在播放框架中上传文件时的问题

Question

I tried uploading a file, and placed the file in the "public / images" directory and it worked, but the file I uploaded was zero in size and certainly couldn't be opened

    public Result upload() throws IOException {
    Http.MultipartFormData<File> requestBody = request().body().asMultipartFormData();
    Http.MultipartFormData.FilePart<File> profile_pic = requestBody.getFile("profile_pic");
    String dirPath = "public/images/";      

    if(profile_pic != null) {
        String name = profile_pic.getFilename();
        File file = profile_pic.getFile();
        System.out.println(file);


    File theDir = new File(dirPath);
    if (!theDir.exists()) {
        boolean result = false;

        try {
            theDir.mkdirs();
            result = true;
        } catch (SecurityException se) {
            // handle it
        }
        if (result) {
            System.out.println("DIR created");
        }
    }


    try {

    File filex = new File(dirPath + name.toLowerCase());
    filex.createNewFile();

    file.renameTo(filex);


    }catch (Exception e) {
        // TODO: handle exception
    }
    return ok("File uploaded ");
    }else {
    return badRequest("Eroor");
    }
}

this is my file after upload

I think creating a new file and renaming your old file to that name may cause trouble. I would recommend using the move method, see docs here .

Does your System.out.println(file); print what looks like a normal png file?
