java - 在 Java 中处理包含等于 ("=") 的 Cookie

Question

我正在通过以下方式发送请求。

    HttpClient httpClient=new DefaultHttpClient();
    CookieStore cookieStore=new BasicCookieStore();
    HttpContext httpContext=new BasicHttpContext();
    httpContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);
    httpClient.execute(httppost,httpContext);

我在 java 端的 auth cookie 是这样写的。

(注意\075)

服务器端是这样的

XNlciI6WzU2Mjk0OTk1MzQyMTMxMjAsMCwiejJYUXpQQVhBQ0lQVkdCQU5FMkRtdSIsMTM3MzM0OTIyNiwxMzczMzQ5MjI2XX0

当我使用 python 请求时，显示的 cookie 如下。

XNlciI6WzU2Mjk0OTk1MzQyMTMxMjAsMCwiclYzYW1FakRHc0dhampDcnhoMlBIVyIsMTM3MzM0OTEzNiwxMzczMzQ5MTM2XX0=|1373349137|e8900c8bfd2972ca4115ef1946b14cdf15

HttpClient 似乎忽略了 | 之后的位(日期代码和东西)。我错过了什么吗？我也尝试了所有 cookie 策略，但没有任何效果。

好的，我通过以下方式解决了它。在我回答一些事实之前。

1. Cookie 键值对由“=”分隔。
2. 必须对其中包含“=”的 Cookie 进行转义(“=”部分)。
3. 包含“=”的cookie需要指定为Version1 cookie
4. 此类 cookie 必须用双引号括起来。

这是我的整个发布方法。

    public String doUrlPost(final String connurl,final JSONObject obj) throws IOException{
              CookieManager cookieManager = new CookieManager();
      CookieHandler.setDefault(cookieManager);

      URL url=new URL(connurl);
       HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
         urlConnection.setDoOutput(true);
         urlConnection.setRequestMethod("POST");
         urlConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); 
                 //sets the cookie to version 1
         urlConnection.setRequestProperty("Cookie2","$Version=1");

         List<HttpCookie> lst=((CookieManager)CookieHandler.getDefault()).getCookieStore().getCookies();
         for(HttpCookie cookie:lst){

             if(cookie.getName().equals("auth")){
             //double quote your cookie
              urlConnection.setRequestProperty("Cookie","auth=\""+cookie.getValue()+"\"");
             }
         }
         urlConnection.setUseCaches(false);      

         List<NameValuePair> nameValuePairs = getData(obj);

         OutputStream out = urlConnection.getOutputStream();
         BufferedWriter writer = new BufferedWriter(
                    new OutputStreamWriter(out, "UTF-8"));           
         writer.write(getQuery(nameValuePairs));
         writer.close();

        InputStream in = new BufferedInputStream(urlConnection.getInputStream());
        BufferedReader rd=new BufferedReader(new InputStreamReader(in));
        String line="";
        String content="";
        while((line=rd.readLine())!=null){
            content+=line;
        }
        rd.close();
        finalcontent=content;
        urlConnection.disconnect(); 
        return finalcontent;
} 

获取查询方法

    private String getQuery(List<NameValuePair> params) throws UnsupportedEncodingException
{
    StringBuilder result = new StringBuilder();
    boolean first = true;

    for (NameValuePair pair : params)
    {
        if (first)
            first = false;
        else
            result.append("&");

        result.append(URLEncoder.encode(pair.getName(), "UTF-8"));
        result.append("=");
        result.append(URLEncoder.encode(pair.getValue(), "UTF-8"));
    }

    return result.toString();
}
