Question

我正在跟随Miguel先生关于烧瓶的书。我被困在登录功能中，我向用户发送电子邮件确认，然后点击链接后会要求用户登录但登录后请求.args.get（'next'）变量为空，因此永远不会执行确认功能。我怀疑这是由于before_app_request引起的。我对烧瓶很新，我花了两天时间试图解决这个问题。 Miguels版本工作正常，我似乎被诅咒。其他人的观点确实需要。谢谢你的阅读。

我没有遵循的一件事是我们不需要在表单中设置动作变量，因为本书使用了wtf快速表单选项我从未注意到它

shrinkImageFunction() {
 echo
 echo Compressing $1 . . .

 curl --user api: https://tinypng.com/developers \
      --data-binary @$1 \
      -o .$1-json \
      -s \
      https://api.tinify.com/shrink

 cat .$1-json | jq -r '.output.url' > .$1-url

 url=$(cat .$1-url)

 if [ -z "$url" ]; then
      echo Something went wrong
      return
 fi

 echo Downloading $url . . .

 echo
 curl -o compressed-$1 $url
 echo

 rm .$1-json
 rm .$1-url
}

# alias for using tinypng
alias shrinkImage=shrinkImageFunction
