WeChat applet obtains album photos

Today I encountered the user avatar setting function of the WeChat applet and took notes.

First upload the gif:

Then add the code:

Small demo, the code is very simple.

1.index.wxml

#

<!--index.wxml--> 
<button style="margin:30rpx;" bindtap="chooseimage">获取图片</button> 
<image src="{{tempFilePaths }}" mode="aspecFill" style="width: 100%; height: 450rpx"/>

2.index.js

//index.js 
//获取应用实例 
var app = getApp() 
Page({ 
 data: { 
  tempFilePaths: '' 
 }, 
 onLoad: function () { 
 }, 
 chooseimage: function () { 
  var _this = this; 
  wx.chooseImage({ 
   count: 1, // 默认9 
   sizeType: ['original', 'compressed'], // 可以指定是原图还是压缩图，默认二者都有 
   sourceType: ['album', 'camera'], // 可以指定来源是相册还是相机，默认二者都有 
   success: function (res) { 
    // 返回选定照片的本地文件路径列表，tempFilePath可以作为img标签的src属性显示图片 
    _this.setData({ 
     tempFilePaths:res.tempFilePaths 
    }) 
   } 
  }) 
 } 
})

API Description:

Note here: What is returned is the local path of the image. If you need to upload the image to the server, you need to use another API.

Sample code:

wx.chooseImage({ 
 success: function(res) { 
  var tempFilePaths = res.tempFilePaths 
  wx.uploadFile({ 
   url: 'http://example.weixin.qq.com/upload', //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 
   } 
  }) 
 } 
})
