jdk 1.8.0_91 中的 Accept-Encoding 标头错误

【问题标题】：Error in Accept-Encoding header in jdk 1.8.0_91jdk 1.8.0_91 中的 Accept-Encoding 标头错误
【发布时间】：2016-12-22 03:44:28
【问题描述】：

我正在拨打POST 电话。该调用在一个系统（比如 system1）上运行，而在另一个系统（比如 system2）上不运行。

我收到以下错误：

标题

我在两个系统上都发送以下标头：Accept-Encoding: gzip, deflate, br

Java 版本 系统1：

java version "1.8.0_51"
Java(TM) SE Runtime Environment (build 1.8.0_51-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.51-b03, mixed mode)

系统2：

openjdk version "1.8.0_91"
OpenJDK Runtime Environment (build 1.8.0_91-8u91-b14-3ubuntu1~16.04.1-b14)
OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode)

我也试过检查抛出错误的源代码（checkMessageHeader方法的检查代码）：

dk8-b91:http://hg.openjdk.java.net/jdk8/jdk8/jdk/file/169451cf0cc5/src/share/classes/sun/net/www/protocol/http/HttpURLConnection.java

jdk8-b51:http://hg.openjdk.java.net/jdk8/jdk8/jdk/file/e865efbc7105/src/share/classes/sun/net/www/protocol/http/HttpURLConnection.java

在这两个文件中，checkMessageHeader 的源代码是相同的。源代码也在检查\n 并在检查某些条件后抛出错误，但前提是\n 存在。我的键或值中没有任何\n。

我无法理解可能是什么问题？或者如何进行？

【问题讨论】：

  • 检查Accept-Encoding的内容，如果可能的话，添加到问题中
  • 我已经在问题中添加了这一点，请参阅下面的共享堆栈跟踪。让我强调一下
  • 尝试删除前导逗号以及所有空格。
  • 我错误地放在这里的前导逗号（现在删除它）。让我删除空格后试试。
  • 我试过去掉空格，还是报错。

标签： java http java-8 httpurlconnection http-accept-encoding


【解决方案1】：

为我的案例找到了解决方案。 ':' 字符造成了问题（至少在我的情况下）。

如果我执行以下操作：

headers.put("授权",Collections.singletonList("Bearer 123"));

没关系。

所以，我认为在这个线程的原始问题中，如果提供了“Accept-Encoding”，而不是将密钥提供为“Accept-Encoding：”，那么可能会起作用。

切！
