uniapp中上传多张图片

在微信小程序中不支持多张图片上传，需要做循环实现多张图片上传

// 官方这边是只能一次上传一张
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);
            }
        });
    }
});

上传多张（做循环）

uni.chooseImage({
    success: (chooseImageRes) => {
        const tempFilePaths = chooseImageRes.tempFilePaths;
        for(let i = 0;i < tempFilePaths.length; i++) {
        	uni.uploadFile({
	            url: 'https://www.example.com/upload', //仅为示例，非真实的接口地址
	            filePath: tempFilePaths[i],
	            name: 'file',
	            formData: {
	                'user': 'test'
	            },
	            success: (uploadFileRes) => {
	                console.log(uploadFileRes.data);
	            }
	        });
        }
    }
});

如果是app或者h5端，可以设置files实现多张图片上传

uni.chooseImage({
    success: (chooseImageRes) => {
        const tempFilePaths = chooseImageRes.tempFilePaths;
        let imgs = tempFilePaths.map((value, index) => {
        	return {
        	name: index,
        	uri: value
        })
        uni.uploadFile({
            url: 'https://www.example.com/upload', //仅为示例，非真实的接口地址
            files: imgs,
            success: (uploadFileRes) => {
                console.log(uploadFileRes.data);
            }
        });
    }
});
