关于python批量下载ECWMF数据提示Invalid or missing key or token的解决办法

AXD

利用python批量下载ECWMF数据时会提示如下错误：
Traceback (most recent call last):
  File "E:\axd_scripts\PythonScripts\ecwmf\oz.py", line 15, in <module>
    "target": "output.nc",
  File "D:\python\python3.6.8\lib\site-packages\ecmwfapi\api.py", line 519, in retrieve
    c = APIRequest(self.url, "datasets/%s" % (dataset,), self.email, self.key, self.trace, verbose=self.verbose)
  File "D:\python\python3.6.8\lib\site-packages\ecmwfapi\api.py", line 391, in __init__
    user = self.connection.call("%s/%s" % (self.url, "who-am-i"))
  File "D:\python\python3.6.8\lib\site-packages\ecmwfapi\api.py", line 140, in wrapped
    return func(self, *args, **kwargs)
  File "D:\python\python3.6.8\lib\site-packages\ecmwfapi\api.py", line 340, in call
    raise APIException("ecmwf.API error 1: %s" % (self.last["error"],))
ecmwfapi.api.APIException: 'ecmwf.API error 1: Invalid or missing key or token'

原因是此网址https://api.ecmwf.int/v1/key/下载密码有有效期，过期作废，故提示

Invalid or missing key or token

这是我的新密码提示的截止时间(valid until March 29, 2020, 6:32 a.m.)

所以只需重新点该网址，生成新密码，然后复制到.ecmwfapirc里面即可。
