java - 这段代码有什么问题吗？ (java)(错误: cannot find symbol method getValue() )

Question

周围有**的地方会抛出找不到符号方法getValue()错误。

顺便说一下，该代码是检查我的世界帐户名称有效性的程序的一部分；是否可用。

 public String connectToMigrate() {
  try {
  Connection.Response response = 
    Jsoup.connect("https://account.mojang.com/migrate").execute();
  Document doc = response.parse();
  Element authToken = doc.select("input[name^=authenticityToken]").get(0);
  Map cookies = response.cookies();
  Connection connection = 
    Jsoup.connect("https://account.mojang.com/migrate/check")
    .data("authenticityToken", authToken.val())
    .data("mcusername", this.username)
    .data("password", this.password)
    .method(Connection.Method.POST)
    .followRedirects(true);
  connection.timeout(10000);
  for (Object cookie : cookies.entrySet()) {
      connection.cookie((String) **cookie.getValue**(), (String)  **cookie.getKey**());
  }
  Connection.Response postResponse = connection.execute();
  if (postResponse.body().toLowerCase().contains("invalid username"))
    return "error";
  if (postResponse.body().toLowerCase().contains("already been migrated"))
    return "error";
  if (postResponse.body().toLowerCase().contains("locked out"))
    return "error";
  if (postResponse.body().toLowerCase().contains("bought minecraft"))
    return "error";
  if (postResponse.body().toLowerCase().contains("too many failed attempts")) {
    getNewProxy();
    return "try again";
  }
  if (postResponse.body().toLowerCase().contains("error")) {
    return "try again";
  }

  Map cookies2 = postResponse.cookies();
  Connection connection2 = 
    Jsoup.connect("https://account.mojang.com/migrate/chooseEmail");
  for (Object cookie : cookies2.entrySet()) {
      connection2.cookie((String) **cookie.getValue()**, (String) **cookie.getKey()**);
  }
  connection2.timeout(10000);
  Connection.Response postResponse2 = connection2.execute();
  String s = postResponse2.body().toLowerCase();
  s = s.split("i want to use <strong>")[1];
  s = s.split("</strong>")[0];
  String email = s;
  return email; } catch (Exception e) {
}return "try again";
}

cookie 是一个不包含 getValue() 方法的对象。您需要在调用 getValue() 之前将其转换为正确的类型。
