城市输入错误时pyowm模块错误

  • 772

有问题。写了代码。一切正常。但是，如果您输入的不是城市，而是任何单词，则脚本会因错误而崩溃。

from pyowm import OWM
from pyowm.utils.config import get_default_config
config_dict = get_default_config()
config_dict['language'] = 'ru'  # your language here
owm = OWM('api-key')  # You MUST provide a valid API key

place = input("Введи Город/страну: ")
mgr = owm.weather_manager()
observation = mgr.weather_at_place(place)
w = observation.weather
temp = w.temperature('celsius')["temp"]

print("В городе " + place + " Сейчас " + str(w.detailed_status))
print("Температура: " + str(temp))

抛出错误：

Traceback (most recent call last):
  File "C:\python\weather.py", line 18, in <module>
    observation = mgr.weather_at_place(place)
  File "C:\Users\x\AppData\Local\Programs\Python\Python38-32\lib\site-packages\pyowm\weatherapi25\weather_manager.py", line 53, in weather_at_place
    _, json_data = self.http_client.get_json(OBSERVATION_URI, params=params)
  File "C:\Users\x\AppData\Local\Programs\Python\Python38-32\lib\site-packages\pyowm\commons\http_client.py", line 143, in get_json
    HttpClient.check_status_code(resp.status_code, resp.text)
  File "C:\Users\x\AppData\Local\Programs\Python\Python38-32\lib\site-packages\pyowm\commons\http_client.py", line 288, in check_status_code
    raise exceptions.NotFoundError('Unable to find the resource')
pyowm.commons.exceptions.NotFoundError: Unable to find the resource

当然，您可以尝试检查所有缩写词，当且仅当它们合适时，才抛出请求，但这仍然不是这种情况。根据文档，我发现当请求“weather_at_place”时，会返回“Observation”（我对数据的理解）或“None”（如果现在没有数据）。在其他情况下，会引发数据解析器错误（据我了解）：ParseResponseException when OWM Weather API response' data cannot be parsed

那么问题来了，如何不让脚本崩溃，并且在调用解析器错误时，脚本写了类似“错误城市”之类的东西？

    只需捕获异常并处理：

    from pyowm import OWM
from pyowm.utils.config import get_default_config
from pyowm.commons.exceptions import NotFoundError

config_dict = get_default_config()
config_dict['language'] = 'ru'  # your language here
owm = OWM('api-key')  # You MUST provide a valid API key

place = input("Введи Город/страну: ")
mgr = owm.weather_manager()

try:
    observation = mgr.weather_at_place(place)
    w = observation.weather
    temp = w.temperature('celsius')["temp"]
    
    print(f"В городе {place} сейчас {w.detailed_status}")
    print(f"Температура: {temp}")

except NotFoundError:
    print(f'Не найдено место: {place}')
