</image>

样式：

/* pages/camera/camera.wxss */

获取图片路径，显示图片和保存

// pages/camera/camera.js
Page({
 
  data: {
    tempFilePaths: 'http://pic2.cxtuku.com/00/01/08/b207004f7104.jpg'
  },
  chooseimage: function () {
    var that = this;
    wx.showActionSheet({
      itemList: ['从相册选择', '拍照'],
      itemColor: "#CED63A",
      success: function (res) {
        if (!res.cancel) {
          if (res.tapIndex == 0) {
            that.chooseWxImage('album')
          } else if (res.tapIndex == 1) {
            that.chooseWxImage('camera')
          }
        }
      }
    })
  },
 
  chooseWxImage: function (type) {
    var that = this
    wx.chooseImage({
      sizeType: ['original', 'compressed'],
      sourceType: [type],
      count: 1,
      success: function (res) {
        console.log(res)
        that.setData({
          tempFilePaths: res.tempFilePaths[0],
        })
      }
    })
  },
  savePhone: function () {
    wx.getImageInfo({
      src: this.data.tempFilePaths,
      success: function (res) {
        var path = res.path
        wx.saveImageToPhotosAlbum({
          filePath: path,
          success: function () {
            wx.showToast({
              title: '保存成功',
            })
          },
          fail: function (res) {
            wx.showToast({
              title: '保存失败',
              icon: 'none'
            })
          }
        })
      }
    })
  }
})
