How to turn off the album selection function in uniapp

With the continuous development of mobile Internet, mobile applications have become an indispensable part of people's lives. It is convenient and fast to use the uniapp framework when developing mobile applications, but sometimes we need to integrate the system functions of the mobile phone into our applications. This article mainly describes how to close uniapp and select the album.

When we develop an application, we often need to call the photo album function of the mobile phone to select or take photos. In the uniapp framework, we can use the uni.chooseImage() function in uni-ui to implement the function of uploading images, but in some scenarios, selecting an album is not necessary. So how to close uniapp and select the album? Next let us look at the implementation steps.

Step one: Modify the manifest.json file

manifest.jsonThe file is the configuration file of the uniapp project. We need to make changes in this file to achieve shutdown Select the function of the album. Find the "permissions" attribute in the file. This attribute is used for permission management of the application. Just add the required permissions. As follows:

"permissions": {
    "camera": {
        "desc": "拍照功能"
    },
    "saveImageToPhotosAlbum": {
        "desc": "保存图片到本地相册"
    }
}

In the above code, we added the "camera" and "saveImageToPhotosAlbum" permissions and described them accordingly. "camera" is used for taking pictures, "saveImageToPhotosAlbum" is used for saving pictures to the local album.

Step 2: ClosechooseImageFunction

chooseImageThe function is the core function for uploading pictures in uniapp, and its closing also closes the selected album main method. When we call the chooseImage function, we set its second parameter, which is to select the image source, to take a photo, so that we can block the album selection function, as shown below:

uni.chooseImage({
    count: 1,
    sourceType: ['camera'], // 选择来源为相机
    success: function (res) {
        console.log('chosed success')
    }
})

In the above code , we set sourceType to ['camera'], indicating that pictures can only be selected from the camera.

Of course, if you need to allow taking photos and selecting photos from the album in certain scenarios, you can add ['camera', ' album'], the details are as follows: <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false">uni.chooseImage({     count: 1,     sourceType: ['camera', 'album'], // 既可以从相机中选择，也可以从相册中选择     success: function (res) {         console.log('chosed success')     } })</pre><div class="contentsignin">Copy after login</div></div>As can be seen from the above code, we added

['camera', 'album'] to the

sourceType attribute , indicating that you can select from the camera or the photo album. This article mainly introduces how to close the method of selecting an album in the uniapp framework. The article mentions two methods: one is by modifying the

manifest.json

file, and the other is by closing the chooseImageFunction implementation. You can choose the corresponding method according to your actual needs. In short, with the continuous development of technology, we can better integrate the system functions of mobile phones into our applications and improve the user experience. Although uniapp has provided us with a method to select an album, if we do not need this function, we can also turn it off through the above method.
