uniapp 实现上传文件的功能

上传单个文件

<script setup>javascript">const handleUploadClick = () => {console.log("上传文件")uni.chooseImage({success: (chooseImageRes) => {const tempFilePaths = chooseImageRes.tempFilePaths;console.log("用户选择的图片：", tempFilePaths)uni.uploadFile({url: 'http://192.168.234.138:8889/upload', filePath: tempFilePaths[0],name: 'file',success: (uploadFileRes) => {console.log("上传文件成功", uploadFileRes.data);}});}});}
</script>
<template><view><view @click="handleUploadClick" class="button">上传文件</view></view>
</template><style scoped>.button {display: inline-block;background-color: aqua;padding: 10rpx 20rpx;border-radius: 5%;}
</style>

上传多个文件

上传多个文件的功能有个细节需要注意，那就是files不能直接使用读取到的文件列表，官方文档给出如下解释。
在这里插入图片描述

按照官方文档的要求，最终成功的代码如下：

<script setup>javascript">const handleUploadClick = () => {console.log("上传文件")uni.chooseImage({success: (chooseImageRes) => {const tempFilePaths = chooseImageRes.tempFilePaths;console.log("用户选择的图片：", tempFilePaths)let files = []for (let filePath of tempFilePaths){console.log("filePath", filePath)files.push({name: "file",uri: filePath,})}uni.uploadFile({url: 'http://192.168.234.138:8889/uploads', files: files,success: (uploadFileRes) => {console.log("上传文件成功", uploadFileRes.data);}});}});}
</script>
<template><view><view @click="handleUploadClick" class="button">上传文件</view></view>
</template><style scoped>.button {display: inline-block;background-color: aqua;padding: 10rpx 20rpx;border-radius: 5%;}
</style>
