我很难尝试让基于python的网络服务器工作。
我想进行基本身份验证(发送401标头)并对用户列表进行身份验证。使用“WWW-Authorize”标头发送401响应没有问题,我可以验证用户响应(base64编码的用户名和密码),但是,成功验证后登录框会不断弹出。
import SimpleHTTPServer
import SocketServer
from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer
class Handler(BaseHTTPRequestHandler):
''' Main class to present webpages and authentication. '''
def do_HEAD(self):
print "send header"
self.send_response(401)
self.send_header('WWW-Authenticate', 'Basic realm=\"Test\"')
self.send_header('Content-type', 'text/html')
self.end_headers()
def do_GET(self):
''' Present frontpage with user authentication. '''
self.do_HEAD()
if self.headers.getheader('Authorization') == None:
self.wfile.write('no auth header received')
pass
elif self.headers.getheader('Authorization') == 'Basic dGVzdDp0ZXN0':
self.wfile.write(self.headers.getheader('Authorization'))
self.wfile.write('authenticated!')
pass
else:
self.wfile.write(self.headers.getheader('Authorization'))
self.wfile.write('not authenticated')
pass
httpd = SocketServer.TCPServer(("", 10001), Handler)
httpd.serve_forever()
if __name__ == '__main__':
main()
首次加载(http:// localhost:10001)登录框弹出,我输入test,test(正确的用户)用户验证确定,但框弹出,如果我点击取消,我到达经过验证的页面......
有人可以帮忙吗?我怀疑这与授权在do_GET下发生的事实有关,每次页面加载时都会触发授权。

import SimpleHTTPServer
import SocketServer
from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer
class Handler(BaseHTTPRequestHandler):
''' Main class to present webpages and authentication. '''
def do_HEAD(self):
print "send header"
self.send_response(200)
self.send_header('Content-type', 'text/html')
self.end_headers()
def do_AUTHHEAD(self):
print "send header"
self.send_response(401)
self.send_header('WWW-Authenticate', 'Basic realm=\"Test\"')
self.send_header('Content-type', 'text/html')
self.end_headers()
def do_GET(self):
''' Present frontpage with user authentication. '''
if self.headers.getheader('Authorization') == None:
self.do_AUTHHEAD()
self.wfile.write('no auth header received')
pass
elif self.headers.getheader('Authorization') == 'Basic dGVzdDp0ZXN0':
self.do_HEAD()
self.wfile.write(self.headers.getheader('Authorization'))
self.wfile.write('authenticated!')
pass
else:
self.do_AUTHHEAD()
self.wfile.write(self.headers.getheader('Authorization'))
self.wfile.write('not authenticated')
pass
httpd = SocketServer.TCPServer(("", 10001), Handler)
httpd.serve_forever()
if __name__ == '__main__':
main()

那是因为你无条件地发送401和WWW-Authenticate
标题作为回应。只有在请求中没有可接受的身份验证凭据时,您才需要执行此操作。如果您对请求感到满意,请发送200(或任何适当的)并且不再请求身份验证。
