Invalid character found in the request target , 在SpringBoot2.0.3中的異常解決

阿新 • • 發佈：2018-12-23

異常一：
Invalid character found in method name. HTTP method names must be token
原因：
產生這個問題的原因是頁面表單提交了大量的資料，而這些資料量可能超過了Tomcat 定義的Header頭內容，那麼很好解決了，只要設定一下Tomcat的maxHttpHeaderSize

解決問題如下：

server:
address: 0.0.0.0
port: 8080
max-http-header-size: 10240000
tomcat:
max-http-header-size: 10240000
max-http-post-size: 10240000

異常二：

Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986
原因：
SpringBoot 2.0.0 以上都採用內建tomcat8.0以上版本，而tomcat8.0以上版本遵從RFC規範添加了對Url的特殊字元的限制，url中只允許包含英文字母(a-zA-Z)、數字(0-9)、-_.~四個特殊字元以及保留字元( ! * ’ ( ) ; : @ & = + $ , / ? # [ ] ) (26*2+10+4+18=84)這84個字元,請求中出現了{}大括號或者[],所以tomcat報錯。設定RelaxedQueryChars允許此字元(建議)，設定requestTargetAllows選項(Tomcat 8.5中不推薦)。您可以降級為舊版本之一(不推薦-安全性)。根據

https://tomcat.apache.org/tomcat-8.5-doc/config/systemprops.html, requestTargetAllowis設定允許不受歡迎字元。對我來說，這裡提出的其他解決辦法也不起作用。根據Tomcat文件，我找到了一種方法來設定鬆弛的QueryChars屬性

解決問題如下：

/**
* 解決異常資訊：
* java.lang.IllegalArgumentException:
* Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986
* @return

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