优点:无需第三方组件,成本低
缺点:代码复杂,需手动处理文件边界与安全校验
<% ' 创建组件实例 Set Upload = Server.CreateObject("Persits.Upload.1") Upload.SetMaxSize 5*1024*1024, False ' 限制5MB Upload.OverwriteFiles = True ' 允许覆盖同名文件 Upload.Save Server.MapPath("upload") ' 保存路径 ' 获取文件信息 Response.Write "文件名:" & Upload.Files("file1").FileName & "<br>" Response.Write "大小:" & Upload.Files("file1").Size & "字节" %>
组件下载:AspUpload 2025版
优点:支持表单与文件混合上传,功能强大
注意:需配置IIS文件夹权限(IIS_IUSRS
用户需完全控制)
<input type="file" id="uploader" multiple accept="image/*"> <div id="preview"></div> <script> document.getElementById('uploader').addEventListener('change', function(e) { const files = e.target.files; files.forEach(file => { const reader = new FileReader(); reader.onload = (e) => { document.getElementById('preview').innerHTML += `<img src="${e.target.result}" width="100" style="margin:5px">`; }; reader.readAsDataURL(file); }); }); </script>
const formData = new FormData(); Array.from(files).forEach(file => { formData.append('files[]', file); }); fetch('/upload.asp', { method: 'POST', body: formData }).then(response => { alert('🚀 上传完成!'); });
If Not InStr(1, Upload.Files("file1").ContentType, "image/", vbTextCompare) > 0 Then Response.Write "❌ 仅支持图片格式!" Response.End End If
Blob.slice()
实现大文件分片传输 CREATE TABLE Images ( ID INT PRIMARY KEY IDENTITY(1,1), FileName NVARCHAR(255), FilePath NVARCHAR(512), Size INT, UploadTime DATETIME DEFAULT GETDATE() );
Dim tags Set http = Server.CreateObject("MSXML2.ServerXMLHTTP") http.open "POST", "https://api.openai.com/v1/images/analyses", False http.send "{""image_url"":""" & imgUrl & """}" tags = http.responseText ' 获取AI生成的图片描述
路径权限问题:
👉 右键上传文件夹 → 属性 → 安全 → 添加IIS_IUSRS
用户并勾选“完全控制”
中文文件名乱码:
Response.Charset = "UTF-8" fileName = Server.UrlEncode(Upload.Files("file1").FileName)
大文件上传失败:
👉 修改IIS配置:<requestLimits maxAllowedContentLength="104857600" />
(100MB)
