{
  "networkTimeout": {
    "request": 10000,
    "downloadFile": 10000
  },
  "navigateToMiniProgramAppIdList": [
    "wxxxxxxxx"
  ],
  "setting": {
    "packNpmManually": true,
    "packNpmRelationList": [
      {
        "packageJsonPath": "./package.json",
        "miniprogramNpmDistDir": "./miniprogram/"
      }

// 在小程序代码中发起网络请求
wx.request({

  method: 'GET',
  success: function(res) {
    console.log(res.data);
  },
