Hi there,
I'm trying to get AJAX POST to work properly using a local web.py
server. It seems that I can create a successful POST using the first
AJAX call. The second call fails, and then every subsequent call
works! If I stop the server and restart, I get the same failure on the
second call. I'm thinking this is a problem with my python code, but
if not, could someone out there please correct me?
Try it for yourself and you'll see what I mean. Also, you'll need to
test this in Firefox and you might need to change the port to suit
your configuration.
Here's my HTML file:
******************************************************************
<html>
<head>
<title>Firefox to Python and back...</title></head>
<script>
function alertContents() {
if (http_request.readyState == 4) {
if (http_request.status == 200) {
var string = http_request.responseText;
alert(string);
} else {
alert('There was a problem with the request.');
}
}
POSTDATA = "";
}
var testvalue1 = '5';
var testvalue2 = 'Hello World!';
var POSTDATA = 'test1=' + escape(testvalue1) + '&test2=' +
escape(testvalue2);
function makeRequest(url, parameters) {
try {
netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead");
} catch (e) {
alert("Permission UniversalBrowserRead denied.");
}
http_request = false;
http_request = new XMLHttpRequest();
if (!http_request) {
alert('Cannot create XMLHTTP instance');
return false;
}
http_request.open('POST', url, true);
http_request.setRequestHeader('content-type', 'text/plain');
http_request.onreadystatechange = alertContents;
http_request.send(POSTDATA);
}
</script>
<body>
<a href="#" onClick='makeRequest("http://127.0.0.1:8080/
view","");'>makeRequest</a>
</body>
</html>
******************************************************************
Here's my PYTHON file: app.py
******************************************************************
import web, os, sys
#load urls and matching classes
urls = (
'/view', 'view',
'/test', 'test',
'/quit','quit'
)
class view:
def POST(self):
print('Hello Test!')
web.internalerror = web.debugerror
if __name__ == "__main__":
os.spawnv(os.P_NOWAIT,'runxulapp.bat',['',''])
web.run(urls, globals())
******************************************************************
TIA.
