效果图：
实现方法：
一、通过uni.chooseMedia(OBJECT)方法，拍摄或从手机相册中选择图片或视频。
官方文档链接: https://uniapp.dcloud.net.cn/api/media/video.html#choosemedia
javascript
uni.chooseMedia({
count: 9,
mediaType: ['image','video'],
sourceType: ['album', 'camera'],
maxDuration: 30,
camera: 'back',
success(res) {
console.log(res.tempFiles)
}
})二、使用uni.uploadFile(OBJECT)方法上传文件。
官方文档链接: https://uniapp.dcloud.net.cn/api/request/network-file.html#uploadfile
javascript
uni.chooseImage({
success: (chooseImageRes) => {
const tempFilePaths = chooseImageRes.tempFilePaths;
uni.uploadFile({
url: 'https://www.example.com/upload', //仅为示例，非真实的接口地址
filePath: tempFilePaths[0],
name: 'file',
formData: {
'user': 'test'
},
success: (uploadFileRes) => {
console.log(uploadFileRes.data);
}
});
}
});
javascript
var uploadTask = uni.uploadFile({
url: 'https://www.example.com/upload', //仅为示例，并非真实接口地址。
complete: ()=> {}
});
uploadTask.abort();三、使用progress进度条组件，实现上传进度显示。
三、完整代码。
功能：1、上传图片支持进度显示 2、控制每张图片大小不超过8兆 3、当选择图片超过最大数量时，添加图片按钮控制隐藏
javascript
