当时我试着把json格式分成两部分
分别使用Feign接口调用服务间方法时都能调用 合在一起时就出现标题错误感觉奇怪
后续百度之后发现可能是由于JSON长度太大了 默认Feign的调用长度在2048 所以出现这个问题
解决办法：
1.在applucation.yml中增加配置：
feign:
compression:
request:
min-request-size: 30000
注意的是 倘若nacos的配置中也存在这个配置的话 在application.yml中配置就被nacos的配置顶掉了(笔者就是犯了这个错误.......) 默认配置优先级是nacos配置>本机配置 特此贴图告示一下：
