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
}
