二次开发中，我在浏览器的网络请求面板能看到响应头里有 count 参数，但通过 Axios 获取响应头时却找不到这个参数，应该是后端没有配置跨域响应头暴露规则，这个应该怎么解决呢

这是console输出的

这是请求体头返回的数据

这个 getTableList 函数是你们自己二开写的吗，后端调用的哪个服务？也是 core 吗？
然后再把你们自己写的这个 getTableList 的完整请求信息发一下

[Zz]

function getTableList(name, data = {}) {
return axios.get(core/t/${name}/d+setParams(data))
}

query：
{"skip":0,"limit":10,"filter":{"name":{}},"project":{"name":1,"deviceType":1,"state":1,"code":1,"specification":1,"model":1,"serial":1,"location":1,"supplier":1,"manufacturer":1,"installTime":1,"buyTime":1,"files":1,"remark":1,"relevanceUser":1,"relevanceDept":1},"sort":{},"withCount":true}

后端调用的哪个服务？

[Zz]

没太明白你说的哪个服务是什么意思，http://192.168.1.31:3030/rest/core/t/device_table/d，请求的这个接口是iot放出来的接口。

[Zz]

http://192.168.1.31:3030/rest/core/t/device_table/d，这个api路径来看，应该是core服务吧，你们本地有试过前端页面跨域访问设备列表api，能取到count这个字段吗

[Zhang书书]

正常的话只要配置了withCount就可以的，我们这边前端调用是可以正常取到数据的
