Question

这是一些有效的bash代码：

$(() => {
   $('#newtask').on('keydown', (e) => {
     if(e.keyCode == 13){
       ???
     }
   });
 });

这是我尝试在JVM 11上运行的Scala 2.13进行类似代码的尝试（非Scala程序员应该通过斜视一下即可轻松阅读）。

COOKIE_FILE=cookies.txt
DOMAIN="http://localhost:9000"

function login {
  URL_LOGIN="$DOMAIN/asfd/asdf"

  rm -f "$COOKIE_FILE"
  curl -s \
    -H "Content-type: application/x-www-form-urlencoded" \
    -c "$COOKIE_FILE" \
    -d "username=asdf" \
    -d "password=asdf" \
    -L "$URL_LOGIN" > /dev/null
  if [ -f "$COOKIE_FILE" ]; then
    GREP="grep -P"
    if [ $OSTYPE == *darwin* ]; then GREP=grep; fi
    COOKIE=`$GREP "\tid\t" "$COOKIE_FILE"`
    if [ -z "$COOKIE" ]; then
      echo "Login failed; check your userid and password"
      exit -2
    else
      echo "Cookie is: $COOKIE"
    fi
  else
    echo "Problem: $COOKIE_FILE does not exist"
    exit -3
  fi
}

trait HTTPLike { def ofFormData(data: immutable.Map[String, String]): HttpRequest.BodyPublisher = { val builder = new StringBuilder data.foreach { entry => if (builder.nonEmpty) builder.append("&") builder.append(URLEncoder.encode(entry._1.toString, StandardCharsets.UTF_8)) builder.append("=") builder.append(URLEncoder.encode(entry._2.toString, StandardCharsets.UTF_8)) } BodyPublishers.ofString(builder.toString) } } trait HTTPLike extends HTTPLike { import java.net.http.HttpClient.Redirect import java.net.http.HttpResponse.BodyHandlers import java.net.http.{HttpClient, HttpRequest, HttpResponse} import java.net.{CookieHandler, URI} import scala.collection.immutable import scala.jdk.OptionConverters._ private val domainStr = "http://localhost:9000" private val uriLogin: URI = URI.create(s"$domainStr/asdf/asdf") CookieHandler.setDefault(new CookieManager) CookieHandler.getDefault.asInstanceOf[CookieManager] .setCookiePolicy(CookiePolicy.ACCEPT_ALL) private val client: HttpClient = HttpClient.newBuilder .cookieHandler(CookieHandler.getDefault) .followRedirects(Redirect.NORMAL) .build private val loginData: Map[String, String] = immutable.Map("username" -> "asdf", "password" -> "asdf") private val requestLogin: HttpRequest = HttpRequest.newBuilder .uri(uriLogin) .header("Content-Type", "application/x-www-form-urlencoded") .POST(ofFormData(loginData)) .build def maybeLoginCookie: Option[String] = { val loginResponse: HttpResponse[String] = client.send(requestLogin, BodyHandlers.ofString) val idCookie: Option[String] = loginResponse.headers.firstValue("id").toScala idCookie } }是从其他地方调用的。

即使我看到身份验证有效，也没有得到Cookie。问题可能出在我如何初始化HTTP客户端的cookie处理方面？
