好了，这是图片轮播的几个文件。会在app.json中配置。


接下来是图片上传的。因为没有服务器，暂时不能上传，但是可以从本地相册或拍照获取照片。
upload.js:




var app = getApp()  
Page({ 
  data:{ 
  // text:"这是一个页面" 
  source: '', 
  tt:false 
 }, 
 /** 
  * 选择相册或者相机 配合上传图片接口用 
  */ 
 onLoad: function() { 
   var that = this; 
   wx.chooseImage({ 
     count: 1, 
     //original原图，compressed压缩图 
     sizeType: ['original'], 
     //album来源相册 camera相机  
     sourceType: ['album', 'camera'], 
     //成功时会回调 
     success: function(res) { 
       //重绘视图 
       that.setData({ 
         source: res.tempFilePaths, 
         tt:true 
       }) 
       /* var tempFilePaths = res.tempFilePaths 
      wx.uploadFile({ 
      url: 'https://', //仅为示例，非真实的接口地址 
      filePath: tempFilePaths[0], 
      name: 'file', 
      formData:{ 
      'user': 'test' 
      }, 
      success: function(res){ 
      var data = res.data 
      //do something 
      } 
    })*/ 
     } 
   }) 
 }, 
 /*onHide:function(){ 
   this.setData({ 
     source:'' 
   }) 
 }*/ 
}) 



upload.json:




{ 
  "navigationBarTitleText": "上传图片" 
} 



upload.wxml:




<view class="Container"> 
<image src="/UploadFiles/2021-04-02/{{source}}">

upload.wxss:




/* pages/upload/upload.wxss */ 
.Container{ 
  text-align:center; 
  width:100%; 
} 
.image-i{ 
  width:100%; 
  height:100%; 
} 



app.js为空。
