Javascript React本机AXIOS方法获取响应。数据显示为null

正在尝试使用axios方法get和本地IP获取有关React Native的数据

使用XAMPP在本地主机上运行URL在web上运行良好

但是，当尝试在React Native上使用api调用获取数据时，它在console.log（）上将

response.data

显示为

null

下面是代码片段：

登录屏幕成功显示console.log（）上的用户令牌和用户类型

signnscreen.js

我可以在axios中将方法视为post，请检查axios中的方法post是否用于SignInScreen.js登录。然而，问题是来自freegorscreen.js。问题可能在于授权：AsyncStorage.getItem（'my_token'）hi@ZeeshanAnsari，我也有同样的想法，但仍然不能完全确定。尽管如此，您能否提供一种正确的方式来设置授权以获取令牌？谢谢。你能用请求截图发布你的本地主机响应吗
