spring 引导中的请求目标中发现无效字符

Question

我的应用程序是用 java -jar 启动的，版本为 1.5.6.RELEASE of spring boot.
我的请求之一的内容具有字符“{”。当它被发送到服务器时引发以下异常：

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.Http11InputBuffer.parseRequestLine(Http11InputBuffer.java:472) at org.apache.coyote.http11.Http11Processor.service(Http11Processor.java:683) at org.apache.coyote.AbstractProcessorLight.process(AbstractProcessorLight.java:66) at org.apache.coyote.AbstractProtocol$ConnectionHandler.process(AbstractProtocol.java:868) at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1455) at org.apache.tomcat.util.net.SocketProcessorBase.run(SocketProcessorBase.java:49) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.lang.Thread.run(Thread.java:745)

哪里错了？我该如何解决？

编辑 1：
我的休息是这样的：

var jsonData = {
                    id: $("#hiddenId").val(),
                    permitNumber: $("#txtPermitNumber").val(),
                    permitToDate: $("#txtPermitToDate").val()
               }
document.location = restUrl + "/print?reportParams= " + JSON.stringify(jsonData);

Answer 1

您将像这样启动 Spring 启动应用

$ java -jar -Dtomcat.util.http.parser.HttpParser.requestTargetAllow=|{}
 demo-0.0.1-SNAPSHOT.jar

或像这样编码 uri

document.location = restUrl + "/print?reportParams= " + encodeURI(JSON.stringify(jsonData));

Answer 2

简单的方法就是将此代码添加到您的主 class

System.setProperty("tomcat.util.http.parser.HttpParser.requestTargetAllow", "{}");

Answer 3

根据 https://tomcat.apache.org/tomcat-8.5-doc/config/systemprops.html，requestTargetAllow 已弃用。对我来说，这里介绍的其他解决方案也不起作用。根据 Tomcat 文档，我找到了一种设置属性 relaxedQueryChars 的方法：

@Bean
public ConfigurableServletWebServerFactory webServerFactory() {
    TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();
    factory.addConnectorCustomizers(new TomcatConnectorCustomizer() {
        @Override
        public void customize(Connector connector) {
            connector.setProperty("relaxedQueryChars", "|{}[]");
        }
    });
    return factory;
}

Answer 4

对于 Spring Boot 1.5。17.RELEASE。以下代码对我有用。

@Configuration
public class ServerConfig {

    @Bean
    public EmbeddedServletContainerFactory webServerFactory() {
        TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory();
        factory.addConnectorCustomizers(new TomcatConnectorCustomizer() {
            @Override
            public void customize(Connector connector) {
                connector.setProperty("relaxedQueryChars", "|{}[]");
            }
        });
        return factory;
    }

}

Answer 5

请求端编码为Base 64字符串，控制器端解码

编码

btoa(string)

解码：

String arr = request.getParameter();
arr = new String(Base64.getDecoder().decode(arr))

Answer 6

对于 Spring 引导 (2.X) 应用程序，只需添加到属性文件：

server.tomcat.relaxed-query-chars=|,{,},[,]

还有如下键值：server.tomcat.relaxed-path-chars

Answer 7

对于 Spring 启动应用程序，在属性文件中包含：

server.tomcat.additional-tld-skip-patterns=xercesImpl.jar,xml-apis.jar,serializer.jar,xml-apis.jar,jaxb-core.jar,jaxb-api.jar

Answer 8

如果你使用application.yaml只需添加以下配置

server:
  tomcat:
    relaxed-query-chars: '|,{,},[,]'
