UniApp是一个基于Vue.js的跨平台框架,可以用于构建原生应用,包括iOS、Android等。关于文件上传功能,在UniApp中,你可以使用内置的File API或者uni.uploadFile方法来实现。以下是基本步骤:
1. **获取文件选择**: 使用`uni.chooseFile`方法让用户从本地选择文件,它会返回一个Promise,成功时包含所选文件的信息。
```javascript
uni.chooseFile({
count: 1, // 可以一次选取多张图片,默认值1
sizeLimit: 5 * 1024 * 1024, // 文件大小限制,单位是Byte,默认值无限制
sourceType: 'album', // 选择来源,可选值有['album', 'camera', 'fileManager']
success: function (res) {
var file = res.tempFiles[0]; // 获取到选中的第一个文件
handleFile(file);
},
})
```
2. **处理文件**: 对于选中的文件,你可以调用`uni.showLoading`显示加载提示,然后开始上传操作。
```javascript
function handleFile(file) {
uni.showLoading();
uni.uploadFile({
url: 'your-api-url', // 服务器接收文件的地址
filePath: file.path, // 要上传的文件路径
name: file.name,
headers: {}, // 如果需要添加请求头
method: 'POST', // POST请求默认
formData: {}, // 如果需要发送FormData数据
success: function (response) {
uni.hideLoading(); // 隐藏加载提示
console.log('上传成功:', response.data);
},
fail: function (error) {
uni.hideLoading();
console.error('上传失败:', error);
}
});
}
```
