Python xmlrpclib 参数传递

Question

我想使用 Python RPC 传递一些数据。我得到了正确的结果，但也得到了一个错误。

xmlrpclib.Fault: :invalid literal for float(): 127.0.0.1">.

我没有更改任何内容，只是突然出现错误。当我尝试使用 PRC api 传递数据时，它看起来像参数问题。但我还是没听懂。

def election_stop():
    time.sleep(5)
    while 1:
        global candidate_ids,candidate_adds,candidate_ports,lessthan
        if take_over==True and lessthan<=devices_attached:
        index_=candidate_ids.index(max(candidate_ids))
        add_s=candidate_adds[index_]
        port_s=candidate_ports[index_]
        print candidate_adds
        print "[Gateway]"+str(add_s)+str(port_s)+"win"
    try:
        proxy = xmlrpclib.ServerProxy("http://"+add_s+":"+str(port_s)+"/")
        ret = proxy.elec_recv("WIN",str(port_s),str(add_s),"you win pls takeover")
        #ret = proxy.elec_recv("LEADER",candidate_ports[0:lessthan],candidate_adds[0:lessthan],candidate_ids[0:lessthan])
        ret = proxy.elec_recv("LEADER",candidate_ports[0:lessthan],candidate_adds[0:lessthan],candidate_ids[0:lessthan])
        break
    except socket_error,exceptions.ValueError:
        print socket_error
        continue
    return "stop"

您将参数 "127.0.0.1" 传递给服务器上的函数，该函数需要 float 类型的参数。
