1. 页面上的axios请求返回没有cookie。通过Charles抓包，在chrome上请求回来能看到cookie，但在capacitor android app上看不到cookie。一开始以为是capacitor的问题，后来搜到在app中hostname默认是localhost，但cookie的domain是web.hjdang.com,导致获取不到cookie。改了下配置，增加hostname：app.hjdang.com，结果发现请求都发不出去。再次改成www.hjdang.com就好了。

{
  "appId": "org.capacitor.hjdang",
  "appName": "好家当",
  "bundledWebRuntime": false,
  "npmClient": "[object Object]",
  "webDir": "www",
  "plugins": {
    "LiveUpdates": {
      "appId": "3d5dd39b",
      "channel": "Production",
      "autoUpdateMethod": "background",
      "maxVersions": 2
    }
  },
  "server": {
    "androidScheme": "https",
    "hostname": "www.hjdang.com"
  }
}

　　以上解决方式发现是在capacitor的webview里直接打开了www.hjdang.com这个网址所以没问题。但这却没有用到app里本地localhost的网页。后来经过一阵搜索，发现需要用到CapacitorHttp这个plugin

 在app里不适合用cookie的方式来auth，而适合awt的方式 /bearer token

Cookies are used to remember something in the stateless environment. An app is not stateless.
