这里是我的代码Python从Thingspeak给人一种HTTP错误500 intermiittantly
import os

baseURL = "https://api.thingspeak.com/update?api_key=DCL2IZ1REQT5GUSM"

def read_rawtemp_temp1():

y.close
return lines

while lines[0].strip()[-3:] !='YES':

return temp_temp2
while True: #Loop
#Send Temp1 Temperature to Thingspeak
temp1_tempin = read_temp_temp1()
#Send temp2 temperature to Thingspeak
temp2_tempin = read_temp_temp2()
#Pull results together
values = [datetime.datetime.now(), temp1_tempin, temp2_tempin]
#Open Thingspeak channel and assign fields to temperatures
j = urllib2.urlopen(baseURL + "&field1=%s" % (temp1_tempin) + "&field2=%s" % (temp2_tempin))
try:
search_response = urllib2.urlopen(search_request)
except urllib2.HTTPError:

#Time to next loop
time.sleep(600)
以下是错误，这将在几个小时后，停止运行该脚本。
Traceback (most recent call last):

raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
urllib2.HTTPError: HTTP Error 500: Internal Server Error
我说：
try:
search_response = urllib2.urlopen(search_request)
except urllib2.HTTPError:
pass
这设法得到它越过错误，但没有奏效。任何建议都会很棒，这只是移动设备中监测医疗系统的开始。
请编辑您的问题以正确格式化代码，它会更容易阅读。请参阅[这里]（https://meta.stackexchange.com/help/formatting）了解有关帖子格式的信息。 –
'x.close' does _not_关闭文件'x'。 'x.close（）'确实。 – DyZ
您没有在'try'块中包含'j = urllib2.urlopen（...）'。根据你的回溯信息，'HTTPError'是由该行引起的。 –
