python - 使用 Python 请求复制 Curl 命令

Question

将以下内容转换为 Python 请求调用的语法是什么？

curl -F file=@/your/data.csv http://host/ingest

我尝试了以下方法：

 files = {'file': ('injestable_file', open(temp_file, 'rb'))}
 requests.post(url,files=files)

但这不起作用，但相应的 curl 命令确实有效。

You must not be showing your exact code because the curl command you provide and the code you provide works. See my output:

~ curl -F foo=bar -F file=@setup.py https://httpbin.org/post

With the exception of the unicode literals peeking through, your code should work perfectly.
