Dil*_*ill 2 html python browser
有没有办法从本地HTML页面调用程序(Python脚本)?我在该页面上有一个YUI颜色选择器,需要通过rs232将其值发送到微控制器.(除了选择器之外还有其他东西,所以我无法编写应用程序而不是HTML页面.)
稍后,这将迁移到服务器,但我现在需要一个快速简便的解决方案.
谢谢.
我现在看到Daff提到了简单的HTTP服务器,但我就如何解决你的问题(使用BaseHTTPServer)做了一个例子:
import BaseHTTPServer
HOST_NAME = 'localhost'
PORT_NUMBER = 1337
class MyHandler(BaseHTTPServer.BaseHTTPRequestHandler):
def do_GET(s):
s.send_response(200)
s.send_header('Content-Type', 'text/html')
s.end_headers()
# Get parameters in query.
params = {}
index = s.path.rfind('?')
if index >= 0:
parts = s.path[index + 1:].split('&')
for p in parts:
try:
a, b = p.split('=', 2)
params[a] = b
except:
params[p] = ''
# !!!
# Check if there is a color parameter and send to controller...
if 'color' in params:
print 'Send something to controller...'
# !!!
s.wfile.write('<pre>%s</pre>' % params)
if __name__ == '__main__':
server_class = BaseHTTPServer.HTTPServer
httpd = server_class((HOST_NAME, PORT_NUMBER), MyHandler)
try:
httpd.serve_forever()
except KeyboardInterrupt:
pass
httpd.server_close()
