Uniapp中常用方法封装

以下是在工作中可能需要用到的一些常用方法封装

tools.js

export const isDev = process.env.NODE_ENV === 'development';
export const isIos = uni.getSystemInfoSync().platform === 'ios';
export const isAndroid = uni.getSystemInfoSync().platform === 'android';
// 拨打电话
export const callTel = (tel) => {
    uni.makePhoneCall({
        phoneNumber: tel,
        fail: (res) => {
            uni.showToast({
                title: '拨打失败，请稍后重试',
                icon: 'none'
            });
        }
    });
};
// 下载文件
export const downloadFile = (url) => {
    uni.showLoading({
        title: '保存中...'
    });
    uni.downloadFile({
        url,
        success: (data) => {
            if (data.statusCode === 200) {
                uni.saveFile({
                    tempFilePath: data.tempFilePath,
                    success(res) {
                        uni.showToast({
                            icon: 'none',
                            title: '保存成功'
                        });
                    },
                    fail() {
                        uni.showToast({
                            title: '保存失败，请稍后重试',
                            icon: 'none',
                            duration: 3000
                        });
                    }
                });

                uni.showToast({
                    title: '保存失败，请稍后重试',
                    icon: 'none'
                });
            }
        }
    });
};
// 预览图片
export const previewImage = (urls, current = 1) => {
    uni.previewImage({
        current,
        urls
    });
};
// 保存图片
export const saveImage = (url) => {
    uni.showLoading({
        title: '保存中...'
    });
    uni.downloadFile({
        url,
        success: (data) => {
            if (data.statusCode === 200) {
                uni.saveImageToPhotosAlbum({
                    filePath: data.tempFilePath,
                    success(res) {
                        uni.showToast({
                            icon: 'none',
                            title: '保存成功'
                        });
                    },
                    fail(err) {
                        console.log(err);
                        uni.showToast({

                });
            }
        }
    });
};
// 通过浏览器打开外链
export const openLink = (url) => {
