I am using the following code taken from the godot docs on how to make a http call using godot.
func send_data_to_server(url, data):
var err = 0
var http = HTTPClient.new() # Create the Client
err = http.connect_to_host(url, 80) # Connect to host/port
assert(err == OK) # Make sure connection was OK
# Wait until resolved and connected
while http.get_status() == HTTPClient.STATUS_CONNECTING or http.get_status() == HTTPClient.STATUS_RESOLVING:
http.poll()
print("Connecting..")
OS.delay_msec(500)
assert(http.get_status() == HTTPClient.STATUS_CONNECTED) # Could not connect
# Some headers
var headers = [
"User-Agent: Pirulo/1.0 (Godot)",
"Accept: */*",
"Content-Type: application/x-www-form-urlencoded"
]
err = http.request(HTTPClient.METHOD_POST, "/Post", headers, data) # Request a page from the site (this one was chunked..)
assert(err == OK) # Make sure all is OK
while http.get_status() == HTTPClient.STATUS_REQUESTING:
# Keep polling until the request is going on
http.poll()
print("Requesting..")
OS.delay_msec(500)
assert(http.get_status() == HTTPClient.STATUS_BODY or http.get_status() == HTTPClient.STATUS_CONNECTED) # Make sure request finished well.
print("response? ", http.has_response()) # Site might not have a response.
if http.has_response():
# If there is a response..
headers = http.get_response_headers_as_dictionary() # Get response headers
print("code: ", http.get_response_code()) # Show response code
print("**headers:\\n", headers) # Show headers
# Getting the HTTP Body
if http.is_response_chunked():
# Does it use chunks?
print("Response is Chunked!")
else:
# Or just plain Content-Length
var bl = http.get_response_body_length()
print("Response Length: ",bl)
# This method works for both anyway
var rb = PoolByteArray() # Array that will hold the data
while http.get_status() == HTTPClient.STATUS_BODY:
# While there is body left to be read
http.poll()
var chunk = http.read_response_body_chunk() # Get a chunk
if chunk.size() == 0:
# Got nothing, wait for buffers to fill a bit
OS.delay_usec(1000)
else:
rb = rb + chunk # Append to read buffer
# Done!
print("bytes got: ", rb.size())
var text = rb.get_string_from_ascii()
print("Text: ", text)
However, I keep getting the following error:
‘HTTPClient polled multiple times in one frame, but request cannot progress more than once per frame on the HTML5 platform.’
Is anybody able to point out where I am going wrong?
