从httpclient 3转换为httpclient 4（Cookie策略）

Question

以前，我在httpclient3

中有以下代码

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

我想知道，httpclient4中的等效代码是什么，因为我在第二行收到错误。

// 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);

Answer 1

此链接可以帮助您解决问题。

所以试试这一行：

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

Answer 2

由于版本4.3 getParams()，ClientPNames和CookiePolicy都已弃用。为了达到相同的效果，你必须这样做：

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

httpPost.setConfig(params);
