但上图的字段名，类型需要根据不同接口填写，如某服务接口：

因而对应的上传代码如下：

# 输出参数：请求响应报文
import requests
request_url = 'https://XXXXX/file-upload'
head = {

}

fl = open('test.png','rb')
files = {'files': ('test.png', fl, 'application/octet-stream', {'Expires': '0'})}  #字段名files 以及类型和application/octet-stream 和抓取到的接口一致</pre>

r2 = requests.post(request_url, headers=head, files=files)

print(requests.Request('POST', request_url, headers=head, files=files).prepare().body.decode('ascii'))  #可以打印出来真实请求的 字段名 以及类型等信息，如果和抓取接口不一致，调整</pre>
