后台报错如下

java.lang.IllegalArgumentException: Invalid character found in the request target [/mes/sys/files/getImgBytes?url=\mesFile\9d61397c-dafc-479a-b86c-288d06627f91_f58f86fc-3497-4081-b9b3-897dbc610963.png ].

错误分析

从错误信息来看，问题出在请求的目标路径中包含了非法字符。根据RFC 7230和RFC 3986的规定，URL中的某些字符是不允许直接使用的，例如空格、反斜杠（\）等。我的请求路径中包含了一个反斜杠（\mesFile\96609415-5070-4de9-b718-a1e478abff6b_f58f86fc-3497-4081-b9b3-897dbc610963.jfif），这在URL中是不合法的。
