The applet obtains the photo album

Today, I met with the user profile picture setting function of the mini program and took notes.

First Upload gif:

  Get image 

2. index. js

// Index. js // Obtain the application instance var app = getApp () Page ({data: {tempFilePaths: ''}, onLoad: function () {}, chooseimage: function () {var _ this = this; wx. chooseImage ({count: 1, // Default 9 sizeType: ['original', 'compressed '], // you can specify whether the source image or the compressed image is used. Both have sourceType by default: ['alipay', 'Camera '], // you can specify whether the source is an album or a camera. Both have success: function (res) by default) {// return the local file path list of the selected image. the tempFilePath can be used as the src attribute of the img label to display the image _ this. setData ({tempFilePaths: res. tempFilePaths })}})}})

API description:

Wx. chooseImage ({success: function (res) {var tempFilePaths = res. tempFilePaths wx. uploadFile ({url: 'http: // example.weixin.qq.com/upload', // only for example. The non-real interface address is filePath: tempFilePaths [0], name: 'file', formData: {'user': 'test'}, success: function (res) {var data = res. data // do something }})}})
