Use uniapp to implement the camera function

Using uniapp to implement the camera function

Recently, I just learned uniapp and learned how to implement the camera function in uniapp. Today, I will share with you my learning process and specific code examples.

First of all, to implement the camera function in uniapp, we need to use the uni-app plug-in, which is the uview-ui plug-in. uview-ui is a UI library based on the uni-app framework. It provides a rich set of components and tool functions, allowing us to easily implement various functions in uni-app.

Let us go directly to the specific steps to implement the camera function:

Step 1: Install the uview-ui plug-in
Open your uni-app project in HBuilderX or other development tools, Right-click and select "Plug-in Installation->uView-UI Quick Plug-in Installation", and then follow the prompts to complete the plug-in installation.

Step 2: Introduce the uview-ui component
In the vue file of the page that needs to use the camera function, add the following code:

In the above code, we use u -cell and u-cell-group components to create an entry button for taking photos. When the user clicks the button, the takePhoto method is called. This method uses the uni.chooseImage function to choose to take a picture.

Step 3: Run the project
After completing the writing of the code, we can run the project and experience the camera function. Click the Run button in HBuilderX, select the corresponding running environment (such as WeChat applet), then open the corresponding applet on your phone, and you can see the photo button on the page.

When you click the photo button, the phone's camera will be activated and you can take photos. After the photo is taken, you can see the temporary file path of the photo in the console. You can upload or save the photo as needed.

Using uniapp to implement the camera function is very simple and only requires a few lines of code to complete. By introducing the uview-ui plug-in, we can easily build beautiful and fully functional uni-app applications.

I hope this article is helpful to you, and I hope you can successfully implement the photo taking function. Happy programming!
