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

我尝试过以下方法:

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

但这不起作用，但相应的curl命令确实起作用。

您不能显示您的确切代码，因为您提供的curl 命令和您提供的代码有效。查看我的输出:

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

除了窥视 unicode 文字之外，您的代码应该可以完美运行。
