本文介绍了带有“ Cookie”的HttpURLConnection addRequestProperty导致逗号分隔的Cookie字符串？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我必须从Java代码模拟浏览器的行为。 在将请求发布到服务器之前，我必须在请求上设置两个cookie。 我这样做： HttpURLConnection conn = ... ... conn.addRequestProperty（ Cookie， IDS_SSO_ID = + onething）; conn.addRequestProperty（ Cookie， JSESSIONID = + otherthing）））; ... conn.close（）; 在服务器日志上，我看到 IDS_SSO_ID cookie被检索为 onething，JSESSIONID，这会导致错误。 请注意，我无权访问服务器或服务器的源代码，我只有日志。 如何使用HttpURLConnection设置cookie？ 因此，我创建了一个小示例；如果我使用 addRequestProperty，则会发送不正确的Cookie标头： URL url = new URL（ https：// en0hphl04qcwvf .x.pipedream.net /）; HttpURLConnection conn =（HttpURLConnection）url.openConnection（）; conn.addRequestProperty（ Cookie， JSESSIONID = akarmi123）; conn.addRequestProperty（ Cookie， IDS_SSO_ID = netudd321）; byte [] bytes = StreamUtils.copyToByteArray（conn.getInputStream（））; System.out.println（ response： +新的String（bytes））; conn.disconnect（）; cookie标头值为： JSESSIONID = akarmi123，IDS_SSO_ID = netudd321 如果我使用'setRequestProperty'并手动构造cookie头，则会发送正确的cookie头： conn =（HttpURLConnection）url.openConnection（）; conn.setRequestProperty（ Cookie， JSESSIONID = akarmi123; IDS_SSO_ID = netudd321）; 字节= StreamUtils.copyToByteArray（conn.getInputStream（））; System.out.println（ response： +新的String（bytes））; conn.disconnect（）; cookie标头值为： JSESSIONID = akarmi123; IDS_SSO_ID = netudd321 奇怪的是，网络中的大量资源（以及SO中的资源）推荐了我的第一种方法-多次调用在addRequestProperty（...）上： 如何使用Java在Http Get方法中设置Cookie https://www.codota.com/code/java/methods/java.net.URLConnection/addRequestProperty https://www.programcreek.com/java-api-examples/?class=java.net.HttpURLConnection&method=addRequestProperty http：// w ww.massapi.com/method/ad/addRequestProperty-2.html 但似乎他们错了... 解决方案一种可能性是通过执行以下操作来强制cookie字符串的正确连接： conn.addRequestProperty（ Cookie， JSESSIONID = + otherthing +; IDS_SSO_ID = + onething）; 您所描述的行为在我看来是意外行为。 I have to emulate browser behaviour from Java code.I have to set two cookies on a request before posting it to the server.I do this:HttpURLConnection conn = ......conn.addRequestProperty("Cookie", "IDS_SSO_ID=" + "onething");conn.addRequestProperty("Cookie", "JSESSIONID=" + "otherthing"));...conn.close();On the server logs I see that the 'IDS_SSO_ID' cookie is retrieved as "onething, JSESSIONID", which causes an error.Note that I have no access to the server nor the server's source code, I only have the logs.How should I set cookies using HttpURLConnection?So, I've created a small demonstration; If I use 'addRequestProperty' then an incorrect cookie header is sent:URL url = new URL("https://en0hphl04qcwvf.x.pipedream.net/");HttpURLConnection conn = (HttpURLConnection) url.openConnection();conn.addRequestProperty("Cookie", "JSESSIONID=akarmi123");conn.addRequestProperty("Cookie", "IDS_SSO_ID=netudd321");byte[] bytes = StreamUtils.copyToByteArray(conn.getInputStream());System.out.println("response: " + new String(bytes));conn.disconnect();cookie header value is: JSESSIONID=akarmi123, IDS_SSO_ID=netudd321If I use 'setRequestProperty' and manually construct the cookie header, then a correct cookie header is sent:conn = (HttpURLConnection) url.openConnection();conn.setRequestProperty("Cookie", "JSESSIONID=akarmi123; IDS_SSO_ID=netudd321");bytes = StreamUtils.copyToByteArray(conn.getInputStream());System.out.println("response: " + new String(bytes));conn.disconnect();cookie header value is: JSESSIONID=akarmi123; IDS_SSO_ID=netudd321The strange thing is, that a lot of resources in the web (and here in SO too) recommends my first approach -- multiple calls on addRequestProperty(...):How to set Cookies at Http Get method using Javahttps://www.codota.com/code/java/methods/java.net.URLConnection/addRequestPropertyhttps://www.programcreek.com/java-api-examples/?class=java.net.HttpURLConnection&method=addRequestPropertyhttp://www.massapi.com/method/ad/addRequestProperty-2.htmlBut it seems that they are wrong... 解决方案 A possibility would be to enforce the right concatenation of the cookie strings by doing the following:conn.addRequestProperty("Cookie", "JSESSIONID=" + "otherthing" + ";IDS_SSO_ID=" + "onething");The behavior described by you looks to me as an unintended behavior. 这篇关于带有“ Cookie”的HttpURLConnection addRequestProperty导致逗号分隔的Cookie字符串？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
