如何使用cookieManager在httpUrlConnection中处理cookie

问题描述

我有一个返回多个Cookie的服务器请求，例如：

这是我如何存储这些cookie到cookieManager：

  HttpURLConnection connection = ...; 
 static java.net.CookieManager msCookieManager = new java.net.CookieManager（）; 
 msCookieManager.put（COOKIES_URI，connection.getHeaderFields（））; 
  

这是我将这些Cookie添加到下一个连接的方式：

  connection.setRequestProperty（Cookie，
 msCookieManager.getCookieStore（）。get（COOKIES_URI）.toString（））; 
  

这是从cookieManager获取cookie的正确方法吗？
相当肯定有更好的一个...

解决方案

好吧，正确的方法就是这样： p>

从响应标头获取Cookie并将其加载到cookieManager中：

 code> static final String COOKIES_HEADER =Set-Cookie; 
 HttpURLConnection connection = ...; 
 static java.net.CookieManager msCookieManager = new java.net.CookieManager（）; 
 
 Map< String，List< String>> headerFields = connection.getHeaderFields（）; 
 List< String> cookiesHeader = headerFields.get（COOKIES_HEADER）; 
 
 if（cookiesHeader！= null）{
 for（String cookie：cookiesHeader）{
 msCookieManager.getCookieStore（）。add（null，HttpCookie.parse （0））; 
} 
} 
  

从CookieManager获取Cookie，连接：

  if（msCookieManager.getCookieStore（）。getCookies（）。size（）> 0）{ 
 //加入Cookies时，根据需要使用'，'或';'。大多数服务器使用';'
 connection.setRequestProperty（Cookie，
 TextUtils.join（;，msCookieManager.getCookieStore（）。getCookies（）））; 
} 
  

I have a server request that returns multiple cookies, like that:

This is how I'm storing these cookies to the cookieManager:

HttpURLConnection connection = ... ;
static java.net.CookieManager msCookieManager = new java.net.CookieManager();
msCookieManager.put(COOKIES_URI, connection.getHeaderFields());

This is how I'm adding these cookies to the next connection:

connection.setRequestProperty("Cookie",
  msCookieManager.getCookieStore().get(COOKIES_URI).toString());

Is it the right way to get the cookies from the cookieManager?,I'm quite sure there is a better one...

解决方案

Ok, the right way to do it is just like that:

Get Cookies from response header and load them into cookieManager:

static final String COOKIES_HEADER = "Set-Cookie";
HttpURLConnection connection = ... ;
static java.net.CookieManager msCookieManager = new java.net.CookieManager();

Map<String, List<String>> headerFields = connection.getHeaderFields();
List<String> cookiesHeader = headerFields.get(COOKIES_HEADER);

if (cookiesHeader != null) {
    for (String cookie : cookiesHeader) {
        msCookieManager.getCookieStore().add(null,HttpCookie.parse(cookie).get(0));
    }
}

Get Cookies from cookieManager and load them into connection:

if (msCookieManager.getCookieStore().getCookies().size() > 0) {
    // While joining the Cookies, use ',' or ';' as needed. Most of the servers are using ';'
    connection.setRequestProperty("Cookie",
    TextUtils.join(";",  msCookieManager.getCookieStore().getCookies()));
}
