REST-Assured、SpringBoot 文件上传

通常我们在向服务器传输大容量的数据时（译者注：比如文件）会使用multipart表单数据技术。rest-assured提供了一种multiPart方法来辨别这究竟是文件、二进制序列、输入流还是上传的文本。表单中上传一个文件可以这样

（官方案例）：
given().
        multiPart(new File("/path/to/file")).
when().
        post("/upload"); 

自己写的SpringBoot controller如下：
  @PostMapping("/file/upload")
    public String upload(@RequestParam Map<String, String> paramMap, @RequestParam("file") MultipartFile file1) throws IOException {
        String url = paramMap.get("url");
        Response response = given().multiPart(CMD.MultipartFile2File(file1)).params(CMD.getParams2(paramMap)).post(url);
        System.err.println("实际返回结果::" + response.asString());
        return response.asString();
    }


MultipartFile2File方法如下：
 public static File MultipartFile2File(MultipartFile file) throws IOException {
        // 获取文件名
        String fileName = file.getOriginalFilename();
        // 获取文件后缀
        String prefix = fileName.substring(fileName.lastIndexOf("."));
        // 用uuid作为文件名，防止生成的临时文件重复
        String uuid = UUID.randomUUID().toString().replaceAll("-", "");
        File upload = File.createTempFile(uuid, prefix);
        // MultipartFile to File
        file.transferTo(upload);
        return upload;
    }

前端：<form action="http://localhost:8888/file/upload" method="post" enctype="multipart/form-data">

效果如下：

接口返回（上传成功）：

{
code: "1",
msg: "操作成功",
data: "0a147efcaf774461a399e82393ce77e9",
success: true
}
