Weixin Mini Programs photo upload functionBased on context alone
The photo upload function of the Weixin Mini Programs has the following features and implementation methods:
** 1. Function and Specialties **
1. ** Ease **
- It provided users with a way to quickly obtain photos and upload them directly in the Mini programs environment without switching to the phone's native camera application and then back to operate. For example, in some ID photo-making Mini programs, users could take photos directly and upload them for subsequent operations such as cutting, beautification, and size adjustment.
2. ** Device compatibility **
- It was very suitable for all types of mobile devices, whether it was an Android phone or an Apple phone, it could normally call the camera to take photos and upload them.
3. ** Authority Management **
- Before using the photo upload function, Mini programs would ask the user to grant the camera and storage (to save the photos taken for upload) permission. The user can choose to allow or reject it according to their needs.
** 2. Realization Method **
1. ** Code Development **
- In the front end development of the Mini programs, it was mainly implemented using the application programming interface (api) of the Weixin Mini Programs. For example, you can use the relevant APIs such as `wx.chooseMedia` or `wx. createCameraContext'.
- Take `wx.chooseMedia` as an example. The developer can set `sourceType` to `['camera']` to specify that only photos can be obtained from the camera, and then set `count` to limit the maximum number of photos that the user can choose (if you only want the user to upload one photo, you can set it to 1).
- After obtaining the temporary path of the photo, he could upload the photo to the server through the network request. This usually involved interacting with the back-end server, which could use various programming languages (such as Python's Flask, Django framework, and the Spring framework of Java) to receive and process the uploaded photos.
2. ** Security and Data Processing **
- During the upload process, in order to ensure the security of the data, the photos were usually encrypted. At the same time, the server would also check the validity of the received photos, such as checking whether the file format meets the requirements (common format such as JPEG, PNG, etc.) to prevent malicious files from being uploaded.
