说明

本demo会用到微信小程序的云开发功能,包括云数据库,云存储

实现步骤

1. 云开发环境的初始化

详见:https://blog.csdn.net/Panda325/article/details/108117775

2. 新建page

新建两个pagesharepyqshare用于编辑文案并选择配图,pyq用于查看以前发过的朋友圈
app.jsonpages字段如下:

"pages": [
    "pages/share/share",
    "pages/pyq/pyq"
  ],

在这里插入图片描述

3. share页面

share页面从上到下依次是:多行输入框 textarea,选择图片的按钮 button,分享按钮 button
share.wxml如下:

<textarea placeholder="输入您的文案" bindblur="bindTextAreaBlur"
   value="{{details}}" class='text'> </textarea>
<input>\n\n</input>
<button bindtap="seleteAndUploadPicture">
<image src='https://ss0.bdstatic.com/70cFvHSh_Q1YnxGkpoWK1HF6hhy/it/u=2444066247,3899866315&fm=26&gp=0.jpg'></image>
</button>
<input>\n\n</input>
<button bindtap="share">分享</button>

share.js如下:

const DB = wx.cloud.database().collection("pyq")
Page({
 data: {
   details: '',
   imgURL: ''
 },
 bindTextAreaBlur: function (e) {
   console.log(e.detail.value);
   var that = this;
   that.setData({
     details: e.detail.value
   });
 },
 seleteAndUploadPicture() {
   let that = this
   wx.chooseImage({
     count: 1,
     sizeType: ['original', 'compressed'],
     sourceType: ['album', 'camera'],
     success: res => {
       console.log('choose successfully', res)
       that.setData({
         imgURL: res.tempFilePaths[0]
       })
     },
     fail(res) {
       console.log('choose failed', res)
     }
   })
 },
 share() {
   console.log('调用share的方法')
   let that = this
   wx.cloud.uploadFile({
     cloudPath: new Date().getTime() + '.png',
     filePath: this.data.imgURL, // 文件路径
     success: function (res) {
       console.log('upload successfully', res)
       that.setData({
         imgURL: res.fileID
       })
     },
     fail(res) {
       console.log('upload failed', res)
     }
   })
   DB.add({
     data: {
       descption: this.data.details,
       imgURL: this.data.imgURL
     },
     success(res) {
       console.log("share成功", res)
       wx.navigateTo({
         url: "../../pages/pyq/pyq"
       })
       wx.showToast({
         title: '成功',
         icon: 'success',
         duration: 2000
       })
     },
     fail(res) {
       console.log("share失败", res)
     }
   })
 }
})

share.wxss如下:

.text{
 /* height: 100rpx;
 line-height: 100rpx; */
 width: 100%;
 font-size: 60rpx;
 background-color: #bfa;
}

4. pyq页面

pyq.wxml如下:

<view wx:for="{{array}}">
<view>{{index}} : {{item.descption}}</view>
<image src="{{item.imgURL}}"></image>
<view>\n</view>
</view>

pyq.js如下:

const DB = wx.cloud.database().collection("pyq")
Page({
 data: {
   array: []
 },
 onLoad() {
   let that = this
   DB.get({
     success(res) {
       that.setData({
         array: res.data
       })
       for (let i = 0; i < res.data.length; i++) {
         console.log(res.data[i].descption)
         console.log(res.data[i].imgURL)
       }
     }
   })
 }
})
