设置:我试图用Python 3处理请求创建一个简单的D3 js演示。按照下面的步骤,我希望看到我用d3方法点击我的html页面时出现错误或某种HTML。相反,我收到一个空白页。
from http.server import BaseHTTPRequestHandler, HTTPServer
import os
class HTTPRequestHandler(BaseHTTPRequestHandler):
#handle GET command
def do_GET(self):
rootdir = r'C:\Current_Working_Directory' #file location
try:
if self.path.endswith('.json'):
f = open(rootdir + self.path, 'rb') #open requested file
#send code 200 response
self.send_response(200)
#send header first
self.send_header('Content-type','applicaon/json')
self.end_headers()
#send file content to client
self.wfile.write(f.read())
f.close()
return
except IOError:
self.send_error(404, 'file not found')
def run():
print('http server is starting...')
#ip and port of server
server_address = ('127.0.0.1', 80)
httpd = HTTPServer(server_address, HTTPRequestHandler)
print('http server is running...')
httpd.serve_forever()
if __name__ == '__main__':
run()
