1.post请求
/*** @desc: (gateway主要接收前端请求 ， 然后对请求的数据进行验证 ， 验证之后请求反向代理到服务器 。*当请求 method 为 GET 时 ， 可以顺利通过gateway 。 当请求 method 为 POST 时 ， gateway则会报如下错误 。*java.lang.IllegalStateException : Only one connection receive subscriber allowed.*实际上spring - cloud - gateway反向代理的原理是 ， 首先读取原请求的数据 ， 然后构造一个新的请求 ，*将原请求的数据封装到新的请求中 ， 然后再转发出去 。 然而我们在他封装之前读取了一次request body ，*而request body只能读取一次 。 因此就出现了上面的错误 。*解决方案 ： 读取request body的时候 ， 我们再封装一次request ， 转发出去)*/
