准备前端环境
安装 nodejs 自行去nodejs 官网下载，我们主要是为了使用 npm 工具。 安装淘宝镜像，如果是在国内，下载镜像很慢，所以使用国内的镜像 。
sudo npm install -g cnpm --registry=https://registry.npm.taobao.org
安装 vue-cli 工具 因为我们前端使用的 vue，所以需要安装vue-cli
cnpm install -g @vue/cli
创建项目
vue create xiaotuwo
添加 antd 依赖
cnpm install ant-design-vue --save
启动
cd xiaotuwo
npm run serve
访问，能够访问 HelloWorld 页面说明我们环境准备成功了。
http://localhost:8080
编写前端代码
content/index.vue 里面就可以了，然后修改 a-upload 的 action 为自己的服务器地址即可，本地测试就是http://localhost:8887/api/images/upload，下文中也有配套的服务端代码。
handlePreview方法里面我添加了一个复制链接的逻辑，可以轻松的点击预览的时候复制图片链接，这样方便的把网址放入其他地方进行使用。his.$message.success('复制图片链接成功');
document.addEventListener("copy", function copyCall(e) {
e.preventDefault()
e.clipboardData.setData("text/html", file.preview)
e.clipboardData.setData("text/plain", file.preview)
document.removeEventListener("copy", copyCall)
})
服务器端环境准备
xiaotuwo.cn-bj.ufileos.com 留存备用。
编写服务端代码
MultipartHttpServletRequest 接收到前端的 file 文件，调用 uCloudProvider进行上传。@PostMapping({"/api/files/upload"})
@ResponseBody
public FileDTO upload(HttpServletRequest request) {
FileDTO resultFileDTO = new FileDTO();
MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
MultipartFile file = multipartRequest.getFile("file");
long start = System.currentTimeMillis();
try {
if (file == null) {
resultFileDTO.setStatus("error");
}
FileDTO fileDTO = uCloudProvider.uploadWithExpired(file.getInputStream(), file.getContentType(), Objects.requireNonNull(file.getOriginalFilename()));
log.info("UPLOAD_FILE_EXPIRED|ip:{}|referer:{}|url:{}|cost:{}", getIpAddress(request), request.getHeader("referer"), fileDTO.getUrl(), System.currentTimeMillis() - start);
executorService.submit(new UCloudScanner(fileDTO, uCloudProvider, executorService, 1));
resultFileDTO.setName(fileDTO.getName());
resultFileDTO.setUrl(fileDTO.getUrl());
resultFileDTO.setThumbUrl(fileDTO.getUrl());
resultFileDTO.setStatus("done");
} catch (Exception e) {
log.error("UPLOAD_FILE_ERROR", e);
resultFileDTO.setStatus("error");
}
return resultFileDTO;
}
