问题描述

使用Postman调用Java api解密token时

token值为iRdLmVEYUUvoH1oDF2QhSVhJxXYMRCxzbtJsL01Iun2OLHY/FxNQOrAwF4Bj2cdp1vhsXt9BQtc+xmiyuCvyi2+Itl2qlvlCT6VwRM6UgQ5SBIiInGlLYCr+zDfOoQ74zh+xwW7M+43vIuLs6W0y7Rt86uZgmAR8gYwMLfvGnRg=

 执行时报错如下：

原因分析

后台会自动转义特殊字符，如'+'被转义为空格。

解决方案

前端将token传给后端之前，将token先转义

 iRdLmVEYUUvoH1oDF2QhSVhJxXYMRCxzbtJsL01Iun2OLHY%2FFxNQOrAwF4Bj2cdp1vhsXt9BQtc%2BxmiyuCvyi2%2BItl2qlvlCT6VwRM6UgQ5SBIiInGlLYCr%2BzDfOoQ74zh%2BxwW7M%2B43vIuLs6W0y7Rt86uZgmAR8gYwMLfvGnRg%3D

后端接收到被转义的字符串，会自动反转义，得到

iRdLmVEYUUvoH1oDF2QhSVhJxXYMRCxzbtJsL01Iun2OLHY/FxNQOrAwF4Bj2cdp1vhsXt9BQtc+xmiyuCvyi2+Itl2qlvlCT6VwRM6UgQ5SBIiInGlLYCr+zDfOoQ74zh+xwW7M+43vIuLs6W0y7Rt86uZgmAR8gYwMLfvGnRg=

postman需要转义，swagger则无需转义。
