篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Invalid character found in the request target.The valid characters are defined in RFC 7230 and RFC39相关的知识,希望对你有一定的参考价值。
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
参考这里
具体来说:
org.apache.tomcat.util.http.parser.HttpParser#IS_NOT_REQUEST_TARGET[]
中定义了一堆not request target
if(IS_CONTROL[i] || i > 127 || i == 32 || i == 34 || i == 35 || i == 60 || i == 62 || i == 92 || i == 94 || i == 96 || i == 123 || i == 124 || i == 125) {
IS_NOT_REQUEST_TARGET[i] = true;
}
转换过来就是以下字符(对应10进制ASCII看):
- 键盘上那些控制键:(
<32或者=127
) - 非英文字符(
>127
) 空格
(32
)双引号
(34
)#
(35
)<
(60
)>
(62
)反斜杠
(92
)^
(94
)TAB上面那个键,我也不晓得嫩个读
(96
){
(123
)}
(124
)
|
(125
)
解决办法1:
还是参考这里
即:
配置tomcat的catalina.properties
添加或者修改:
tomcat.util.http.parser.HttpParser.requestTargetAllow=|{}
这种方法只适合对应的应为,如果为中文则就不行。如果有?和&这些符合那么
tomcat.util.http.parser.HttpParser.requestTargetAllow=|{}?&
解决办法2:
最轻便的方法,更换tomcat版本。此方法比较快。
解决办法3:
对相应的参数进行编码,就是将所有的参数都进行编码
解决方法4:
选择另外的参数传递方法,比如post或者localStorage。
