Feign下载文件 [英] Feign for downloading file

问题描述

我试图找到一种简单的方法来使用 Feign 下载 csv 文件(保留文件名).

I am trying to find a simple way to use Feign to download a csv file (retaining the filename).

最简单、最干净的方法是什么?

What is the easiest and cleanest way?

feign-form github 页面上的多部分解决方案很冗长，对我不起作用.

The multipart solution on the feign-form github page is verbose and isn't working for me.

感谢任何帮助.

推荐答案

Feign client:

Feign client:

import feign.Response;

@FeignClient(value = "some-service")
public interface Client{
   @RequestMapping(method = RequestMethod.GET, value ="/download")
   Response downloadFile();
}

Feign Client 的使用:

Usage of Feign Client:

final Response response = client.downloadFile();
final Response.Body body = response.body();
final InputStream inputStream = body.asInputStream();

您应该检查响应是否为 200，如果不是，则抛出异常.文件名应在标题中

You should check if response is 200, if not, throws exception. File name should be in headers
