Invalid character (CR or LF) found in method name

今天给服务器传了个http head，刚开始我手动输入是ok的，后来直接从接口文档（.doc）里粘贴过去，发现获取不到数据了，服务器的报错日志显示

11-Apr-2019 11:29:59.184 INFO [http-nio-9092-exec-7] org.apache.coyote.http11.AbstractHttp11Processor.process Error parsing HTTP request headerNote: further occurrences of HTTP header parsing errors will be logged at DEBUG level.java.lang.IllegalArgumentException: Invalid character (CR or LF) found in method nameat org.apache.coyote.http11.AbstractNioInputBuffer.parseRequestLine(AbstractNioInputBuffer.java:228)at org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1009)at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:672)at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1500)at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.run(NioEndpoint.java:1456)at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149)at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624)at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61)at java.lang.Thread.run(Thread.java:748)

java.lang.IllegalArgumentException: Invalid character (CR or LF) found in method name 这个错误。

我思量了一下http head也没有改啥东西啊，怎么就CR or LF这俩符号有问题。后来手动输入了一下，问题又解决了，我认为这个问题应该是word文档里的带了windows的行尾符 \r\n ，而在llinux下边只识别\n导致了这个问题。

（

Unix系统里，每行结尾只有“<换行>”，即“\n”；
Windows系统里面，每行结尾是“<回车><换行>”，即“\r\n”；
Mac系统里，每行结尾是“<回车>”,即“\r”。

）

后面自己手动输入，取消了行位换行符，所以后面就可以通讯。
