STF之SSO认证

集成了公司的SSO认证，一直工作正常，临时断电，重启PC后。服务正常启动，但服务时走认证流程时提示——Failed to obtain access token，搜索对应的问题，找到InternalOAuthError: Failed to obtain access token

InternalOAuthError: Failed to obtain access token

看起来是相同的问题，直接采用require('https').globalAgent.options.rejectUnauthorized = false;问题依然复现。

在node_modules/passport-oauth2/lib/strategy.js文件中添加debug信息，重启服务后提示——getaddrinfo ENOTFOUND，看起来是无法找到SSO服务器。从STF所在的机器ping此地址（断电重启的原因？）尝试先在/etc/hosts中添加解析地址。搞定~

Failed to obtain access in======== token:  { Error: getaddrinfo ENOTFOUND sso.test-sso.com sso.test-sso.com:443
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:67:26)
  errno: 'ENOTFOUND',
  code: 'ENOTFOUND',
  syscall: 'getaddrinfo',
  hostname: 'sso.test-sso.com',
  host: 'sso.test-sso.com',
