***.http.converter.HttpMessageNotReadableException: I/O error while reading input message；的解决办法

问题概述

在通过vue-element-admin进行项目的前端脚手架搭建完成后，

前后端数据链路联调时，Request 是发送到后端了，

但是后端报错，错误信息“ org.springframework.http.converter.HttpMessageNotReadableException: I/O error while reading input message; nested exception is ”

如下图：

具体信息如下：

解决办法

关于这个问题，在Express管网文档有描述，如下图：

因为发送的是Post请求，提交的是Body表单，

由上图可知，这样定义的目的是解析vue-element-admin脚手架的mock中定义的json数据，

在mock-server.js中请求的Body就被解析掉了，

而现在是需求Body表单数据请求到后端，

修改方法有两种：

第一种：mock-server.js

如果以后项目中都不用Mock数据了，直接删除掉，

如果以后项目中可能还需要继续使用Mock数据，则可以先把以上两行注释掉即可，

如下图：

第二种：vue.config.js

注释掉mock-server.sj，

如下图：

以上任意一种办法都可行，

修改完成后，需要重启前端，再次请求数据联调接口，就可以正常访问了，如下图：

参考：

【Express4.x-API Reference】
