Python给出了一个来自Thingspeak的HTTP错误500

Question

这是我的密码

import os
import glob
import time
import sys
import datetime
import urllib2

baseURL = "https://api.thingspeak.com/update?api_key=DCL2IZ1REQT5GUSM"
os.system('modprobe w1-gpio')
os.system('modprobe w1-therm')
base_dir = 'sys/bus/w1/devices/'

#Temp1 temperature device location
temp1_file = '/sys/bus/w1/devices/28-0000087787c4/w1_slave'

#Temp2 temperature Device Location
temp2_file = '/sys/bus/w1/devices/28-000008762fa3/w1_slave'

#Determine Temp1 Temperature
def read_rawtemp_temp1():
    y = open(temp1_file,'r')
    lines = y.readlines()
    y.close
    return lines

def read_temp_temp1():
    lines = read_rawtemp_temp1()
    while lines[0].strip()[-3:] !='YES':
        time.sleep(0.2)
        lines = read_rawtemp_temp1()
    equals_pos = lines[1].find('t=')

    if equals_pos !=-1:
        temp_string = lines[1][equals_pos+2:]
        temp_temp1 = ((float(temp_string)/1000.0)*1.8)-32
        return temp_temp1

#Determine Temp2 Temperature

def read_rawtemp_temp2():
    x = open(temp2_file,'r')
    lines = x.readlines()
    x.close
    return lines

def read_temp_temp2():
    lines = read_rawtemp_temp2()
    while lines[0].strip()[-3:] !='YES':
        time.sleep(0.2)
        lines = read_rawtemp_temp1()

    equals_pos = lines[1].find('t=')
    if equals_pos !=-1:
        temp_string = lines[1][equals_pos+2:]
        temp_temp2 = float(temp_string)/1000.0
        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:
    pass 

#Time to next loop
time.sleep(600)

下面是一个错误，它将在几个小时后停止脚本的运行。在

Traceback (most recent call last):
File "tempdatalog.py", line 137, in <module>
j = urllib2.urlopen(baseURL + "&field1=%s" % (temp1_tempin) +
"&field2=%s" % (temp2_tempin))

这是想让它忽略错误，但没用。任何建议，将是伟大的，这只是一个开始的监测医疗系统在移动。在

看看您的stacktrace，您似乎在try/except子句中换行了。在

File "tempdatalog.py", line 137, in j = urllib2.urlopen(baseURL + "&field1=%s" % (temp1_tempin) + "&field2=%s" % (temp2_tempin))

此版本至少捕获异常：

#Open Thingspeak channel and assign fields to temperatures
try:
    j = urllib2.urlopen(baseURL + "&field1=%s" % (temp1_tempin) + "&field2=%s" % (temp2_tempin))
    search_response = urllib2.urlopen(search_request)
except urllib2.HTTPError:
    pass 

这仍然不能解释为什么错误首先出现。我猜是一种利率限制
