【微信小程序】TypeError: Cannot read property ‘get‘ of undefined & Error: MiniProgramError

简介: 【微信小程序】TypeError: Cannot read property ‘get‘ of undefined & Error: MiniProgramError



一、问题场景

  在写 uni-app 项目的时候,跟着视频一步一步的弄,一运行就发现报错了,然后就开始各种百度了。

找不到定义

WAServiceMainContext.js?t=wechat&s=1680006165208&v=2.30.2:1 TypeError: Cannot read property ‘get’ of undefined

at _callee$ (home.js? [sm]:16)

at L (regenerator.js:1)

at Generator._invoke (regenerator.js:1)

at Generator.t. [as next] (regenerator.js:1)

at asyncGeneratorStep (asyncToGenerator.js:1)

at c (asyncToGenerator.js:1)

at asyncToGenerator.js:1

at new Promise ()

at asyncToGenerator.js:1

at Proxy.getSwiperList (home.js? [sm]:15)(env: Windows,mp,1.06.2301160; lib: 2.30.2)

找不到请求路径

WAServiceMainContext.js?t=wechat&s=1680009054414&v=2.30.2:1 Error: MiniProgramError

{“errno”:600009,“errMsg”:“request:fail invalid url “/api/public/v1/home/swiperdata””}

at Le (WASubContext.js?t=wechat&s=1680009054414&v=2.30.2:1)

at WASubContext.js?t=wechat&s=1680009054414&v=2.30.2:1(env: Windows,mp,1.06.2301160; lib: 2.30.2)

二、问题分析

  根据百度和ChatGPT,chatGPT回答如下:

  可以发现,原来是导入模块以及定义放在了 Vue3 定义中,导致页面上使用的时候找不到该引入。

// #ifndef VUE3

// #endif

三、问题解决

  将导入模块以及定义方式放在 // #ifndef VUE3 外面,这样就能解决问题了

import { $http } from '@escook/request-miniprogram'
uni.$http = $http
// 配置请求根路径
$http.baseUrl = 'https://www.uinav.com'
// #ifndef VUE3
import Vue from 'vue'
import App from './App'
// 请求拦截器
$http.beforeRequest = function(options){
  uni.showLoading({
    title:'数据加载中...'
  });
}
// 响应拦截器
$http.afterRequest = function(){
  uni.hideLoading();
}
Vue.config.productionTip = false
App.mpType = 'app'
const app = new Vue({
    ...App
})
app.$mount()
// #endif

  在微信开发者工具中也能请求到的 data 数据:
