pure javascript file upload 테스트 본문
반응형
기능을 테스트하며 기록을 남긴다.
back-end는 spring 4.3.9.RELEASE를 사용했다.
commons-fileupload를 사용하기 위해 pom에 dependency 추가
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>1.2.2</version>
</dependency>
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.6</version>
</dependency>
spring dispatcer설정(xml방식)에 CommonsMultipartResolver를 추가
<bean class="org.springframework.web.multipart.commons.CommonsMultipartResolver" id="multipartResolver">
<property name="defaultEncoding" value="UTF-8" />
<property name="maxUploadSize" value="262144000" />
<property name="maxUploadSizePerFile" value="262144000" />
<property name="maxInMemorySize" value="0" />
</bean>
테스트용 Controller를 추가하고 RequestMapping 처리
@RequestMapping(value = "/upload", method = RequestMethod.POST)
@ResponseBody
public String upload(@RequestParam("mediaFile") List<MultipartFile> files, @RequestParam("user") String user, HttpServletRequest request, HttpServletResponse response) throws Exception {
Gson gson = new Gson();
JsonObject obj = new JsonObject();
String uploadDir = request.getSession().getServletContext().getRealPath("/")+"resources";
logger.info("------------------> {} , {}", user, uploadDir);
if(files.size()>0){
try{
for (MultipartFile file : files){
if(!file.getOriginalFilename().isEmpty()){
logger.info("{}",file.getName());
logger.info("{}",file.getOriginalFilename());
byte[] bytes = file.getBytes();
File dir = new File(uploadDir);
if(!dir.exists()){
dir.mkdirs();
}
File uploadFile = new File(dir.getAbsolutePath() + File.separator + file.getOriginalFilename());
BufferedOutputStream uploadStream = new BufferedOutputStream(new FileOutputStream(uploadFile));
uploadStream.write(bytes);
uploadStream.close();
}
}
obj.addProperty("error",-1);
} catch (Exception e) {
obj.addProperty("error",1);
throw e;
}
}
return gson.toJson(obj);
}
html view
fetch는 아직 progress를 지원하지 않는다.XMLHttpRequest는 upload.onprogress로 지원.
이미지와 동영상파일을 선택했을때 base64로 연결하였다.
업로드할때 file로 변환 후 FormData에 추가
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport"
content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Image & Video Base64 Upload Test</title>
<style>
button {
margin: 2px;
}
ul {
list-style-type: none;
}
progress {
margin-left: 10px;
}
</style>
</head>
<body>
<div>
<ul>
<li>
<button id="btnSelectImageFile">이미지선택</button>
<button id="btnUploadImage">이미지업로드</button>
</li>
<li>
<button id="btnSelectVideoFile">동영상선택</button>
