一： 页面
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title> <base href="<%=basePath%>">
</head>
<body>
<form action="<%=basePath%>/aly/aliyun/headImgUpload" method="post" enctype="multipart/form-data">
<input type="file" name="file">
<input type="submit" value="提交">
</form>
</body>
</html>
二： 后台 使用的是spring的文件接受类 使用MultipartFile接收
@Controller
@RequestMapping("/aly/aliyun")
public class ALiYunOSSController { @RequestMapping(value = "/headImgUpload", method = RequestMethod.POST)
@ResponseBody
public String headImgUpload(HttpServletRequest request, MultipartFile file)throws Exception {
String head = updateHead(file);
return head;
} public String updateHead(MultipartFile file) throws Exception {
if (file == null || file.getSize() <= 0) {
throw new Exception("头像不能为空");
}
String nameHz= file.getOriginalFilename(); //上传的文件名 + 后缀 如 asd.png
String type = "";
if(nameHz.contains(".png") || nameHz.contains(".jpg")){
type="/img";
}
if(nameHz.contains(".mp4") || nameHz.contains(".ogv")){
type="/video";
}else {
type="/file";
}
OssClienUtils ossClient = new OssClienUtils();
String keyName = ossClient.uploadImg2Oss(file,type);
String imgUrl = ossClient.getImgUrl(keyName); return imgUrl;
} }
