**报错信息：**

org.apache.coyote.http11.AbstractHttp11Processor.process 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

**分析访问路径：**

前端以jsonString的格式传递给后端，后端以String 接收

http://localhost:8080/channel/export?searchParams={"afterTime":"2019-01-07","beforeTime":"2019-01-07"}

如果我将\{...\}的信息换成一个字符串又是可以的，所以问题出在\{...\}这里

**解决方案：**

1、去除URL中的特殊字符；

3、使用 Post 方法提交数据

4、更换低版本的Tomcat来规避这种问题。

5、在 conf/catalina.properties  添加或者修改：

tomcat.util.http.parser.HttpParser.requestTargetAllow=|{}

Tomcat在 7.0.73, 8.0.39, 8.5.7 版本后，添加了对于http头的验证。   
具体来说，就是添加了些规则去限制HTTP头的规范性

**总结：**
