Question

嘿，我有一点问题。我想在Raspberry Pi 3B（学校项目）上制作一个气象站。

这是日志：

     Logger initialization started Check if directory for storing logs is writeable Directory is writeable Logger initialized 
02-05-18 23:45:41 INFO root DHT22logger execution started

    configurationHandler = ConfigHandler()   File "/home/pi/DHT22-TemperatureLogger/Configurations/ConfigHandler.py", line 17, in __init__
    self.configReader = ConfigReader()   File "/home/pi/DHT22-TemperatureLogger/Configurations/ConfigReader.py", line 20, in __init__
    self.configurations = json.loads(open(configurationFile).read())   File "/usr/lib/python2.7/json/__init__.py", line 339, in loads
    return _default_decoder.decode(s)   File "/usr/lib/python2.7/json/decoder.py", line 364, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())   File "/usr/lib/python2.7/json/decoder.py", line 380, in raw_decode
    obj, end = self.scan_once(s, idx) ValueError: Expecting , delimiter: line 10 column 11 (char 357)

我在配置文件中找不到任何东西：

    {
"mysql":[{
        "host":"localhost",
        "user":"[username]",
        "password":"[password]",
        "database":"[database]"
        }],
"sensors":
        [[{"name":"TEMP"},{"gpio":"4"},{"sensorType":"22"},{"temperatureLowLimit":"0"},{"temperatureHighLimit":"25"},{"temperatureThreshold":"5"},{"humidityLowLimit":"30"},{"humidityHighLimit":"60"},{"humidityThreshold":"10"}],
"mailInfo":[{
        "senderaddress":"[MAIL]@gmail.com",
        "receiveraddress":"[MAIL]@gmail.com",
        "username":"[USER]",
        "password":"[PASSWORD]",
        "subjectmessage":"Info von RasPi WeatherStation",
        "subjectwarning":"Warnung von RasPi WeatherStation"
        }],
"sqlBackupDump":[{
        "backupDumpEnabled":"y",
        "backupDay":"3",
        "backupHour":"17",
        "backupDumpPath":"/home/pi/DHT22-TemperatureLogger/Backups/"
        }],
"weeklyAverages":[{
        "weeklyAverageSendingEnabled":"y",
        "weekDayForSendingAverages":"3",
        "hourOfTheDayForSendingAverages":"16"
        }],
"useFahrenheits":"n",
"mailSendingTimeoutInFullHours":"1",
"adafruitPath":"/home/pi/Adafruit_Python_DHT/examples/AdafruitDHT.py"
}

错误指示的部分是mailInfo背后的冒号。

顺便说一下。我正在使用jjpfin的教程，这是近3年前制作的。 The Tutorial

非常感谢提前。

您的JSON无效，因为您缺少]个字符。替换此行

[[{"name":"TEMP"},{"gpio":"4"},{"sensorType":"22"},{"temperatureLowLimit":"0"},{"temperatureHighLimit":"25"},{"temperatureThreshold":"5"},{"humidityLowLimit":"30"},{"humidityHighLimit":"60"},{"humidityThreshold":"10"}],

用这个

[[{"name":"TEMP"},{"gpio":"4"},{"sensorType":"22"},{"temperatureLowLimit":"0"},{"temperatureHighLimit":"25"},{"temperatureThreshold":"5"},{"humidityLowLimit":"30"},{"humidityHighLimit":"60"},{"humidityThreshold":"10"}]],

未来的有用工具，以及我用来检查问题的工具是JSONlint。

“ValueError：Expecting，delimiter：第10行第11列（char 357）”
