Please I am having a problem modifying wsgi example. The original example is as follows:
import cgi
form = b'''
<html>
<head>
<title>Hello User!</title>
</head>
<body>
<form method="post">
<label>Hello</label>
<input type="text" name="name">
<input type="submit" value="Go">
</form>
</body>
</html>
'''
def app(environ, start_response):
html = form
if environ['REQUEST_METHOD'] == 'POST':
post_env = environ.copy()
post_env['QUERY_STRING'] = ''
post = cgi.FieldStorage(
fp=environ['wsgi.input'],
environ=post_env,
keep_blank_values=True
)
html = b'Hello, ' + post['name'].value + '!'
start_response('200 OK', [('Content-Type', 'text/html')])
return [html]
if __name__ == '__main__':
try:
from wsgiref.simple_server import make_server
httpd = make_server('', 8080, app)
print('Serving on port 8080...')
httpd.serve_forever()
except KeyboardInterrupt:
print('Goodbye.')I am trying to replace the outputted html with javascript code from a library for rendering open street maps like this:form = b'''
<html>
<title>OpenLayers Simplest Example</title>
<div id="demoMap" style="height:250px"></div>
<script src="OpenLayers.js"></script>
<script>
map = new OpenLayers.Map("demoMap");
map.addLayer(new OpenLayers.Layer.OSM());
map.zoomToMaxExtent();
markers = new OpenLayers.Layer.Markers( "Markers" );
markers.id = "Markers";
map.addLayer(markers);
var coordinates = [];
map.events.register("click", map, function(e) {
//var position = this.events.getMousePosition(e);
var toProjection = new OpenLayers.Projection("EPSG:4326");
var position = map.getLonLatFromPixel(e.xy);
var position_t = map.getLonLatFromPixel(e.xy).transform(map.getProjectionObject(), toProjection);
coordinates.push(position_t);
alert(position_t);
var size = new OpenLayers.Size(21,25);
var offset = new OpenLayers.Pixel(-(size.w/2), -size.h);
var icon = new OpenLayers.Icon('images/mark.png', size, offset);
var markerslayer = map.getLayer('Markers');
markerslayer.addMarker(new OpenLayers.Marker(position,icon));
});
$( '#coord_id' ).val( JSON.stringify(coordinates) );
</script>
<form method="POST" action="" class="">
<input type="hidden" name="coord" id="coord_id" value="" />
<input type="submit" name="commit" value="Go" class="float" />
</form>
</html>When I run the simple server I get a blank page. On trouble-shooting using the browser's view page source function, I discovered that the javascript file is not being loaded. I don't know what to do to get it to load (and for the other code between the second set of script tags to work) or if it's even possible to run javascript in such a manner.Any pointers to the resolution of this problem would be greatly appreciated.
