Cookie name \"{0}\" is a reserved token

[weijie0]

对于name以$开头的cookie会报错，这个和tomcat稍有区别 原因如下：

在servlet里，cookie的规范如下 if (!isToken(name) || name.equalsIgnoreCase("Comment") || // rfc2019 name.equalsIgnoreCase("Discard") || // 2019++ name.equalsIgnoreCase("Domain") || name.equalsIgnoreCase("Expires") || // (old cookies) name.equalsIgnoreCase("Max-Age") || // rfc2019 name.equalsIgnoreCase("Path") || name.equalsIgnoreCase("Secure") || name.equalsIgnoreCase("Version") || name.startsWith("$")) { 但是在tomcat里，cookie的实现并没有按照servlet的逻辑去做，而是自己实现的，仅仅做了长度验证，如下： public Cookie(String name, String value) { validation.validate(name); this.name = name; this.value = value; } class CookieNameValidator { private static final String LSTRING_FILE = "javax.servlet.http.LocalStrings"; protected static final ResourceBundle lStrings = ResourceBundle.getBundle("javax.servlet.http.LocalStrings"); protected final BitSet allowed = new BitSet(128);

protected CookieNameValidator(String separators) {
    this.allowed.set(32, 127);

    for(int i = 0; i < separators.length(); ++i) {
        char ch = separators.charAt(i);
        this.allowed.clear(ch);
    }

}

void validate(String name) {
    if (name != null && name.length() != 0) {
        if (!this.isToken(name)) {
            String errMsg = lStrings.getString("err.cookie_name_is_token");
            throw new IllegalArgumentException(MessageFormat.format(errMsg, name));
        }
    } else {
        throw new IllegalArgumentException(lStrings.getString("err.cookie_name_blank"));
    }
}

private boolean isToken(String possibleToken) {
    int len = possibleToken.length();

    for(int i = 0; i < len; ++i) {
        char c = possibleToken.charAt(i);
        if (!this.allowed.get(c)) {
            return false;
        }
    }

    return true;
}

}

这块没注意， 你要是知道怎么改，或者愿意的话， 可以提pull request改下。 我给合并上去。 我晚会我看下咋改。

已解决, 把tomcat的Cookie拿来覆盖了. https://github.com/wangzihaogithub/spring-boot-protocol/commit/cc7aaf83f260e5ffcac9806959f7fc5529a85188
