uni-app 使用axios 分享 ，解决： adapter is not a function

uni-app 使用axios 真机会提示： adapter is not a function 。我也不懂，我也不会，就菜鸟一个。

然后跟了下问题所在，好像调用不到xhr.js ，
翻到这里 var adapter = config.adapter || defaults.adapter; 报错。

参考：

https://blog.csdn.net/u013704958/article/details/90713386 我借鉴5楼提供的方法，用uni.request 来调用
https://ext.dcloud.net.cn/plugin?id=930

添加了一段代码，重新引用
//真机获取
axios.defaults.adapter = function (config) {....}
