The default is to get photos from albums and take pictures with a camera. Like the interface in which Wechat now selects pictures, the first frame is to take photos, followed by album photos.

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

Sample code:

1 wx.chooseImage ({2 success: function (res) {3 var tempFilePaths = res.tempFilePaths4 wx.uploadFile ({5 url: 'http://example.weixin.qq.com/upload', / / for example only) Non-real interface address 6 filePath: tempFilePaths [0], 7 name: 'file',8 formData: {9' user': 'test'10}, 11 success: function (res) {12 var data = res.data13 / / do something14} 15}) 16} 17}) these are all the contents of this article entitled "how Mini Program gets pictures from photo albums and uploads them and uses the camera to take pictures".
