jsoup发布和cookie
|
我正在尝试使用jsoup登录网站，然后抓取信息，我遇到了一个问题，我可以成功登录并从index.php创建文档，但无法在网站上获取其他页面。我知道发布后需要设置一个cookie，然后在尝试打开网站上的另一个页面时加载它。但是我该怎么做呢？以下代码可让我登录并获取index.php
Document doc = Jsoup.connect(\"http://www.example.com/login.php\")
.data(\"username\", \"myUsername\",
\"password\", \"myPassword\")
.post();

Connection.Response res = Jsoup.connect(\"http://www.example.com/login.php\") .data(\"username\", \"myUsername\", \"password\", \"myPassword\") .method(Method.POST) .execute(); Document doc = res.parse(); String sessionId = res.cookie(\"SESSIONID\"); // you will need to check what the right cookie name isDocument doc2 = Jsoup.connect(\"http://www.example.com/otherPage\") .cookie(\"SESSIONID\", sessionId) .get();诧不达
//This will get you the response. Response res = Jsoup .connect(\"loginPageUrl\") .data(\"loginField\", \"login@login.com\", \"passField\", \"pass1234\") .method(Method.POST) .execute(); //This will get you cookies Map<String, String> loginCookies = res.cookies(); //And this is the easiest way I\'ve found to remain in session Document doc = Jsoup.connect(\"urlYouNeedToBeLoggedInToAccess\") .cookies(loginCookies) .get();亨尖玛次酥
在将其更改为以下内容之前，我遇到了麻烦：现在它可以完美地工作了。社攻取墟槽
import org.jsoup.Connection; Connection.Response res = null; try { res = Jsoup .connect(\"http://www.example.com/login.php\") .data(\"username\", \"your login id\", \"password\", \"your password\") .method(Connection.Method.POST) .execute(); } catch (IOException e) { e.printStackTrace(); }向另一个页面发出请求。try { Document doc = Jsoup.connect(\"your-second-page-link\").cookies(cookies).get(); } catch(Exception e){ e.printStackTrace(); }
