return headers:

Answer 1

The reason is due to CSRF validation. Once i turn off the csrf validation at my site, the problems solved. But now i have another issue that the data i post to my site is always null.

Answer 2

It looks like the server is not processing the request due to client error - something like wrong request syntax etc.. It's exactly the same situation when you put wrong webpage address in your browser and see typical "400 Bad Request" message.

I am not an expert, but aybe, because there is no
func _on_HTTPRequest_request_completed ?

Thank you for reading my question. I did have write the function onHTTPRequestrequestcompleted. And $HTTPRequest.request(url) on the same url did works for me.
