java.lang.IllegalArgumentException: Invalid character found in method name [0x160x030x0

问题

在使用浏览器访问后端进行测试时，发现出现了以下异常：

java.lang.IllegalArgumentException: Invalid character found in method name [0x160x030x010x020x000x010x000x010xfc0x030x03_60xe20xa5Y0xeau0x17'u/0x860xc1]5l640x840xa1Q,0xa50x810x880xa1l0xf50x11].

解决方案

这个异常的意思就是在方法中有非法的参数，可我自己检查了后端接口，发现并没问题，于是我觉得问题应该出在请求上。果然，我发现我写的ajax请求地址写的是 https，可是我并没有加密，是无法用https协议的，将https改为http即可。特此记录。
