從HttpClient的轉換3至HttpClient的4（Cookie政策）

Question

以前，我在httpclient3

// To prevent cookie warnings. 
httpClient.getParams().setParameter("http.protocol.single-cookie-header", true); 
httpClient.getParams().setCookiePolicy(org.apache.commons.httpclient.cookie.CookiePolicy.BROWSER_COMPATIBILITY); 

下面的代碼我想知道，什麼是httpclient4等價代碼，因爲我在第二收到錯誤線。

// To prevent cookie warnings. 
httpClient.getParams().setParameter("http.protocol.single-cookie-header", true); 
// ??? compilation error in this line. 
// org.apache.commons.httpclient cannot be resolved to a variable 
httpClient.getParams().setCookiePolicy(org.apache.commons.httpclient.cookie.CookiePolicy.BROWSER_COMPATIBILITY);

因此，嘗試這條線：

httpClient.getParams().setParameter(ClientPNames.COOKIE_POLICY, CookiePolicy.BROWSER_COMPATIBILITY); 

Answer 2

由於4.3版getParams()，ClientPNames和CookiePolicy都已過時。爲了達到同樣的效果，你必須這樣做：

final RequestConfig params = RequestConfig 
     .custom() 
     .setCookieSpec(CookieSpecs.IGNORE_COOKIES) 
     .build(); 

httpPost.setConfig(params);
