R httr误差403

Question

我在python中有一个代码，它用下面的代码将文件上传到服务器

 with open(file_path, 'rb') as fp:
     r = requests.Request('PUT', signedRequest, data=fp.read())
     prepped = r.prepare()
     s = requests.Session()
     resp = s.send(prepped)

在R中，我使用以下代码作为替换

PUT(url = signedRequest,
    body = upload_file(path = file_path),verbose()
   )

但这是在抛出错误

HTTP/1.1 403 Forbidden

在requestbin中，请求被接收为

对于Python

Cf-Connecting-Ip: ****
Host: requestb.in
Connect-Time: 1
Total-Route-Time: 0

代表R

有什么建议吗？

Answer 1

很难说服务器在抱怨什么，但是如果我们比较这两个请求，我们就会发现在内容类型和用户代理方面存在差异。

您可以使用

upload_file(path = file_path, type="")

您也可以通过传递

user_agent("")

作为PUT()的参数
