uniapp开发移动端下载文件到本地
代码：uni.downloadFile({
url: this.article.fileUrl,
success(res) {
console.log(res)
if (res.statusCode == 200) {
let filePath = res.tempFilePath; // 下载临时路径
// #ifdef APP || MP-BAIDU || MP-ALIPAY || MP-TOUTIAO || MP-XHS
uni.saveFile({
tempFilePath: filePath,
success(t) {
console.log(t)
uni.showModal({
title: '提示',
content: '文件存储位置：'+t.savedFilePath,
confirmText: '复制位置',
success(e) {
if (e.confirm) {
uni.setClipboardData({
data: t.savedFilePath,
success() {
uni.showToast({
title: '复制成功',
icon: 'none'
})
},
fail() {
uni.showToast({
title: '复制失败'
})
}
})
}
}
})
},
fail() {
uni.showModal({
title: '提示',
content: '文件保存失败'
})
}
})
// #endif
// #ifdef MP-WEIXIN
let FileSystemManager = uni.getFileSystemManager();
FileSystemManager.saveFile({
tempFilePath: filePath,
success(t) {
console.log(t)
uni.showModal({
title: '提示',
content: '文件存储位置：'+t.savedFilePath,
confirmText: '复制位置',
success(e) {
if (e.confirm) {
uni.setClipboardData({
data: t.savedFilePath,
success() {
uni.showToast({
title: '复制成功',
icon: 'none'
})
},
fail() {
uni.showToast({
title: '复制失败'
})
}
})
}
}
})
},
fail() {
uni.showModal({
title: '提示',
content: '文件保存失败'
})
}
})
// #endif
}
}
})app端：
saveFileToLocal(tempFilePath) {
// 获取存储目录
let fileName = tempFilePath.substring(tempFilePath.lastIndexOf('/') + 1);
let savePath = plus.io.convertLocalFileSystemURL(`_downloads/${fileName}`); // 目标存储路径
plus.io.resolveLocalFileSystemURL('_downloads/', (entry) => {
entry.getFile(fileName, { create: true }, (fileEntry) => {
fileEntry.createWriter((writer) => {
writer.write(tempFilePath);
console.log("文件保存成功:", savePath);
}, (e) => console.error("写入失败", e));
});
});
