Cookie标头无效：当expires属性为空时，无法解析expires属性 [英] Invalid cookie header : Unable to parse expires attribute when expires attribute is empty

问题描述

在Android应用程序中，当使用 DefaultHttpClient 获取URL内容（执行HttpGet）时，我在日志中收到以下警告：

  W / ResponseProcessCookies（20386）：无效的cookie头：Set-Cookie：NSC_vbue_iuuq = ffff660; expires =; domain = private.false.name; path = isSecure = false。无法解析expires属性：
  

我理解警告，因为 expires 字段不包含有效的日期格式。我理解这可能是因为它是一个会话cookie（不是专家）。 关于Curl上下文中的类似情况的主题

搜索网络我发现主要是

  .setParameter（ClientPNames.COOKIE_POLICY，CookiePolicy.BEST_MATCH 
 

选项可通过正确解析包含逗号的日期来避免警告。

但是，我想避免该日志。 （不是禁用日志）
我相信内部一切都很好，因为I GUESS， cookie.setExpiryDate（）根本没有调用。

您认为我需要对HTTP客户端进行特定配置（我没有设置特定配置），以避免发出警告或支持空过期吗？

谢谢。

解决方案

如果您不介意改变 CookieSpec c $>
$ b

首先，创建一个简单的 CookieSpec ，它将接受 null 和 expires 属性的空值，如下所示：

  class LenientCookieSpec extends BrowserCompatSpec {
 public LenientCookieSpec（）{
 super（）; 
 registerAttribHandler（ClientCookie.EXPIRES_ATTR，new BasicExpiresHandler（DATE_PATTERNS）{
 @Override public void parse（SetCookie cookie，String value）throws MalformedCookieException {
 if（TextUtils.isEmpty（value））{
 //你应该在cookie中设置你想要的任何内容
 cookie.setExpiryDate（null）; 
} else {
 super.parse（cookie，value）; 
} 
} 
}）; 
} 
} 
  

现在您需要注册&在您的HTTP客户端中选择此新的 CookieSpec 。

  DefaultHttpClient client = new DefaultHttpClient（）; 
 client.getCookieSpecs（）。register（lenient，new CookieSpecFactory（）{
 public CookieSpec newInstance（HttpParams params）{
 return new LenientCookieSpec（）; 
} 
}）; 
 HttpClientParams.setCookiePolicy（client.getParams（），lenient）; 
  

这样的东西可以为你工作。

In an android application, when using DefaultHttpClient to get an URL content (executing HttpGet) I receive the following warning in logs:

W/ResponseProcessCookies(20386): Invalid cookie header: "Set-Cookie: NSC_vbue_iuuq=ffff660; expires=; domain=private.false.name; path=/; isSecure=false". Unable to parse expires attribute:

I understand the warning because the expires field does not contain a valid date format. I understand it maybe because it is a 'session cookie' (without being expert). Thread about similar situation in Curl context

Searching the web I found mainly the

.setParameter(ClientPNames.COOKIE_POLICY, CookiePolicy.BEST_MATCH (or other) )

option to avoid warning by parsing correctly dates that contain a comma.

However, I would like to avoid that log. (not by disabling logs) I believe internally all is fine since "I GUESS", cookie.setExpiryDate() is simply not called.

Do you think I need a specific configuration of my HTTP client (I've not set specific configurations) to avoid that warning or to support empty expires?

Thanks.

解决方案

If you do not mind altering the CookieSpec you can supply your own, more lenient, subclass.

First, create a lenient CookieSpec that will accept null and empty values for the expires attribute, like this:

class LenientCookieSpec extends BrowserCompatSpec {
    public LenientCookieSpec() {
        super();
        registerAttribHandler(ClientCookie.EXPIRES_ATTR, new BasicExpiresHandler(DATE_PATTERNS) {
            @Override public void parse(SetCookie cookie, String value) throws MalformedCookieException {
                if (TextUtils.isEmpty(value)) {
                    // You should set whatever you want in cookie
                    cookie.setExpiryDate(null);
                } else {
                    super.parse(cookie, value);
                }
            }
        });
    }
}

Now you need to register & choose this new CookieSpec in your HTTP client.

DefaultHttpClient client = new DefaultHttpClient();
client.getCookieSpecs().register("lenient", new CookieSpecFactory() {
        public CookieSpec newInstance(HttpParams params) {
            return new LenientCookieSpec();
        }
    });
HttpClientParams.setCookiePolicy(client.getParams(), "lenient");

Something "like this" could work for you.
