微信小程序开发手机商城部分代码（不包括支付功能）

以下是我之前学习黑马程序员课程的微信小程序所写的代码 除了支付功能都能实现。如果有错误的地方希望各位大佬能指正一下。

1.搜索框(searchinput)

#wxss
.search_input {
  height: 90rpx;
  padding: 10rpx;
  background-color: var(--themeColor);
}
.search_input navigator {
  height: 100%;
  display: flex;
  justify-content: center;
  align-items: center;
  background-color: #fff;
  border-radius: 15rpx;
  color: rgb(71, 69, 69);
}

2.小程序整体布局

#app.json
{
  "pages":[
    "pages/index/index",
    "pages/category/index",
    "pages/goods_list/index",
    "pages/goos_detail/index",
    "pages/cart/index",
    "pages/collect/index",
    "pages/order/index",
    "pages/search/index",
    "pages/user/index",
    "pages/feedback/index",
    "pages/login/index",
    "pages/auth/index",
    "pages/pay/index"
  ],
  "window":{
    "backgroundTextStyle":"light",
    "navigationBarBackgroundColor": "#ffd68f",
    "navigationBarTitleText": "Market",
    "navigationBarTextStyle":"white"
  },
  "tabBar": {
    "color": "#999",
    "selectedColor": "#0054ff",
    "backgroundColor": "#fff1ff",
    "position": "bottom",
    "borderStyle":"black",
    "list": [
      {
      "pagePath": "pages/index/index",
      "text": "首页",
      "iconPath": "icons/home.png",
      "selectedIconPath": "icons/home_1.png"
    }, 
      {
      "pagePath": "pages/category/index",
      "text": "二手商城",
      "iconPath": "icons/Category.png",
      "selectedIconPath": "icons/Category_1.png" 
    },
      {
      "pagePath": "pages/cart/index",
      "text": "购物车",
      "iconPath": "icons/cart.png",
      "selectedIconPath": "icons/cart_1.png"
    },
      {
      "pagePath": "pages/user/index",
      "text": "我的",
      "iconPath": "icons/my.png",
      "selectedIconPath": "icons/my_1.png"
    }
  ]
  },

  "sitemapLocation": "sitemap.json"
}
 
#app.wxss
@import"./styles/iconfont.wxss";
/* 在微信小程序中 不支持通配符 */
page,view,text,swiper,swiper-item,image,navigator{
  padding: 0; /*内边距*/
  margin: 0; /*外边距*/
  box-sizing: border-box; 
}
/* 主题颜色 通过变量来实现
    1 less中 存在 变量 这个知识
    2 原生的css和wxss 也是支持变量 
*/
page{
  /* 定义主题颜色 */ 
  --themeColor:#ffd68f;
  /* 
  定义统一字体大小 假设设计稿 大小是 375px
  1px=2rpx
 */
    font-size: 35rpx;
 


}
#下面一行代码关系到后面的图片能否正常加载
image{
  width: 100%;
} 

3.局内使用图标

#iconfont.wxss
@font-face {
  font-family: "iconfont"; /* Project id 3176877 */
  src: url('//at.alicdn.com/t/font_3176877_3aikrnlzpca.woff2?t=1646482273692') format('woff2'),
       url('//at.alicdn.com/t/font_3176877_3aikrnlzpca.woff?t=1646482273692') format('woff'),
       url('//at.alicdn.com/t/font_3176877_3aikrnlzpca.ttf?t=1646482273692') format('truetype');
}

.iconfont {
  font-family: "iconfont" !important;
  font-size: 16px;
  font-style: normal;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
}

.icon-biaoqianlan:before {
  content: "\e609";
}

.icon-tuanduizhaomu:before {
  content: "\e60d";
}

.icon-ziyuanpingtai-ziyuangongxiang:before {
  content: "\e608";
}

.icon-xuanchuan:before {
  content: "\e610";
}

.icon-ershou:before {
  content: "\f619";
}

.icon-icon_shoucang_xian:before {
  content: "\e604";
}

.icon-icon_shoucang_mian:before {
  content: "\e616";
}

.icon-daishouhuo:before {
  content: "\e641";
}

.icon-tuikuan:before {
  content: "\e75a";
}

.icon-shouye:before {
  content: "\e643";
}

.icon-daifukuan:before {
  content: "\e640";
}

.icon-dingdan:before {
  content: "\e897";
}

.icon-gouwuche:before {
  content: "\e63f";
}

.icon-kefu:before {
  content: "\e625";
}

.icon-fenxiang:before {
  content: "\eb24";
}

4.封装接口

#asyncWx.js
/**

 */
export const getSetting=()=>{
  return new Promise((resolve,reject)=>{
      wx.getSetting({
          success: (result)=>{
              resolve(result);
          },
          fail: (err)=>{
              reject(err);
          }
      });
  })
}
/**

*/
export const chooseAddress=()=>{
  return new Promise((resolve,reject)=>{
      wx.chooseAddress({
          success: (result)=>{
              resolve(result);
          },
          fail: (err)=>{
              reject(err);
          }
      });
  })
}
/**

*/
export const openSetting=()=>{
  return new Promise((resolve,reject)=>{
      wx.openSetting({
          success: (result)=>{
              resolve(result);
          },
          fail: (err)=>{
              reject(err);
          }
      });
  })
}
/**

*/
export const showModal=({content})=>{
  return new Promise((resolve,reject)=>{
    wx.showModal({
        title: '提示',
        content: content,
        success :(res)=> {
            resolve(res);   
        },
        fail:(err)=>{
            reject(err);
        }
      })
  })
}
/**
* promise形式的 showToast
*/
export const showToast=({title})=>{
    return new Promise((resolve,reject)=>{
        wx.showToast({
            title: title,
            icon:'none',
            success :(res)=> {
                resolve(res);   
            },
            fail:(err)=>{
                reject(err);
            }
        })
    })
}
/**
* promise形式的 login
*/

export const login=()=>{
  return new Promise((resolve,reject)=>{
      wx.login({
        timeout: 10000,
        success:(result)=>{
            resolve(result);
        },
        fail:(err)=>{
            reject(err);
        }
      });
  })
}

/**
* promise形式的 小程序的微信支付
* @param{object} pay 支付所必要的参数
*/
export const requestPayment=(pay)=>{
  return new Promise((resolve,reject)=>{
      wx.requestPayment({
          ...pay,
          success:(result) =>{
              resolve(result)             
          },
          fail:(err)=>{
              reject(err);
          }
      });
  })
}
