获取header中的token串&&http的patch方式发送请求

Posted 2021-12-29 健康平安的活着

一  java后端获取token串

使用java代码获取前端发来的请求header中的token串，

1.1 模拟登陆，获取token

地址：http://10.130.7.118:81/cas/jwt/login

方式：post

header：content-type：application/x-www-form-urlencoded

 请求参数：

 1.2 请求上下线的接口地址

请求地址中：header设置token，进行请求

 1.3  请求自定义的程序，获取header的token

后端代码：

 打印的日志：

 二 java后端模拟http的pacth的方式进行请求

方式一： 使用URL类的方式请求，使用patch，返回包405错误，不支持patch方式吧

 方式二：使用httpclient方式： 能够获取到header的信息，状态码，获取返回的数据，通过httpEntity也无法获取数据，但是通过     result=EntityUtils.toString(entity,"UTF-8");解析后就能返回数据；但是感觉查询耗时比较长。

 

 postman返回结果

 httpclient的依赖
