tomcat版本:7.0.93
报错信息如下:
Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level. java.lang.IllegalArgumentException: Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986 at org.apache.coyote.http11.InternalInputBuffer.parseRequestLine(InternalInputBuffer.java:194) at org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1050) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:637) at org.apache.tomcat.util.net.JIoEndpoint$SocketProcessor.run(JIoEndpoint.java:317) 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)
具体分析如下:
tomcat添加了对header请求头的验证,因请求路径中带有[]{}等字符,所以无法通过校验。
解决方案:
1、去除URL中的特殊字符;
2、使用 Post 方法提交数据
3、更换低版本的Tomcat来规避这种问题。
4、在 conf/catalina.properties 添加或者修改:
tomcat.util.http.parser.HttpParser.requestTargetAllow=|{}
该配置只对以上三种特定字符有效。
5、在 conf/server.xml <Connector> 节点下添加:
relaxedPathChars=""<>[\]^`{|}"
relaxedQueryChars=""<>[\]^`{|}"
如下:
<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" relaxedPathChars=""<>[\]^`{|}" relaxedQueryChars=""<>[\]^`{|}" />
如果是springboot项目则将webServerFactory方法加入到springboot启动类
@Configuration public class TomcatConfig { @Bean public TomcatServletWebServerFactory webServerFactory() { TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory(); factory.addConnectorCustomizers((Connector connector) -> { connector.setProperty("relaxedPathChars", ""<>[\]^`{|}"); connector.setProperty("relaxedQueryChars", ""<>[\]^`{|}"); }); return factory; } }
经测试之后,该问题解决!
ps :如何解决tomcat乱码问题
在Connector节点下添加属性 URIEncoding="UTF-8"即可。
