今天升级tomcat7.0.84遇到一个问题:url请求中包含\{\}的都报错:

二月 06, 2018 5:25:39 下午 org.apache.coyote.http11.AbstractHttp11Processor process
    信息: Error parsing HTTP request header
     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:192)
        at org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1028)
        at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:637)
        at org.apache.tomcat.util.net.JIoEndpoint$SocketProcessor.run(JIoEndpoint.java:318)
        at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145)
        at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615)
        at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61)
        at java.lang.Thread.run(Thread.java:745)

前台的请求及报错如下:

Failed to load resource: the server responded with a status of 400 (Bad Request)
    
    
    http://localhost:8080/XXX/formshow/show.jsp?formId=1222&processFormType=CREATE&formUsage=INPUT&initData={
       %22flowId%22:%22180206172500073%22,%22flowTypeId%22:%228%22,%22flowType%22:%22WFM%22,%22processNameEn%22:%22com.inspur.plugins.ge.process.GenerateElectricity%22,%22processNameZh%22:%22GE%22,%22processPluginName%22:%22ge%22,%22formType%22:%22JSP%22,%22version%22:%221.1.1%22,%22jspformService%22:%22generateElectricityCreateJspFormService%22}

### 问题分析: ###

错误代码 400 **请求参数有误**：

升级tomcat之后就出现了这个问题，Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986，也就是说我们的请求中用了无效的字符。查看RFC规范知,url中只允许包含英文字母(a-zA-Z)、数字(0-9)、-\_.~四个特殊字符以及保留字符( ! \* ’ ( ) ; : @ & = + $ , / ? \# \[ \] ) (26\*2+10+4+18=84)这84个字符.而我们的请求中出现了\{\}大括号,所以tomcat报错.

### 解决办法(四种): ###

1.  **替换url请求。**不用\{\}
2.  **对请求编码解码。** UrlDecode、UrlEncode
3.  **配置Tomcat对字符的支持** (见下文)
4.  **更换Tomcat版本** (注,Tomcat从 7.0.73, 8.0.39, 8.5.7 版本后添加了对Url的限制。)
    
     *  配置tomcat支持|\{\}等字符的方法是:在 **catalina.properties**中添加 **tomcat.util.http.parser.HttpParser.requestTargetAllow=|\{\}** 但是只支持7.0.76, 8.0.42, 8.5.12 之后的版本(这些版本之后支持设置上述属性)
     *  注,Tomcat从 **7.0.73, 8.0.39, 8.5.7 版本**后添加了对Url的限制。
