uniapp设置外网访问

在UniApp中设置外网访问需要进行以下步骤：

1. 在manifest.json文件中配置权限：打开manifest.json文件，添加以下代码：

"permission": {
  "webview": {
    "description": "用于访问外部网络"
  }
}

2. 在App.vue文件中配置网络访问策略：打开App.vue文件，在`<script>`标签中添加以下代码：

export default {
  onLaunch() {
    uni.getSetting({
      success: (res) => {
        if (!res.authSetting['scope.userInfo']) {
          uni.authorize({
            scope: 'scope.userInfo',
            success() {
              // 授权成功
            },
            fail() {
              // 授权失败
            }
          })
        }
      }
    })
  }
}

3. 在manifest.json文件中配置域名白名单：打开manifest.json文件，添加以下代码：

"networkTimeout": {
  "request": 10000,
  "downloadFile": 10000
},
"debug": true,
"appid": "your appid",
"setting": {

},
"networkTimeout": {
  "request": 10000,
  "downloadFile": 10000
},
"debug": true,

"navigateToMiniProgramAppIdList": ["wxe5f529b5d8c3a8e2"],
"permission": {
  "scope.userLocation": {
    "desc": "你的位置信息将用于小程序位置接口的效果展示"
  }
},
"networkTimeout": {
  "request": 10000,
  "downloadFile": 10000
},
"debug": true,
