Java跨session实现token接口测试过程图解

 //获取返回的token ,使用JsonPath获取json路径
   public static HashMap<String,String> getToken(CloseableHttpResponse closeableHttpResponse,String jsonPath) throws Exception{
     HashMap<String,String> responseToken = new HashMap<String, String>();
     String responseString = EntityUtils.toString( closeableHttpResponse.getEntity(),"UTF-8");
     ReadContext ctx = JsonPath.parse(responseString);
     String Token = ctx.read(jsonPath); //"$.EFPV3AuthenticationResult.Token"
     if(null == Token||"".equals(Token)){
       new Exception("token不存在");
     } 
     responseToken.put("x-ba-token",Token);
     return responseToken;
   }
