Question

我使用react js（frontEnd），nodejs（backend），也使用通过代理与nodejs连接的java spring端点。我有从nodejs发送formData（file）到spring的问题

我从react js发送，请求主体作为文件的multipart / form-data数组。嵌套js正确。通过http请求，我必须像表单数据一样将其发送到Spring

createApplication(application: any, files: any) {
    var formData = new FormData();
    console.log(files)
    formData.append('application', JSON.stringify(application));

    files.map(file => formData.append('file1', file
    ));
    return this.http.post(
      `${BASIC_URL}/application`,
        formData,
      { headers: formDataHeader },
    );
}

显示错误

TypeError: source.on is not a function

    at FormData.CombinedStream.append (/Users/user/workProjects/b2bsc-backend/node_modules/combined-stream/lib/combined_stream.js:45:37)

我想在控制器的Java端获取此文件

   @PostMapping(consumes = { MediaType.MULTIPART_FORM_DATA_VALUE } )
    public
    @ResponseBody
    ResponseEntity<Object> createApplication(@RequestParam(value = "file1") MultipartFile[] files,
                                             @RequestParam String application,
            UriComponentsBuilder ucBuilder) throws IOException {
}```

从nestjs发送文件
