Question

我正在尝试翻译此cURL请求：

curl -X POST "endpoint" -H 'Content-Type: multipart/form-data' -F "config=@conf.ttl"

到目前为止，我已经得到了这个：

requests.post(
     endpoint,
     headers={"Content-Type": "multipart/form-data"},
     files={"config": ("conf.ttl", open("conf.ttl", "rb"), "text/turtle")}
)

但它并不像预期的那样有效。我错过了什么？

您不应该明确设置“multipart / form-data”。它正在覆盖请求标题集的所有其他部分（“multipart / form-data; boundary = 4b9 ...”，）。无需设置标头，请求将为您执行此操作。您可以在下面的示例中看到请求标头（requests.headers）。你可以看到

idx = np.isfinite(x) & np.isfinite(y)
ab = np.polyfit(x[idx], y[idx], 1)

给出：

import requests
endpoint = "http://httpbin.org/post"
r = requests.post(
     endpoint,
     files={"config": ("conf.ttl", open("conf.ttl", "rb"), "text/turtle")}
)
print r.request.headers
print r.headers
print r.text

带有显式标头的代码会向同一网址发送错误。

cURL对Python的请求（使用multipart / form-data）
